Just need to think about the best route for sure. I mean 5gals at 400 bucks in the long run is cheaper but basically on par with Meth as well. So many options so little ability to TUNE this damn things. lol

How ever though Meth keeps valves looking new on this direct injection engines.
I didn't think a traditionally placed direct injector was able to clean both intake and exhaust but only one (believe it's intake). I admire Lexus' design where they have two per cylinder.
