[This review was collected as part of a promotion.] This is our "go to" oil. I can't imagine using anything else.

[This review was collected as part of a promotion.] The only thing I use in my vehicles! Always have good results.

It's the only oil I use...why cause hubby says buy it cause it's better for ur engine. So I listen lol

I always use this in my car. I don't do it myself, but I make sure where I go only uses Pennzoil so I know that's what is in my car!

My dad would always buy this oil when changed our oil. Now that he passed we still use it till this day. Like they say daddy's are always right!!!

I have used Penzoil 5W-30 since I bought my first vehicle back in 1989! I am on my 3rd vehicle which I bought in 2004.
