[HI Cobra]

Great price! In my 351 Windsor in Hawaii I run 1 gallon of 110 AVgas per 10
gallons of premium (92 oct here) and it makes a big difference in how the
engine runs - really noticeable in 5th. Before using it I had to downshift to 4th
to go up H-3 to the tunnel, now it pulls just fine in 5th, for example.

Some of you there might try that, add a gallon or two to the tank and check it out. I tried it once early on with mostly Avgas but it wasn't any different than
it is with the 1 in 10 ration, and at $6/gallon I don't mind thinning it out. Also got about 2 to 3 more mpg so cost wise it is about break even but with much better performance. At about 10:1 c/r it seems more isn't better.
