I have no experience with avgas and have only heard rumors about how to use it properly. I just bought a 2.0 subaru motor that has been tuned running it and I dont want to pay the $750 to reprogram it especially with how great it runs on it now (269 rwhp). I have heard to put an oil cap full of marvel mystery oil or trans fluid in each 5 gallons for lubrication. Is this true? Anything else I should know about it?

In a nutshell .... There's much more to the story but for now that's enough of my opinion.
