This will be my first time to officially try my car at a track. It's only 1/8 mile & the elevation is like 4k. I am going to drive the 250 miles on June 9th (weather permitting)

OK here's a question, I want to up to 150 shot for the weekend but I am wondering about pump gas. I use 92 octane pump gas with the 100 shot without any probs. I am running stock timing/compression.

I have a line on some AVgas 100 LL from phillips 66. I believe the LL stands for Low Lead. I no longer run my stock 02's but I do run a Wide Band, will this gas screw up my wide band?

I have a recipe from this site for making your own gas which I would gladly do if it is a better choice. Not many options here in the middle of nowhere.

Which route should I go?
