I think if I had 1trip nonstop I could tease 550 miles out of a 335i. Which is pretty impressive, but a very boring trip that would be!!
I reckon I could do drag 600+ miles out of a tank if I was doing it on a constant 48mph motorway journey....and being overtaken by really angry lorry drivers - 48mph seems to be about as low as I can get RPM-wise in top gear before it wants to drop down a gear so I'd guess that'd be the ideal speed to extract maximum MPG!
