Both are turbo so the highest octane you can find. If you're trying to be cheap, don't do it or just buy a cheaper car.

I don't understand peoples reluctance to get premium gas. If you have a 12 gallon tank that is $2.4 more. Over 300000 miles that would roughly be $2500 savings. If you drive 13k a year that would take you 23 years to drive that much.

You got a performance car. Give it performance gas. Premium all the way. You also get better cleaners in premium.

Yes. Almost all turbo cars will require premium.

Yes, premium for both. They both are high performance engines with a manufacturers requirement of 91 octane.

I'm running 93, but the manual (p 164) recommends minimum 89.

Plenty of leased BMWs are getting 87 octane all day long. Miriam two offices down drives a BMW because it makes her feel important, not because it handles well. It'll work just fine for 36 months on 87. Reality of the brand outside of these forums...

Disclaimer: I don't know any Miriams... just saying.

Note than it states that the engine will knock at 89. It is not the minimum recommended. It clearly states that a minimum of 91 is recommended.

You will also get lower gas mileage on lower grade fuels.

Wow so many different octanes offered around the world. We get 91 as the lowest (optional ethanol blend of <10% i think) but the premiums are 95 low and 98 high. Shell used to offer 100, advertised as the fuel used in F1, but this was scrapped shortly after.

US, Canada and a few other countries use a different method to calculate octane. They use (R+M)/2 (aka as AKI).

In Europe, Aus/NZ and many other places, they just use R (aka RON). A RON of 91-92 corresponds to maybe an AKI of 87.

North America: 91 octane or ethanol-free gasoline?

In some countries, premium is at a higher octane than 91.

Here in Canada, some Petro Canada stations sell Ultra 94 with higher octane. (I have seen some forum posts on the Web claiming that BMW cars are not intended for use with such octane unless specially tuned. I have no idea if that is correct.)

Some articles about performance cars suggest using gasoline with no ethanol at all. But in North America nearly all gas has up to 10%; and BMW says that is ok. In Canada and in the USA, Shell sells a 91 octane gasoline V-Power Nitro+. In Canada, it contains zero ethanol but not sure that is the case in the USA.

I got the Dinan Tune Stage 1 installed and the specs they publish indicate the hp and torque with 93 octane gasoline. So, my M235i should work well with Ultra 94 gas. When I cannot find it, I look for a Shell station and then I use the (91 octane) Shell V-Power Nitro+. Is this based on proven facts? Not really.

For those of us in the states, buy gas from a station that sells gas that meets the Top Tier Gas standard. The standard was developed by BMW and other manufacturers.

I was able to find a station which has race gas not to far from me. I did not think it would make that much of a difference but boy was I wrong. The car was a beast! It pulled harder and could be placebo but even sounded meaner. It was 10 bucks a gallon in case you guys were wondering. Smiles per gallon > Miles per gallon!!!

The engine computer will compensate on lower octane fuel. You will just have less power and get worse mileage.

Some years ago, I had a friend with a turbo Audi A4. I had the same car. I ran mine on premium fuel; he used regular, and was proud of how much he saved.

I convinced him to try a couple of tanks full of premium and to check his mpg compared to what he usually got, and when he did the arithmetic, he found that the extra cost exactly equated to the extra mpg, plus he had noticeably more power available. He switched to premium after that.

Have been using 91 Octane _ the higher the grade, the better it is for your car. BMW recommends 91 Octane.
