Fuel Additive

I used to believe this also. Now, I’m not so sure.
This is my ‘14,View attachment 126157
and I believe the idle hours are not accurate. I’m the original owner and I do not idle the truck. This truck has been plagued with emissions issues.
This is my ‘14 work truck,View attachment 126158 it has never had an emissions issue. We have a handful of these trucks at work with similar hours/miles and not one has had an issue. All these trucks run the same additive, Powerservice white bottle.

Wow, that is a lot of idle hours.

What is a CP4 and CP3?

Personally, I think using high idle at warm-up when the engine is cold is much better for it. Especially for those of you that use 15w-40 oil.

It gets the oil and the fluids moving faster. It gets lubrication to where it belongs quicker.

I wish UConnect had a way to engange High Idle when remote starting. That might make it a little more worthwhile.

Still not worth it, IMO. Even when it was free I didn't bother with it much. Half the time, the truck wouldn't start due to no signal if it was cloudy, if you were near or, especially, under a tree or if a bird flew over and flatulated.

My 2020 does have a high idle on cold start. It kicks in after a minute or two.

I use to drive dump truck for the County years back and about 2010 the shop told us not to idle since there was un-burnt fuel build up that would damage something (don't remember).

From what I understand, some (many) of the older diesels would have a bunch of fuel leak past the rings and into the crankcase. Crankcase dilution can cause problems. Wet Stacking is no fun either, from what I understand. Dunno. I never had the problem but many of the older engines did

CP3 and CP4 refer to the model of the Bosch high pressure fuel pump.

You want a CP3 equipped truck.... That means don't buy a 2019 or 2020 as those are the ONLY years that RAM used the CP4 pump.... Which can fail and destroy everything downstream (injectors). They say they have a "cure" in the works but no details as of yet.

2003 to 2018 have the CP3
2019 to 2020 have the CP4
2021 onwards have the CP3 (after they realized they made a huge mistake going to a CP4)

Any diesel can experience wet stacking, even HPCR's.

Cummins defines anything over 10 minutes as excessive idling. That's 16.6% idle time.

3-5 minutes is what the recommend in cold weather.

I .just turn on the cruise and it kicks it up to 1000 RPMs when I have to idle for any length of time .

Go with OptiLube XPD... It's better than Stanadyne.

Is this the optilube you were recomending?

Looks like according to their site that XL has more lubricity additive, I was going to get some and add it to the tank on that 2012 that I am working on (purging the unleaded out) so maybe the XL would be better?
