WHat is the best oil???
Little off topic because I use mobil one in my TA. BUT I use dyno juice in my other cars. WHat is the best dyno juice. I lost a 5.0 to quaker state once (all the drains in the heads where filled with black carbon like crap and I changed oil every 2,000 miles) so switched to castrol. How does castrol 10-30 stack up?

I've heard Quaker State is known for buildups in the heads. When I use to use Dyno, I just went with Pennzoil or Castrol.

Never had any problem with valvoline or pennzoil. Have seen a friends engine that use quaker state when we tore it down it was caked with crud. That was 20 years ago I would have thought that quaker state would have improved by now. Synthetic is better though.
