hi! i just bought a 2019 colorado with the baby duramax yesterday and I was wondering about using diesel fuel additives in it. I bought a bottle of Power Service Diesel Kleen + Cetane boost because i recognize the brand and we've used it in our semi's. But i also saw "Hot Shot's Secret Everyday Diesel Treatment" where one 16 oz bottle treats 400 gallons. It is reviewed really good on amazon but I was wanting to hear from those of us with this 2.8 duramax to know what works and what doesnt. Thanks in advance.

Not only is additive a good idea, GM recommends AC Delco "diesel fuel conditioner" when Top Tier diesel fuel is unavailable. I prefer Diesel Kleen because it's widely available, affordable, lot of folks I know swear by it and I also use the other Power Service products like biocide and tank cleaner for maintaining my long term fuel storage.
Edit: Diesel Kleen also ticks off all the boxes that GM recommends for multifunctional fuel conditioner, not just improving lubricity.
If TOP TIER Detergent Diesel fuel is not available locally, GM recommends the use of ACDelco Diesel Fuel Conditioner. It is a multifunctional additive that helps clean engine deposits, improves lubricity and cold temperature fuel flow, reduces fuel filter plugging, enhances corrosion protection and fuel stability, and boosts cetane. And if low-quality fuel has already been used, GM recommends adding ACDelco Fuel System Treatment Plus – Diesel to help clean engine deposits.

Some great points! Thanks for the extra info. I used the Amazon prices for the comparison, so guess I should have mentioned that local prices may vary.PS Diesel Kleen is $23.49 locally for me for an 80oz bottle. Nowhere special, Advanced Auto. Which makes it ~ $0.10/gal.
Hot Shot's Secret EDT is $0.05 if you don't use the "super duper" dosing and go with the 400gal option lol.
I've posted this a few times but found it very informative:
Old post (2003), but Diesel Kleen talks about emulsifiers, anti-emulsification, and Diesel Kleen in this post. Not advertising for them, just passing along information that was well presented (for me)

Does PS Diesel Kleen (silver) remove water?
This does not seem to have been covered recently (well I found nothing in the search). Anyways I always fillup at Arco with their ULSD ECD-1 and about 8 oz. or PS Diesel Kleen (silver bottle). I remember before people talking about water emulsifying (not sure if thats the right word) using...forums.tdiclub.com
