even if it's top tear we highly recommend Octane booster every 1500miles, those cars tuned in Germany the premium there 98 octane, use German certified octane booster from MotorPower care

European octane rating is based strictly on the “research” octane. Gas in the US octane rating is based on the “research” and the “motor” octane. That is, US gas octane is based on the average of the 2 ratings. US 93 octane is about 100 octane for Europe’s gas. Stick with premium gas from a station listed in the top tier gas website. I use Shell 93 exclusively. You don’t need an octane booster. The engine computer (DME in BMWspeak) adjusts ignition timing based primarily on octane. How? The engine has knock sensors.

marcozandrini, in this case then for our race cars in Europe that they using 100 octane we should use the U.S. gasoline !!! there is a big argument about it but we talk whats happening in the market, such as the issues that we have here in the market much as carbon issue, the carbon build up issue percentage that we have it in the U.S. market vehicles is way higher than in Germany, I agree with u that the vehicle will adjust it self (nock & MAP) but it still not as you tune the ECU directly. we have many BMW repair shops and we get the feedback from them, who uses the octane booster more frequently in there BMW's, Mini's, Audi's & VW's they have less carbon issues and better fuel consumption.

Europe’s 100 octane gas is equivalent to our 93 octane gas because Europe uses only the gas’s research octane rating. Buy your gas from a station that sells top tier gas and additives are unnecessary.

I pulled the fuel injectors on my old E46 with the M54B30 engine. I thought that one of the injector o-rings was leaking. The business end of all injectors was pristine. I bought only Shell or Texaco fuel for that car. Both sell top tier gas.

This is all true for those of you east of the Rockies. For those of us west of the Rockies, we are stuck with 91 octane "premium".

aside from @marcozandrini's comments, you provide zero empirical evidence of your claims for your products. In fact, some of your statements just make me scratch my head. First, you are claiming that higher octane using your octane booster somehow reduces carbon issues like carbon build up. That is simply false. Second, your products lack serious tech data sheets that justify claims like "up to" 6 RON points per 20gallons with a note specifying "ideally suited for low quality fuel". Last I checked US premium and top tier gas is not low quality fuel. Even if we take your claim that your product boosts RON by up to 6 points per 20 gallons, that would only increase US 91 to 91.6 (1 octane point = 1/10th octane number). Now, since 6 points is your max claim, based on low quality fuel, we can safely assume that there would be diminishing values with high quality fuel. So even if we give you 1 point, that would make US 91 at 91.1...I'm being very generous. So, tell me how your $22/can octane booster is really going to do anything more than empty my wallet by $22 every gas refill.

Last, more importantly, i believe every german car maker from Porsche to BMW have all stated that even using lower-octane fuel does not harm their engines, despite putting recommended octane on the fuel cap/door.

first I'm not here to provide false info as you stating and not here to convince people like you they have info in there head and they think it's right. second yes better combustion less carbon in the system, to help u understand this one check the exhaust on cars they use low fuel and others high octane as race cars and you see the exhaust clean and not black from carbon fumes, third we state it adds 6 points to 20 gallons but if u mix it with less than 20 gallons u gain more points, also we are stating that it adds 6 points of RON because we know it's very good percentage and no other competitor gets to certify exactly how much there product can add, as well the formula that you provided is not right google it and check how many RON points will = AKI that they use in the US gas stations it's less but not as u starting 10th of the point, and as price wise our octane booster not $22 it's $17.99.
and about the low fuel quality will not harm the engine, there is a reason why they say that so don't follow the marketing check the issues that we have in the market that it's caused by the low fuel quality.

you have to try it to believe it...

sorry, you are flat out wrong wrong wrong on every count. Also, each point is in fact only 1/10th, and that is not at the pump in the US. So, it would be even less than 1/10th. no matter if we give your product wide lattitude in your unverified, no tech data or spec sheet, product claim, you would see less than 1/10th if any octane increase on a typcial fill up. And you misquote your own can, it doesn't add 6 points, it claims to add "up to" 6 points based on low quality fuel, whatever that means. Yes, you are selling at $17.99 although your site retails the product for $22. So, it is in fact $22 retail as you specify on your website.

I'll let you google search, but you can easily see from Porsche, BMW, and the like spokesman all have publicly stated lower octane fuel will not harm their engines, despite what is on the fuel cap/door. PERIOD.

Your view on the marketing is backward. They market higher octane, not the other way around.

I concur on that one Doctor !

I have found it is more a performance issue, on my 128, it states MINIMUM 89, I have used all shades from 87 to 93, I find on the 87 no problems except when I try some spirited driving 93 makes the whole feel of the car different (as in better different) placebo ? don't think so

but yes I did a lot of research and asked the same questions, the minimum WILL not damage your engine, it's just not recommended

what is MORE of a show stopper is the quality i.e toptier gas

I think on another thread which was hammered to death,

Your BMW will change the timing (etc) if you don't use the right octane, using an octane value higher than is needed, is not dangerous but wasteful
if your car says xx, use it, if it says minimum xx, do that, if it says 87 and you use 93 +octane booster you are burning your dollar bills for no good reason
