Fuel Additives

luvrbus · February 14, 2021, 05:09:56 AM

I am not one to add additives to fuel,since I have a EGR engine it has been recommenced that I use a additive by Cummins to make the fuel burn cleaner in the EGR.Cummins has one brand they approve my guy at Cummins says that Stanadyne is better than the approved Power Service ? is have you guys used Stanadyne

I went to a seminar once on fuel additives and Stanadyne was rated the best but a little pricey. The seminar was put on by an injector rebuilder so not associated with any engine mfg.

Read up on Max Mileage FBC. (https://pittsburghpower.com/pages/max-mileage) I have used it for six months in my two 7.3 powerstrokes and the 8v92 in the bus they all run smoother on it, not a lot in the way of mileage improvements.

Don't want to sound smart, this time, but I would get on a Cummins forum or truckers forum or on Facebook even and pose that question. Since they really put on the miles, they should be good for recommendations and what they actually use.

Does this reduce black smoke from my 9F90 injectors? lvmci...

I ordered 4 gals so I am going to try it when talking with Paul at Cummins after they did up dates on the EGR and with Kevin another friend both told me to maintain the EGR.LOL. I was shocked when Paul told me a rebuild on a ISX 15 could cost from $45,000 to $60,000 caused by the EGR,60k will buy a lot of additives and fuel

,I am fine with my fuel mileage

Rebuilding a Cummins has always been costly. Much more than doing a Detroit back in the 70's. All those expensive orings and seals didn't help. Seems like every one needed the crank ground. Rare for that on the Detroits.

Gone are the days when you could rebuild a 2 stroke for less than $200.00 a cylinder,Detriot OEM sleeve and pistons are close to $500.00 ea ,a machine shops that knows what they are doing charges a $1000.00 a head now ,only thing Detroit sells in a kit are head gaskets seals the rest is i gasket at a time, friggn injector jumper tube the tiny o-rings after market from Pc Industries were $,88 ea X 32 LOL ask Van what a 8v92 cost to rebuild just for parts

Same for Onan parts. That's why some companies ending up buying the rights to discontinued and obsolete things. They then can charge whatever the market will bear.
I'm on some GM pickup forums and what people are paying for engine and transmission rebuilds makes my eyes water. I only used to charge a couple hundred labor to rebuild an engine, but that was several years ago now.

You by chance have a 6.5 GM turbo model.my Humvee has a 6.2 that was new but something has come loose and it locked up and I don't have time to tear it down

Those of you that are advocating for using additives, are you talking about do so for vintage engines or for newer engines?

I am taking about the newer 4 strokes with the EGR,it is ok for the 2 strokes I think because it increases the Cetane number in the fuel for cleaner firing

Stanadyne was pushed by Ford dealers to try and fix the stiction problem with the new 6.0 L in 03, 04 when they couldn't figure it out. I still have a 6.0 that I deleted and bullet proofed. Great engine once fixed. But I now use Archoil in the oil, and Stanadyne in the fuel. Runs great. I haven't had a chance to drive the new Country Coach with the Cummins, but I'll use Stanadyne in it.
