Thoughts on this.....
Was talking with this guy selling his 2000 Chaparral (I know it's a family boat) and he was bragging about only using AV gas with a small mix of 2-cycle oil (for extra lube) He stated that Teague Marine said it was ok to do.
This seems like all down side to me especially for a bone stock small block, carbed mercruiser). 101 octane for a engine that needs only 89 not to mention the premix on the rings and in the carb. For what?

I can see the small amount of premix, kinda like Marvel mystery oil that some use. But I am talkin a small amount.
The hight octain, I would say no. There has been lots of talk in gear heads and just jets about it. Do a search if you wanna learn about it.

AV Gas is also formulated for aviation. It is less dense so it will be lighter in the planes and those engines have way lower rpm's. AVGas is freaquently used in engines requiring higher octane but usually if done right the engine is tuned to run on the stuff. If you were seriously thinking of buying it then research this stuff and maybe call Teague Marine to verify the story.
And what a dufus in the first place. 87 octane is cheaper than AVGAS so why else would you want to do this.

I would run it to clean the carb out every once in a while, but yes add a little mystery oil with it, no lub, lots of alcohol.

Stock motor!!!! He hurt it more than he helped it. low comp, motors will not burn AV gas all the way and make way less HP than just running 87/89. AV gas will work good in 11-1 or13-1 motors more than 13-1 you should run race gas 110 or +. he put 2cyl, oil to help lub the top end cuz AV gas runs dry. Thats why you run marvel oil 4oz per 10 gal is good. but in low comp, :rollside: like i said it wont burn good.
