VR1 Engine oil is excellent.
I didn't hear thanks Brad Penn

In last season we used М3 and oil (15w-50) the engine dohs an injector. Valvoline we don't trust, at us on sale it is a lot of fake. We use Motul at the checked up dealers. There was new oil Bardahi that will tell who uses? Now there is time what to communicate and learn on more. Thanks for answers....

Whether it would be desirable to learn friends you use in alcohol motors what or additives or additives in oil.

Yes 85 perfectly works.
But it is not necessary to forget, and Hygroscopy at storage in a tank.

For an example in Russia the gallon of ethanol of 100 % costs 13.5$ it at the local dealer. The ofitsalnyj dealer sells on 17.5$
We very seriously concern it.

Prompt who uses additives in oil for the best work of the engine on NOS
Or is better it is not necessary to apply additives?
And as, what oils use? Also that you can tell about oil Bardahl

I apologize for my English.

The ethanol draws a moisture, don't leave gasoline on long in a tank.
