Every 10 hours
- Check the engine oil and change if it rises above the maximum fill level
- Inspect the fuel system components and replace as necessary
Half of original interval
- Change the engine oil and filter
- Replace the fuel filter(s)
Every year, regardless of operating hours
- Change the engine oil and filter
- Clean the fuel tank
Effects of biodiesel on engine oil
Using biodiesel can lead to increased oil dilution.
Use engine oil analysis tools frequently to check for
fuel dilution and monitor engine oil condition. Check
the engine oil level daily. Always change the engine
oil if the oil level rises above the maximum fill level.
Effects of biodiesel on fuel systems
Biodiesel dissolves and loosens some fuel system
deposits. During the initial conversion to biodiesel,
loosened deposits will travel to the fuel filters and
require more frequent fuel filter replacements. Start
with new fuel filters when using biodiesel for the first
time.
Biodiesel is aggressive to some materials used in
fuel system components. Inspect seals, hoses,
rubber and plastic components every 10 hours.
Repair or replace any components that are
damaged, softened or leaking. Clean biodiesel from
painted surfaces immediately to prevent paint
damage.
Biodiesel is more sensitive to bacteria and water
contamination than distillate diesel fuel.
- Use as much fuel as possible before refilling the
fuel tank in order to prevent bacteria growth if a
machine is in regular use, e.g. regularlly uses up
a tank of fuel within a week. In climates where
condensation is a risk, or when the machine is
working for short durations, keep the fuel tank full.
- Do not use biodiesel in machines with low
utilization or operating time.
- Do not store machines for more than 4 weeks
without flushing biodiesel out of the fuel system
by operating the machine through at least one full
tank of distillate diesel fuel.
