I have been using Pennzoil High Mileage for my '97 Camry. She now have over 360,000 miles. I still get great gas mileage and the mechanics who change my oil say the engine is in great condition. Love this product!!

Always used in my '88 GMC Safari. Took me to 300,000 miles. Always had great lubricating properties. No build up. Engine tap stopped with this product.

[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.

I used to work in a car care center and the only oil that came in a constant color and viscosity was pennzoil. I have used this product in my cars for several years and wouldn't use anything else.

I was recommended yo use this on my prior car when I changed mechanics, and it made a noticable difference on how much car ran. I drove an older Taurus with 100K+ miles.

[This review was collected as part of a promotion.] My truck runs smoother since using this oil. Only 72k miles on engine but quieter running than conventional oil.

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.] I don't know what it is about this stuff but it works great in my truck with 240,000miles. I find it reasonably priced and can find it anywhere.
