I have an auto start on my car that allows me to leave the engine running for 1 minute after I am through driving my car. I was told, because my car has turbo, I should leave it run to cool off the turbo.

Is this true?

well it adds more bearing life to the turbo, as the oil doesnt burn off and leave deposits in the bearing surfaces.

you should allow your engine to idle for at least a minute after normal driving if you want your turbo to last.

See this is what I dont understand, if your just driving normally your oil should not be cooking, so there should be no cool down. I was always under the assumption that it is bad to boost the hell out of it and then just park and turn teh car off. I run heavy equipment for a living and the procedure for shutdown is to run the motor at 1/2 to 1/4 throttle for 1-2 minutes and then shut down not sit at idle for 1-2, and let me tell you those turbo's will last for YEARS almost always at full boost if the proper procedure is followed for cool down.......

Don't buy a buddy club security timer! I let my car idle for two minutes with very lightly pressing on the gas every 20-30 seconds. I have to do this bullshit until I replace the old POS buddy club turbo timer.

Its funny because some of our military equipment have turbos and i am able to shut down my engine after running it all day and the turbo has not gone bad. Now that i have said that I do my check every time i start it and shut it down for anything. thats my opinion maybe different with cars But i have had the same equipment for 2 years now and no issues even when i drove it in Iraq all day.

you can't compare industrial equipment to daily driven cars. I could take a pic of the several turbo motors it takes to run one giant crane here at the port of palm beach. ive seen turbos bigger than my steering wheel in person and massive ones online. nonetheless industrial vehicles are built super tough. when you're building a car(at least from my experience) you're trying to get your car to industrial standards of efficiency and lifespan survival. obviously some don't aim for this and are all out top fuel dragsters and things failing are expected.
