WEll I've actually am 100% sure they are not stealing it because I've already got an locking gas tank. But anyway the oil only smells a little like gas I had to get someone else's opinion just for that small amount because I could'nt even tell If It did or didnt.This is what I know It has trouble starting sometimes when its hot, it seems to be using alot gas and I cant find a leak anywhere now im trying to find a way to put it on a pessure test but any info is greatly apreshated!
