I got my fuel injectors flushed at Nissan. But their cleaner is made by Petro Chemical. I want to drop a can of BG44K in there since everyone is having such good results with that. How long do you think I should wait before doing this?

 

I use a bottle of Valvoline SynPower fuel system cleaner every 4-5k miles. I do the same with my wife's Explorer also. My 2k1 ZX6R gets half a bottle every 1500 miles.

 

1 bottle of Chevron Techron injector cleaner every oil change. Costco sells 4 bottles for $9.95.
