Amazing Products and Great Service

★★★★★

"I’ve used all types of oil additives, but this is the best I’ve ever seen. Immediately seen my oil pressure go back to where it’s supposed to be (from 30 pds to 40 pds of pressure) and blow by almost entirely went away. No other additives have done this."

"Been using EDT in my 2018 Ram 2500 w/6.7 Cummins since 1000 miles. Once in a while I’ll fill up without adding EDT, and I can feel the difference. It’s more “peppy” with it. Better throttle response. I’ve also never had a “drain water from separator” message in 29k miles. I’ll continue to use it as long as I have a diesel!"

"I purchased the FR3 for my Harley FLTRXS after having good results from Hot Shot’s EDT in my pickup truck. Works great, idles more quietly and picked up a solid 1 – 2 mpg. Will start using it in the daily driver also.”

“Five stars for Gasoline Extreme. Cleaned up a 3.4 V6 Toyota. Now it has the performance of a new engine. The idle is so quiet that I had to turn up my hearing aids to make sure it was running. Great product! Keep them (new products) coming.”

“They have top-of-the-line products; we have top of the line race cars. We worked together on the Adrenaline racing line that has now shown real-world results.”
