Hidden Diesel Problems Hurting Trucks, Tractors, and other Motors

Diesel technology has come a long way — but with tighter emissions systems, DPFs, EGRs, and high-pressure injectors, today’s engines are also more vulnerable than most operators realize.

In this episode of the Farm4Profit Podcast, we’re joined by Garth Redifer, Vice President of Sales at Power Service, a third-generation, veteran-owned diesel additive manufacturer based in Weatherford, Texas. With 17 years of hands-on diesel technology experience, Garth has worked directly on innovations like diesel injector cleaning and DPF flush solutions — and has seen firsthand where engines fail and why.

We dig into:

Why modern diesel engines are more prone to injector deposits, regen issues, and power loss

What’s really happening inside your fuel system, turbo, EGR, and DPF

Why excessive DPF regens cost you fuel, time, and engine life

How a one-tank diesel treatment can clean the entire fuel system — not just injectors

What REGENEXTEND™ technology does and how it can cut regen frequency by up to 50%

The difference between “band-aid” fuel additives and science-backed solutions

Why preventive maintenance is cheaper than waiting for warning lights and downtime

Garth also shares insights from working with truckers, farmers, logging crews, and fleets across North America — and explains why diesel fuel quality and maintenance matter more now than ever.

Whether you’re running a pickup, tractor, combine, semi, or full fleet, this episode will help you understand how to protect performance, extend engine life, and keep more money in your pocket.
