Thread: 390 Oil...where is it going?

Tweet

Well great news today! Started it up and after warming up (180) it was around 20 psi at idle, wouldn't drop. It got hotter (190-200) and was at 15 psi. At the max heat I've had today (damn traffic) (215) it was still at 13 psi. Awesome...better than before. I'm looking to keep her running, so this pleases me...

Good news for sure! Personally, I wouldn't run a single weight oil! My current preference is a synthetic 10w-40.. just mho! 8-)
