Storing fuel for a day of racing

1

What is the optimal way of keeping your unmixed fuel on a race day?

I mix fuel as I need it over the course of a race day. Is a steel jerry can better than plastic or is the difference negligible over the course of only 1 day? I’ve been caught out once or twice with my fuel in the sun for 5-10 minutes in a plastic container and I’ve read sunlight can kill the octane level in fuel. I’ve seen people with mirror/reflective padding wrapped around their kart tanks as well.

In one day I don’t think you will have any issues. The concern is more about temperature. Cold gas performs better than warm gas. Keep the fuel in the shade. I believe air would likely be your next enemy, so keeping it in a closed container is better than an open container.
