<< << I like overdrive. Low RPM=longer engine life and better gas mileage >>
A common misconception.
With most smaller engines it's much harder on them to "lug" the engine (not keep the RPM's up) than it is to rev them higher.
I like to keep my "R's" at about 4000. Hence I drive in 3rd gear a lot. >>
A common misconception my ass. :Q While its may be true that lugging the engine is more stressful, if you're driving right, you should never lug your engine.
RPMs kill, period. You should never take your engine to the redline. It's considered the safest max RPMs for the design of your engine.
Just think. If your engine has an 8000rpm redline, at that point each one of your pistons are moving up and down 133 times a second. :Q
If you took two engines.. stuck one at 8000rpm with no load, and one at 5000rpm with a load, which one do you think is going to last longer, all other things being equal? Yeah, that's what I thought.
