Ok it's a stupid question. I was thinking of the times when traveling and
one can get auto fuel and 100 LL at the same airport. If you mixed them,
you would be loading the engine with less lead. I realize one can use TCP
also to reduce the lead build-up. In the US, fields that have auto gas only
have 87 octane so it cannot be used in the 914.
