and it depends on what tire size and rim size you riding... it also affects the rpm for the speed....

i'm riding on 14" stock tire size... about 3500rpm at 120km/hr...
and if i'm driving at 90km/hr on highway, its roughly 2000-2200rpm

Its not bad to drive your car when its cold. Its bad to rev the **** out of it when the engine is cold. Actually driving the car is better than letting it warm up at idle.

He is right. But i still like to warm up my car long time before i drive it. The best and accurate way is not to rev it and give it that much gas when the car isn't at NOT ( normal operating temperature). U can go on highway it doesn't matter, but just take the gas pedal easy. U should warm up like 2-3 then slow cruising speed.

yea, what electronblue said is right, dont rip the hell out of it and you should be fine.


when im in a rush, i usually let it idle (when its cold it idles at approx 1500rpm) for about 2 or 3 minutes, then i drive but take it very easy (under 2300rpm)

when igot time, i turn it on, leave it idling for about 10 minutes or so and drive normal (which is under 3000rpm so i take it easy all the tiime)

k thanks everyone for the advice, I'll just make sure to keep the rpm's low and the heater off.
