Routine diesel maintenance can be equal parts satisfying and aggravating. An oil change may seem like a simple task, but the runaround—from miscommunicating with counter staff to paying dealer prices—can turn routine into a headache. And besides all that, it’s hard to know if the product you’re using is actually doing a good job protecting your engine. It doesn’t need to be that way, though, and AMSOIL is here to help. For decades, AMSOIL has led the synthetic-lube revolution. In 1972, it became the first company to earn an API certification for synthetic motor oil, solidifying its reputation as “The First in Synthetics.” Today, AMSOIL offers a comprehensive line of diesel-specific formulations engineered for heavy-duty use and long-drain intervals. Here are the key reasons diesel owners are reaching for AMSOIL…

When you think of endurance racing, images of high-revving gasoline screamers often flood the mind. Tons of machines built for power, speed, and aggression. But in 2006, Audi did something no one expected. They didn’t just challenge the gasoline establishment; they overthrew it—with a diesel. Enter the Audi R10 TDI, the first diesel-powered racecar to win the 24 Hours of Le Mans and arguably the most disruptive force to ever hit endurance racing. Audi’s decision to field a diesel prototype wasn’t a gimmick. It was a calculated risk, backed by engineering confidence and a deep understanding of both competition and innovation. The R10 TDI was built to replace the R8, which was an already legendary gas-powered car that won Le Mans five times, just with a radical twist: a 5.5-liter…

While the smoke has settled and the dust has cleared the air at the iconic Lucas Oil Raceway, it’s hard to believe that another incredible Ultimate Callout Challenge has come to pass. While we’re sad it’s over, we’re happy that it happened, and in case you missed it, we’ve got you covered. At the 2025 Ultimate Callout Challenge (UCC), attendees didn’t just witness the biggest event in its history—they became part of it. From the ultra-competitive ODSS/ODR drag classes and the invite-only Seventy2 Fast bracket to the countless booths in the alleys of DPI, UCC felt less like a show and more like a diesel-fueled family reunion. The team behind Ultimate Callout Challenge has been building this momentum for years. What started as a niche event for high-performance diesel fans…

 When I first started Big Time Kustomz, I instantly became obsessed with horsepower and the Power Stroke motors,” says Mark Vanadia. “We spent years trying to make my pride-and-joy red truck that was lifted 10 inches and on 24-inch wheels and 38-inch tires go fast with more power. I learned after capping 1,000 hp that the task takes a toll on a truck that big. I always spent more time fixing it than enjoying it. I found a rolling chassis that had a roll bar in it and instantly fell in love with the idea of building a dedicated, fast, power-driven truck. I believe the words from my wife were, ‘Buy the truck so you can stop complaining about breaking your red truck.’ So I did.” “Instantly, I reached out…
