Hi, 2006 Dodge Cummins with 325hp engine. Which additives, or lack of them do you like? From the Drew's Brew faq thread, the consensus seems to be MMO + PSD or Walmart 2 stroke + PSD.

But with the changes in these engines, is there a particular additive that works best? This is a California model if that makes a diff.

I just want to make sure my engine is happy despite the reduction in sulfur in fuel but not gunk anything up.

Thanks for recommendations.

Matt

 

I cant help youhere, I ran wvo and pump diesel blend in my truck.

 

I tried some 2 stroke in mine and it didn't like it. Lower mileage (hand calculated) and general anticlimactic impression of performance. Next tank without it and it's a demon.

From what I've read, the 2004.5 (or maybe 2003) designed for LSD (as opposed to ULSD or the psychedelic drug) basically don't benefit from like the earlier diesels with the old lift pumps, etc.

If I try again, I'm going to go with a lot lower ratio. 200:1 max. Unless someone says otherwise, I may avoid entirely and just go with straight diesel and maybe occasional psd.
