Should I be adding stuff to my tanks when I fill up?  2012 f350 and 2008 Ram 2500.

Nah. Just maybe in winter.

Would you say additive is a must with LSDF?

Run in every tank! I've used power service for 15 years in the same truck, water is the problem. Diesel loves to suck up water, the common rail in your cummins is the same system as a duramax, Bosch injectors running 30,000 psi do not like water or particulate.





Run in every tank. Buy fuel from a high volume station when you can. Change filters regularly.

I have used Stanadyne performance formula in a 12 valve Cummins, a 24 valve Cummins and a Kubota tractor for over 10 years.  No complaints. MBanning

Stanadyne.  Makes my Duramax smooth as butter and more responsive.

Honestly, just run an additive, anything you can find for a good price.  Anything is better than the crap they sell us for diesel now.

POWER SERVICE....see first line in my response....it's a brand, white bottle for cold temps, grey bottle for summer, red bottle in case the filters wax in very cold temps, add directly to filter and tank.

Yeah stanadyne is the factory recommendation, it's a demulsifier PS is an emulsifier(sp?) I have seen what free water does in a tank of diesel...it grows all kinds of fun bugs.

Yeah I'll have to check it out...years ago you couldn't beat an answer out of them about it but the consensus in the dmax community was that it was an emulsifier.

Cummins engineer checking in.  No additives needed if your are keeping up with filter changes and draining water from filter.  Some places in the US do have some sope issues, so an additive to deal with soap deposits could be used.  Too many people have done more harm than good putting stuff that doesnt belong in thier fuel tank.  If we designed the engine to need additives it would be in the manual.

Yea I'm over at DieselPlace as well.  PS has opened up lately with all the new competition around.  If I cant find Stanadyne, I run DK 50/50 with 2 cycle.  Good stuff.

I think Stanadyne was recommended by GM if the consumer insisted on an additive.  Bosch supplies fuel system parts for all 3 trucks.  

Stanadyne used to / still does make injectors and fuel pumps.  They know a thing or two.

7.3s were good motors...not exactly the same as a common rail system as far as the demands placed on fuel systems though.

My only contribution to this thread is that Stanadyne should know a thing or two about fucked up Diesel fuel systems.

Ran a fleet of 300,000+ mile Cummins trucks with no additive and no problems. Currently running a 275,000 mile dirtymax with no additive and no problems.

I bet if cummins offered a 300k warranty on fuel system components you'd take every opportunity to help it live longer.  Cummins uses Bosch components anyway. Injectors, regulators and cp4 pumps are all bosch...how much does cummins influence the design of these components?

Waste of money.

Except for anti gell in winter.

Anyone running tranny fluid or motor oil is fucking up as they are designed to resist burning off.

Worst looking injectors or pistons come out of motors running oils not designed to be used as fuel.

Two stroke is the best choice if you have to.

I got 250k miles out of a VP44 without any additives, and it is probably the least reliable injection pump ever.

And if you use 2-stroke, make sure it's not red, in the event you get your tank dipped by highway patrol...

But yeah, I used winter power service during severe cold snaps (-15 or worse) to help ward off gelling. That was it. Traded off Duramax wih 230k miles.

My father bought a '83 MB 300SD in 1984. When he bought it, the mechanic in the dealership recommended putting a couple of ounces of outboard oil in the tank with every fillup.  He gave that car to me a few years ago and it now has 670k on the clock.  I don't know if the outboard oil has been a "secret" to the longevity of that engine, but I'll be damned if I'm going to break the habit now!  :)

Yes, cold temps are an issue with Bio  

We have B5 mandated, so I don't have to add any
A warm (fuggin' HOT!!) climate is good for a few things.

Vast majority of fuel additives in the US  are made by a single company.


I know this. Because my trucks haul it in bulk.

Name a major brand. They either make it, or make the base components for it.

Then I haul it.

Diesels aren't oil burners any more.

Fuel mapping has leaned them out. Adding more oil, adds more ash. Ash builds up in the dpf faster, which leads to more regens, which means to a faster replacement of a dpf.

Fuel additives has completely changed in the last 3-4 years and is continuing to change as engines and emissions standards change.
