Has anyone had any experience with this on cars? I have on aluminum baseball bats. Cryo experts claim that it can improve performance of auto parts 3 to 5 times for wear. They claim that a Cryogenic motor can double your fuel mileage and last 600,000 to 1,000,000 miles. Many are doing brake rotors. Depending on costs, this is intriguing. I know that it makes a baseball travel about 20 ft farther, I would think it would have similar effects on an engine. It costs about $35 to Cryo a bat. If you could do an entire engine for less than $5000 and make it double it's life span, it would be worth it.
