BobZ Posted July 22, 2009 Share Posted July 22, 2009 I have heard that you should run through a tank of gas with fuel injector cleaner before you change the oil - any truth to that? Or is it safe to dump the injector cleaner in at anytime? Quote Link to comment Share on other sites More sharing options...
BCBird Posted July 23, 2009 Share Posted July 23, 2009 I use Motul injector cleaners every few months and the engine cleaner with oil changes. Sometimes I use Techron. Others use SeaFoam. Quote Link to comment Share on other sites More sharing options...
rodantking Posted July 23, 2009 Share Posted July 23, 2009 I would not say you can't use it any time, but I use it before a oil change. It helps to clean up the top end also and I figure that some of it is going to end up in the oil. Quote Link to comment Share on other sites More sharing options...
