Has anyone heard about a new low (or lower) sulphur fuel thats coming out this fall?
Will it affect the o-rings and pump seals like when the fuel changed back in the early 90's?
I think its supposed to have a great deal less sulpur and produce less emissions but do the seals need this for lubrication?
All this has me worried.
 
There are a variety of additives which can compensate for the lower lubricity of low sulfur fuel. The least expensive is pure canola oil; 2% gives all the lubricity required. There are also a wide variety of specialized diesel lubricity additives at much higher cost.

I believe that Saskdiesel is referring to the new standard ultra-low sulfur diesel (even lower than now) which is legislated to come in at the end of 2006. This will adopt a similar diesel fuel to European standards (I believe).

The good news is that Toyota, Honda, Nissan, GM, Ford, and a bunch of others are all planning to bring diesel vehicles to N. America because they will be finally able to sell them in California.

That being said, all you said about additives in low-sulfur diesel are true, so the same advice you gave still applies.

I noticed some new "low sulpher" stickers at the pump the last time I filled up. Turns out the owner had just gotten around to putting them on.
 
It is my understanding that the new Ultra Low Sunfur Diesel coming out this fall will have significantly lower sunfur content than current fuel - somewhere in the neighborhood of 7 PPM, if I am not mistaken.

The hydrotreating process that removes the sulphur also reduces the level of lubricating properties of the diesel as we have edperienced in the 90's. It will be moreso with this new ULSD. To counteract this problem, the manufacturers intend to introduce lubricating additives into the fuel at the refinery. Whether this will be as good as the old diesel, pre low sulfer, or even as good as the current stuff, remains to be seen.

Also another aspect of this ULSD is that it has less energy in a specific volume than current diesel. Although this will probably not be noticeable to the average user, one might experience mildly reduced fuel mileage (perhaps 1-2 MPG). One could likely introduce their own additive with cetane such as Stanadyne's performance formula or others to counteract this. This would also add additional lubrcants which may or may not be required.

There is an article in one of the off road magazines that covers all this stuff. I don't remember which one as I was just reading it about a week or so ago in the grocery store.

In oz the low sulpher fuel mainly seems to affect the Nippondenso 6 cyl rotary pumps such as that found on the 1HZ/HDT
Inline pumps are unaffected according to the diesel shop that rebuilt my pump.

One mechanic said some auto trans fluid in wth the fuel will help but he was unsure how much.
We can buy diesel with 20% bio diesel blend,maybe this will help
 
all the additives IMOP are similar....how do we know any different? I can't feel any difference from regular diesel un spiked... The differences are only going to be felt when the pump fails.

I find using the additives makes us feel better :) But I can't feel an operators difference. So how do I know if Stanadyne or canadian tire brand are any different? Unless you are a chemist. They are all the same.
 
ULSD is one of the reasons I use biodiesel. I add bioD in all my vehicles for increase the lubricity. On my newer vehicles (my wife's), we run it straight. On my older vehicles, I run about a B25 blend and will eventually change out all my fuel lines to Viton fluorelastomer as well as the O-rings in the pump. Once that is done, I'll be running at least B50 across the board.

BioD helps a LOT when it comes to lubricity.
 
"We can buy diesel with 20% bio diesel blend,maybe this will help"

Of course it will, a small percent of either biodiesel or vegetable oil provides all the lubricity required.
 
I just think whatever you use, always put it in every tank, and use the same stuff as much as possible.

you really can't use too much, just giver.

I hope toyota brings some real land cruisers to canada, I saw an FJ Cruiser the other day and the guy driving it almost crashed checking out my truck, I gave it a quick glance rolled my eyes, and I think he was jealous!

lol, of cousre thats just me.

I'm no chemist, but I can perform simple arithmetic. My fuel consumption went down immediately on the first tank that I put the Canadian Lube Corp's additive in. It went from 12.4L/100 kms mixed city/hwy driving to 11.8L/100 kms. On the third tank, it has gone down further to 11.1L/100 kms mixed city/hwy driving. I'd say that's a significant gain.

I also notice less smoke out the tailpipe, and it seems to have a little bit more power.
 
Well then I can continue my search for an 81 series then.
As long as I can keep the pump alive thats the main concern. A little less economy won't bother me so much.
 
The ULSD will be out this October. It already has a lubricity additive. That was part of the deal. The fuel companies have spent like 6 billion dollars converting your refineries over to ULSD. You have nothing to worry about. The cetane rating will be way higher than it is now too.

Thanks for the info, Tom! :beer:
 
Roger. Ill try and post where I found that....
 
Hey Stone,

Where did you pickup the Premium Diesel additive?

Thanks,

Wes

Howes Diesel Treat (available at Lordco) has been a good additive for me in the past. I am now trying Canadian Lube Corp's Premium Diesel treatment from Piers Diesel Research and I've been very happy with it so far.
