My day can include hours of call/email time that don’t always make sense to go back to a building for. My truck has been panning out to be a fantastic mobile office and I’m comfortable on my phone and laptop for hours at a time.... with one catch. Often I need the vehicle running to stay comfortable.
So, before I start racking up idle hours... in a 6.2, what are the implications of idling for as much as 50% of hour-wise usage? Does setting up the high-idle mod do anything for longevity? Should I just suck it up and get double-layered or naked as required?
I wouldn’t worry about it other than just watching the temps. Look at police cruisers, they probably spend half their life or more just idling. I saw a crown Vic one time that had over 14k idle hours. They started putting those on in later to years to specifically track the number of idle hours for maintenance purposes.
The fleets I work with running gas trucks are on a 300 hour service interval, so far its been working out well for them. This is F-150s with 5.0's and Super duty trucks with 6.2 and 6.8 engines.
in addition to engine hours and more frequent oil changes I wondered if there was a minimum RPM for proper oil circulation that for fuel efficiency regular idle falls below.
Our mini and Volvo (turbo charged, super and turbo charged tiny *** engines) aren’t supposed to be idled for long. So I was thinking it might be a situation where I should be setting up a high idle or something. Granted, this American truck has three times the engine of either the mini or Volvo....
My $.02 is that you’re fine. Keep the oil changed regularly and keep a general eye on stuff, but the 6.2 idling very frequently is a MUCH better option than the 6.7. Today’s diesels get much more crabby just idling than they used to, with the lower combustion temps wanting to mess with the $$$$ after treatment stuff.
There is no legit reason to use a high-idle feature just to sit and use the truck as a mobile office. Even with the AC running, there's enough charging capacity that it should be fine.
High-idle is a tool for trucks with a LARGE amount of amps being drawn, or running PTO take-off equipment. You are doing neither.
As for the oil change cycle, just follow the OLM. Of all the UOAs I've seen on this engine, there's nothing to concern yourself with. The oil system does a good job in the 6.2L.
