It could be, because all cars have alot of cold starts. Just think if you started your car once, found a way to change the oil while it's running, and drove on a track until it died. You'd probably get 4-500,000 miles out of it...quote:

365 days in a year.
Say you go to work 225 days/yr.
At minimum, start car once in morning cold and once in afternoon cold.
225 days x 2 cold starts a day = 450 cold start per yr.
450 cold starts x 400 miles = 180,000 miles
450 cold starts x 500 miles = 225,000 miles
So following these guesses, at least according to Sikorsky, your putting 225,000 miles of wear on your engine a year just by cold starts?
This can't be right...
Yeah, I'll think twice next time about starting up just to move my truck and make more room in the garage...quote:

This is also hard on the engine because of the cold shutdown, leaving all the combustion blowby to settle into the oil instead of most of it burning off as it would in an engine brought up to full operating temperature. That is why short trips (say under 10 or so miles) are so hard on engines and oil. This is probably worse than the cold start, at least in summer.quote:

When in doubt, follow the money.quote:

That is true, you MUST let the oil reach all the vital areas of the engine & warm up just a alittle bit BEFORE putting strain on the engine. Also, you shouldn't idle it too long (i.e. like 10 minutes) that is bad for the engine as well and will take forever to warm up. The best way to warm up a vehicle is to idle it for a min or so then drive really slow until the coolant guage goes to normal operating temp. Thats what i think any thoughts??quote:
