Too much octane can actually ruin an engine. The lack of combustibility can lead to large amounts of raw, unburned fuel moving around in the cylinder. That fuel can do things like lift rings and cause them to break also resulting in uneven cylinder wear, it washes oil and tears up the rings, pistons and walls, gets into the crankcase and dilutes the oil so on and so forth.

You basically pass fuel through the engine that can't burn, and gets everywhere in the process.

I knew that before I put it in there but, I didn't figure 4 gallons would do it.

Did you run it straight? if so thats where you went wrong! I`ve ran avgas 100 LL, 105,110,118, and havent ever had an issue!
The best by far is the 100LL!

My tank was pretty close to empty. Only reason I ran it out was to make sure I wasn't on the dyno with it and then filling up with 93 octane with an ethanol mix. I believe this was 114. It was very expensive, that is for sure.
