GUYS,
Right now, at todays prices, it saves at most a penny per mile to run lower octane gas. How many miles must one go to pay for a new engine?

I think it is a fair question to ask, is it allright to use less than 93 octane if, perhaps, you stop for gas empty and the only thing available is 89 or 90, will it hurt the engine? But regular use to save a few bucks? Not in my baby.

I have two other Benz products. On occasion I have had to settle for 90 Octane(Caseys General store only sells the low grade) but topped off the tanks after a hundred miles or so with the good stuff. I may be nuts but have never had to replace an engine.

Clean fuel, clean filters and regular, timely oil changes. They run for ever.
