Best oil?

[Davey08]

20/50 Lucas high zinc with HP-3001 K&N filter, motor runs great. The oil is changed after 3 races. Never had an issues, when the motor is torn down it's very clean.

Mobil 1 synthetic after break in..Bearings look new after a season.. Seen it in 4 cyl and multiple V8 cars..Enought to make me trust their 15,000 mile stuff in my daily...For a low budget racer it works great.. This is short track dirt.. 20 lap mains.. Not alot of abuse...wet sump, solid head etc.

We use Valvoline VR1 20W50 and haven't had any issues in our 2.3. After breakdown, the engine is very clean.
