Dont clean an AFM with brake cleaner, you can damage it. When was the last time your fuel filter was changed? How about the o2 sensors?

[1996 328ti]

No need for high octane gas and please don't type in all CAPS.

Any CEL's? Is your cold air intake sucking in nothing but hot air?

Hello,
What is your temp gauge reading? Does it go up to almost halfway in the first 5-10 Minutes of driving? If not, your thermostat needs changing. Easy job; If it is not working, you get exactly what you have described. Good luck...

why are you so angry? maybe its because your car is just getting old...how long since you had an oil change? check your tire pressure you might be running on really deflated tires.

[feelstyl]

tire pressure are 32 in rear and 29 in front and my oil change is every 4500 km !

i take care very much of my ti .. but GAS PROBLEME Consumption, ... ... someone really knows about theses problems ? thank you all !!!!!!!!!!!!

[dkerchner]

Why don't you ask what other peoples gas mileage is like? Everyone? I'm guessing I get somewhere around 300 miles to the tank. I get about 70-80 miles to the quarter tank. How big is the 318ti gas tank anyways? 15 gallon?

[feelstyl]

65 liters 65 $ to full
and yours ????????????????????everyone plz !
