[This review was collected as part of a promotion.] I use Pennzoil products In everything that I have my truck is a 99 z71 257808 Miles on it thank you pennzoil

Its what I run in my 98 and 2001 dodge 1500s change every 5,000 miles and dont use any in between the only thing I might switch to would be pennzoil high milage thank you

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.

[This review was collected as part of a promotion.] I used a competitors brand for years but changed to Pennzoil when I seen Arnold Palmer commercial...I have been pleased ever since the change

Me and my immediate family use pennzoil only and for many many years. 35+. It is absolutely fabulous for your vehicles. Number 1 for us. Keep up the good work

[This review was collected as part of a promotion.] This is a great product to use in any high mileage vehicle. I use this in all my high mileage vehicles.

At 5,000 miles oil is still yellow! Never a hiccup or concern with the motor on any of my vehicles (1968,1986,2001,2004). Good for any generation motor and make! I will never switch brands and I suggest it everywhere I go!

[This review was collected as part of a promotion.] Product has just the right formula made for older & high milage vehicles to make the perform properly & the best of all it is American made.

[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.
