[This review was collected as part of a promotion.] I use high mileage penzoil in all my cars. It has great performance, and is way ahead of its time. Its the best oil on the market to date.

Love the high mileage semi-synthetic for both my vehicles; A '96 Ford Ranger 170,000 2.3L and '10 Ford Focus 2.0. Descent price for a great oil and hasn't let me down yet.

[This review was collected as part of a promotion.] Began using Pennzoil High Mileage oil in my 1988 S10 when it reached 145k now with 215k it's still running fine. Go Pennzoil.

[This review was collected as part of a promotion.] This oil works great for my car. I never worry my engine running well when I have this oil in the car.

[This review was collected as part of a promotion.] Only oil I will buy I've used every since high mileage came out my 05 Grand Cherokee has just under 200,000 and my oil comes out almost as clean as it was when I put it in.

I use this product in my 91 safari van as it has over 150 thousand miles and we drive a lot so I try to protect the engine as much as I can! Thank You Pennzoil!

[This review was collected as part of a promotion.] My Jeep Cherokee has 208,000 miles on it. I've used Pennzoil High Mileage for my last two oil changes. What a difference an oil makes. I recommend it to all my friends. Way to go, Pennzoil!!

[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.

[This review was collected as part of a promotion.] My 2001 Camry has valves tapping. I've been using the high mileage and I can tell it helps the valves.
