Mine for 93 octane about 2.95$ (usd) not too bad

damm u guys are missin out we go 100 over here, my 328 loves it! lol

[theluis]

how much are you paying for 100??

[SpeedInfusion]

there is 100 in the states too, just not as common.

last time i checked,which was like 4 years ago, 100 was $8 a gallon

[chenn714]

Its like £1.20 per litre, so a full tank is like £60-£70 but its well worth it

[PhatCat]

91 normally in the 'ol e30, it runs about $1.20(ish) per litre on the North side of the 49th.

Check your owners manual. What BMW recommends is listed in there. However it usually is 89 at a minimum. Most people run 91 just because it's better for the engine. BMW states that with a better octane it will improve your mileage.

I agree, low octane isn't good as it runs leaner, causing heat ! (Not much but enough)

[Bockbmw]

Your right,te manual says 89 and above.Thanks for the information.

[Snypa-D]

I use Tesco Momentum 99 or Shell V-Power 99 as my car has modifications and a remap it wont run properly on anything else,bit pricey but well worth the extra pennies

I am not a professional. This my opinion. I could be wrong.

STOP!!! STOP!! STOP!! TIME OUT!

#1. Always use what the manufacture recommends.
#2. Using a higher octane does not increase performance.
#3. Using a higher octane can lower performance in some vehicles.
#4. Late model cars come with knock sensors that prevent you having to use
a higher octane due to engine knock.
#5. Unless your car is heavily modified and creates enough combustion heat using
91 and up octane is just a waist of money.
#6. Higher Octane has no extra cleaning and anti corrosion additives than any of the
lower octane.

Yes back in the old day's using higher octane levels helped with "Engine Knock". It still did not make any actual performance gain. Today we have computers, sensors, and actuators that work together to keep combustion temps low. Not to mention EGR valves and or Variable valve timing.
