Most modern automobile engines run with either 5W-20 or 5W-30 weight motor oil lubricating their internals. While these two oil viscosities have been shown to adequately protect an engine's moving parts, a lower-weight lubricant (0W-10, for example) could theoretically boost a vehicle's fuel economy rating. Therefore, engineers at Shell recently set out to formulate an ultra-low viscosity synthetic motor oil to show that this type of improved fuel economy isn't just theoretical. It's proven.
The collaboration between research teams at Shell and Gordon Murray Design led to the development of the fuel-saving 0W-10 synthetic motor oil. When tested in Gordon Murray's T.25 city car, Shell engineers discovered that the new engine oil increased fuel efficiency by 6.5 percent in city driving and 4.6 percent on the combined cycle.
Shell's findings don't imply that every vehicle would benefit from using this 0W-10 weight motor oil, and the company doesn't suggest that this concept lubricant would be approved for use in all modern autos, but it does show that an ultra-low viscosity oil can, when poured into the T.25 city car's sump, reduce fuel consumption. That's something, right?
