Idle or shut down?

1063423

{"text":"I began training during the winter and was taught to leave the engine on and idling while waiting at customer, 30 minute break, and 10 hour break. This would prevent a cold engine start and keep the cab warm/protection from the elements. \nNow that the weather has been getting warmer I'm wondering if there's any risk to shutting down the engine instead. \nAny thoughts/suggestions?

{"replyTo":"","text":"If your company doesn’t care about idling overnight, I would still do it in the summer when it gets hot and keep the air on. If it’s your own truck, you pay more in fuel and engines hours which could cause repairs sooner in the long run. I’ve heard it can wear on the DEF sensor faster especially with idling every night.","replyToPid":0}

{"replyTo":"","text":"Most trucks have a low idle cruise, it is designed to keep the AC compressor and the alternator running at a comfortable speed for them. Idling all the way down can cause higher AC pressures because of not passing enough air across the AC condenser. Turn your fan switch on, idle at the sweet spot where your engine feels smooth between 800 and 1000 RPMs your truck was designed for this.","replyToPid":0}

{"replyTo":"","text":"Bad advice. Now if you did not treat your diesel with antigel, then do keep the engine running, but if it’s below zero, you’ll probably gel up.\n\nI personally turn off my truck if I won’t be using it in the next 5 or so minutes. I do have an APU and Espar heater. I also always treat my diesel with antigel before heading into areas with temperatures under 30.","replyToPid":0}
