I have no way of validating their test. However, I think the reasons for the test are valid, as evidenced by the reports from the fuel systems manufacturers. Today's ULSD fuel is different from the past, with less inherent lubricity as a result of the refining needed to remove almost all the sulfur.
My concern is this: the ULSD delivered from the refinery has insufficient lubricity. To remedy this, each jobber adds the amount of "stuff" needed to increase lubricity to US standards. US standards are below what the fuel system manufacturers say are needed.
Problems:
1. US standards are too low.
2. We depend on the fuel jobber to add the "stuff" needed to bring the ULSD up to US standards. The guy who actually adds the "stuff" is a jobber's employee of some sort, sometimes the truck driver himself. I would "hope" this guy is diligent in adding what he is supposed to add each and every truckload.
Unlike some politicians, I don't consider "hope" to be a plan, so it makes me uneasy to think about it.
As a result, I do use additives as cheap insurance against a potentially expensive problem.
