OH, just a work, prolonged idle and warmup time is just as detrimental running with no oil....well, not that bad. Acids created during slow warmup attack all surfaces and corrode/wear internal surfaces....if you do not burn them off...they will stay in there and damage further. The ideal is just to turn on teh motor and one oil pressure is up to teh norm, drive normally (i.e. not raggin it) so warmup is fast . And and due to teh nature of oil, you will not wear anyfaster with cold oil as long as it is being pumped round.Quote: Originally posted by MarkB on 29 October 2002
It certainly wont be doing the engine any good, you can limit this by letting it warn up for 10 minutes before driving anywhere - this is what I try to do whenever possible - though I do live about 18 miles from work so it gets a nice run every day.
