Had the same experience with a marine diesel. It burned oil. Talked to the manufacturer who said I had glazed cylinders because it had been babied during the break in period. He recommended “Italian tuning” Took the boat out and did run it for 3 hours on 90% load. That fixed the problem.

Per Cummins service manual, need to high idle if gonna idle more than 10 minutes straight ..... The most important reason for this is to prevent the lifters from developing a groove in them from a lack of spinning... Flat tappet lifters spin in it's bore at speeds above idle.

Y’all are observant! TRX!! The holy grail of 1/2 ton fun! Love Raptor too

Great input. Thanks.

A buddy had a 6.2 82 Chevy diesel. It was extremely cold so left truck running. 2 days later finally got back to the truck still running lol sure that wasn't good for it!

My truck, will high idle by itself till it gets to 179F if the temps drop down to 169F it will kick in again. 1000RPM

Paul I have a 17 Ram Cummins 2500 6spd manual I only get a high idle at 40°F ambient air temp or lower unless I force it at 50°F with the exhaust brake on with parking brake applied and it will stay active at 1000Rpm till coolant temp reaches 170°F on a cold start engine. So I always start it with the exhaust brake on full on a cold engine. It takes a minute or two but it will jump to high idle under those conditions only. Totally different than the Automatic transmission trucks where it can be forced with cruse control under any condition.

If you’re going to idle for any amount of time high idle it raises oil pressure and moves air if you have a manual fan

Are you going to review the TRX you’re in? Only 250 miles on it too! 😂

I've heard it's bad for the bearings, I turn my to high idle when sitting for extended time. Mostly on warm up on cold days '95 7.3 TS 6 position tuner.

Nice trx

Extended idling is fine as long as it’s raised idling.

I rarely let my car engine idle for more than a minute before putting the gearbox in Drive and slowly driving off. If the outside temperature is below 55-60 degrees, I may wait until I've driven the car for a few miles before turning on the heater.

What about in the Summer? Say 100 degrees Fahrenheit. 2011 Ram 6.7

I drive a 2023 freightliner Cascadia the main reason I keep it running all night is for the air conditioning or the heater Other than that I shut the engine off to preserve fuel . When I 1st got the truck the truck would want to shut off just as a fuel saving precaution but I overrode that but When you run it all night the truck will have a beeping warning sound that means That it needs to go into regens if I don't do regen Then the engine will shut off . But now somehow it goes into regen by itself . I have heard that if it idols all night the idol should be a little higher than usual so that the oil will reach the heads and lubricate everything properly

What tuner do you recommend? same as before?

Did you know you can turn on high idle by turning on cruse control when your idleing

Do you have issues gelling if truck stays running?

Can we get a review of the Trx

Twenty 1st 👊🏻💪🏻

What temperature do you allow your truck to cool to before shutting it down after towing?

Sound is good to me... Looks like you lost your egr cooler in the thumbnail...

Let's hear about that TRX

What about idling a 2009. Audi A3. 1.9 TDI

Ram 1500 trx

Hey Paul, you ever come across a Cummins of yours with the grid heater bolt failure?

Ram TRX

Humm....sounds like straight pipe..

What state are u in? Looks like Wyoming

So hard to hear. Was very interested.

If deleted yeah 😅
