Kohler KD62V12 Operation And Maintenance Manual

Maintenance
Lubricants and operating fluids
5.14.2 Approved diesel fuels, diesel exhaust fluids (DEF), and fuel addi‐
tives
All performance data provided by Kohler Co. are guaranteed only for an EN 590 compliant fuel,
with an LHV of 42.8 MJ/kg. Please apply correction factors when using a fuel with a different
LHV (Lower Heating Value).
Diesel fuels
Sulfur content and biodiesel content:
Only diesel fuels with a sulfur content lower than 1.5% (15000 ppm) are allowed in Kohler KD
diesel engines.
Information
For emission-certified engines (Tier 2, USA EPA CARB Tier 4 final, 97/68/EC Stage IIIA), only
ultra low sulfur diesel fuels (ULSD) with a sulfur content lower than 0.0015% (15 ppm) are
allowed in Kohler KD diesel engines.
Only diesel fuels with a biodiesel content lower than 10% are allowed in Kohler KD diesel
engines.
Winter operation (cold operation):
Most diesel fuels produce paraffin crystals at low ambient temperatures. These crystals
increase the flow resistance in the fuel filters and deteriorate the fuel feed to the diesel engine.
To prevent property damage, use only diesel fuels adequate to your ambient conditions. Pay a
particular attention in countries changing standard according to season. Filling the tank with
“summer fuel” may endanger your operability during winter.
The following fuels are approved for use in Kohler KD diesel engines. On request, other fuels
may be evaluated. Please contact your Kohler Co. representative before any use.
