What do you say?? I Test It?
use for 10 years, products barthdal and they have never failed me
to be honest, using many types of olive oil that I always look at, and the specification ( acea mb etc etc) but on aditivi work only with a company called protek, and for a long time that we work and has a wide range of products that revolve around the world of engines , and to this day I am fine
I appended to the topic to give my ideas and assumptions:
So I wanted to start immediately which actually? there are oils better and worse? we can also say of course
that there are oils suitable and not suitable. Also I don't want to express opinions on brands and so on since?
after you read what I'm about to tell you will you understand it from you.
When you buy a olive oil, the average user goes to check out the specs that are listed on the packaging
without knowing that in reality? what are the mean, being unaware that there are many and
unknown characteristics that are not reflected in reality? very important.
The oil is divided into 4 categories:
- Mineral: ? the refining base oils, it allows you to have very good parameters combustion but low ****lli lubrication
- Synthetic: are side-by-side to the mineral oil of the chemical PARTICLES that reduce "Achilles heel" of the mineral oil to the detriment of his strengths
- Semi-synthetic: The composition between mineral and synthetic oil increases (the % ? the choice of the manufacturer) with their consequences as mentioned before
- Synthetic: Fully synthetic, its characteristics are inverse to the mineral.
Of course, in the two extremes (Mineral and Synthetic) the first experiments had nothing to do with the results obtained with the passing of the years,
in fact, the first minerals had all the parameters really, really bad (that's why? the breakage of the first vehicle).
Let's start now with the specifications defined, by law, on the packaging, with descriptions:
SAE (Society of Automotive Engineers)
Through this classification, allows you to understand "approximately" since the solution is smooth (maximum value 0) or viscous (maximum of 60) at different temperatures (non-operating).
To understand how well does the oil to temperatures outside "low" is given a code (W= winter) next to a value (for example:10, then it becomes 10W)
these values do not indicate the actual temperature, but bens? indicate a range of standardised, calculated on the 3 parameters (not listed on the box and that spiegher? below):
-Pour Point (Slide Show)
-Viscosity? Kinematics (Relative) to 40 C? expressed in cS (CentiStokes) that the other does not ? the time (in Seconds "s"), in which the oil can cover an area (mm^2)
-Index of Viscosity?
To understand how it behaves and the oil to outside temperatures "High" are not placed initials, and then will be? to display a value such as: 30, 40 etc
The value of "hot" ? same as "cold" does not indicate the actual temperature, but a range of standardised, calculated on 3 parameters:
-Flash Point (the Point of infiammabilit?)
-Viscosity? Dynamic at 100 C? expressed in cP (CentiPoise), which is the quantity? (grams "g"), in which the oil can cover an area (cm^2)
-Index of Viscosity?
There are 2 main categories of the classification SAE:
-Unigradi (Ex: 5W, 15W, 40[W], etc.) used until the late '50's/'60's and is still used in races, drag;
-Multigradi (E.g. 0W-30, 10W-40) these have taken over since? that can be used throughout the year
Really?
For those who, like me ? interested, passionate, and has studied a bit in the field, when reading the labels is to laugh.
Since? the classification SAE serves only to summarize all the characteristics of the oils, and rightly so, for people who don't know what the deal is
not knowing that in most of the times seem really made the case, and I explain the why?:
Reading the datasheets (assuming that to be true, but by giving us a bit of "tara") some times I have come across
in oils with ****llo SAE lower (E.G. 15W-40) were much more? performing one of ****l higher (EG:10W-40),
therefore, when a manufacturer provides a certain gradation not ? absolutely true that taking a gradation
lower you risk of ruining the engine, on the contrary can? happen to get one of the highest quality, so even by this factor
you can't figure out if the manufacturer creates a lot of oil pi? "performance" with gradations pi? low (nothing prohibits the contrast and/or with oils and top of the range
do not get results much more? "consistent/best" with the brand previously compared).
Of course, as I said at the beginning there ? a distinction between oils suitable, since? if a manufacturer provides that for your vehicle, the oil for the hot areas
must be a 15W-50 and the cold zones a 5W-30 and you are in Canada, where the temperature drops well below -30 C? and you want to use the oil prescribed
from the house...well I would be a lot of questions to use a 5W-30, I informerei rather on his "Pour Point", no? not been too far behind to what is prescribed, but
on what ? really suitable or not. One important thing ? use for the entire life of the engine, the usual oil, why? if any change were to be changed is the viscosity? that the quality?
the life of the engine caler? dramatically...and the avr? way to prove this to you more? next. Another consideration ? that an oil with a differential viscosity? too high does not really
his work why? its characteristics would tend to be too much different then a lot "fragile".
The API (American Petroleum Institute)
This classification ? one of the most? "true" and pi? severe, it provides a test to evaluate the quality? oil in the field of resistive chemical/Tax, additives, and other parameters.
To understand if you're taking an oil quality? you must interpret the classification:
First of all, the classification is divided into 2 parts consist of 2 letters let's take an example:
API SL/CF in this case (the pi? full) we have a oil ? prepared for 2 types of vehicles, why? the "S" indicates that ? suitable for Petrol engines
instead of "C" indicates that ? suitable for Diesel engines the second letter indicates the ****highest quality for Petrol engines (S) go from "A"(now obsolete)
the "N" the best for now; instead, for the Diesel classification ? pi? complex since? you go from A (now obsolete)
the "I" with various variants on some of the classifications that indicate a particular application type marine engines.
Another letter with their respective features ? the "T"? specification for two-stroke gasoline and as quality? we arrived to a standard now unified by a few decades.
ACEA (Association of European Automobile Manufacturers) ? the "competitor" API, it provides a breakdown of the categories of vehicles, namely:
For Gasoline engines use the letter "A" followed by a number ranging from 1 up to 5
A1= Fuel Economy
A2= Obsolete
A3= High Performance
A4= For Future use
A5= Fuel Economy and High Performance
For the light Diesel Engines (passenger cars) uses the letter B:
B1= Fuel Economy
B2= Obsolete
B3= High Performance (Indirect Injection)
B4= High Performance (Direct Injection)
B5= Fuel Economy and High Performance (Both Injections)
For engines with DPF/CAT/DPF and then with post-treatment of emissions the letter "C"
C1= Fuel Economy and high performance engines that require an oil with a low viscosity?
C2= Fuel Economy and high performance
C3= High Performance
C4= High Performance Protective (HTHS>3,5 spiegher? following this parameter)
For Heavy duty Diesel engines (Trucks), letter And
E1= Obsolete
E2= Medium Performance
E3= Euro II
E4= Euro II and III Semisint/sint longlife
E5= Euro III Mineral
E6= Euro IV Semisint/Sint longlife
E7= Euro IV Mineral
JASO (Japanese Automotive Standards Organization)
This, according to me, ? the pi? "useless", it ? present in oils for motorcycles, the classification
provides that in these oils are addtivi that break down the additives "sliding" to not slip the clutch in an oil bath. This additive ? been inserted after the classification API SG.
The quality? is expressed by the name, BUT in which the inside covers the MA1(the worst effect of anti-friction) and MA2(best effect of anti-friction),
so the order of quality ? the following MA>MA2>MA1.
Really?:
Why? at the beginning I said that ? useless? well debunk each myth. There are various strands of thought:
- C'? who says that bikes should only be used in the oil for motorcycles with classification JASO and not ? can use oils for cars, why? the performance is higher (rpm, hp, etc..)
- C'? those who claim that the oil for motorcycles go well on the car
Then the correct answer ?: The oil for the car is fine even on the motorcycles provided that it meets certain characteristics, of course.
As explained before, the problem of the clutches in an oil bath ? slippage due to the presence of the anti-friction additives, which, however, are not present before classification
SH. These friction modifiers are not present in the automotive oils with the classification ACEA A3, unfortunately this data ? a lot of hidden just to allow the trade to sell
the oil for motorcycles and even at a price really high! You should avoid oils with friction modifiers and high differential viscosity? (example 5W50 or 10W60). The presence on the latter of high quantity? polymer linear organic (see Additives), sensitive to the actions of cutting caused by the gears, can result in excessive variations of the viscosity? during the use.
Now someone storcer? the nose why? I have not confirmed the factor "performance" well then I ask you in front of a question:
Do you think a Mazda RX8 that oil goes there? eheh oil by machine or by bike? after all ? a engine a little "complex" since it has almost 10K rpm
and a power cubic capacity is certainly superior to a bike, and the oil bath clutch. However, there must be (at last update) the 10w-50 as recommended by the house.
There are a variety of other classifications, CCMM, for example, but are not pi? used.

INTERNATIONAL MANUFACTURERS ' SPECIFICATIONS ( TAKEN FROM THE SITE SELENIA)
Next to the specifications issued by international organisations and manufacturers ' associations, with the aim? to standardise the minimum requirements to which a lubricant must comply with to be able to be used without problems on different engines, there are specifications issued by individual manufacturers. They define the particular characteristics that a lubricant must possess in order to be considered ideal for a particular type of engine. It is an authorisation given by the manufacturer to the manufacturer of the lubricant, to be able to boast a product of an approval mark, which makes it particularly suitable for cars of a given brand.
The pi? well-known are definitely the specifications issued by Volkswagen, Mercedes Benz, BMW, FIAT, GM.
VOLKSWAGEN SPECIFICATIONS
The specifications laid down by Volkswagen, attesting to the specific quality? an engine oil that make it
suitable for use on cars are divided into three large groups:
I. Specifications for dual lubricants
500.00 for petrol engines and diesel NA
501.01 for petrol engines and diesel NA
Require an oil change every 15,000 KM but are now obsolete because? provided only for approved oils prior to March 1997
II. Specifications for lubricants for petrol engines
502.00 for gasoline engines, high-performance, change every 15,000 km
503.00 for petrol engines with a range of extended exchange (30,000 km),low viscosity?
503.01 for petrol engines with a range of extended exchange only AUDI
504.00 for gasoline engines, Euro IV
III. Specifications for lubricants for diesel engines
505.00 diesel engine with intercooler, oil change every 15,000 km
505.01 for diesel engines of cars including engines of the new generation, with a single injector pump, change every 15,000 km
506.00 for diesel engines of cars, with prolonged oil change interval over 50,000 km, not for use on engines with single injector pump. The change is indicated by the electronic service indicator (WIV).
506.01 similar to 506.00, with increased protection against wear, change to 50,000 km, for all diesel engines. It is the specification of long-life oil for AUDI A2 1.4 TDI with engine with single injector pump. Should not be used where required, the VW specifications 503.00/506.00/505.01/505.00/502.00.
507.00 for diesel engines Euro IV
SPECIFICATIONS MERCEDES BENZ
The name of the MB specifications derived from the schema of the Bluebook Mercedes, divided into numbered paragraphs and pages. It is used by dealers to identify the products certified by the manufacturer and their correct application on the engines.
229.1 For petrol and diesel engines. Quality? minimum required ACEA A2/B2 with additional limits on the engine.
229.3 For petrol and diesel engines. Quality? minimum required ACEA A3 / B3 / B4, MB 229.1. Pu? only certify oils 0/ 5-W-x. Are provided for additional tests on DB engines.
229.31 For new generation diesel engines. For lubricants with features mid SAPS and SAE 5W-30 grade.
229.5 Exchange up to 50,000 KM. Quality? minimum required ACEA A3 / B3 / B4. Pu? only certify oils 0/5 /l0 W-30 /40/50. You are using for the new MB cars with ASSYST system (based on number of starts, operating time of the engine, mileage and type of lubricant).
229.51 for gasoline and diesel engines of the new generation. For lubricants with features mid SAPS and SAE 5W-30 grade.
BMW SPECIFICATIONS
The BMW specifications are mostly known as "Long Life". There are three categories of products, passing certain tests, can be reach-specific oil change interval.
"BMW Special Oils," 1996
The minimum requirement ? ACEA A3/B3. You add the test M42 required to allow use all year product grade 0W/5W/10W - x.
"BMW Long Life Oils," 1998
The minimum requirement ? A3/B3 and ? can be combined with the following viscosimetric grades: 0W/5W/10W-30/40. The oils that pass the test M44, allow extended change intervals, up to 20,000 Km or two years.
"BMW Long Life" 2001
The minimum requirement ? ACEA A3/B3 and the viscosimetric grades that can indicate this specification are 0W/5W/10W-30/40. The test M44 in the new version, provides oil change intervals of up to 20/40.000 or two years. It is mandatory for new cars that require Long Life 01 and pu? replace the previous ones.
"BMW Long Life" 2004
The minimum requirement ? ACEA A3 and BMW Long Life 2001. Applicable to lubricants of the new generation with high volatilit? and average values of sulphated ash, sulphur and phosphorus.

Define the characteristics to be complied with by the lubricants used in engines with Otto and Diesel cycle for the first filling and during exercise. The norm ? consisting of a series of tests in the laboratory and on the engine to assess the ****th e performance of the lubricants.
The laboratory tests qualify the lubricant evaluating the viscosity?, the point of cold flow,the tendency to produce foam, the corrosion on the copper foil, the behavior of the tires and the oxidation resistance.
The engine tests assess, on some engines, both diesel and gasoline, which are representative of the pi? advanced technologies of Fiat Auto, the performance of lubricants in terms of sticking rings, piston deposits, wear and also oil consumption.
The lubricants that exceed the qualification, are marked with an Approval number.
GM (OPEL)SPECIFICATIONS
The manufacturer requires for all vehicles, european specification ACEA A3-98, B3-98 with different viscosimetric grades SAE 0/5/10 W - 30/40 with oil change at 15k km or 1 year with Euro 2 engines (built-cio? before 2001) and 30 thousand miles or 1 year with Euro 3 engines.
Opel also introduced in 2002, the Opel Long Life Service Oils (starting from the Vectra, model year (2002), a variable oil change interval that can? reach 30 thousand km, or 2 years for petrol engines (specification GM-LL-B-025) and 50 thousand km, or 2 years for diesel engines 2.0 and 2.2 DTI(GM-LL-A-025).
The cars that use the Opel Long Life Service Oils must exceed the specifications ACEA A3, B3, B4, and the evidence Opel B040 2095 HTHS >2.9 and B040 2098 for lubricants with HTHS >3.5.
This system of qualification of lubricants ? been developed with the support of independent German laboratories that perform engine tests (for wear, deposits, and F. E.), or in the wearing, using Opel's procedures.
I WOULD SAY NOW MOVING ON TO WHAT IS NOT WRITTEN ON THE LABELS
At the beginning of the article I talked about some of the very important parameters, flash point, pour point, etc., but what are these strangers? andiamoli to analyze:
-Viscosity? Kinematics (Relative) to 40 C?: expressed in cS (CentiStokes) that the other does not ? the time (in Seconds "s"), in which the oil can cover an area (mm^2), the lower ? the value
and before the oil gets to lubricate the upper parts of the engine as the valves, especially those of the modern cars that are with hydraulic lifters, (in fact, cold-make noise)
-Viscosity? Dynamic at 100 C?: expressed in cP (CentiPoise), which is the quantity? (grams "g"), in which the oil can cover an area (cm^2)? the value
the more the engine is protected at high temperatures (very IMPORTANT)? this data is worth a lot less of the ratio of HTHS
-Index of Viscosity?: It is based on the two parameters above, pi? ? high and pi? the oil ? of excellent quality? and is resistant to various stress etc..
-HTHS (High Temperature, High Shear): ? a most important value, it describes the thickness of the oil, or more? the oil has a thick film pi? ? a protective oil
less ? often and less protects. The starting value ? 3.5 this means that a value of pi? high of 3.5 ? considered to be very protective to below that threshold
it is considered an oil and Fuel economy, this is because? a film less often, sliding bodies more? easily in spite of the protection, and vice versa, in thick films,
the cio? a thick film protects the pi? but does consume even more?. Personal opinion I prefer to have a HTHS value of pi? the top for? not too much ca. 4.1 to the maximum.
Of course, a high HTHS does it mean ? an oil-resistant "moments of cutting"
-Pour Point (Scroll): indicates the temperature at which the oil begins to crystallize, is called the parameter of the pumping, which is important for those who live in the areas really cold)
-Flash Point (the Point of infiammabilit?): Indicates the temperature at which the oil ignites, (important value for those vehicles turbocompresse, especially heavily processed)
-Sulphated ash (% per gram): a low value indicates a combustion ir? clean (for the car, the maximum value of 1.5% for the motorcycle 1,1/1,2%)
-Longlife: less Presence of detergent additives, negative fact about race cars
There are many other parameters have an influence on the very bottom.
LET US NOW TURN TO THE VARIOUS ADDITIVES PRESENT IN THE OIL:
Type: Improvers of the index of viscosity?
Chemical nature: linear Polymers of organic compounds.
Function: to Make the viscosity? oil is less sensitive to temperature variations.
Action: polymers, inserted in a base oil, raise somewhat the viscosity? hot and only cold. Therefore, the oil is admixed with an index improver has a viscosity curve?-temperature less inclined and moved to a p? pi? at the top of the curve of the base oil.
Type: Detergent
Nature chemistry: Compounds and metal-containing organic elements such as calcium, sulphur, phosphorus, zinc, etc.
Function: Prevents the formation of "deposit" on the organs of metal, in the presence of high temperatures.
Action: The oxidation products as they are formed are rendered soluble or kept in suspension in the oil, while the particles of soot or coal are covered with these additives and made harmless.
Type: Dispersants.
Nature chemistry: Compounds, metal-organic or polymeric materials, not of metal.
Function: Press the "sludge" mushy finely dispersed in the oil.
Action: Prevent the agglomeration of the particles, contaminants in the oil, and consequently the formation of sludge mushy.
Type: Improvers pour point.
The chemical nature of organic Compounds in complex paraffinic-naphthenic.
Purpose: to Lower the temperature at which the oil loses its smoothness.
Action: Act on the crystals of paraffin, which are formed in the oil for cooling; by surrounding them, they slow down the formation of the crystal lattice, which prevents the oil to flow.
Type: Antioxidants.
The chemical nature of organic Compounds such as phenols or amines, sulfur-containing, phosphorus -, nitrogen -, barium, zinc, etc.
Function: Prevent the incorporation of oxygen in the oil.
Action: React chemically with the oxygen, even before this attack the oil, forming harmless compounds soluble in the oil.
Type: anti-Corrosive and anti-rust.
Chemical nature: complex organic Compounds containing sulphur, phosphorus, nitrogen, etc.,
Function: Prevent corrosive attack of the metal alloy.
Action: Prevent the development of acidic substances, or to form protective layers on the metal surfaces.
Type: untuosit?.
The chemical nature of organic Compounds oxygen-containing polar groups.
Function: Reduce the coefficient of friction between the moving parts in conditions of imperfect lubrication.
Action: Due to the effect of "polar" the oil molecules are arranged perpendicular to the metal surface anchoring itself firmly and compensating in this way the small lubrication services
Type: Anti-Wear Additives.
Chemical nature: Tricresilfosfato, ditiofosfato zinc etc.
Function: Reduce the wear and tear on the mechanical.
Action: Melt at relatively low temperature filling and ****llando, for subsequent solidification, the grooves on the metal surfaces so as to improve the contact between the moving parts.
Type: extreme pressures.
Chemical nature: organic Compounds containing sulfur, lead, phosphorus, chlorine, molybdenum, etc.,
Function: Avoid welding and the resulting strappamento between the asperit? the surface of the organs in movement.
Action: React chemically, high temperature, with the asperit? surface of the bodies in movement, forming a locally-substances with a low coefficient of friction and promoting any tranciamenti of the ridges instead? their tear erratic and violent.
Type: Of adhesion?.
Chemical nature: organic Polymers of high molecular weight.
Purpose: to Impart to the oil features anti-drip and splash-proof.
Action: significantly Increase the adhesive power of the oil bodies to be lubricated.
Type: Anti-Foam.
Chemical nature: Polyester, polymers and silicones.
Function: Prevent the formation of stable foam in the oil due to the inclusion of gas.
Action: Reduce the so-called "interfacial tension" between the gas bubbles and the oil, etc? the gas bubbles formed in the oil, which can be grouped in the bubbles of a larger size, they can reach more people? quickly the free surface, dissolving in the air.
Type: Emulsifiers.
Chemical nature: Soaps of fatty acids, sulphonic acids and naphthenic.
Purpose: to Encourage the formation of a stable emulsion oil-water (fluids, cutting, laminating, some additives, anti-rust).
Action: Serve as a link between the water molecules and the molecules of the oil (water and oil, alone, are in fact the liquid is not miscible).
NOTE: some of the additives represent pi? functions: for example, some have properties at the same time? antioxidants, anti-corrosion and anti-wear; others are miglioratrici index pour point, and they have properties? detergents, etc.,
N. B. 2: The use of additives, especially in the oils already? very additives(SI, SL, etc), ? not recommended since? not ? guaranteed really their
compatibility? and efficiency, or, in some cases, the additive can? not emulsionarsi completely in the oil and "set"
creating congestion or compounds that are very hard, which would cause significant damage to the engine, in the case of further
additivamento or also called anti-additivamento the oil could lose its properties? (EX: Oil, without amtiattrito A3 and
eventualamente fuel economy, by inserting an additive anti-friction there would be a heavy loss of the protective film, and then for any premature wear of the organs)
The present here ? for educational purposes only and should not be taken as a guide only and/or as liquid gold, I exempt from any liability

Good explanation
thanks a lot! it took me quite a while to write it.
I hope that this was helpful for those looking to buy
the oil is right for their vehicle.
if there are imprecisazioni or faults please let me know!
