I have used Pennzoil High Mileage oil in my vehicle for years. The product lasts a long time and seems to keep my engine of my vehicle running smoothly.

I have a 2001 Chevy Tahoe with a hundred eighty thousand miles on it. I've been using the Pennzoil mileage for about 3 years now and changing it every 4,000 miles or so, seems to be doing the trick the 5.3 liter v8 is purring like a kitten still.

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.

I've had a minor valve gasket leak for a few years and this high mileage oil has kept the leaking to a minimum while keeping the engine running as normal as could be expected.

I always run Pennzoil High Mileage in my truck. It helps keep my engine and seals in good shape so I can tow my R.V and Boat during the harsh summer months.

My mini van has 143,000 miles and my sedan has 110,000 miles. I use this in both and they run so much smoother than before we switched. I am so happy with this product.

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!

[This review was collected as part of a promotion.] I purchased this oil for the protection that it offers. Would you give your 4 wheel baby sub standard oil for lubricating its engine. I think not, that is why I only use the best.

I drive a 2002 Dodge Dakota and its got a lot of miles on it. When it comes time for an oil change, I know I can always trust Pennzoil High Mileage to keep my truck running great. It will never let me or my vehicle down.
