Its late and I don't feel like conducting a web search for an answer so I'm going to ask my fellow diesel owners a fuel question. I purchased a 2011 Chevy Silverado 3500HD 6.6L diesel in South Carolin...
You can use up to B-20. I use Standyne with every fill...but you will have to make that judgement on your own. Lots of opinions on that....BUT B-20 is listed in the manual as the max biofuel blend.

Some other diesel engines...older or other makes, will not run B20...but you can.
