First, I’ve been away for 2 weeks in the Caribbean, so just catching up … some interesting reading about the staging and injector lag issue by Steve Boese.
And Mark, my math (75 G * 4 qts / 2 qts) says you are mixing at 150:1 … seems a bit light.
Perhaps I’m mixing too strong 22 L / .2 L = 110:1, one Gerry can at t time.

Bill,
One quart = 32 oz. So I added a little over 2 qts (1 qt./tank) along with 75 gal. of fuel (37 gal/tank). As I figure, that is approx. 1 oz/gal. That is the ratio of oil/fuel I've always used.
As for switching from mogas, I switched because a year ago the %$#@%&^ government bureaucrats mandated that all gas stations in Texas switch to 10% ethanol for all grades of fuel. As I've heard from others on the Lancair list, ethanol will attack and soften the adhesive used to bond the wings together. When that happens the tanks will begin to leak, or worse. I've searched and searched for non-ethanol mogas in my area and the closest that I could find is at a marina about 75 miles away from where I live, or 125 miles from where I keep the airplane... not a workable solution. So, for now, I'm stuck with 100LL. The engine runs fine on 100LL and it doesn't mess with the integrity of the wings. It just costs me an extra $100 to fill 'er up. I try not to think about it.
