I would say every fourth tank is too often to run cleaner in ur tank. What kind of gas do u use as in what brand?If u use the top tier gas then ur injectors should be pretty clean. Like unocal 76 chevron shell texaco but I would use the cleaner like every 15k if u wanted to run some thru and I would use the chevron techron stuff its expensive but works great I think they sell it at costco in like a four pack even. If u use top tier gas then u dont really need that professionial cleaning unless u had alot miles on ur vechile and were using non top tier gas.
