I was literally raised to use Pennzoil. My dad and uncles would always talk about fixing cars & they they never even said "motor oil" they always said "Pennzoil" and our garage always had the yellow quart bottles around. I still use Pennzoil it to this day & it's always worked well with my vehicles. The yellow bottle is Iconic! I miss seeing that Pennzoil logo on Michael Waltrips car growing up.

[This review was collected as part of a promotion.] I have been used Pennzoil for years now. I have been over on milage on my oil changes both my vechicals I have not had a problem at all with my 4.2 vortech in my 02 trailblazer or my 2.2 chevy Cavalier 1996 great engine oil y'all

I usually have my oil change at stores that carry Penzoil....because I have owned a lot of different cars, makes and models and they all ran with out major engine problems...yes I keep 'em well past 100k....I can only attribute it to regular oil changes with Pennzoil..

I've been using 5W-30 Pennzoil on my 2010 Nissan Titan Pro-4x since I bought it new. I change it every 7,500 miles, and have had no issues. I've sent used motor oil for analysis. The report shows everything is great with the oil. That I am replacing it at the right intervals, and there is nothing in the analysis to suggest something is wrong internally with the engine. My truck has 78,000 miles on it, and I haven't had any work done on the engine so far.

[This review was collected as part of a promotion.] I use Pennzoil active in just about all of my toys. Its hard to find a good convetinal motor oil anymore now that everything can run senthetic. I need the conventional oil to run in my 1972 Chevy c10. I also use it my 2 dirt bikes and all of our ATVs. Stuff is just perfect. You can't ask for better and the price is way less then it is worth. I really enjoy your product and so does the rest of my family!

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 use to use other brands of oil and when I became a Mechanic and started working on cars once I seen the different effects oils had on the inside of engines it made me a believer that depending on what brand oil you use has a lot to do with your engines life. I made the switch over 20 years ago and cant find one bad thing to say about Pennzoil. If you want to take care of your engine and extend your engines life span without spending a lot in repairs use Pennzoil I've seen inside of many engines and with Pennzoil it keeps the inside looking new.

[This review was collected as part of a promotion.] Every month or sooner my father gets a bottle of Pennzoil from Family Dollar for his truck, even uses it as wax for his trunk to wipe it off after he washes his truck and shines the tires with it too!

[This review was collected as part of a promotion.] I've been using Pennzoil since I got my first car at 16. I'm 67 now and still using it for all my oil changes. Always satisfied and engines are always clean . I have 165,000 on my GMC Denali and she's still running smooth.
