exalant stuff. I use it in a fleet of equipment. When I had started using it the engines had few oil changes done and I started a PM program and added that to the arsenal.
Took a year of use and oil changes are like gold now. This also repowered three engines that were on there last leg. I feel it is well worth the use.

I only use this in fuel and at oil changes. I add 2oz's to the oil let the engine run for 20 min., drain oil and change filter.
Fuel is one pint to a tank of gas or diesel once a month. (my personal vehicals too).
Through out the summer I add it to our 250gal. bulk tanks so all the equipment gets it run through the fuel system.
I wouldnt use it through the vacume ports unless you feel carbon is a big problem. running it through the fuel will do the same thing.
