Aye, someone on here said to me recently (sorry, forgot who  ) that high revs are more efficient. Probably a certain range is most efficient though.

True. 4.5krpm would not be economical in a 12v.

It'll be doing 2500 rpm at 50 mph, and 4500 rpm at 90 mph.
Sorry, I'll be more precise next time

Not necessarily high revs but your engine will be more efficient in a certain rev range instead of just sitting struggling at low revs.

Thank you.
To be fair, if your asking about mpg, it normally is a given that you are being very pedantic about miles and fuel - therefore giving two wrong options doesn't really help does it?
