...basically, "thinner" is better for FE, which gives the edge to synthetics, because their viscosity *stays* more consistant over age and load than dyno-juice does.

...however, dyno-juice *is* less costly, by far. However, more and more of the manufacturers are switching to synthetics for both engine and transmissions.
