which grade of gas do u use?

For US drivers, check out www.toptiergas.com

Personally, I use SuperUnleaded for both my BMWs because both are designed to use Premium Unleaded Fuel (91 Octane minimum for US)

I try to stick with Chevron, Unocal 76, and Shell.

Okay, I'm adding to this thread because I actually used Chevron for 3 tankfuls - now I know why people buy the usually more expensive Chevron - the first tankfull was around town and I noticed a quick response to the gas pedal - #2 took me from Idaho Falls to Laramie (western Rockies) and 20.2mpg - #3 took me from Laramie to eastern Colorado where I filled up on Shell, 22.7mpg - then the mixture of Chevron & Shell took me 540 miles to Kansas City, 22.6mpg - tomorrow I'm stopping at Autozone to see if I can find Techron additive since there are no Chevrons around here - will post further results after the next few tankfuls with additive

92 octane premium only...I paid $2.05 a gallon on Monday..I filled it up so high I thought my fuel gauge needle was stuck! It finally started going down yesterday though.

my needle on my 4.8 doesnt seem to get stuck, it likes to move fast for some dam reason

Probably that darned skinny pedal, I know that's what makes my fuel disappear...... but it's soooo fun!

I alway use 91 oct or above. Most times only can find 92 and was at $2.139 on Friday (19.555 gallons only cost $41.83).
