Has anybody used the Amsoil PI fuel treatment on their truck? Thoughts on it. Good product? Does it actually boost mpg and smooth out idle? Just curious. Not sure if there is another thread with this already discussed. Thanks.

No additive like that will truly boost MPGs... Keeping the engine cleaner will help with fuel efficiency, which leads to better MPGs.

It does look to be a pretty good cleaners, but I've always used Seafoam twice a year and it seems to work well enough for me.
