My problem is the availability of 100 octane. I would have to fill up leaving the track and make sure I have enough to get back. Or keep a 5 gallon jug of 100 at the house like I do now. All my data for bracket racing is with a 1/4 tank of gas. So I usually get there empty and run a gallon at at time and add a few gallons to get home and park the car.
Now fast forward to this week. It has rained here quite a bit and my race last week was canceled. So I wasn't able to get gas. I had to take the car out to a few appts and didn't want to take the truck. I hate parking that anywhere I can't see it. I had to get at least half a tank, so I added 5 gallons of 91 octane. The highest octane choice we have around here. I was a little worried, but the car ran great. I put the stocks back on and went for a nice little cruise. No knocking and plenty of power. So now I'm thinking of keeping it and just mixing up 100 with 91 and see how it does. My good DA weather is gone for the season, so no records getting broken now.
