There is no need for extra lubricity additives because the refineries are required to meet the lubricity requirments.
The ULSD lubricity standard in the US calls for a maximum wear scar of 520 microns. The lubricity additive is blended with the fuel at the terminals - not the refinery. This could something as simple as the delivey driver pouring the additive into the tank at the gas station. Europes ULSD lubricity requirement calls for a max wear scar of 460 microns. I'll keep using the additive as cheap insurance against low lubricity along with keeping the injectors clean.
Me as well. I like using additive for more than just the lubricity feature. Water is a killer in a diesel engine and there are good additives that, not only add lubricity, but help take care of any water in fuel, keep fuel system and injectors cleaner, prevent gelling in cold weather, and increase the cetane.
Unfortunately, a lot of stations do not tightly control the environment in which diesel is stored or, in the case of small "auto diesel" only type of operations, don't monitor the filters at the pump if they even have them installed. This is becomming more of an issue with even the heavy diesel engines. I can recall that one station I delivered fuel to regularly, had a problem with ground water getting into the tanks. I once removed 8" of water from one tank.
The above ground tanks suffer from constant heating/cooling and therefore a condensation problem if not monitored. Even the high volume truck stops encounter these issues. They are not frequent, but they do occur. Then there is alway the bacteria problem that can occur.
A good additive, such as Power Service or Howe's Lubricator, will usually keep these problems from being a real issue. They are cost effective and they work. Some think it is not necessary, and that is ok. I, on the other hand, find them good insurance in my farm equipment, semi's, and my CRD.
