I think it's around 7500 ft. MSL. Why? Well, car gas will start to vapor lock at higher altitudes so you have to watch this." He goes on to say that if we're flying about 7500 ft MSL we should use 100LL which has a lower vapor pressure than auto gas. Anyone heard of this? Had this happen? I know I'll be flying above 7500 MSL on my flight to Florida and am curious if any of you other two-strokers have ever experienced this or heard of it.
