... its been a while since I read that memo , The HFRR 460 is not the fuel standard, it is one of the tests used so that ASTM can make the standard, Its called scratch testing, the SLBOCLE the other method is called the scuff test, All the reports I see use the HFRR 460/ scratch method...and I don't know why?... But I will ask, Very good point on the use of a fuel lubricity additive for the first fill on new Diesels for the Break in of the fuel system if the engine has not been test run and broken in before shipment, some OEMs do it and some don't, You will know if you have to run special lube oil in the crank case for a period of time than a fuel additive is also recommended and is the responsibility of the end user to comply with the brake in procedure. It should be provided in the warranty paper work with a new engine, Very often this is the responsibility of the engine installer. It has been a few years scince I have sold new Diesels and fuel injection equipment so I am not up to date on who's doing what now.
The issue of adding a fuel lubricity product to your fuel tank is some what dependent on where you live, I can only talk about Atlantic east coast cause that's the bulk of the fuels we sample and test, The EMA < eng mans assoc > have a lubricity standard called HFRR, The min # is 460 HFRR, The good old high sulfur pre 2005 fuels were Diesel #2 350/390 HFRR Those days are gone, The low sulfur we have seen after 2005 has been 390/500 HFRR and now for Ultra low sulfur 600/800 HFRRWe recommend for long term storage tanks should be empty and cleaned before use, Good topic fellas
, I am glad that everything is working fine, It was a pleasure working with you and Bess last summer, As for the part where I stay up @ the truck & watch the pressures well... that's not completely true... Jed does talk a lot and after a while I just need the space 
I suppose that's a small price cause Jed does get the Lions share of the nasty work. last Friday Jed had to do a confined space entry for the Feds around 30 ft into a long rectangular tank, He was talking thru his respirator non stop for 30 mins At least I know he hasn't passed out . I stumbled on this site last night while searching for a fuel additive and started reading some posts, This seems like fun.
That's a great link, thank you. I've been using Opti-Lube for a few years and couldn't tell you whether it has done anything, but the study is interesting because it shows some larger name brands actually making lubricity worse. Caveat Emptor, I guess.
Now there is an unbiased article!
One of the data points from that particular study I thought intriguing is that Val-Tech makes a product, and presumably sells their fuel with that product, that increases wear.
Such a deal.
Extreme care and a basic working knowledge of the chemicals and the reactions from the mixing of chemicals should be known to the end user,< not so easy to figure out> protective gloves and good ventilation are mandatory even @ simple fuel filter changes, One should read or have a copy of the MSDA sheets for the fuel products purchased, You can down load them off the net for free, For boats with a open bilge system < non water tight compartments > Fuel in the bilge from engine room leaks flowing into sleeping areas is potentially hazardous to your health and should be avoided, Rent a room and vent the boat, And last thought... tell your fuel maintenance guy what chemicals you have added or if you bought fuel like Valv Tect so he wont get sick also
You can add another then. I also am aware of the so-called traditional wisdom, (interestingly even perpetuated by people who you would think would know, like PMM's Steve D'Antonio), but have never experienced it in my tanks, even though I drain the bottom of the separator in the primary filter just to check, especially after a new fill in case I got bad diesel. I have never drained more than a thimble-full of water, and I never have my tanks more than half full, winter or summer. With the levels of humidity we can get here in Queensland, I would expect it to happen if it was a significant issue, especially as we can have wide temperature excursions between night and day..Oh well, two more that agree.......
EVERYONE that I know or have read about that has ACTUALLY CHECKED for water in partially full tanks (or even empty) has never found but a very small amount....
Thannks...it won't help some understand...but for some it may mean the difference some day of making smarter choices.
