Hmm...after reading through 5 pages of debates back and forth between 87 and 93....would it hurt to just put 93 sometimes and 87/89???
Here in MA Mobile has 87 / 89 / 93 those are the standards for all the gas stations here except for like Shell and Sunoco which has 87 / 89 / 91 / 93 (more choices lol)
But when I first got my car the dealership filled up my tank and left the receipt in the car when i went to pick it up and i saw it [REGULAR] i was like wtf premium only!!! but it seems i was able to get better mpg with 87 than i did with 93??? can someone elaborate on this situation??
