I am pretty new to this "Ultimate Diving Machine" experience. I want to treat my car right, but I also don't want to throw money out the window when I don't need to. My previous cars have never required premium gasoline, but they have never been BMW's either. I read in the manul to use 91 octane or above to avoid knocking in the engine. But I have also heard reports that unless you are driving a super high performance vehicle that your car won't know the difference between 87, 89, or 93 octance gasoline. I have a 2003 330 CI, It is the most high performance vehicle i have ever owned, but i don't know if it qualifies as needing the higher octane gas...and with the gas prices today, if it doesn't need it, I could save $5-$10 a week by getting the lower gas. What does everyone think? Has anyone had experience with knocking in their engine from lower octane gas?

Read this link here on the forum, I didn't write it but its the best article I have read on gas.

http://www.bmw-forums.com/forum/inde...howtopic=35034

You can use lower octane gas, the important thing is how "clean" it is and the proper additives. There was another popular article floating around written by an executive in one of the large companies (now retired) and basically he said the same thing, you can use lower octane gas with about a 5% loss in performance that he says most people will never notice.

The other scenario is to shark you car to get performance out of the high test gas (91+) you are using as this will give you better mileage as well as boost the HP (by around 9 HP or so) and remap your transmission.

Hi ! You must use minimum 91 oct for your Bimmer BTW your manual says so ! Do not lession to any crap about that it does not matter what grade ,that simply BS! , you want to use regular gasoline buy pontiac sunfire , chevy cavalier ,kia or other P of S !. Cars like BMW. Mercedes or Audi do not run on regular gas. In Europe there is not such a thing like 87 gasoline, minimum octane is 95 RON which is equal to 91 AKI - gasoline octane index for North American market. This 87 in US or Canada which would be in Europe 91 RON is simply a joke !!! I am wondering sometimes . you guys complain about- my car is only 3 or 4 years old . my car has only 50000 and my oxygen sensor has gone , check the engine light is on. my car accelerate poorly. my vanos unit broke down, my car run too hot ,etc.- WHY ? START WITH A GOOD GAS AND OIL FIRST !!!, and when you decide to buy a Bimmer treat it nice like a lady or buy GM . CHrysler or Ford and put into a tank Budwaiser, Coors Light or Miller - it will run ! Cheers !!!

Maybe if Zippy drank better fluids, his grammar and punctuation would improve.

But anyway, if it comes down to having higher octane gas in your precious BMW or putting food in the table, don't let a manual get in the way of your greater well-being. I am not aware of your financial situation, but I once struggled with just making ends meet and I had to come to terms with many undesirable compromises. There are many alternatives to purchasing high octane/nonane fuel, like additives that you can pick up for a couple bucks at your local Auto Zone.

Thanks everyone for the input. i am sticking with the higher octane, just wanted to ask and hear some opinions. It isn't a "making ends meet" issue, but if i was Frivolous with my money i never would have been able to buy the car in the first place. As it has been pointed out, saving a few bucks every week is not worth Jeopardizing performance and longevity. Thanks again...

Well, no, I don't have any concern for whether you know "more and better(???)" than me, but you've got an elitist mentality about your posts that I do not appreciate. If you're going to be an Elitist, then I think you would at least do so in a concise manner so that we can all understand/appreciate how great you and--as I'm guessing--your homeland are.

Ha ha Guys guys....Come on. Lets be nice and play together! Although it is entertaining, this is a big boys forum. The fact is manufactures do not get incentives from gas makers to put that in a owners manuals. My wife is an engineer at Exxon-Mobil and I have read their test results (because I was wondering the same). Fact is it all comes down to the way the car is designed and that is were the OM's come in at. Like porting for your fuel injectors for intance, more precise inquipment requires additives. If you buy a Ford focus, chances are you did so to save money, so why would you design it to run on premium? Its not an American vs Europe thing because Europeans actually feel better about our American cars than we do. I have tried Mid grade and can tell the differance in performance.

Oh and zippy, I lived in Europe for a while and the Mustang, Corvette, and trans am are like kings over there. Audi rules the audobon and Opel is in second (A general motors division).
