BMW E36 M44 2,93 medium size LSD (was 3,3 small open )

6,5 litre /100km in highway if you driving 90-100km/h, 1 litre less than was before.
8,5-9 liters/100km in town, 0,5 lire less than it was before.

Hrmm...let me find a calculator...8,5/6,5 L/100KM is 28/36mpg roughly. Your mileage is similar despite the gearing advantage you have. Odd, isn't that? Either you drive like a maniac, your fuel has more alcohol, or your engine mods are flowing more air. What's your baseline HP again?

...if only we used the metric system here. Triumph of idiocy if you ask me, keeping the english system.

e36 318is coupe weight 1240kg, a/c, power steering...

E30 318is coup� weight 1125kg (IAW factory papers 6,4(36,7mpg) and 10,9l/100km (21.6mpg).

It's real life, if I would drive like maniac consumptions would be over 10L/100km (23.5mpg), do not trust factory papers

p.s. and I am lucky to start my job late and to finish 12hr shift late in the evening, so I drive without big traffic, otherwise in town consumptions would be over 10l/100km...

Engine M44 and car E36 coupe is completely stock.

You know I work on jet boeing 737 and turboprop aircrafts for 6 years and all of them have imperial size bolts and I still hate it

Must be the fuel you're using, hard to figure on the different mixtures of gasoline internationally. We can get mixtures of over 10% alcohol here, 5-10% is normal (and not required to identify at the pump). It's the preferred way to deal with octane boosting too. But it really cuts into fuel mileage.

737's have SAE/english bolts? Idiotic. I hate measuring in 'standard' units. Yards, feet & inches are OK but figuring in fractionals really bites. Describing something as simple as a bolt can be trouble in SAE units. Imagine how much money we could have saved with a single world standard!

Fuel in Lithuania is RON 95 and 98. Also available E85. I use RON 95.
