Well that depends on where you live. That ish adds up if you drive a lot like me! 2000 miles per month so far
Never had to use premium, never had a gas guzzler either though.
nope....mostly personal miles...don't ask lol****! You must of got compensated from work right? I do 2000 miles taking little man to grandparents house! Good thing I get good mpg! lol.
some cars yes, some no....my two Acura Legends are chipped with air/fuel curves adjusted. If I don't run premium, it will knock like crazy. My wife's supercharged Monte only runs 1-2lbs of boost at most on anything less than 93 and I like 10+psiThe "premium gas only" in most luxury and sport vehicle is one big hoax. Most modern engines with computer controlled advance knock sensors and engine management can easily run on regular unleaded. Sure you get slightly lower MPG and a few less HP. But it absolutely doesn't do irrepairable engine damage.
