This topic has been beat to death for many years on hundreds (yes, hundreds!) of forums. The general consensus is usually that people that are too cheap to use the recommended fuel should not have a bought a car that requires it...(yes, requires!) To some, change the way you think and stop whining when the LARGE majority of responders disagree with your thinking/action.
There is a limit to how much retarding the computer can do. Exceed that limit running crap fuel and you WILL damage your engine. The damage is not immediate...burning a hole through a piston takes time. Pinging can sometimes be heard and sometimes it can't. This depends on how well the engine noise is insulated from the cabin AND how sensitive the driver's hearing is. Why in the hell would BMW recommend/require/insist that owners use Premium fuel when Regular would be just fine? To some, that are on the fence between 2 or 3 different cars, the Premium requirement might be a deal breaker...costing BMW sales. Don't think for a minute that they don't know this. Pinging doesn't sound very violent but inside the engine it's quite a different story. Pinging(early detonation) is the fuel being ignited to early and the piston essentially runs into a wall of exploding fuel to reach the top of the compression stroke. This puts a huge strain on all kinds of engine parts...crank bearings, connecting rods, wrist pins, pistons(rings too), and the combustion chamber. The weakest point of these components is the face of the piston. That's what fails first. Stick with high octane fuel and do yourself and your car a favor. And by all means, don't be cheap. You're not "saving" anything. [IMG][/IMG] |

What about gas that contains 10% Ethanol?? Should we be avoiding these ethanol mixes? Where I live I can get 94 with 10% E or 91 with no ethanol.. Which should I be getting??

According to fuel-testers.com alcohol blend fuels, like E10, become contaminated by water dilution (phase separation) very quickly. When this occurs, gasoline octane of the fuel in the tank may drop as much as 3 points. By that math I would guess both are equivalent from an octane rating. It's getting harder and harder to find fuel without ethanol added. Given the choice I would run without.

PS: not even going to mention the evils of ethanol vs. HPFP problems from years ago.

Ethanol, on the other hand, does have severe disadvantages. One is that it sucks up water. Another is that it attacks gaskets, causing them to wear faster. |

The service manager at my dealer explicitly told me to only run a good brand of premium gas, preferably Chevron Supreme or Shell V Power. They have seen many cars with fuel injection issues caused by poor quality or low octane gas.

We're leasing the X1 and will continue to give back DI only motors after three years. Our previous N54 135i was badly in need of cleaning at 43k miles when we sold it and I'm sure the N55 in our X1 is heading there too. |
