One thing that has an influence on the lead contamination problem on spark plugs is power setting.
Cruising at lower RPM makes the problem worse than cruising at up near 5500 RPM

Thanks Scott, good info, I will try to use higher power settings when running the 100LL! I wanted to introduce myself at OSH but with OWW, you were always super busy. I went to the Van's banquet, but didn't want to disturb you. Hopefully say hello in Aurora some day, or at OSH next year!

Excellent report. Thank you for your insight.
This year was my first year to Osh in an RV-6 with an O-360.
Coming from Seattle, we got a little better TAS but your burn was incredible.
flying over the mountains and exploring our way across the Dakota's and Minnesota was incredible as we got to see country I've never seen before.
Congratulations on such incredible numbers in your 12. Thanks for sharing.

Hi Paul,

Thanks for putting this fun video together.

The more posts and videos I see lately on the RV-12 have me thinking that it is not just an inexpensive-Operating plane for fun/quick weekend flights, but it is also a pretty capable cross country machine.

Great write-up and video. It was a pleasure to meet you and Gary at the Gallagher social.

I just want to thank everyone for the very nice comments. It was really fun to see what our collective RV-12 can really do. I tend not to think of it as 'Light-Sport' anymore, it's a very capable 2-place GA airplane and it holds up very well in the low end of the Cessna/Cherokee crowd (especially when you start talking fuel burn!!)

Paul,

Great post and nice experience. With nearly 1000 hours on my Rotax 914 in my Europa, two comments come to mind:

After using 100LL, change not only oil and filter, but open the oil tank and clean it thoroughly. You'll be shocked at how much lead is deposited there.

Avoid 100LL!! It's been more than 5 years since I used 100LL! Use the website FlyUnleaded, http://www.flyunleaded.com/mapusairports.html
to find airports with Mogas (and send updates to flyunleaded to keep it up to date). AirNav also has some Mogas listings (and they accept updates too) and Swift lists the airports with their product on their website. We carry gas bags on board to enable us to purchase Mogas and take it to our Europa. When we can't find an airport with Mogas, we look for one near a major highway that has a courtesy car.
