Keeps your engine running like new

Mobil 1 advanced full synthetic motor oils deliver exceptional performance and protection for vehicles of all ages and for all driving conditions – normal to extreme. 

Mobil 1 oils keep engines running like new by helping:

  • Combat sludge and deposit buildup 
  • Reduce wear
  • Control oil breakdown

Mobil 1 motor oils offer a full range of temperature protection: For cold starts, the oil keeps flowing as low as -40 degrees Fahrenheit, and it can withstand high temperatures of up to 500 degrees Fahrenheit.

In fact, Mobil 1 is the World’s Leading Synthetic motor oil brand, recommended by more car builders and used by more NASCAR® teams than any other brand of motor oil. What’s more, Mobil 1 oils meet or exceed the toughest standards of Japanese, European and U.S. car builders.

Please reference our Mobil 1™ Product Guide for a quick look at specifications including zinc and phosphorus, as well as manufacturer approvals for Mobil 1 motor oils.

Rated 5 out of 5 by from I use Mobil 1......Period....And Here's Why... I've had my 1998 Ford F150 with a 4.6L SOHC V-8 since new. I run only Mobil 1 5w30. Drove it 266,000 miles until it blew a head gasket. Where we tore it apart - absolutely NO WEAR - ZERO. Clean inside and no wear. Cylinder walls still had a crosshatch pattern. Crank and cam journals were void of wear and we went back with standard sized bearings. I can provide images of this engine when it was torn down. Mobil 1 for life.....FOR LIFE. Engine is now rebuilt and ready to go back in my truck. Had I taken better care of my cooling system it would never have blown the head gasket. It would have gone way beyond 300,000 miles WITHOUT A REBUILD on Mobil 1.

Rated 5 out of 5 by from Best Synthetic Oil Ever since a friend introduced me to extended wear oil products from Mobil 1 I've been loving only having to change my oil once per year. Be sure to check it once a month in case you have to top off if your engine burns a bit of the oil, but otherwise if you're under 15k miles per year on your car like I am, no need to change it 2-3 times a year, once will do. I've been using this oil for most of the 11 years that I've owned my 2003 Suburban (and my VW Jetta, Toyota Corolla, and Hyundai Elantra -- rest of the family). I have over 100k miles in all of my cars (almost 200k in a couple) and they all purr like kittens. Feel confident in using this oil once per year

Rated 5 out of 5 by from If you drive Suburban/Tahoe use it If you own a Suburban or Tahoe use Mobil 1 5W-30 solely and your engine can go over 300,000 miles. Now driving my 12th Suburban and the last 3 used only Mobil 1 and the first 2 went 340,000 and 350,000 miles respectively and the engines still ran like new! Have 125,000 on current Suburban and still does not burn any oil between changes - 7500 miles and the technician smiles because the old oil looks as clean as the new oil! - and runs as smooth as the day I drove it off the show room floor. Every GM dealer carries Mobil 1, use it and you will be amazed at the result.
