Number 1: Why Diesel Injector Sizing is Confusing
Diesel injector sizing can get confusing fast. Percent over, hole size, liters per minute (LPM)—what do these ratings actually tell you, and how do you know which injectors are right for your build? Lenny Reed from Dynomite Diesel Products joins us to break down the different ways diesel injectors are rated and why comparing injectors isn't always as straightforward as the numbers make it seem. We talk about what “percent over” actually means, flow ratings, injector sizing, and why choosing the right injector needs to match the horsepower goals and overall setup of your truck. Whether you're building a Cummins, Duramax, or Power Stroke, understanding injector sizing can help you make better decisions before spending money on your fuel system.

Number 3: This Muffler Lets Your Diesel Be Loud OR Quiet
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. Want an aggressive diesel exhaust when you’re getting on the throttle, but something quieter when cruising down the highway? We talk about how the adjustable muffler is designed to offer both, what’s changed with the latest version, and what they’ve learned from getting the product into the hands of diesel owners. We also get into the story behind Glory Days Speed Shop—from developing an idea and launching a new diesel product to growing the company and figuring out what comes next. If you like the sound of a straight-piped diesel but don’t necessarily want to live with it every mile, this episode is for you. Learn more about your ad choices. Visit megaphone.fm/adchoices

Number 4: Biodiesel is Already in Your Fuel - Why It Matters
Power Service joins us to talk about biodiesel and what diesel truck owners need to know about the fuel going into their tanks. Biodiesel can offer benefits, but it can also create new challenges for your diesel fuel system. 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.

Number 5: Cooling System Mistakes That Can Hurt Your Engine
Modern diesel engines generate a lot of heat, and keeping that heat under control puts a huge demand on the cooling system. But how often should you actually change your coolant, and what happens when you leave it in too long? Rislone joins us to talk about diesel cooling systems, proper coolant maintenance, and some of the common mistakes truck owners make. We discuss corrosion and contaminants that can build up over time, how coolant condition can affect heat transfer, best practices when changing coolant, and why maintaining the cooling system is so important on modern Cummins, Duramax, and Power Stroke engines.
