I have access to large quantities of "Jet-A" jet fuel, can I run this in my gen 3 or not? We buy 8000 gallons at a time and my cost would be around $2.20 per galon.

 

Yes, but you need to run a lubricity additive such as Stanadyne Lubricity Formula. Also beware of the taxman.

 

I'm thinking that Jet-A is the same as JP-8. If so, I wouldn't run it. It has even less lubrication than low sulphur #2 and is almost a solvent. It will clean out you fuel system real well. Some manufacturers will void IP warranties. It also has about 10% less "power". We've noticed a much higher failure rate on the Stanadyne IP's (6.2 and 6.5 GM engines). TACOM (Tank/Automotive Command) sent out a notice about adding engine oil to the fuel to increase lubricity and decrease pump failure.
It's your call.

 

So what about a mix of used motor oil and "Jet -A"?
Any idea how much to mix of each?

 

The only trucks that can safely run jet fuel (with Lube) are the 12V's....

Very risky running it on a CP3 truck.

 

Ok, I guess I need to come up with another plan. Thanks for the info..

 

10% mixture of 30W non-detergent motor oil.

The cost benefit might not be worthwhile the long run.

JMNSHO, and YMMV.

 

I don't think I would run 100% Jet-A, as stated before, the fuel is too dry(not enough lubrication for the pumps). A 50-50 mix shouldn't hurt anything though. Jet-A is just highly purified(filtered) Kerosene, AKA #1 fuel oil. After all, during the winter in the colder areas like here, your #2 is cut sometimes up to 35% with kero anyway. If you wanted to run a 50-50 mix, like I said, I wouldn't worry about anything, except your fuel mileage dropping some, and run a good fuel additive like Power Service or Stenadyne to help with lubricity. You don't have to worry about the taxman either, as you probably know if you're buying the stuff, by law Jet fuel can't have any dye in it, it's clear.

why not mix it with some filtered waste veg oil say 25/75 or 50/50
or mix it like dse says to 10%kero/5%rug

 

You would have no problem at all with it mixed with 20% biodiesel
