I know my Mini runs better with off base Top Tier premium gas. I get better gas mileage, more power, and the engine idles better. The base gas sucks, my Jeep that normally could care less what gas I use knocks when I use it. Even with a full tank of gas you're only saving about $1.90 if the difference is 10 cents, don't tell me you can't afford that!
