Fuel economy... your MPG?

[Ferret]

I try not to work it out. Paying $8 a gallon with a V8 is barking mad.I'd sell it if I knew the true figure.

Haha, this made me laugh out loud

I have an e34 bmw 520i m50b20 I have tested using the lowest octane in europe...and the highest ,,,(95-99) octane .I ran 6 tanks of each and consistently found the higher to be about 10 percent better (city driving) long trips were maybe 5 percent (10lt per 100km-99oct and 11+ litres with 95 octane)..also my engine is alot quieter with the high but I dont' know if 99 octane is overkill for my car,is it causing any damage?,budget wise i think i am better off with the 99 octane but I would like to know if it's bad for my car

It shouldn't be a problem. I believe the VANOS-equipped M50 engines have a knock sensor, which allows the engine to adjust the spark timing to benefit from high octane fuel. Non-VANOS M50, M20, and M30 engines do not have a knock sensor, and therefore will not benefit from higher octane than recommended, and may be more inclined to carbon up if you use higher octane fuel than recommended.

Translating 13.2 l/100 km gets me 21.5 mpg (imperial gallons @ 4.55 litres) overall city and country. A bit better than 28 mpg sustained highway driving. Around 18 mpg city driving. Worse than 14 mpg enthusiastic hills driving ....

The old e34 gets 26 mpg in 25% city 75% hwy driving , the jeeps gets 12, the vw 45 and the suby gets 23.
