10w40 due to the added heat in the Florida sun. Will be changing over to Mobile 1 synthetic for the Vette with the next change. I have been using PureOne or Puralator filters recently and they seem to be working OK. Still running Dino oil in the other car because it still leaks

Was using Mobil 1 0-W40. It's getting hard to find and the price has rocketed! Last time I went to Wmart, M1 5-W30 was in a 4Qt. jug for a little over $27. Valvoline Synth 5-W30 in a 5Qt. jug was $23. Guess which one I got..........

I've had many muscle cars and always used Castrol GTX 10W30. It works just fine in my 85 Vette. Do try to stay away from Fram filters as I read something about them now being made of far less superior materials than they used to be. That's all it took for me . Stick with the AC Delco filter.

Before my LT1 c4s unfortunate end... 
(wiping eyes), I ONLY used M1 5-30 as recommended here and by the shop that did some work on it for me. I had asked since it was 100 plus and 90 plus humidity in TX. They said NOPE- nothing else in this motor!

on finding whats on sale. Autozone usually runs a 10 dollar special on Castrol. No oil is going to make a hp increase. Any top brand oil is about as good as the other.
