Are fuel additives worth running in your Cummins diesel??

[@DirectCurrent4u]

I have been using XPD Opti Lube in my 05 Cummins for the past 3 years and I think it runs much smoother when towing heavy loads! But any fuel additive is better than none for sure. Great video!👍

Opti lube xdp tested the best in lab results

I've only used diesel kleen in my 03 5.9 with 285000 miles and she still runs great

Interesting! Thanks.

[@livingeveryday777]

Hotshots extreme and EDT are overall best 👌

[@donniediesel6.789]

Great video! All that said, which additive are you choosing to start using now?

I ran klotz 2 stroke oil in my 12v and 24v. I contacted klotz and they told me a better option for fuel lube is to run klotz uplon in my cummins.

I have a 4g 6.7 Cummins and have run Amsoil All-In-one. I think it helps. I think the Repair Geek’s video makes me want to try Opti Lube XPD. I haven’t tried it yet though. Lubricity, cleaning injectors, and cetane increases are all good (if the products actually work)

It made everyone want to try it. Good luck finding any. I put in an order and was given a 2 week waiting period before they get any back in stock. Picked up a bottle of Archoil to get me by until then.

I found my 05 5.9 runs smoother on Redline 85 Plus. It has high lubricity and a cetane boost. The fuel additives will save your fuel pump.

I like to run a quart of free new 15-40 oil from work. In my 5.9. Is it good. Fuck if I know.....
