ULSD query
 

Was it ever decided for sure that ULSD would have lubricity agents added from the refinery so our 20 year-old injection pumps get the lube they need? Are we running ULSD as of yet in the States? Does Power Service have lube agents? Redline Catalyst? Lubro-Moly Hi-Test?

BP Amoco claims that their ULSD (which, IIRC, is the only ULSD sold in the US right now, and only in a few areas) contains enough lubricity additive to return the fuel's lubricity to 'standard' levels, though the standard levels of most #2 is still below the Engine Manufacturer Association's recommendations.

As little as 2% biodiesel (B2) has been shown to restore the full lubricity of ULSD fuel with no other additives, and is cheaper than any other additive. :)

I tried the ULSD from Arco/BP and it works fine although I only ran 1.5 tankfuls through here in California. Here's a tidbit of the seemingly cryptic tech info that they claim. I am not sure if anyone has done any scientific tests with the Bosch pumps.

"Controlled Lubricity ensuring it does not drop lower than 3100 grams, on the SLBOCLE (Scuffing Load Ball on Cylinder Lubricity Evaluator) test, which is the level required by engine manufacturers in their engine warranties. As sulfur is a natural lubricant its removal can have adverse effects on engine performance. BP uses a specially formulated lubricity additive to ensure the lubricity level remains higher than 3100 grams."

Here's some stuff that a search of the forum revealed:

lubricity, here is lubricity
 

i spent some time tonite with a fella who sells b100 in this area, actually he is distributing iowa virgin soydiesel. at 3.50 gal he is not selling much but is offering the b100 in quart plastic bottles. just the thing to get that b1 or b2 blend into a tank. he is looking to maybe sell cases. look him up at
www.armcoenergy.com

What is "iowa virgin soydiesel"? Does that mean straight soybean oil, or has he processed it into biodiesel?

You can buy pure soybean oil from Smart & Final in 5 gal. jugs for about $13, or just over $2.50/gal. And they just had a newspaper insert $5 off coupon on purchases over $25 good through Jan. 30. So that would bring the price down to around $2/gal if you buy two jugs. It will last you for 10 tanks if you add a gallon per tank, creating basically a nice B5 blend. That's what I'm doing currently :cool:

That blend would not be "B5" or "B" anything. "B" stand for biodiesel, very different than SVO. The soydiesel mentioned is Biodiesel (NOT straight vegetable oil), or rather, transesterified veggie oil (thinned by chemical removal/replacement of the glycerol in the veggie oil.)

With that said, you CAN just dump in plain soybean oil, but it will RAISE the CFPP/Gel point of the fuel MUCH more than Biodiesel.

The $'s quoted for the soydiesel is about right for current nationwide B100 pricing. Many studies have found that 2% Biodiesel (NOT just straight veggie oil) raises the lubricity (BB tests) over 30% ABOVE that of normal sulphur diesel (pre-ULSD levels.)

So the guy re-packaging in one-quart containers is a good idea, but the cost will be up there just because of packaging.

I'd suggest saving one-quart plastic containers (motor oil, dried-out empty water bottles, etc.) and buy 5gals of B100, then split it into the one-quart containers and keep in the trunk for every fill. WAYYYY cheaper than ANY additive on the market and will increase lubricity and cetane.
