Episode Notes

This is the 75th episode (S06E01). Welcome to the season 6 premiere! We have an exciting season planned for you! We have a new 3D animated intro (we’ve gone from the F-150 to a Mustang), along with other new motion graphics for the show!

In this 75th episode, Chris tells you everything you ever wanted to know about diesel engines. For the past 5 seasons we haven’t talked about them, and we’re making up for it by devoting an entire episode to them! Chris talks about how diesel engines work compared to gas engines, maintenance tips, the different types of diesel fuel that exist, and of course various aftermarket products that can improve your diesel engine’s performance.

This episode features our regular segments, Letterz and Partz.

In Letterz, Chris answers viewer mail and shows you the newest member of the Letterz set, a custom-painted Motorz/Craftsman guitar from Milestone Paint & Body! In Partz, Chris shows you some really cool ratcheting clamps from Craftsman, how to keep your garage cool during the hot summer using a Port-A-Cool Cyclone 3000, and how to keep everything tied down in the bed of your truck using AMP Research’s tie-downs.

A special thanks to Action Turbo (Santee, CA) for the turbo cut-away loaner, and to Butch Olhausen for loaning us his F-250 for filming!

As always, be sure to stick around to watch our out-takes at the very end during the credits!


This episode features an original Motorz theme song by Jeremy Pritchard.

  1. For the most part the Video talks about the simple stuff that I have known for over 30 years. I have however had the hardest time trying to find out what an acceptable exhaust gas temp is. He said 1200 F continuous and 1,400F for not over 1 minute. I have a 3208 Cat that really pushes this if I don’t drop down a gear.. I need a bigger radiator and I want to install water injection. Then I can run it harder in a 6 wheel drive truck that I spread lime with.

  2. yes 3 to 4 gallons is the same at 12 to 16 quarts. When you say stuff like this in a video I no longer trust everything you say

  3. “Longer strokes create more torque, due to a longer connecting rod.” False. Longer stroke creates more torque, due to a longer distance from center of the crankshaft to the center of the crank pin, which increases actual stroke length of the piston in the cylinder.
