Choosing between a prime-rated and a standby-rated generator set comes down to one question: how often will the engine actually be running under load? Get that answer wrong, and you either pay for capacity you don’t need or end up with a unit that wears out years ahead of schedule. This guide breaks down what…

In the construction and heavy equipment industries, every single hour of unplanned downtime translates directly into thousands of dollars in financial losses. Whether it is an excavator, bulldozer, crane, or wheel loader, on-time project delivery hinges entirely on a highly reliable “heart” within the machinery. Among the myriad of powertrain brands available, Cummins construction engines have…

In modern open-pit and underground mining operations, time is money. Once a 300-ton mining haul truck or a massive excavator shuts down due to a powertrain failure, the resulting chain reaction can cost a mine tens of thousands of dollars per hour. In such high-pressure, extreme operating environments, the reliability of the powertrain dictates the…

The Cummins X15 has earned a strong reputation in the heavy-duty trucking world and for good reason. It powers everything from long-haul semi trucks and Class 8 freight haulers to motorhomes and fire apparatus, delivering between 400 and 600 horsepower depending on configuration. For a diesel engine expected to run a million miles, it mostly…

Cummins ISX fuel system problems are one of those things that a lot of heavy duty truck owners don’t really think about. Not until the truck starts acting weird, anyway. And honestly, it’s super common on high mileage rigs. You might just feel like the truck is “getting tired.” It takes longer to start. Or when…

If you own a truck with a 6.7 Cummins, chances are you have looked at the oil pressure gauge at some point and wondered whether the reading was normal. This usually happens after the engine warms up and the pressure suddenly looks lower than expected at idle. One owner sees 15 PSI at a stoplight…

When most people shop for a diesel engine, they look at the sticker price and stop there. That’s understandable — it’s the number right in front of you. But here’s what experience in the field keeps proving: the purchase price is just the beginning. The real difference between Cummins and Perkins shows up months or…

Considering the effect of fuel injectors on combustion efficiency, power, and engine lifespan, we present a question that many users or prospective buyers would have in mind: What are the differences between 5.9 vs 6.7 Cummins injectors? Are they interchangeable? The short answer? No. But the why matters more than the answer itself. Pick the wrong…

If you are servicing a Cummins X15, one of the first questions that comes up is simple: how much oil does it actually need? The short answer is that most Cummins X15 engines take around 10–11 gallons of oil, or 40–44 quarts, including the filter. However, that number is not always identical across every truck. Oil…

The 5.9L Cummins engine and the 6.7L Cummins engine exist as two distinct engine options which drivers will decide between after they determine which engine performs better. The 6.7L Cummins engine offers advanced capabilities through its greater power output yet the implementation of contemporary emissions control systems makes the engine more difficult to operate. The…
