Avgas 100LL
•
Avgas 100/130
•
MOGAS with minimum Octane Rating of 95 RON

may be used.
•
Do not use fuel additives such as Octane Boosters.
NOTE
As there are significant variations possible even between automotive fuels with the same values
of RON, Jabiru Aircraft strongly recommend using AVGAS. Automotive fuels should only be
used where AVGAS is not available, and if used, must have the highest anti-detonation rating
practically available.
CAUTION
Fuel additives containing alcohol (i.e. Ethanol etc) will damage the sealant used in the fuel tanks.
DO NOT
use fuel with any level of added alcohol.
8.2 OIL
8.2.1
Engine Oil Specification:
Jabiru Aircraft approves lubricating oils of any brand name conforming to specifications MIL-L-
6082 for straight mineral oil and MIL-L-22851 for ashless dispersant oil.
Straight mineral oil must be used during the first 50 hours of operation for new and overhauled
engines, or until the oil consumption has stabilised. After the first 50 hours it is recommended
that ashless dispersant oil be used.
