Anyone here have any problems running jet-a fuel in their trucks. Know a guy who ran it in his powerstroke but would mix automatic trans fluid to aid in lubricity. Can I hurt anything on a 12 valve running this slim to none lubricity fuel?

 

need to add some lub to it not atf it has friction modifiers in it, bad for IP .plus it turns fuel red ...looks like off hwy (very bad)

 

we run jet-a in our box trucks here at work, I cant speak for a 12v but we havnt had any problems

 

Don't know about Jet-a, but I've been running Kero in my truck for the past week. I added lube of course.

 

Run alot of furnace oil , smells a little different can't tell the difference otherwise.

 

I spent 36 years dipping sumps on heavy metal and dumped a lot of jet A into the waste tank. I never used it in my vehicles but I knew of guys that did, they just added a little oil to it be it 2 stroke or engine oil. NOT jet engine oil.. Diesel was always cheap and at the time it wasn't worth the mess, but now it's $1.10 or so a liter it's a different story. Go ahead and fill your tank.

 

?Why can't you mix turbine oil in Jet-A for lube?

 

He said add 2 stroke oil that is made to lube fuel systems, DO NOT put jet ENGINE oil in your tank. The manual says Jet-A is fine up to certain amounts if not mixed with lube but if you put lube in it it should be fine.

 

Here's some info from Dodgeram.org.




"Using Other Fuels in a Ram Diesel

For the "inline" P7100 pump ('94 to 98.5 12 Valve engines). P7100 pumps are internally lubricated by engine oil.

These fuels are "OK": #1 & #2 Diesel, 1K & 2K Kerosene, Jet-A, Jet A-1, JP-5, and JP-8.
NOT OK under any circumstances: Jet-B, JP-4, and Cite


The "rotary" VE pump (pre '94) and electronic VP-44 (98.5+ 24 valve) VE and VP-44 pumps are fuel lubricated.

#1-D Diesel or #2 Fuel Oil (diesel) only
Alternate fuels listed for the P7100 pump may be used in the VE pump if if 5% lube oil is added.


The P7100 inline pump is internally lubricated by engine oil, while the VE and VP-44 pumps are fuel lubricated. The "lighter" fuels, such as Kerosene, Jet-A, and JP-5/8, don't lubricate enough.

Note: there have been some reports of sticking plungers in some early P7100 pumps. There are many commercial fuel additives which contain a pump lube - to avoid plunger trouble, consider using an additive when the engine is running on an alternate fuel.

Fuel Tidbits from the Bradley Bits - a news bulletin for Bradley Fighting Vehicles

JET A-1 fuel is essentially identical to JP-8 except it does not have three additives required in JP-8: a fuel system icing inhibitor, a corrosion inhibitor, and a static dissipater additive. Hot JP-8 fuel reduces the life of fuel pumps on some diesel engines, so avoid using JP-8 or Jet A-1 extensively in hot heather, and keep the fuel tank as full as possible to reduce fuel temperature.
Diesel fuel #2 and water separate completely; JP-8 fuel and water do not. JP-8 becomes cloudy when contaminated with water; and the cloudier the fuel, the more severe the contamination. The Ram fuel/water separator will not be able to remove suspended water from JP-8 or Jet A-1.



Some Questions answered by Josh Berman of Cummins:

> Dodge says to run #2 diesel under most conditions. In "arctic" conditions (<10 °F), others

Blending is better than running on fully on #1 or K1, because it will keep your power output closer to that of running on #2 Diesel.

> What if any problems will be caused by extended operation on other than #2

If you have a '94 to '98.5 12 Valve truck, then you should have no problems running a tank of K1 (2K Kerosene, Jet-A, Jet A-1, JP-5, or JP-8) through your truck. You might find that it performs differently (ie: #1 Diesel gives lower power than #2 Diesel), but it should not cause any damage to your engine. (Note: Jet-B, JP-4, and Gasoline are NOT to be used in any models. Dave)

However, if you have a 1989 to 1993 Ram or a 1998 and up 24 valve engine, then we DO NOT recommend using any fuel other than #1 or #2 Diesel. In an emergency, you can use 1K or 2K Kerosene, Jet-A, Jet A-1, JP-5, or JP-8 ONLY IF YOU BLEND 5% NEW LUBE OIL with the fuels (ie: 20 gallon fill-up, add 1 gallon new lube oil). Adding the lube oil is VERY IMPORTANT, as running on the lighter fuels without additional lubrication will cause excessive wear in your fuel pump, which is not a warrantable repair.
CAUTION: Running fuel other than #1 or #2 diesel w/5% lube oil should only be done if there is ABSOLUTELY NO OTHER CHOICE. Fuel pump damage due to inadequate fuel lubrication IS NOT COVERED BY WARRANTY, we don't recommend "lighter fuels + 5% lube oil" unless you're in a really desperate situation."

 

Jet engine oil (turbine oil) be it Castrol 5000, 2380, 254, Mobil Jet 2, are made to MIL-L-23699C or MIL-L-23699E which has a MINIMUM flash point of 475 deg F most newer oils are higher, Mobil Jet 2 is 545 deg F. On start up my idle temps are around 250 deg F, I know thats not in the combustion chamber but... The high flash point alone would stop me from using it. While all these oils are a SYNTHETIC ESTER BASED LUBRICANTS its what each manufacturer puts in as chemical additives that will not only destroy rubber lines and seals very quickly but are not designed to be burnt at low temps, you would have no idea what is coming out the tail pipe.

 

So I guess I could mix a few gallons of JP-5 in with a tank of #2 diesel to take my $100+ per tank just a little further (with a little 2 cycle oil of course)?

 

why would you want to pay for jet-a? i priced it locally and it runs around 4 to 4.50 a gallon.

 

Well, I can't speak for amttap, but I wouldn't be paying for it

 

The truck will start easier, the fuel won't gel up until about -40*C, and you won't need any fuel heat for de-waxing the filter. You will probably get about 10% less miles/gallon. It's quite a bit more refined and some of the energy has been removed as well. It weighs about 0.2#/gallon less than #2 diesel. Good luck and you don't need to mix anything with it, we use it in the air force trucks and ground equipment all the time.

 

yeah, i can understand using it if it's free. if a thousand gallons happened to land in my yard, i would certainly find a use for it.
