Diesel Additive for old Diesel Tractors

I couldn't find any Ag diesel last night so I had to buy some low sulphur for my old Ford loader. Is there an additive I should add to this "green diesel"? I've heard of people putting a quart of auto transmission to their fuel. Is this a good idea?
 
I'll be contrary, and say as long as it contains some biodiesel (2% soybean oil or the like) it will be fine.

The biodiesel replaces the lubricity that you lose from the lack of sulfur, and are good to go.

Biodiesel also is a bit of a solvent, and if you have an old tractor with a lot of gunk in the tank and fuel system, the bio will clean the system. In the long run that is a bonus. In the short run it might loosen up a lot of gunk and overload your filters and give you a bit of an issue..... The problem is your fuel system was dirty, the solution is the bio is cleaning it out; but that's not much comfort if you are sitting in the field with a plugged filter and none on the shelf to replace it.....

When I drove truck I'd put 3 or 4 qts. in a 60 gal tank once every month or so. Within 4 or 500 miles I'd feel an increase in power. It was a Mack ,Maxidyne' engine and it didn't need an 'inframe' for close to a million miles. I believe the high detergency in the ATF cleaned the top end and injectors resulting in more power, but I use Schaeffer's Diesel Treat and Nutra in my diesel tractor and pickup. Their products rate among the best for adding lubricity to [b:abc8c8abe2]U[/b:abc8c8abe2]ltra[b:abc8c8abe2]L[/b:abc8c8abe2]ow[b:abc8c8abe2]S[/b:abc8c8abe2]ulpher[b:abc8c8abe2]D[/b:abc8c8abe2]iesel that the feds now mandate but Power Service rates pretty well, also. Howes, 2-stroke oil and other stuff got a very poor rating as some actually decreased the lubricity and cetane rating of ULSD. Go to Wal-Mart or local co-op and get some Power-Service (white bottle) or Schaeffer's but use SOMETHING 'cause the older pumps and injectors won't take the ULSD crap.
 
(quoted from post at 13:25:09 05/01/15) Its all low sulpher Red or green/yellow. Just dyed red for offroad use.

ULTRA low sulphur diesel (<15ppm) You can buy anything but ULSD anywhere in US as far as I know.
 
I have a '63 Ford 2000D with 3700 orig. hours; no internal engine work. I put a little Power Services diesel additive in my tank when filling up at the local off road pump. Been doing it for as long as I can remember. Starts right up, runs fine, tugs hard.
 
The only difference with off road diesel is dye to mark it as not paying road tax. If you bought it at the same supplier it will be the same fuel.
 
Throw 10% or more kerosene in with it....at least you'll get some Sulphur for lubricant. and NO it won't melt the pistons.
 
ATF is excellent for a fuel treatment. ATF has an affinity for moisture and will remove water from the fuel system, as well it will lubricate the pump and it will add kenetic energy to the fuel , as will adding a quart of motor oil to a tank of diesel. I use ATF in the tractor fuel in the fall of the year as snowblowing season approaches. I have added a quart of oil and a can of fuel line deicer when the ATF wasn't within my reach..it won't hurt a thing and it has benefits .
 
Two cycle oil is one of the best things you can put in an old diesel's fuel to lubricate the pump at the rate of 1 OZ per 1 gal of diesel from all the studies I have read.

I think that you meant to say 'You [b:59ab1c2d52]can't[/b:59ab1c2d52] buy anything [b:59ab1c2d52]BUT [/b:59ab1c2d52]ULSD in the US as far as I know'. THAT statement would be true. I also agree with what Shaun said as that is exactly what I've been told by both of our local fuel suppliers. :roll:
 
You can buy all the snake oil you want, but in reality your 'ol low HP slow-running engine will be just fine without it.

Sorta like all the gas additives sold for cars.

Yea, like all the people who insist that premium grade or high octane fuel makes their engines run better or the octane additives. I made that statement for the engines/vehicles that do not recommend premium fuel, which most vehicles don't

Looked at an 8N a guy was selling (didn't buy it for other reasons) but he stated that he ran nothing but 91 octane premium fuel and lead substitute additives. Think of all the money he's wasted through the years on not only fuel but the additives.

With a good diesel fuel additive you get anti-gel in the winter, higher cetane numbers AND, most importantly in this era of low-lubricity USLD fuel, added lubricity for older engines whose injectors and injection pumps were not designed for, or manufactured with, materials to run long-term without a higher sulphur content. You are comparing 'apples-to-oranges' with the 8n story. AND, it's not always about ' Think of all the money he's wasted' ............ Maybe he could run a gear higher when plowing, or 1 mph faster on tractor 'runs' or maybe it just idled better OR maybe it just suited him. Who knows? Worrying about nickels and dimes gives me a headache :roll:
 

"the older pumps and injectors won't take the ULSD crap."

Can you provide ONE iota of verifiable proof of that?

There's a lot of older diesel tractors in use around here, I work on a lot of 'em, and visit a lot of farms, and I think you would be hard-pressed to find ANYONE adding lube to their diesel.

And I am NOT seeing IP and injector mass destruction.

Several friends run trucking businesses with a mix of older and newer trucks, and they don't bother either, except for anti-gell in the worst of winter.

I'll pass your info on to them, so they will realize the wrongs of their ways!

You said 'I'll pass your info on to them, so they will realize the wrongs of their ways!' to which I say 'Thank you' :eek: As far as providing 'verifiable proof' I don't believe that I could provide any info that you would accept. However, I'm basing my convictions on a pretty-much identical data-bank as yours - my own observations, information from truckers that I know, both owner-operators and line drivers, info from independent and corporate repair mechanics and what is being said on the web forums (DTR, etc.). There are a host of circumstances that could be different between your area and mine BUT it doesn't really make any difference as I believe what I believe and you believe what you believe so I'm calling it a day and wish you well. Adios' 8)

Been using Howells fuel in mine have pretty good luck with it.
Was using Bio until they change over to animal fat not a good thing filters plugged pretty often.
 

We have virtually no biodiesel here in NH. I add two stroke oil to my "old" ones at the rate of 1 oz./ gal. maybe there is not much evidence of accelerated wear with ULSD in old pumps, but I don't know that there has been much testing it either.
