I recently sold my 91' E-34 M5 and it was a daily driver. On the highway it AVG about 21, if you set the cruise and just sailed the max was about 23. In the city my overall average was 16.7 on the computer. Just keep your foot out of it and you'll see a big difference. :)

00' Estoril M Coupe

A few months ago I bought a 91 E34 M5 with [email protected] Tri-Flo exhaust and Dinan chip/suspension. I am getting around 13.5 MPG!?!?! Is this unusaul? I put Techron and Heet in the gas tank, but the improvement was only 3/10 mile. Anything else I can do?

Any advise is appreciated
