does any body out there feel the same as I in regaurds to the lurbicity in diesel going down hill every year?

Beating a dead horse here...

You need not worry about lubricity standards, ULSD WILL NOT harm your engine. Stop worrying and just drive.

I don't know, how are you measuring lubricity?

Diesel fuel has minimum lubricity standards that must be met by the refinery on every batch.

Don't worry about it.

I can't imagine the producers would try to reduce lubricity below the standards. Doing so would hurt their main consumers, the industrial users. Those folks have a lot of money and clout (imagine for one second, if all the truckers in the USA stopped driving for just one day in protest..).

Others jumpped in with ULSD=OK type replies. It might well be that the newer ULSD diesel formulation doesn't exceed the lubricity requirements, but merely meets it now. Since the producers would have been phasing in refineries that meet the new standards over the last few years, then yes, it could have been declining in recent years.

From the research I've done, biodiesel is better on the lubricity than ordinary diesel. A small percentage (maybe 5%?) blended in would probably fix the problem and replace some of the fossil fuel as an added bonus. I can't imagine there is anyone here on the forum that can't afford the extra $2 per fillup that'd cost -- the fluctuation in the price of diesel itself makes a bigger difference than that and I don't see anyone talking about not driving their car in summer because the cost of a fillup went up by $2.
