0.00 30 minutes The thought of paying over $4.00 for diesel fuel has Ian and Jessi seeking a "green" alternative! The solution? We brew our own Biodiesel right in the Xtreme shop, showing viewers how they can save money, and do their part to help the environment at the same time. We'll take you through the entire process step by step. And in our event of the week, we go to one of the most xtreme events ever in Johnson Valley, California and their 50 mile rock / desert race known as "King of the Hammers".
