As long as you use the weight and SAE grade motor oil recommended by the manufacturer of the car, there is no real difference among brands.





Consumer Reports tested motor oils by putting them in New York City taxis and checking the tolerances on wear surfaces before and after running them hard for many miles. There was no measurable difference in protection among all the oils tested.





This was not the most severe test, however, because the cars ran continuously, so there were no 'cold starts,' the toughest test your oil must face.





Full synthetic oil (Mobil One, Castrol Syntec, Penzoil Platinum, Valvoline MaxLife Full Synthetic, Quaker State Q Advanced Engine Full Synthetic, or Amzoil, etc.) protects better in this case. Because they have a wider viscosity index (thicken less with cold, thin less with heat) they are thinner after sitting while you work or sleep, so that the oil pump can get it to where it is needed to protect against wear quicker.





Synthetics also thin out less as your engine heats up, so they maintain the protective film better and under more severe conditions.





Finally, a synthetic oil's light fractions (thinner components) are less volatile, so they don't evaporate as readily, making the oil more stable and longer lasting.





I hope this helps. Good motoring!Which high quality motor oil brands (lubricants) to you know ???
I usually use Castrol or Valvoline
I have heard from many gear heads that Amsol makes the best overall oils/lubricants around. I also have seen lab reports agreeing with this.
Royal Purple for sure.
i use nothing but synthetics in my cars... the only one i've used is Royal Purple... its a raced developed oil that is definitely worth its weight in gold... i've also heard very good things about Mobil 1 and Amsoil... another oil to look for is Red Line Oil... good luck with what you choose...





from the US by the way...
I've used Vavoline 30 SAE in all my cars since the 70's. The exception to that rule...Using 10w-40 in my newer model cars.





Reason: When you do have to rebuild an engine. It's a nice way to eliminate 3-6 hours work. There is NO build up of sludge inside the engine with this oil.





I haven't ';had'; to rebuild one in years, other than my toys. And, they get dogged pretty hard. So they naturally need one from time to time.
