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 My engines are thoroughly clean inside Year after year and well into six-figure miles, Mobil 1 motor oil keeps the inside of my engines completely clean. I am confident that Mobil 1 will allow me to operate these same vehicles reliably for many years to come. As I write this review, we are forecast to have many more days in a row of 100 degrees or more, and I am confident that Mobil 1 will protect my engines through any and all hot spells. July 16, 2016
Rated 5 out of 5 by 360,000 mile Camry My 03 Camry with 2.4L topped 360000 miles this week engine gets the same milage as it did new. The car uses no oil between changes and when I replaced the cam cover gasket the engine was spotless inside. I have used the 5w-30 since the car reached 5000 miles. June 29, 2016
Rated 5 out of 5 by Most don't understand oil ratings No I don't work for Mobil or its affiliates, I was simply exhausted with scanning through the marketing materials presented by the majority of engine oil manufacturing. Therefore I learned what all those specifics mean related to engine lubricants mean and whittled them down to this one very simple equation: Pick the synthetic lubricant which has the lowest possible thickness at cold temperature rating (40 deg C) while also being able to maintain at least 10cSt thickness at operating temperature (100 deg C). Mobil 1 0W-40 was able to achieve all three of these requirements 1) Synthetic lubricant (uniform molecules which have been purified 2) Viscosity - Thickness at 40 deg C = 70.8 cSt 3) Viscosity - Thickness at 100 deg C = 12.9 cSt Therefore I was able to choose one single lubricant for all my passenger vehicles, which is available locally without special order. Those looking for a go-to standard engine oil would find Mobil 1, 0W-40 one of the best alternatives for meeting this requirement. I will modify this response, once I am able to perform lubricant analysis at my next oil change May 15, 2016
Rated 5 out of 5 by Works as advertised. I used Mobil 1 5w/30 for 12 years and 260,000 miles in my 04 GMC 2500HD. Changed the oil between 6500 and 7000 miles. The engine outlasted the rest of the truck. Enough said. June 25, 2016
Rated 4 out of 5 by Good oil but I have used non-FS Mobil 1 0w-40 before in a 2005 BMW 330ci, but this newer FS oil does not mention BMW approved, so why is that? May 2, 2016
Rated 2 out of 5 by New formula does not meet specifications. This has been the only oil I have used in my BMW's for years. Now, there is a new formulation out that does not currently meet the BMW LL-01 specification. Is this going to be addressed? Soon? BTW, what does 'FS' stand for? I (and many others..) have stood by this oil for years. I have nothing but good things to say about this oil but if it will not meet BMW specifications then I will be forced to switch oils. I truly hope that I don't have to do this. May 1, 2016
Rated 5 out of 5 by Great oil for the GM 3.6 Glad I could find a oil that meets GM spec. For the 3.6 They had timing chain stretch problems. The Mobil 1 does a fine job even in the Arizona heat. I worked at the GM desert Proving Grounds and saw first hand what Mobil 1 did in their test fleet. May 27, 2016
Rated 5 out of 5 by great engine longivity Been using Mobil 1 5W-30 in my 2000 Pontiac Montana, which I bought new, since about 30,000 miles and noticed the brown staining from conventional oil at the filler area. The car now has 340,000 and I still use the regular Mobil 1, not the high mileage, and still do not have to add any oil between changes at about 7,500 miles. I do the changes when the Pontiac oil change reminder comes on. When I change the oil, I look in the filler port and the engine is still clean and no sludge can be seen. Engine has never been apart except for the 3.4l intake manifold gasket failure, common on this engine I am highly satisfied with Mobil 1 and use it on my '84 Buick Riviera Convertable and '09 Chevy Avalanche May 16, 2016
