Re: RPM Question

There is a difference between cruising at very low RPM down the freeway(not even possible in a DSM, unless you are one of those people that drive 45mph in the passing lane) and lugging a motor. It doesn't take much HP to keep a car cruising and you can get away with running it at a low RPM, if you try to accelerate more than slightly, then you might end up lugging the motor. Who knows if there would be damage from lugging it though. We aren't driving old non EFI cars that might detonate easy from low RPM lugging because of their primitive ignition timing system. If there is adequate oil pressure, there shouldn't be problems keeping the rods and crank off of the bearings, since the cylinder pressures should be quite low. If anything, it might be hardest on the pistons and cylinder walls.
