 You're with Tom's Hot Shot Secret. We listen to our customers. Everyday Diesel Treatment delivers a 6-in-1 premium fuel treatment for every fill-up, every time. Our fans call it EDT. I'm Nathan from Ellisville, Mississippi, and I drive a 2017 Ford F-350 Power Stroke. I've been using Hot Shot Secret EDT every time for almost three years, and I've seen about one and a half to two miles per gallon increase.
