What do you want it to do in your Jeep?
Why do you think you need it? What are you trying to accomplish?
Do you want to run it in your gas tank or oil crankcase or both?
My thoughts....I use it in my gas tank everynow and then to keep the system clean and it also promotes keeping o-rings in good shape.
In the crank case...in modern engines...not needed and when you add this product you are really thinning out your motor oil..I just don't see why adding a bunch of additives to your motor oil helps, when you run a 10W30 or 5W30 then add something to raise or lower the viscosity of the product, why not just run a different weight to start with...?
