Has anyone used Marvel Mystery Oil in their gas? I have used it in the past in other vehicles and noticed less knocking and chatter in the engine after running it for about 100 miles of so.

The mixture is 4oz to every 10 gallons of gas, so at 22.5 gallons for tank capacity of the avg. Trooper that works out to be about 9 oz per tank.

I would suggest that it be added about every 3rd-4th tank fill up as it work best from past experience at every 1500 to 2000 miles.

I haven't used it yet in my Trooper but am planning on adding it to my tank at next fill up and will report back if any changes, especially mpg changes after that.
