Poll: Your best engine oil + any additives

[V.V.]

Renox makes great products even if they are little favorable to the use of additives of third-party lubricants gi? very added as the RP on which, on the contrary, I have been able to ascertain, at least on the sample that I had between the hands, not veracity? many of the basic features (it should also be said, to?, the campio came from the market of eBay ^_-)! Sincerely, in place of the Royal Purple, I prefer to work on different alternatives, but they are part and little objective therefore t address here to get a good culture on lubricants:

On the Italian market, buying the oil from a certain source (official distributors of the brand, specialized in the field of lubrication), there are few alternatives, in my opinion, in terms of brands, and products. Personally I have the family car to Motul, Castrol and vehicles pistaioli to the Prorace or 300V of Motul. Then it all depends on where you put the lubricant, from the required specifications, and the whole apparatus...

[garret]

the oil we use comes directly from the renox, as additives, of the motul I've heard very well, you say that the oils sold on ebay are unreliable?

[garret]

the pakelo what do you think?

[V.V.]

With the Pakelo I have very little experience and I don't feel I expressed a final opinion; consider it a good oil, in the best cases, comparable to a good 300V and change intervals are very close together, with good capacity? detergents but poorly dispersing IMHO.
With regard to the purchases on eBay instead, I can tell you that some manufacturers have more? lines of the same product which are sold at different prices. The line pi? economic, that while respecting the stated specifications, however, has a quality? bottom lines destined to the shelves is usually conveyed in the market of the Dealer On-Line that make large volumes throughout the territory and that more and more? spent are paid on commission, they have price lists that are specific and different from those for the conventional market. Usually for OnLine purchases I try to work on the Shop authorized by the manufacturer of my interest, or otherwise recognized, preferably when making purchases abroad, where trade policies are very different from the Italian ones! The fact remains that the Renox ? an excellent company, in my opinion, highly stable, and managed by people with the so-called, even though the products that they sell are not to my liking and do not satisfy my needs.
Keep in mind, finally, that many retailers are not aware of the distinctions, which the producers operate in both markets, "OnLine"/"Shop physical" why? the products apparently are the same! Just for the sake of completeness, I invite you to take a ride on ****** using the following Key Words: "engine oil, counterfeit". The latter ? one of the main reasons why I am wary of purchasing this kind of through this trade channel.

I could ask you why you have a culture that is so great about lubricants??are you a dealer??

[V.V.]

No, or better, not more?, I have worked in the industry and I have continued to maintain relationships with former colleagues of the laboratory "research and development" !

[munro]

interesting...can you tell me comes to the factor of hths?some advice?on how to scegliereun good product for diesel very pumped??

[V.V.]

Regarding the shear resistance on a given surface and a given thickness, molecular; we can say that under a value, which conventionally ? was fixed at 3.5 HTHS by the manufacturers, the oil complies with the specifications the so-called "Energy Saving" but said in a nutshell, the film of lubricant below such a value is considered to be weak. You also have to keep in mind that the shear strength of the layer to polarized also depends on the condition of the oil, and that the reference values are detected at 150? on the lubricant tend to be new. Each lubricant has capacity?, who is pi? less detergents, accordingly, with the use that is made of the same detergents, leads to a saturation of the lubricant which also has the ability? dispersants, or properties? that allow the product to keep in suspension the materials of wear (metal dust, oil residue burned, etc.etc.). How much more? the oil will be? then saturated as the value of HTHS the tender? to fall and stabilize at a certain threshold.

For completeness, I report to you a Link that is part of my study documentation:

http://www.hddeo*****/hthsarticle.html

Consider that from that encountered by the old colleagues, the values of HTHS is too high can also generate a content SAPS rather high, with the resulting deposits deleterious to segments, and exhaust systems type DPF, FAP, Catalysts and the like, as well as? for other components of the engine, while the levels of cenerei sulphated too low can ruin the valves and related. Personally, I prefer a tenor of Ash to the medium-high with a value of HTHS the middle, approximating the frequency of replacement, opt-out systems, anti-pollution.

V. V. I would like to take,if you give it to me,of your great knowledge on the world of lubricants to ask you for info specific to a project that st? bringing forward for several years now but it's not? if I can express everything here,not to go off topic, or open a thread specific...I could also contact you in pm but I'm not going to not share your immense knowledge with no one, and then I would prefer to discuss it publicly in such a way that anyone ? interested to learn more can benefit.....now I ask you how and where to write this new thread where I hope I enlighten to our admin then we update...ok?

[V.V.]

For me there are no problems, the important ? in the case of projects type Nebrok 0W100 :
