Remember that your engine warms up faster at higher revs, so idling at 1000rpm till the temps go all the way up means your car has spent 5-10 minutes running at low temp.
So it can be argued that your better off by revving the engine a bit more to help it warm up faster.
I let it warm up till the revs fall to 1500rpm, then drive it slowly (keeping revs under 4k) till the temp rises. This also warms the drive train up together with the engine.
If in doubt: warm car up for 1-2mins, drive slowly to allow parts to warm up to norm operating temps. Try not to make short trips, especially on cold days as the moist air during cold mornings condensates inside exhuast pipes etc. causing it to rust quicker. Use good lube, something not to thick to allow easy flow on high revs. (vtec) especially for those who drive on vtec every gear (and so that the next buyer of your car doesnt not end up with a dud cause you neglected the car) and service car regularly... that way the car will run as smooth as a babys bottom.
ok so ive heard some people say that idling for to long is bad for the car but with no explanation..... can anyone tell me why its bad?
does warming up the car have any thing to do with compression and the computer??
cause what im saying is, is that when i turn the car on dont let it warm up slow once at operating temp its got less power, then if i leave it for a few min and do it slow.
I think they refer to overheating while stationary. No airflow through the radiator to cool it down and the problem is worse with the airconditioner on. Watch your temp guage while stuck in macca's drive through.Quote:
