Has anyone tried putting this in their gas tank? I've been putting 2 ounces in my gas every other fill up, just opened my second bottle. Right away my engine started running smoother and quieter and overall response has improved. They claim it will improve gas mileage but I haven't notice any change except mpg is steady. Haven't tried his in my oil yet and it is supposed to improve gas mileage and clean your engine.

Thanks for the pics. Never seen this before, it must be new. I've used the original MMO on Gas and oil. Didn't cause an issue, but I really didn't have a problem that I needed to fix.
