[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!

[This review was collected as part of a promotion.] My 1999 Jeep Cherokee 4x4 has 260,000 miles and continues to run great with this oil. I think since my husband changes the oil regularly that Pennzoil High Mileage Oil will keep it running indefinitely.

[This review was collected as part of a promotion.] Been using this on my old truck for a long time, it still comes out cleaner than any other oil I've used after running through the motor for 3k miles. take my advice, you won't go wrong with this oil!

[This review was collected as part of a promotion.] I just started using this stuff for my 5.4 triton in my Ford. Before this I had a weird knocking noise I think from the hydraulic lifters. After switching the noise is either a)gone or b)so quiet im not worried about it. Great stuff.

[This review was collected as part of a promotion.] We own four very high mileage used cars because three of us travel an hour to work. My Grandson, Junior Ankiewicz, who does dirt track racing, told me to use Penzoil high mileage oil. Smart Boy! Keeps the old cars running!

2 years ago I switched motor oils to Pennzoil high mileage. The other high mileage oil I was using left a lot of sludge throughout my engine. Also seemed like it burnt quicker between oil changes. But after switching I no longer have sludge and my oil looks like it should at 3000 miles. Thank you for a great product!!!

I have a 2002 Hyundai Sonata for a daily beater and the fact that this thing still runs is nothing short of a miracle. The original engine blew up at 100k miles, and was swapped with one with 80k miles. it currently has 215k on it using only Pennzoil high mileage. No ticking, no chatter, and is being cared for regularly like the last one. The fact this inferior car still runs is nothing short of a miracle, and I have an idea switching from an inferior oil to high mileage Pennzoil has done its part to keep key components lubricated and healthy.

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.

[This review was collected as part of a promotion.] I have used this oil when I rebuild engines and the engines just keep on going. I have a few that are over 250k miles on them and they are still reliable and not burning any engine oil at all. I will continue to use this oil!

[This review was collected as part of a promotion.] As a single woman, anything that keeps me away from the garage except racing is a good thing. This oil helps me to stretch my visits to the mechanic out and save time for pedicures and shopping and NASCAR races!
