Re: New Hemi owner
use only 89 and only buy gas from a TOP TIER station, not discount gas; 87 will work in a pinch, but the ignition timing is retarded to prevent knock under load, power output is reduced, and mpg is worse than 89, plus 87 does not contain the same additives that keep from forming carbon deposits in the engine.
