[This review was collected as part of a promotion.] I have always changed my oil myself, it connects you to your vehicle. I've never had a new vehicle, only used cars with high mileage. I've used different brands, and different types, of oil-specifically for high mileage-when I used Pennzoil for the 1st time, it seemed like the car was more calm. Like a person, the car seemed to be thankful and ran smoother. After that, I never tried any other brand.

I have been using Penzoil High Milage in my 2004 Ford F-150 ever since I bought it used with 198,000 miles. I am up to 229,000 miles now. I have not experienced any lubrication issues and will continue to use this product until she gives up the ghost.

I have been a fan of Pennzoil for most of my driving life. I have a 2009 Honda Element. I used Pennzoil conventional oil up until I hit 75,000 miles. Once I hit 75k miles, I immediately switched over to PHM oil. I now have 307,268 miles. I have never used any other oil. At 305,000 miles, I had to replace the VTEC controller and my valve cover gasket. Not only was the mechanic impressed with the mileage, but how clean the vales and top end were when he removed the valve cover to replace the gasket. I change my oil religiously on time with nothing but PHM. This vehicle has never known any other oil but Pennzoil. Thank you, Pennzoil! BTW, I currently have 307,268 miles and still running strong.

[This review was collected as part of a promotion.] I First used Pennzoil in my first truck, I now have a third and all still run great. I have torn two of them apart and neither have had oil problems ( even if I got lazy with the oil changes). I am a customer for life.

[This review was collected as part of a promotion.] I used Pennzoil when I bought a 1974 VW Beetle...so I kept using it on my 1994 Pontiac Grand Prix...now my son NEW car...Pennzoil keep it running all these years...who knows if my youngest son would also used it in a bear future...

I run the high mileage formula in all my vehicles, since I have no idea what under 150,000 miles is like.. but I have never had a single oil related damage or issues, in the 8+ years i have been using it. and I must admit I occasionally go further than the recommended change mileage.

[This review was collected as part of a promotion.] I use the high mileage in my 72' pick-up.Could not tell you how many miles are on the truck but it runs like a new one with the high mileage PENNZOIL it does not rattle or squeak like it did before the PENNZOIL

[This review was collected as part of a promotion.] I've always been told to get Pennzoil for all my cars. High mileage works the best for me considering I drive 44 miles one way and have for over 20 yrs. Never a problem... you just stay loyal to some thing that's works.

[This review was collected as part of a promotion.] I use this product in my 2000 ford expedition with 200k miles I always change the oil by myself and my engine is in perfect condition and running strong because this product has served my propose on my engine.

[This review was collected as part of a promotion.] My grandpa has always used pennzoil he's finally made me switch sides. I've put it in my last 4 cars and never had a problem. Always changed around 4,000 miles. And looks almost as good as it did when I put it in
