Mogas

Post by Buhwana »

'Bob,
Why would one need a STC for Mo-gas? My manuals state to use aviation
grade 73-87 octane as does the sticker on the wing, not 100LL so if
I use 100LL am I disregarding the manual? is it better to use mogas 87
octane (or higher) or aviation grade 100L?. Seems like either choice
is illegal according to the manual. I run one tank of mogas and one of
100LL. My mogas doesn't have alcohol and all my flying is below 3000'.

Hey John great to hear from you, I think you will find that the
STC is for the engine only, and only

In an F 24 type airframe. No any other certified airframe such as a
Widgeon
or M 62 has a STC. I have

used 92-93 octane rated mo-gas in various Ranger engines for the last 20
years and I have not had to buy a

spark plug since. As I recall two STC's are required, a power plant
and an
airframe. Bob Haas.

'Tom, you have a good point! Actually after all these years I
have never been challenged by

The Fed. I think in the back of my mind I'm concerned by the potential
accident review board.



There are no PT's in Trade A Plane last issue. I think I'll try
Barnstormers in January. I guess

you still have the Old Grey Fox? The high pressure system here in S.W.
Florida is fantastic for an

open cockpit, when I'm around 2500 I can see Naples to Sarasota, and I
wonder why I want to

sell. Bob Haas.
