"Feeling" has nothing to do with it. RPM is probably the most governing factor factor as it takes into account the best torque and RPM points the engine is delivering. We all know the results of exceeding the maxumum point....bent valves, spun bearings, and a catastrophic component failure. My second choice is oil pressure, for without adequate pressure, the engine would not survive (especially at high RPM). A sudden spike in coolant temp, may be a precursor of head gasket failure or leakage. For these reasons, I'll stay with my choices....but you can continue to use "a feeling" as the determining factor.....your choice....Tach as a first one ?... when you know your car you can feel the RPMs but I find hard to feel oil, temp and gas. Just my 2cents
