best primary oil for 20b running premix
 

Hi everybody!

I am running premix in my 20b thus no need to inject primary oil into combusion, that is the best primary oil for my application?
I can get TRD 10w40 here locally or import from USA.
I guess it could be any good syntetics oil for pistons engines like mobil1 5w50?

please advice!
thanks

Moscow? Cool!! I ran Castrol Syntec (20W-50) in my 13B turbo. Never had any problems. An added benefit of synthetics is that their heat transfer properties are generally superior to mineral oils, so you oil temps should be slightly better. Really, any quality oil (mineral or synthetic) will do...Remember, its much more important to regularly change the oil then which specific brand your using. I've used Mobil 1 in piston and rotary engines in the past and have been pleased with it.

yeah but castrol syntec isnt really synthetic, which is why they dont call it synthetic anywhere on the bottle. Its just good quality mineral oil, syntec is just a marketing thing.
