Can you put regular gas in a car requiring premium? well, here's the story. i'm getting a job soon to pay for a car cuz im getting my license in jan at earliest. anyways, i did some hunting around and found a nice Mitsubishi eclipse GT for 3,995. all was well till i saw it needed premium and with the amount gas costs these days.. i found an eclipse GS. the GS takes regular at the cost of a 50 hp less engine but strangely enough, it costs more than the GT like 1k more for like 8,000 miles less on the mileage. soo anyways.. can u do it? btw, im looking for a nice looking car that doesn't cost above 4.5k MAX( lower is always better) and has some decent miles on it. like not too bad. here is a link the the eclipse GT i want.
