im really just guessing, kinda just pour some in and whatever goes in, goes in. 1-2oz per tank is better than 0oz per tank in my opinion, it has to at least be doing something.
when i had my intectors out recently, they were immaculately clean, as were the valves too, nothing but bare metal, i was quite impressed to say the least.
im very fond of MMO, every time i talk about it i just want to add more. after seeing how immaculately clean my engine internals are with 121,000 miles, i must be doing something right.
