E36 M3 REQUIRES at least 91. Read your owner's manual. The difference between 87 and 91/93 is less than $5/tank.

If you run less than 91, your going to end up paying big time.

I'm sure in a regular 3 series you can get away with 87, my 325i requries 89, and my M3 requires 91 (and I wouldn't dream of giving it any less) a high compression engine that may or may not see 7k on the tach, ill pass on being cheep on the gas. Put 91 in your M

You forgot 93. I use 93 or Sunoco GT100 (98 AKI).

The highest I have in my area is 92 which is the V-Power from Shell, and I won't feed her anything less.

I put 93.

Just think about it: it does not make much sense to put lower grade fuel, especially now with rising fuel prices.

Why? Here is why.

People who can remember 10 years ago, when gas was:

- 87 $0.99,
- 89 $1.09,
- 91 $1.19.

So, 91 was 20% higher than 87.

But now, even if 87 let's say is $4.29, and 91 is $4.49, the difference is only 4.6%. And when you have to put 15 gallons in your tank, the difference of only $3 between 87 and 91 is not much.

With that said, BMW's can get worst MPG (not to mention loss in HP) going to lower octane. It will spray more fuel (so I read) of the lower octane fuel in an effort to help regulate engine temp and therefore your fuel economy goes down.

A word from the wise: just don't go lower than what is recommended in your owners manual. If you need to save the difference I won't say sell your car- just take the bus when you have the option too:yikes:
