What is Mobil 1™ Advanced Fuel Economy?

Mobil 1™ Advanced Fuel Economy oils are fully synthetic motor oils engineered to deliver outstanding engine protection and fuel economy benefits. The low‐viscosity, advanced full synthetic formulation can help to increase engine efficiency and improve fuel economy versus higher viscosity oils. Mobil 1 Advanced Fuel Economy oils outperform conventional oils and meet or exceed the latest industry standards.

What viscosities of Mobil 1™ Advanced Fuel Economy are available, and can I use them in my vehicle?

Mobil 1 Advanced Fuel Economy is available in 0W‐16, 0W‐20 and 0W‐30 formulations. Mobil 1™ 0W‐16 Advanced Fuel Economy is recommended by ExxonMobil for select Honda and Toyota engines requiring a 0W‐16 viscosity oil. ExxonMobil recommends Mobil 1™ 0W‐20 Advanced Fuel Economy for 0W‐20 and 5W‐20 applications and Mobil 1™ 0W‐30 Advanced Fuel Economy for 0W‐30, 5W‐30 and 10W‐30 applications. In addition, low viscosity oils are available in the high mileage, extended drain and truck & SUV product lines. Use our comparison chart, and filter by viscosity for the full listing.

Why should I consider using Mobil 1™ Advanced Fuel Economy?

Mobil 1™ 0W‐20 Advanced Fuel Economy and Mobil 1™ 0W‐30 Advanced Fuel Economy flow faster than 5W‐20 and 5W‐30 motor oils, respectively, reaching your engine's vital parts faster during startup. Not only does this help reduce wear on engine parts but it also reduces the demands on your starter and battery. Mobil 1™ 0W‐20 and Mobil 1™ 0W‐30 are certified as "Resource Conserving" by both the International Lubricant Standardization and Approval Committee (ILSAC) and the American Petroleum Institute (API).

Rated 5 out of 5 by elpcmaster from Peace of mind Good oil for your older car. I have a 74 Vettte and 93 Silverado that is now using this oil. Might not really need it but it just makes me feel a little better.

Rated 5 out of 5 by Saul from Solid oil One of the only 10w-30 full synthetic high zinc oils on the market that is made for a gas engine, and that has the perfect level of zinc and phosphorus for normal flat-tappet engines. Have used it in my oldsmobile 307 and jeep 4.0. Only thing is I wish it came in a 5 qrt jug.

Rated 2 out of 5 by Bobby from Valve noise I was excited to see this. Mobil one fan for over 25 years. I used to have it in everything. Lawnmower, tractors go cart and registered vehicles too. Thought this would be a great choice for both my daily drivers. Put it in my jeep 4.0. It has new livers and cam with chain. Having only about 8k miles since I did that work. Motor has never been this noisy. You can hear the lifter and valvetrain noise while driving it with the doors off.the bottom end is slightly more noisy than it was. Not ok noxious but concerning. When a half new motor with 230k on the bottom end that was strong and quiet sounds like a junk yard core from good oil I'm really disappointed
