I do a lot of oil changes myself, when I don't have time I have my mechanic do it for me. He recommended this oil for my car because it has a lot of miles. I am happy with it.

Have an older, '63 pickup that has seen her days. This has allowed me to wait for an up coming rebuild. She runs smoother and burns less oil. Great stuff.

I bought this for our vehicles to keep it well oiled and running well after it is past 10,000 miles so that we can continue to drive it until, hopefully, passit on to the next generation!

I have used this every time I have changed the oil in my truck for 4 years now my truck has over 210,000 miles and your oil lasts and makes my truck run great. And for that I thank you!

I use this oil all the time love it, And it dose a great job And even when I go to change it. It still look's great no brake down at all and even at start up's no noise's like other oil's do, Would recommend it to all.

[This review was collected as part of a promotion.] Have a 2001 Chev Suburban with 375,000 miles . Have been using the high mileage oil fo5 more than 5 years.

Tried the high mileage for my old pickup. Definitely noticed a difference. The engine ran smoother, a bit quieter, and I notice an improvement in throttle response. I would use this on all my high mileage vehicle.

i trust Pennzoil over almost anything I can think of. I just do not understand advertising the 20 weight oil for autos over 75,000 miles. With that much engine wear, I want something with a t least a 30 weight. I am not talking 10 W 30 either.

[This review was collected as part of a promotion.] I have used the high mileage oil in our Honda that has 200,000 miles for awhile. I feel like it has really enhanced this old Hondas staying power.

[This review was collected as part of a promotion.] I bought this a few weeks ago, excellent for the long commuter miles I put on my Toyota, reduced heat and werae and tear.
