The latest Super Synthetic is slightly more accommodating for tomorrow’s cars than the Mobil1 0W-20 we are familiar with today. [fimg=left]http://www.cleanmpg.com/photos/data/501/Mobil_Super_Family_of_Motor_Oils.jpg[/fimg]Wayne Gerdes - CleanMPG - Feb. 26, 2011 The Mobil Super, Super High Mileage and Super Synthetic family. The Mobil Super Family of Motor Oils are formulated to help reduce wear, prevent sludge and extend engine life. Backed by the Mobil Super Engine Guarantee, the Mobil Super family of products is designed to help cars run longer and better. Mobil Super is already a successful brand marketed by ExxonMobil in Europe, Asia and Latin America, and it will now be available to drivers in the United States. The new line of automotive engine oils are appearing on retail shelves as I type. The Mobil Super family includes three products, allowing consumers to choose the right one for their particular needs: Mobil Super: A premium conventional motor oil that helps extend engine life by preventing sludge and reducing wear. Mobil Super is guaranteed to deliver proven protection for up to 5,000 miles between oil changes and features extra cleaning additives. It is available in 5W-20, 5W-30, 10W-30 and 10W-40 viscosities. Mobil Super High Mileage: Specifically designed to help extend engine life in higher-mileage vehicles, this motor oil combines sludge prevention and wear protection with anti-oxidants that help to reduce oil breakdown. Mobil Super High Mileage is also formulated with a seal conditioner to help prevent leaks and reduce oil consumption. It is available in 5W-20, 5W-30, 10W-30 and 10W-40 viscosities. Mobil Super Synthetic: A full synthetic motor oil that is proven to outperform Mobil-branded conventional and synthetic-blend motor oils to help extend engine life by delivering outstanding protection in high temperatures, along with the sludge prevention and wear protection properties. It is available in 0W-20, 5W-20, 5W-30 and 10W-30 viscosities. 0W-20 vs. 0W-20 While the entire Mobil Super family is interesting for any number of applications, what we are mainly interested in is the 0W-20 Viscosity offerings. And there are two. One from the latest release and the tried and true Mobil1 Advanced Fuel Economy Synthetic we have seen on retailer shelves…Every once in a great while What makes the Super Synthetic 0W-20 a more suitable choice is that it meets or exceeds the latest ILSAC GF-5 standard for today’s and tomorrow’s cars and trucks that are specified to use 5W-20 or 0W-20. The older formulation, Mobil 1 Advanced Formula 0W-20 while recommended for Ford, Honda, Toyota, Mazda, Mitsubishi and Chrysler vehicles, is only ILSAC GF-4 rated. Regarding the working side of the two 0W-20 formulations, The Advanced Fuel Economy does have a lower pour point then the Super Synthetic (- 53 degrees F vs. - 44 degrees F) while their kinematic viscosities (read FE enhancement capability) are only .1 Centistokes (cST) different at both 40 degrees C and 100 degrees C. That is indistinguishable where it counts. Meaning at the pump.
