as an authorized workshop motul I can promote this brand eye, however, the viscosity does not indicate if an oil ? better than another you must always observe the gradation indicated by the manufacturer then a 0-30 not ? best of one 0-40 only because it costs more than' we also see the specifications required by the home itself, then the only thing you can change ? the brand of oil but specific and viscosity ? one

and go from a 0w40 to 5w40 pu? give problems? I speak of specifications for bmw 530d euro 4

Complies with the specifications and never have a problem, a piece of advice, never change the oil specifications!!!!

as specifications bardahl technos 5w40 ? better than bmw, change the colour, I have advised bardahl reassuring me that ? better

but the BMW should not use the 5-30 longlife or I am wrong?

my booklet shows 0w30 -- 0w40 and for refilling 5w40

mobil1 0w40

I confirm longlife 5-30!

but the 5w30 ? for the 2000d I have the 3000d

I knew that also goes on the 3000d! I used it on the x5!
