We’re Seeing a lot of older vehicles in the shop as of late. These trucks sure bring back the memories. Although they lack the power from mechanical fuel systems (no computers) they are certainly reliable as all get out.
Since 1993 diesel fuel has gone under some significant changes, the most aggressive being in 2006 when this fuel needed to have a majority of the sulfur removed – Sulfur being a byproduct of diesel fuel, provided the lubrication for our pumps and injectors in the fuel system.
ULSD ultra low sulfur diesel fuel spawned a new era in diesel fuel additives. All of the manufacturers of these diesel fuel additives seems to “have the cure”, but the one thing they all seem to have in common is a lubricity additive.
If your truck is pre 2007 your truck NEEDS a fuel additive. If your truck is pre 1998 your truck REALLY NEEDS a fuel additive. Manual injection pump trucks were designed with sulfur in mind. Not having that sulfur in the ULSD that we use today can be very detrimental for your pump, injectors and truck in general. Manual injection pumps do not get better with age, without a lubricity additive the tight tolerances in the injection pump may be suffering, causing hard starts, lack of power, excessive smoke, poor fuel economy and the list goes on and on.
Although an expensive proposition; you may want to think about a freshening up of your fuel system, whether it is an overhaul of the pump, replacement or rebuild of injectors, even just having the timing set to verify proper operation, this may put some zip back in your trucks step. Be sure to protect the investment though with a good fuel additive.
Strictly Diesel has a very good variety of diesel fuel additives. We try to run them ourselves to see the benefits (or not) before they go on our shelves. Before you dump that additive in your tank, verify it is not good for both gas and diesel. Additives like this may contain alcohol, which will damage fuel injection systems.
Don’t forget to use a fuel additive on your new diesel truck as well. With injection pressures increasing on a yearly basis, the more lubrication you can give your fuel system, the longer you will go without expensive repairs.
