Diesel Fuel Requirements
WARNING: This page does not describe the selected car, but rather 20 other vehicles, including the 1987 GMC Pickup, 1987 GMC Cab & Chassis, 1987 Chevrolet Pickup, 1987 Chevrolet Cab & Chassis, and 1986 GMC Pickup. However, it is still accessible from the selected car via links, so may be relevant.
CAUTION:
All diesel engines are to use Diesel Fuel #2 when the outside temperature is above 20°F (-7°C). In temperatures that are below 20°F (-7°C) use Diesel Fuel #1, this will reduce the chance of the fuel thickening and forming wax.
NOTE:
A Diesel Fuel #1 & #2 combination (Blended Fuel) may be used, and is recommended for mild winter driving.
