I saw some posts discussing the different types of fuel, but didn't see any mention of the gas with ethanol.
I am wondering if the 89 fuel (which is 10%ethanol) is ok for the '96 328is. The 87 and 91 appear to be ethanol free, never really paid any attention to it but I think that I should now. Which one should I use.
2. Should I do my first oil change at 3000 miles or wait until the oil service light gets closer. I don't think the previous owner used synthetic in it.
USE 91, and ONLY 91 IN YOUR CAR. THAT IS THE MINIMUM GRADE RECOMMENDED IF YOU WANT TO KEEP YOUR CAR.
as for oil change, 3000 if you love a clean, smooth, happy engine.
the light if you can afford not to care....
it depends on how you drive...i go by the color. when it turns anything other than carmel oil color, change it.
yah like el presidente said, you CAN run 87 in your car but it is best to run the highest grade in your car if you want it to last longer, which usually is 91 but some places you can find higher...and you can also wait for the oil change light to come on but changing the oil at 3k miles is not a bad idea

i have always heard that bmw's are made running on euro gasoline which is MUCH cleaner then our gas. because of this is why they BMW recommends using AT LEAST 91 because it is cleaner and it has the additives that are nessicary to keep the injectors as well as the fuel system clean and happy...in turn making you clean and happy.
while lower grade will run ok (like they just said), its not mainly the knock that one needs to worry about, its the injectors, fuel pump/filter, carbon deposits that build up due to dirty low grade gasoline, and stinky exhaust.
to me, clean engines are more important than a few bucks a week.
Most of us are stuck with 87, 89, and 91. As the others have said...89 is fine for your car...the power upgrade between 89 and 91 is negligable...if even present, but if you inject your car, make sure to use 91!
P.S. - If you switch to synthetic oil you really only need to do changes once every 5k.
