is kerosene safe to run in a diesel?

[rod77zilla]

hopefully, someone will still read this post and know enough to answer. (if you don't know then don't make something up)... . I did run 5 gal kero/ 5gal diesel mix twice before I got around to posting. (not right in a row. ) Now I'm all paranoid about burning up my injector pump. Was that enough to do any damage?

If you only ran that mix twice, and not in a row, dont worry. It would take more then 2 tank fulls to do any damage.

Rodzilla, if you've already mixed it, I'd throw a little lubercation in the tank to ease your mind.
Howes lubercator is a good addative. If you cant get it locally (at just about any truckstop) a pint to a quart of 2 stroke oil ought to do ya.
You still never said if you have the 12 or 24 valve engine. The 12 valver is much more forgiving in this area, as stated by previous posts.

So if I can get free Jet A from where I work because the tanks are sumped everyday- about 3-5 gallons worth and what I saw comes out looking clean to me, is it worth running it in my P7100 pump, and what kind of lube do I use for the 5% mix that Dave Fritz mentions?

Dave Fritz, I emailed you a question about this.

Thanks.

vc,

I sent you an email, but here is the same information edited a bit to clean up some cut-and-paste problems.

You should have no problem for using Jet A in your 1997 Ram.

Cummins bulletin 3379001-05 (Dated 01-Jan-1995) lists Jet A and Jet A-1 as acceptable for the P7100 pump as long as the fuel meets the lubricity specifications for Cummins engines. The lube spec requires 3100 grams (grams of what it doesn't say - Dave) or greater as measured with the U. S. Army scuffing BOCLE test or Wear Scar Diameter less than . 45 mm at 60°C (WSD less than . 38 mm at 25°C) as measured with the HFRR method.

The typical spec for Jet A and A-1 is 1600 grams based on the U. S. Army Scuffing Bocle test, so you will probably need to add a suitable lube to the fuel.

Fuel mileage will be 5-10% lower with Jet fuel. (who cares if the price is considerably lower!)

For lubrication, you want to add an ashless oil that will not leave deposits in the injectors. Best choices (in descending order of preference): any quality lube additive specially formulated for diesel engines, marvel mystery oil, 2-stroke engine oil, SAE10 non-detergent engine oil. Be aware that 2-stroke oil and many engine oils contain enough sulfur to kill your catalytic converter. NOTE: if you still have the cat - I would recommend that you loose it or gut it before switching to alternative fuels (oops - I didn't really say that, did I?). #ad


Regular engine oils can be used - but they usually contain more additives than non-detergent oils. Use a single weight SAE10 oil to avoid the extra viscosity improvement polymers used in multiweight oils.

ATF must not be mixed into the fuel because it contains friction enhancers and other additives for the clutch packs. All gear oils contain way too much sulfur and phosphorus.

R. ebel, Dave,

thank you gents.
I think I'm going tostart using the FREE fuel and add one of the diesel additives that give extra lube.
I've got some Stanadyne and some Howe's in the garage I'll take a look at and see if they are the extra lube type. I think I've got the ones that are the cleaner types for the injectors and such, but maybe provide extra lubricity as well.

R. ebel, have you had good luck running the Jet A in your rig and how long have you beeb using it?

Thanks again.

Rod77zilla,

Not a bad question at all... and for all the nay sayers out there, the issue is not as clear cut as it seems. The owners manual for the 2004. 5 Dodge does seems to allow alternate fuels. Check out page 267: "Experience has shown that it (CTD) operates on No. 1 fuels OR OTHER FUELS within the specifications in the following chart. " The chart lists the Specs for No. 1 and No. 2, but clearly there is some other type of fuel that Dodge considers safe or they would not print "OR OTHER FUEL. '' It also specifically states do not use alcohol or gasoline as a fuel blending agent, and not to use organically blended diesel fuels, but it does not specifically prohibit kerosene or jet fuel. As Crash alludes to, the military is going to a program called "Single Fuel Forward" where ALL its diesel engine will be run off of JP-8. Testing has shown no adverse effect. JP-8 is essentially kerosene with 3 additives to prevent icing, corrosion and fungus growth.

If running a 50/50 mix of #1 and #2 is so bad on a VP44 shouldn't we see a lot higher failure rate in cold climates? Don't get me wrong I'd rather run straight #2 but the 50/50 winter mix is about all you can get around hear during 5 months of the winter. I haven't noticed that injection pumps are dieing faster in colder climates. Maybe a poll is in order.

Well Well It seems that I have opened a can of worms with this question and I'm glad I asked. Now for all you people who act like it was a dumb idea, I have this to say: I do have all the books on my truck. It tells you how to properly maintain and repair a totally stock truck. It does not tell you what are good ideas and what are bad ideas when it comes to modifying your truck. For example it says nothing about hooking up an EZ box, running smaller turbine housings, K&N air filters, propane injection, nitrous or any of these other modifications that everybody on this website is okay with. I did not know that the injector pump was lubed by the fuel, so I definitely won't be running any kerosene any more. The service manuals are good for dealing with stock trucks in normal driving situations. I was looking at kerosene for performance reasons only. But I do appreciate the responses even though some make me sound like some sort of jackass.

There ya go. There has not been an auto manufacturer that suggests, advises, or promotes enhancing the vehicle beyond OEM in any way shape or form since the late '60's.



BTW, it was not a dumb idea, nor a dumb question. The TDR is where you learn things, and get help if you need it. It is more one of those things where your friends will shout "NO!" if you are about to do something that you really should not do, like bedding down with a really ugly fat chick if you have had one too many drinks. You'll thank us in the morning.

rod77zilla:



To answer your question about a power increase by adding kero, from what Ive heard kero actually has less power/cetane, due to the lack of oil in the fuel. I`m sure your 5gal/5gal mix will not have a catastrophic effect on your pump, but if you ran that everyday, you would see some failure. Up here in snow country, we usually get about 25/75 kero/#2 up to 50/50 depending on the station. If you have cheap kero available, i would think a 25/75 mix wouldnt hurt too much. But you will lose power on any mix with kero.



hope dat helpz

I was always under the impression that #1 diesel and kerosene were the same thing. Are they not? Here in Northern Nevada we get winterized fuel in two forms. A mix of #2 and #1 diesel or #2 diesel with antigelling additives. I like the additive method as it gives more power and better mileage than the mix does. I would be perfectly happy buying #2 year round and taking care of the additve myself.
