I think according to 'the handbooks' the optimum rev range to drive in for economy, drivability and engine health is between 2000 and 4000 rmp.
Don't really think the third gear 'thing' will help me out much. Apparently you are less likely to break the speed limit in 3rd in a 30 mph zone, but I find it relatively easy to stick to it in 4th or even 5th and also get better mpg into the bargain.

Partly....also i read somewhere that its just as harmful to drive in too LOW a gear to your engine as thrashing it.......is this true?

scooby_si

i guess there's sum truth in that certainly if yer driving at 30mph in 1st gear from cold lol. Maybe it's just me but i laughed when people were talking bout driving at 30 in 5th & saving fuel maybe i had just got used to bad MPG c/o scoob lol
