I've never like Pennzoil. I used it when I first started driving. Oil pressure would drop a lot when hot. Switched to Valvoline and was much better. That was 40 years ago though. lol Not sure about today.

Maybe Pennzoil had a lousy formula back in the seventies. BTW that Comet ended up going over 250,000 miles on its rebuilt engine. Would have gone further if the oil filter was tighten after an oil change.

If a 10W-40 conventional is what you would like to stick too.
Valvoline 10w40 Daily Protection is a bit thicker at 212 degrees then Castrol GTX 10w40 conv, however the GTX does have a bit more anti wear additives. Both are good conv oils..... Just keep the oil clean !!! |
