Maybe I've been lucky but using it with no ill effects since '93 can't be all luck.
I'm glad that your experiences are positive. It seems like you are on top of your maintenance and modifications. For me, I have found other options that I trust, and in the long run don't cost me much more. Actually, they cost me about the same because I'm not topping off down the road.
