I have to agree w/jalopy45. RPM for fuel mileage is about 1900-2200.
3000 RPM will hurt snowman in his quest for better mileage.
Running 3000 RPM will use more fuel as opposed to 2200 RPM, nobody stated excessive RPM is wearing out the bearings,but it is wearing out the bores & rings.
It sounds like snowman is keeping up w/traffic & turning 3000 RPM's, if he brings the rpm's to the more efficient range of 2200 or a bit less, he would be impeding traffic.
So all kidding aside, he does need a OD trans.
