Pennzoil has been the only oil I have ever used in my trucks, and our family cars for the past 58 years of driving. My second car was a 1962 Pontiac with 385,500 miles on it, and my 1995 F250 Ford that I drive now has, 288,950 and is still going strong! So thanks for making a very good product.

I have been using this product since I started driving 15 years ago. I always buy older cars, and do my own oil changes. It definitely has helped all of my vehicles run forever. I would say all the cars I've bought have hit 300k miles and they still ran awesome when I sold them. Great product! Will use this brand as long as I can drive!

Pennzoil High Mileage is the real deal, I used it on my past vehicle and when I sold it the truck had 300K miles on it, I told the past owners what oil I used and they said they would continue to use it also, two years later I still see my truck around town and still running, I know it's because I used Pennzoil High Mileage and changed my oil every time it was due!!

[This review was collected as part of a promotion.] I bought this for my 2006 Pontiac with 150,000 miles. I noticed that over other brands this one actually worked. I only had to add about 1/2 of a quart over 5000 miles instead of the usual full quart!

I've used this in every high mileage vehicle I've owned and the result was amazing. The vehicles seem to have more of that "purr" to it and ran smoother than ever. I've always supported pennzoil products and will continue to recommend it to family and friends.

[This review was collected as part of a promotion.] My car has over 170k miles and I'm cheap so I refuse to buy a new one until it kicks the old rust bucket. I've been using this oil for the past few years and will continue to use it until I have a car with low mileage. Vehicle has no noticeable engine/oil related problems so if it ain't broke, don't fix it.

I'm a mom of two kids who does her own oil changes and I have been useing Pennzoil high mileage oil for a while now because it never lets me down. I really enjoy driveing older cars and enjoy working on them myself so I need an oil that's geared to the needs of a car with 13+ years on it. My engines run smooth and strong no matter Michigan's whacky weather, thanks to Pennzoil high mileage oil!

I grew up with my Father using the Pennzoil brand oil as my Grandfather did for as far back as I can recall . I my self have been using Pennzoil High Mileage oil in my 2006 Town & Country since I got it back in 2012 and in other cars before . I have never had a complaint and the oil in my humble opinion in simply the best and ONLY brand I will ever use . My son is getting ready for his first car and will be following the family brand loyalty and using the same oil .

[This review was collected as part of a promotion.] I have 4 cars, and the newest one has 122,000 miles. Synthetic blends like this take some of the worry out of the longevity of my engines, and saves me the cost of more expensive full synthetic oils.

I bought this for my old high school ride a ponitac firebird witch I had kept in good condition, witch had 15000 miles on it and a oil changed it to this runs like brand new best oil for any car I have changed to and I plan to change my other cars to penzoil when the time comes
