From DodgeRam.org:

"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
> recommend 50% #2, and 50% K1 OR #1 diesel. Is the 1st statement true? I know the second
> is because its in the owners & service manuals.

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
> diesel? I'm more concerned about short duration needs... ie out in a rural
> area and unable to find diesel, but can find a K1 pump.

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."

 

I'm going to assume you mean SXR800 not 700. Sxr's are really great handling skis, but are really heavy. More of a race ski than a freeride/freestyle ski. I've ridden a race prepped one that did 66mph (stock is 50), and let me tell you , it was a white knuckle ride The new sxr has dominated the race course.Standups are the best, sit downs are for grandpas!! Get rid of the GPR - they are only good for flat water drag races and have a lot of powervalve problems unless you get the riva update kit. Also have to get the pump seal kit or you will have problems. The 215 hp machine you refer to - the rxp - also gets left and destroyed by stx-r1200's making less hp in any kind of chop. Also the superchargers are having durability problems. If you really want a hot rod, get a stxr-1200 and put triple pipes on it

I definitely understand your problem - I used to launch my superjet (yamaha's standup) with my Jetta TDI and almost get stuck in the sand all the time.(I just moved up from FL) Sure is nice to have the big CTD

You might want to try amsoil's new oil called Interceptor in your boats. It's about the cleanest burning 2 stroke oil I've ever used and the price is very reasonable - like $16-18/gal. Guys that want to try an ashless 2 stroke oil in their trucks may also consider this oil.

Lastly in reference to canola or natural additives, yes there are some available. I'm not sure about canola specifically, but there are lubricity additives like soyshield etc out there. I don't expect them to be super cheap though.

 

So I am to assume that the lube is some time of 2 cycle oil added to the JP-8? BTW That's a great reference! I have always gotten great info off this site. Thanks!
