i was wondering about this and i may answer my own question. If you use fuel with a 10% oil content, will it get better mileage than one with 16%? knowing with the more oil you have to richen it up a bit. any ideas
maybe a little but not really noticable. if you want to increase fuel mileage then run the engine on the leaner side. no more then 270 and do not use a highflow airfilter (motorsavers (K&N not recommended any way)) keep the drive train smooth what are you running anyway
