[This review was collected as part of a promotion.] I've used this for thirty years and have always had good results, and I run autos into the hundreds of thousand of miles, last one was 312,000 and still running fine .

[This review was collected as part of a promotion.] It works and that's what counts, Penzoil, for all my vehicles needs. Keeps everything running smoothly.

[This review was collected as part of a promotion.] I dont have the newest or best car, but my son only lets me put Penzoil oil in it. Thats what he has used for ever along with his brother and daddy.

I have been using this product since I purchased my Jeep in 2010 and I have had no problems at all. I will always use Pennzoil in my Jeep and any new vehicles I purchase from now on. Keep up the good work on your products.

[This review was collected as part of a promotion.] I always buy this product to keep my engines going it hasn't failed me yet so I will continue to buy and use Pennzoil as long as you keep making it.

[This review was collected as part of a promotion.] Live in Texas and weather conditions are like no other state. Boiling hot to crazy freezing there no oil like Texas gold Pennzoil. Texas approved.

Since I was sixteen and driving , My dad used Pennzoil and it has always protected our engines. Never used anything else. In our family Motor oil and Pennzoil mean the same.

I use Pennzol motor oil and have been very pleased. There are other oils I've used and liked but I'm a J.Logano fan so I sipport the sponsors that support my drivers - thank you

this is the only oil I use in my 1999 Lincoln Town Car. it has almost a hundred and sixty thousand miles on it and the engine runs like it is brand new.

I don't drive a nascar, but my little Honda Del Sol certainly runs like a nascar when I use Pennzoil! I won't allow anything else in my buggy. I swear by Pennzoil!!!
