There's something about going back to the classics. All these companies and bargain brands you try, you never know what's gonna happen to your engine. Penzoil is the brand everyone knows, trusts, and no matter where you are you know you can always ask for it and they'll have it.

[This review was collected as part of a promotion.] I used the 10W 30 in my auto with wonderful results. Sold the vehicle with 366 thousand and still running strong when I saw my old car years later with 422 thousand on it then. Change you're oil and good things happen.

[This review was collected as part of a promotion.] My father only uses pennzoil and it is all I have ever used. My truck Has 200,000 miles and the engine still runs like new. The truck maybe rusting and falling apart but my engine still has its power and punch.

As of today I have 189563 miles on this truck, I have not had any oil related problems, and never have to add oil between changes. I may switch to high mileage pennzoil, when I reach 250000. Thanks for making a great product.

And I wanna take this chance to THANK EVERYONE AT PENNZOIL for all your hard work and AWESOME PRODUCTS. And may you all have a very MERRY CHRISTMAS and GOD BLESS YOU ALL!!!

I have used Penzoil all my life in every vehicle I have owned my family has used it for three generations in everything from our race cars to lawnmowers and it absolutely works the best I have tried other oils and have had part and engine failures but have never had a part or engine fail using Penzoil products they perform under the most extreme and rigorous conditions and will always use and recommend Penzoil products for generations to come. Thank you for making outstanding products David Tidmore

I am in the auto parts industry and sell a lot of different motor oil. Options for oil are crazy, there are so many different brands out there! Well the choice for me was easy, because I've seen the Pennzoil name for a long time as a big fan of Steve Park, and now Joey Logano, I support the sponsors, and have not been disappointed yet! Only oil I put in my vehicles! Only oil I recommend!

[This review was collected as part of a promotion.] I use this oil in my 97 5.9 Dakota since it was rebuilt by me. I have 247k on the truck that was mostly done by a 5.2 motor that at one time had nitrous on it. It still runs and I still have it. I got the truck at around 100 miles and it was abused and nasty on the inside with no air cleaner or pcv valve. This oil cleaned it up considerabley after 3 oil changes and correcting the filters. I have always used pennzoil in all of my vehicles over the year's and have had no failures.

My husband does all our oil changes...only product he'll use. His work car is a Subaru with 368k miles on it...runs like a dream! When other brands are on sale and I want him to save a few $? Nope! Tried and true...not taking a chance with another brand. Thanks for a great product.
