Mobil 1 High Mileage 10W-40, 5-Quart is rated 5.0 out of 5 by 6.
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 i habe been using for last 15 years 1983 Toyota Land cruiser inline 6 cylinder solid adjustable lifter engine in block cam cast iron head and ,lower end / long block / NO aluminum or alloy internal Oil contact parts / with exception oil pump tube screen I mix this 10w40 mobile 1 with 20w50 or any thicker mobile 1 full synthetic product i can source at pep boys in summer temps / heat & just plain straight in winter , I have been a Toyota Certified master Tech. since 1995 and only run Mobile 1 Engine oils in every Toyota personal vehicle i have ever owned Fact: Today's Mobile 1 full synthetic oil in the 40 , & 50 weights are as thin viscosity as older 5w30 and 10w30's , so a 1-3 step up in weights on older 1970's & 1980's even early 1990's with high mileage is indeed a benefit and positive , fact; I recently sold my 1995 Toyota T-100 3.4 V , i bought new in Toyota collage , it had 697,362 original one owner miles / from me , all on Mobile 1 full synthetic , w/ regular 3000 mile change intervals I used only oem toyota factory oil filters of course , and uopgraded to a larger tundra 4.37 v8 oil filter around year 2001 / 390K miles for added + 3/4 qt capacity oil mobile I also only ever used Mobile 1 full synthetic ATF in the T-100 original engine and tarns / Never a mechanical problem !

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.
