Best 2 litre oil 30wt, multi, syn ? Options

[rush]

I have always used 30 weight in air motors. Couple of 912 friends use syn multi...any thoughts

VR1 is a great oil, but it is a non-detergent racing oil that is meant to be changed after a race weekend (or two depending on the engine), hence there is little need for the oil to contain any detergents.

Something to think about if you expect to maintain a normal oil change time interval while running it.

BTW, we run Brad Penn 40wt in our Cosworth BDA race engine both out of experience and from the recommendation of the engine builder. Not knocking the oil that Jake developed one bit, because it's great stuff, but if Brad Penn is good enough for a 10,000 RPM race motor, it's probably just fine for our type 4's.

Valvoline makes two types of VR-1. The type you're referring to is a HD non-synthetic blend and recommended for street vehicles.


The other VR-1 is a full synthetic oil. It has about the same percentage of zinc and phosphorous, but supposedly for off-road use. They recommended change intervals at 500 mi. (Reason - lack of detergents).


Valvoline's advertising leaves much to be desired as to the difference between the two.
