				 |  What octane fuel is best for my car? I have a BONE STOCK 91 lx 5.0 vert and I went to fill up today. I decided to put in 91 octane rather than 87 and I noticed an immediate difference. The car started easier, idled smoother, and the throttle was more responsive.  What do you guys run in your stangs?  Also a gas related question. When I fill my tank up, my gas gauge needle goes above full. Being nervous about running out of gas, I have been filling up at a quarter of a tank. Is this a normal thing for the gas gauge to do, and is it still accurate?
