With the worldwide push to go green, automakers across the globe have been wracking their brains trying to discover a new way to bolster vehicle performance while also improving fuel efficiency. To this end, a number of automakers have begun utilizing new engine oil in their automobile both to add more MPG to the cars and provide better protection from engine wear.

General Motors has introduced a new oil graded as Dexos 1 that it claims will help protect an engine from damages that could potentially void a powertrain warranty, while their Detroit rivals Chrysler and Ford Motors have enacted similar plots by utilizing SN and GF-5 graded oils respectively.

"GF-5 and Dexos1 oils have a more robust formulation that should give you better contributions to fuel economy, cleanliness and fuel emissions," Mark Ferner, the manager of the lubricants technology group at Shell, told AutoWeek.

Of course, switching to new oils can also help improve the performance of used cars as well, and can be an important part of maintenance for vehicles that have spent more time on the road.
