Shell Rotella 15/40 in the dinosaurs and Mobil 1 5/30 in the newer one.

Unfortunately the new diesel oils are putting less zinc in the mix. Not good news for the older cars.

I use Pennzoil 10W-30. The original owner of my Vette used it and I stayed with it.

I'd been using Mobil 10W-30, but after reading about Rotella, that's what I'll be running this Spring, Summer and Fall.

I have read posts here from 2 different people that started using regular Valvoline and now have switched to Valvoline Extended mileage, which basically is oil for a worn out engine. Do you think if they started with better oil, they may not have switched to the extended mileage Valvoline?

My wife's Camry, which had Pennzoil since new so I stuck with it when we bought the car, started the blue smoke start up around 65k. Went to Maxlife with it an got the same results as the Vette. I think I'll stay with Valvoline. To bad all engines have to wear.......

Perhaps. I can't claim Pennzoil is the best for all. I've owned my car for almost 12 years. No blue smoke. It's 27 years old, original engine, and about 154 thousand miles on it and runs great to this day. I never fix what "ain't broke".

What are you going to do in a few thousand miles when you run out of oil?
