Yep had my R18 turbo d for 80,000 km would have done 20+ trackdays, used Nulon oil, never saw cloudy, infact oil often came out looking almost new after 5000km and a trackday,.probably had 15-20 oil changes. Car wasnt left sitting for.long

Had my 2.4 frank running for 25k now, only done 8 trackdays including 2 fulldays at both NSW and the world time attack, highest placed NA in clubspring, it gets driven once a fortnight now down the beach since i bought a jeep, Nulon e85 fuel stabilizer in the tank, again no issues.

Been running fuel stabilizers in my fishing boat for 3 years (1000cc 5ripple 2 stroke).

Just an amateur having fun. My R18 got 3 tunes for 98, caltex and United, K20 got tuned on United and my k20/24 has had the same treatment as my R18, has 2 united tunes for diff diameter and length intakes. United seems to work for me, Ive run expensive stuff a few times but i dont see its needed and i cant be arsed spending $4-8 / litre.
