I purchased my 2002 Silverado 4WD with 147,000 miles on it. My mechanic recommended Mobil One. Have used nothing but Mobil 1. I now have 254,000 miles on it. Engine runs as good or better than it did when I purchased it. Great product.

When i first bought my Grand Cherokee it would use almost a quart of oil between changes, been using Mobile One High Mileage and it uses no oil at all. Great start ups too in harsh Michigan winters.

[This review was collected as part of a promotion.] I’ve been using this product for as long as I could remember. I have never been disappointed with it. I use it in all my vehicles and I plan on continue using it. Always reliable.

I always use Mobil 1 oil. I wish Mobil continued making oil for lawn mowers. Mobil oil is the way to go.

I Deliver Pizza For a Living So My Car is Everything To Me. I Put Alot of Miles on it, It Has About 128,000 Miles. And I will Keep Using Mobil 1.
