[This review was collected as part of a promotion.] Ever since I started using it in my truck, the truck has performed better and it seems to last longer than other oils I've run in it. Used to just run around the Air Force Base, and now living in Florida, it still seems to out last others.

[This review was collected as part of a promotion.] I have a vehicle that went over 300,000 miles on conventional 10W40 Pennzoil before needing internal repair (not lubrication related). The crankshaft measured out at near perfect factory dimensions, and there was virtually no internal dirtiness. Saw similar results to this in several other engines at tear down after anywhere from 100,000 to over 400,000. No other oil has proven as reliable.

[This review was collected as part of a promotion.] I've been driving, boating and riding motorcycles all my life, I've done all my own maintenance and oil changes. I started changing the oil in my mothers car when I was 13. I'm now 59, and all these years it was Pennzoil that I used, still do, always will.

I just got my first car and my dad told me "I told your brother and sister what i'am about to tell you, you ONLY use Pennzoil for your car" he says he believe it's the only brand that will work is Pennzoil I've never seen him use anything eels our garage is has all Pennzoil bottles! and I believe him because it's the only thing I use. I know my dad could give a more detailed review on your amazing product, but I'm hoping to surprise the family! Best product out there! My whole family is TEAM JOEY LOGANO

Over the last 30 years or so I have rebuilt or refreshed many automotive engines. I have noticed engines that have used Pennzoil exclusively have cleaner components without the sludge build up I've seen with other oil. These Pennzoil engines consistently showed less wear on bearings and piston skirts as compared with engines of equal mileage when compared with other brand oils.

[This review was collected as part of a promotion.] I have used it for 33 yrs in every vehicles and once the synhetic came out that's all we use!!!! I am a female love and a very avid fan of your product lea4bed how to change my oil at 15...stuck with what I know keeps my engine strong and quiet!!!!! Thank you for all the miles!!!

[This review was collected as part of a promotion.] I have always used Pennzoil in my cars. I have often seen other motor oils on sale for a cheaper price than what I pay for Pennzoil but I'll stick with Pennzoil because it may be cheaper but most likely the quality is cheaper too! Pennzoil is the best!

[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.

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.
