Excessive Idling

Excessive Idling
I have a customer that sits in his truck at idle for 20 min periods maybe 6 to seven times a day, He may drive it a mile or two and sometimes an actual road trip of about 20 miles. In this situation its a 2006 GMC Sierra 1500.
What I am curious about is the impact on the engine and different components, i.e. 02 sensors, knock sensors, plugs, etc. Also does the oil life algorithm take this into consideration.
Although seem to concerned about the gas mileage or lack there, he is starting to get some codes, Although the codes are in line with the mileage (156000) I cant help but think the extended idling isn't some how part of part failure, plugs, 02, etc. Was just hoping for some more definitive input.

Agree with Henry. All that idling is wasting fuel. Unless you live in Alaska or Siberia, there's no need for such extended idling. I doubt the idling has much to do with any fault codes.
Yes, the oil change algorithm takes the idling into account. It'll just trigger the oil change reminder light to come on earlier.

no, idling shouldn't hurt the engine. Taxis and police do a lot more idling than he does.
I'm pretty sure that the oil life monitor counts the time the engine is running. (among other things). It usually reach 0% right around 200h for me.

No. I change it every 5000 miles. Back in the day, when carburetors wasted lots of fuel, it was every 3000 miles. I don't idle that much anyhow. I use top-grade synthetic oil, filter, and mostly Chevron fuel, BTW.

ok well the engine is still combusting, and the parts are moving and rubbing on each other when the engine is idling.

Some gases escape, but some combustion products dissolve in the oil. Soot and crap like that. The oil oxidizes and becomes more acidic over time.
My point is simply that oil still wears out when you idle. It doesn't sound like you understood the poster's question. He's not warming up the car.
