OIL LEVEL
Check engine oil level:
At least once every 500 miles (800 km).
●
At every scheduled service interval.
●
NOTE
If engine uses more oil than normal or if vehicle is operated
under harsh conditions, check oil more frequently.
When checking or changing engine oil:
Warm vehicle to normal operating temperature.
●
Turn engine off.
●
Hold motorcycle upright (not leaning on side stand) on a
●
level surface.
1. Remove seat. See 2.40 SEAT.
2. See Figure 1-4. Remove filler cap/dipstick from oil tank.
Wipe dipstick clean.
3. Install filler cap onto oil tank. Make sure cap is fully
seated on tank.
CAUTION
Do not switch oil brands indiscriminately because some
oils interact chemically when mixed. Use of inferior oils
or non-detergent oils can damage the engine.
4. Remove filler cap again and check oil level on dipstick.
a. Oil level should be between upper (1) and lower (2)
dipstick level marks.
b. If oil level in tank is below lower mark of dipstick, add
oil to tank. Recommended viscosity depends upon
ambient temperature. See
sary to add oil and Harley-Davidson oil is not avail-
able, use an oil certified for diesel engines.
Acceptable diesel engine oil designations include
CE, CF, CF-4 and CG-4. The preferred viscosities
for the diesel engine oils, in descending order, are
20W-50, 15W-40 and 10W-40. At the first opportu-
nity, see a Buell dealer to change back to 100 per-
cent Harley-Davidson oil.
c. Install filler cap/dipstick.
