Pick my next 1/2 ton pickup

Love the write up - thanks for taking the time!!

Do you live in a cold climate? I'm in NW Montana and have heard from guys that their DEF consumption goes up to almost 1/4 to 1 ratio with fuel in the winters.

I'll watch for oil consumption... I have read that this can be from the DFM system - do you have a DFM disable in your yukon or do you just drive it normal? I'm considering doing a DFM disable and if the headers go, a long term delete. I usually drive it in M and set the transmission to "9" to stay in V8 mode. Mixed commute driving I'm seeing around 15.5-16 mpg with the 6.2. Haven't taken it on a road trip yet but based on the MPG estimates for quick highway jonts, looks like it will be around 20-21ish.

We just drive the Yukon normal, I have the auto stop eliminator on my 3.0 but not on the 6.2, my wife likes that option on the hwy we have seen the same in the 6.2, my best mileage in the 3.0 was 31mpg over 400 miles but that was pretty much all down hill. On avg I get 27-28mpg on the highway.

It does get cold in KS, we have had temps down around -13 but it isn’t for periods as long as you may see in MT. So far I’ve never noticed any increased consumption due to winter temps, we’ll get cold temps though.

This literally came out the week after I picked up my 2019 with the 6.2 lol. I work at a credit union, and we offer good extended warrantees... so I have a 6-year 120k mile warranty. Will be curious to see if GM responds and is able to find a fix... I hope so!

I'm curious how many of the issues seen are "covid cars" with out of spec parts etc.

Warranty is useless if they can't get the parts just ask the diesel guys with the cp4 pumps...6 month wait on parts before the 20k top end motor rebuild.

I’m happy with my 22 F150 Tremor 3.5, sometimes I kind of wish I waited 1 more year for the 5.0 only reason though so I could throw a supercharger on it. I did invest in a tuner from MPT that’s helped with the shifting which was my main dislike.

The cp4 hasn’t been used in years by GM.

For GM trucks, the CP4 was standard between 2011 and 2016 on the LML and LGH Duramax engines. GM switched to the Denso HP4 in 2017 when they released the L5P Duramax. Ram didn't put a CP4 pump in its trucks until 2019 for the 6.7-liter diesel engine.
