Originally developed by the Mobil oil company, it is now globally marketed and sold by ExxonMobil. With the exception of the Mazda rotary engine , Mobil 1 will not void new‐car warranties where an American Petroleum Institute certified oil is recommended. Mobil 1 meets or exceeds API and International Lubricant Standardization and Approval Committee motor oil service requirements of all new‐car manufacturers, both import and domestic. If in doubt, always check your vehicle owner’s manual or contact the vehicle manufacturer. If your car manufacturer recommends a SAE 5W‐30 ILSAC oil, we recommend either Mobil 1™ 5W‐30 or Mobil 1 Advanced Fuel Economy 0W‐30. Mobil 1 Advanced Fuel Economy 0W‐30 will not void new‐car warranties where an SAE 5W‐30 oil is recommended.
For more than forty years, Mobil 1™ has been a trusted name in lubrication technology. Mobil 1™ also boasts an impressive track record with NASCAR and Formula 1 racing, and has endured testing in Castrol GTX the most extreme real-world conditions. Mobil Delvac™ 1300 Super 10W-30 and 15W-40 are advanced diesel engine oils that help extend engine life, allowing you to run your business with confidence.
More than the brand, the motor oil’s viscosity grade is of greater importance when choosing between Amsoil and Mobil 1 products. In essence, both offer the most common oil grades from 0W20 to 20W-50. Depending on the type of oil blend recommended for your vehicle, some variants may only be available through one of these two brands.
Mobil 1™ 5W-30 synthetic oil meets or exceeds ACEA A1/B1, A5/B5, API SN, SM, SL, SJ, SN PLUS, SN PLUS RESOURCE CONSERVING, ILSAC GF-5, Ford WSS-M2C946-A/B1. It also has General Motors Service Fill dexos 1™ Gen 2 and Honda/Acura HTO-06 approvals. Mobil 1™ 5W-30 is also recommended for General Motors 4718M, 6094M mobil 1 full synthetic and Ford WSS-M2C929-A applications. So, when automakers design their engines, they take into account the level of viscosity that will work the best. And they make that recommendation to vehicle owners in the owner’s manual. The recommendations found in the manual will look something like “5W-20” or “5W-30”.
Both Amsoil and Mobil 1 have a wide array of oil types, most of which are currently full synthetic and synthetic blends. While each type contains its share of special additives and conditioners, you must check the compatibility of these ingredients with your vehicle. As high-quality as these oil blends are, using the wrong type for your wheeler may lead to catastrophic results. At the very least, it could speed up engine wear and tear. There are many different grades of motor oils offered by Mobil.
However, Amsoil beat Mobil to it by formulating the first API-certified fully synthetic SAE 10W-40 motor oil, which hit the shelves in 1972. If there was anything good from WWII, it was synthetic oil. Germans originally pioneered this technology during the 1940s amid all the grim and chaos. And when the war was over, this innovation made its way into aviation in the ‘60s, where synthetic esters became popular and were used in turbine engines. It was at this point that current big oil companies saw the potential for synthetic oils. Both of these synthetic oil does an excellent job in their respective field.
