Conventional diesel is rolling back on its heels. Proponents say that there are two types of fleets today—those that are planning a switch from diesel or those that have already made the move.
That is a small exaggeration, but concerns surrounding cost, emissions and Diesel Particulate Filter (DPF) maintenance are forcing fleets to look in all directions for solutions: Renewable diesel, propane, natural gas, electric drivetrains and even gasoline. Though propane has enjoyed a certain advantage over the other alternatives because of a unique combination of maintenance, emissions and cost saving benefits, its dominance was challenged with the arrival of renewable diesel.
