does anyone use 100LL av gas ?

100LL works fine in car engines. Used it for years in all sorts of engines. Not a single issue regardless of what naysayer speak of. So much BS surrounding the stuff. You'd think it was akin to putting a stick of dynamite inside a block.

Total horsecrap.

Quoted for the truth!

So many ignorant people regurgitating myths and wives tale about 100LL, you'd think the world would end if so much as a drop was burned in a lawn mower. I love the horse **** about how it only works at high altitude. Someone better tell the crop duster pilots that. Maybe the people that live in high altitude places like Denver can get by on it.
