Rated 5 out of 5 by from 2007 Six Liter Chevy 2500 WT with a noisey lifter! January 30,2017 The truck started ticking off and on, about 5 or 6 months ago. When oil change time came I tried Mobil 1 High Mileage 10W-40 and three or four days latter the ticking was gone. Yea I would recommend Mobil 1 too a friend and a Mobil 1 Oil Filter. 2 great products from Exxon Mobil! PS The gas is pretty good too!

Rated 5 out of 5 by from best oil you can purchase I have a 1994 Jeep Grand Cherokee 5.2 ,now it has over 221,000 miles.I tow a 29 ft trailer for camping 4 to 5 times a year. I use high mileage10-40 and starting using this oil @ 75,000. Mobil 1 is the best. I change oil every 5-6 thousand miles. The jeep spends a lot of time in the forest exploring trails. Motor is still running strong, thanks for a great product. Joe, in Tuolumne county, Ca.

Rated 5 out of 5 by from My 2001 Durango 5.9L is purring like a kitten Hi, bought a 2001 Dodge Durango with a 5.9L Magnum V8 about a year ago. This engine is known for blowing up and for burning oil. I was using Valvoline conventional as I always had in the past, but she did not like it at all. She ran rough and was using a quart between changes (3000 miles). Switched to Mobil 1 HM 10W40 (went a little thicker since it gets super hot where I live) and immediately noticed how smooth and quiet she ran and she has not since used any oil. I have great peace of mind now with this oil in my engine and even my gas mileage has improved by one mile per gallon.
