Why would you need to boost octane rating
beyond 91ish?

Just was looking around and came across a few people who use an octane booster on their BMW's. Just curious to see who else uses it and if it is worth it. |

It will be cheaper to buy 91 than to buy a lower octane fuel and boost it with an additive.
There is no advantage whatsoever to using a higher octane than recommended by BMW, unless you have modified the engine to take advantage of that higher knock resistance (forced-induction, or a change in compression ratio).

I've used it once or twice, and it really makes no difference. Just use good gasoline and premium gas and you'll be fine.

I only use Top Tier Graded fuel in my X5. Here in Indiana the Premium at Conoco is 95 Octane.

I know the Octane rating in the states is different to here in Europe bit of a shame really as it is well known you guys draw the short straw when it comes to fuel quality.
How ever all the majors have a Octane booster in their addidtive take BP Ultimate or Shell V power. So in turn yes it must do some good. Had a meeting with one of the managers from a refinery here in the UK today and he was telling me that they have almost refined all the sulphur out of petrol now in Europe. |

I would never put octane boost into any BMW, they strongly recommend against it...you are looking for serious problems, like trying to load Mac software into a windows based PC. my $.02

How about using a fuel system cleaner? Its a little off the topic, but would that make any difference?
