RE: 390 Wear vs. RPM |

Running at peak torque or lower is recommended. You get your best gas mileage there if your have a heavy load. If your just cruising, the engine pulls hard if you floor it and don't down shift.
More revs also means more wear on everything from engine parts through the rest of the drrive train. Thats why the rear axle gear ratio is usually set to the lowest RPM that won't lug the engine at freeway speeds under normal loads. |
