I have been buy Pennziol for my race cars for over 20 years. Never had a problem

Use this for my car and wouldn't use anything else

I like it. It works. I never buy any thing else. Please recycle.

This is what my dad always used, so it's what I reach for. Time-tested, dad-approved.

I use Pennzoil exclusively in my vehicles. I've tried other oils long ago, but found Pennzoil performed better, with no to MAYBE a little sludge.
