Automotive Gasoline, Unleaded, Minimum
95 RON or 91 AKI
RON = Research Octane Number
MON = Motor Octane Number

Total Fuel Capacity:
Specifications: Europe - EN 228
USA - ASTM D4814
Canada –CAN/CGSB-3.5-94
(or more current issue)
20.1 US gal. (76 liters)
Usable Fuel:
19.5 US gal. (74 liters)
Unusable Fuel:
0.6 US gal. ( 2 liters)
CAUTION
Use of automotive gasoline containing alcohol (e.g.: methanol or
ethanol) other than specified in the above listed specifications, is not
permitted.
NOTE
Petroleum suppliers provide automotive gasoline of varying volatilities, depending on the
season and climatic zone. Fuels with higher volatility (“cold weather” grade fuels) are
more susceptible to fuel vapour formation than fuels with lower volatility (“hot weather”
grade fuels), at equal temperatures. Use of fuels dispensed in winter or in colder climatic
zones, under high ambient temperature conditions, increases the risk of vapor formation
and subsequent possible engine malfunction.

1.9. LUBRICANT AND COOLANT
1.9.1. Lubricant
Use only motor oil with API classification SF or SG or higher.
Due to high stresses in the reduction gears, a 4 stroke motorcycle oil of a registered brand with gear
additives that meets API classification SF or SG are highly recommended.
The viscosity should be selected according to the various climatic conditions using the following table.
CAUTION
Do not use aviation lubricant!
When operating with AVGAS100LL fuel do not use synthetic oil.
Oil Capacity: Minimum
: 3.0 liters (3.2 US qt.)
Maximum
: 3.4 liters (3.6 US qt.)
