I have a 2002 Chevy Tahoe with 259,328 miles on it. It burned about a quart every 1,500 miles. Every since I switched to this high mileage oil I have not lost any oil in about a 3,000 mile period. I’m actually going to make it through a oil change interval without adding oil....

[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!

I've been using this in my truck ever since it hit 75,000 miles. Now, I'm pushing past 200,000 and it's still running like the day I bought it. I expect to get at least another 100,000 out of it, and I'm confident that Pennzoil High Mileage will get me there.

[This review was collected as part of a promotion.] I had, up until two days ago, accomplished my regular oil changes with Pennzoil products ever since my 2002 Honda was new! My little silver Civic took its last ride, and repair costs are such that a little over 220 thousand miles are all it will see with me. I had been using your High Mileage 5/20, but am planning to convert to your synthetic line for my new 2016 Mitsubishi Outlander Sport. I also trust your lineup in my '65 Chevy C10, 2007 Buell Ulysses and my lawn tractor. Thank you for carrying me down the road efficiently, economically and safely.

I found that using this oil in my 1997 Camaro works the best. I tried every other hi mileage motor oils and no other stacks up to this one! The whole engine runs very smooth and it really quieted my valve train down. This oil is best for my ride I wouldn't trust anything else.

[This review was collected as part of a promotion.] I have used the Pennzoil high mileage oil for quite sometime now. I ran it in my old GMC pickup truck which had well over 300K on it and it ran so smooth when I used this fine product of Pennzoil! I'm a believer!!!
