of the ftrewall. It is accessible by removing the lower cowling. After
cleaning, a small amount of grease applied to the gasket will facili-
tate reassembly.
(b) Fuel Requirements (AVGAS ONLY)
Aviation grade fuel with a minimum octane of
100/130
is
specifted for this airplane. Since the use of lower grades can cause
serious engine damage in a short period of time, the engine warranty
is invalidated by the use of lower octanes. Refer to latest issue of
Lycoming Service Instruction 1070 for approved alternate grade
fuels.
Whenever 100 or lOOLL grade fuel is not available, commercial
grade 100/130 should be used. (See Fuel Grade Comparison Chart).
Refer to the latest issue of Lycoming Service Instruction No. 1070
(Avco Lycoming Specifted Fuels).
A summary of the current grades as well as the previous fuel
designations is shown in the following chart:
