Yes folks, my diesel TV is going on LSD uh correct term is USLD (Ultra Low Sulfur Diesel) beginning in June. I just returned from a Fleet Maintenance meeting at our home office in which they presented some issues we are facing not only with our current diesel engines but trucks ordered in 07 with the new redesigned diesel engines. We have conducted our own test on the USLD and found that with the lower sulfur content the BTU's of the fuel was 2% lower to which translates into lower horsepower. Our test units also shown a 4% decrease in MPG - some attributed to the driver trying to get back some of the lost horsepower. Now the big issue revolves around the intergrety of the fuel provider. It seems that sulfur provides Lubricity in which the engine needs or test have shown engine failures if a replacement of that lubricity is not put in the fuel. The refineries cannot put the additive in as it would contaminate fuel in the pipeline also used by jet fuel. So the additive will have to be added to the tanker prior to bulk delivery to the filling station. Problem is there is no test equipment to determine if the right amount of additive is being added and we have found that this is two differnt types of additive - one is expensive and works the best another is cheaper and barely meets the minimum. So which will the gas station put in his tanks - we don't know. By the way, they also told us to be prepared to change fuel filters more frequently as this new LSD fuel will be clogging fuel filters more often.
Bottom line - don't expect any drop in diesel fuel prices - be prepared to pay even more.
Does anybody out there in Monty land know of a good additive to get from what is currently on the market????
