- Does anyone know the price for the BMW valve?
- From now on, use only Octane 91 gas, which should reduce the risk of burned valves.
- Clean the injectors too.

Thanks! 91 only plus in my Bimmers. There are 4 in the house and its something i stress on. Its amazing when i pull up to a gas station and see someone with a brand new BMW pushing the 87 button. I just shake my head and laugh, but chances are they are returning it in 4 years anyway, and don't understand the fuel milage is decreased so much! lol.
"penny wise, pound foolish" i was taught.
Thanks all for all your help!!
