Given today’s ultra-low sulfur diesel fuels, you may wish to consider using an additive like Howes Diesel Defender to get the most lubricity out of every gallon of diesel all the time, reduce potential downtime, and maximize your mileage. This can help protect the investment you or your company has in the truck, and can keep you from a trip-interrupting breakdown.
