Can I get the quick rundown on using B10 or B20 in my truck? How do I ensure that it's quality bio? I found a Cowboy's truck stop that has it by my house and at $3. 38/gal I'm real tempted to use it. I'm behind the curve on the whole biodiesel scene, so anyone with the basics let me know. If it makes any difference, I have relocated my lift pump to the frame and I run 20oz of Powerservice in my truck. Thanks.
