What is Additech and What does it do?

It will clean your engine by removing power-robbing carbon build up and increase gasoline mileage. A clean engine performs better and uses fuel more efficiently, resulting in more miles per gallon of gas. Super Mileage Booster is better than bottled additives because it is twice the concentration without the mess. Clean your engine today and start enjoying the benefits!

“I am a daily driver back and forth from Galveston to Houston. When I fill up on Sunday, I noticed that my mileage increases and I don’t have to fill up till Thursday. I also noticed a change in the way the engine runs when I use Additech. It runs a little smoother and not as rough as normal.”

“I have a 2008 Chevy Avao and it sat untouched for a year and a half. It was a typical old car that did not respond when I pushed the gas. I tried Additech at HEB and it was excellent. Additech really brought my car to life! Now when I step on the gas it feels like a race car and it jumps into action. I feel like the cars potential was unlocked. What I like about Additech is that it is at the pump and anyone can use it. Now I use Additech once a month and it makes a major difference. I refer Additech to all my insurance clients.”
