The fuel island has #1 diesel used in frigid climates, #2 diesel the common diesel (and home heating oil) and jet fuel. What fuel is going to provide you the most power. Ill let this question go untill next sunday night. Chime in and good luck!

I'm guessing #2 diesel. Jet fuel may be really powerful, but I assume you're saying in a diesel engine. The engine is designed for diesel, and jet fuel could really hurt the engine. If #1 were the best, they'd use it everywhere, not just in cold climates.

It all has to do with BTU's....the higher the BTU's = more power...im not totally positive, but I believe it would be #2 diesel that would have more BTU's.

I would say #1 Diesel.
In early eighties while working at a transit agency we switched from #1 to #2 diesel. We experienced more smoke at first until we improved the tune up standards of the fleet.
My impression at the time why we changed was due to the cheaper cost of #2 diesel.

wrenchmen, yes, it is the BTU's and #2 diesel is correct only because it has more parafin than #1 diesel or jet fuel. They take parafin out of #1 diesel so that the lines don't clog up in cold climates. The other chemical in diesel that makes it burn hot,is sulphur.

the us navy uses jp5 jet fuel in all of the desiel engines used in forklifts,power generating equipment, tow tactors, fire trucks and other portable diesel operated equipment on thier aircraft carriers. when we took this equipment ashore we used no 2 diesel and te power was reduced. so i believe that jet fuel would provide the most power. a note: we had to add 1 quart of oil every time we filled the tanks because the jet fuel has very little lubricating quality.
most of these engines last longer than 10 years between overhaul(they run 24 hours a day 7 days week 7-8 months of the year.)i spent 20 years working on this equipment before moving to school buses 10 years ago.

I just got back from my Guard training. The Army uses JP in the tanks, etc.

Actualy Sulfer is used for lubracation. That's why manufactures are not liking the low sulfer standards. It does add some power. But it's mainly a lubracator.
We use both in our fleet. We switch over in Late Oct and switch back in mid March. The lighter Fuel #1 has more power. But has less additives to help lubracate the engine. This will cause it to run hotter and gain some power. But it has a drawback. It's not as good for the engine.
#2 deisel has more lubracants and this is the reason why it "gels up" at low temps. But it is safer for the engine.
Jet Fuel on the other hand has almost no lubracants. It doesn't lubracate anything so it isn't needed. I would NOT recomend running Jet Fuel in diesel engines.
It's kinda like running White Fuel in the engines. Most people know White Fuel as Karosine. You can run it but because it doesn't have the lubracants needed you must add a lubracant. Some people will know that you can add a quart of transmition fluid for every 15 gallons of karosine.
Just thought I would throw that extra info in there.
More Power=Jet Fuel
More Power from Diesel Fuel=#1
Safer for the engine=#2

Wolf, Had you ever thought about using and additive package in your fuel to add lubricity to it whit out using sulfer?

We Usualy don't add anything to our fuel. Only Anti Gel agents on really cold days. We go threw too much of it and it would get costly. Low sulfer diesel here is extremly expencive. So we just get what we can afford and with a $1.8 million fuel budget each year, we can't really afford much more.

Wolf, my additives come from HYDOTEX, thier based in Dallas, Texas. Ph. 1-214-638-7400. Give them a call for technical information on your cold climate problems and maybe they can help. I know in my district, it helped alot and I use their product in all my fuels (gasoline and diesel) and my all of my engine oils. They also have a great transmission fluid for all your automatics. longer change intervals.

What? You are sposed to change Transmission fluids? :) We tried doing the "service" thing but all it did was make the trannys slip and it resaulted in a transmission overhaul anyways. We even tried to move the service milage up some but it didn't make a difference. So now we just let them go and when they get overhauled they are replaced with Jasper Transmissions. They have a "So called" Full lifetime warrenty. So we really don't do any servicing anymore. WE do however check fluids on a regular bassis.
We never had a problem with gelling. Only a couple times when the weather suprized us and our suplyer didn't change over in time we had a couple gel up but we just changed the filter and all was good. But thanks for the info. I might have to check it out.

SBB, lucky(but smart)guess! Wrench and Rock, right on!
BTU's!
Grade 2-D diesel fuel 137,000 BTU/Gal. -5 pour point.
Grade 1-D diesel fuel 133,000 BTU/Gal. -30 pour point.
Jet Fuel 122,000 BTU/Gal. -50 pour point.
Kerosene 120,000 BTU/Gal. -50 pour point.
I never actually tested it, I am suprised to see that wsauer had seen an improvement in performance, I have to declair him a winner also!
All rules apply from first trivia question. This weeks prizes are "experienced" headlight bezels from IH Loadstars with fiberglass hoods! Congradulations to last weeks winner Bob, he claimed his prize!

I know this is old tho...
Jet Fuel can be used in diesel engines, if the engine is tuned right, and wont hurt anything.
Both grades of diesel wouldnt give you either more or less power; it would be almost unnoticeable.
