Comment Truth on extended car idling .. (Score 0) 454
This is actually true, but it depends on the car. Most newer cars allow a high start idle to reach the necessary oil pressure which is essential in preventing early bearing failure. If the car is properly broken in running it in park for long periods is ok. however most cars when started without a blip on the gas cannot sustain proper oil pressure for safe bearing operation. This will shorten the engine life dramatically
