It is hard to find this stuff in Canada, but I did! I know this sounds crazy, but I am excited to put it in...Ok that did not sound rightShould I follow bottle instructions, or should I just add when I am a few hundred miles from my next oil change? Does anyone run this stuff ALL THE TIME IN EVERY TANK OF GAS? Where did you notice MORE improvement- fuel syst. or engine?

 

any more than once every 4 tanks would be a waste of money


once every three if you have a 38 gallon tank like me.


I wouldnt expect to see much difference other than a quieter engine on startup.

 

Quiter must mean less engine wear though...

 

Use both in the fuel tank and the crankcase. I would put it in the fuel tank about every 10 tanks or so. It helps keep the injectors lubricated.
