I was actually just down at the Tractor Supply store Saturday, and happened to have a look at a jug of Rotella ELC, and according to the jug, their ELC is good for 300,000 miles without SCA additives, and 600,000 WITH SCA additives.
Of course, that would seem to assume use in a diesel engine.. I wonder if it lasts as long in a gas engine.
