   Glory Days Speed Shop is back on The Diesel Podcast to talk about the latest updates to the Thunder Muzzle and the idea behind giving diesel truck owners control over their exhaust sound.

   Power Service joins us to talk about biodiesel and what diesel truck owners need to know about the fuel going into their tanks.

We discuss how biodiesel can contribute to microbial growth, fuel contamination, storage issues, and additional maintenance concerns that truck owners may not realize are happening inside the tank. We also cover what biodiesel blends mean for modern diesel engines, how fuel quality can affect filters and other fuel system components, and what owners can do to help prevent fuel-related problems.
