One other thing I learned today is that Avgas stays fresh for very long time in the can. It is designed to do that. Cargas on the other hand is only fresh for maybe two months. I also love the lack of smell...The down side according to Jim Martin is cleaning the plug every 20 hours of operation due to lead deposits. After all it is Low Lead, and not No Lead....But NO Lead has been mandated by the FAA and is coming. The designation is UL like 100UL

I don't like running the low end so lean just to make the engine run. Down to 1 turn open on LS needle. To get power you gotta have fuel, not to belabour the obvious.

The blended fuel experiment needs to be made simply to add to the knowledge base, but isn't practical for everyone.

As Todd says and recommends, 87 Octane regular gas is the best all around solution.
