In diesel engines, small diesel engine problems don’t stay small.
A slight drop in oil pressure. A little smoke at startup. A minor coolant leak. An injector that’s “just a little off.”
These are easy to ignore, especially when the truck is still running.
But in heavy-duty diesel engines, those early warning signs are not minor inconveniences.
They are the beginning of a much bigger failure.
Continue reading The Real Cost of Waiting Too Long to Fix a Small Diesel Engine IssueIf you want to prepare your diesel truck for winter, it starts with understanding how cold temperatures affect your engine, fuel system, and overall performance.
Cold weather introduces challenges that diesel engines are particularly sensitive to, including fuel gelling, reduced battery performance, and increased wear during startup.
Preparing ahead of time helps prevent breakdowns, hard starts, and costly repairs.
Continue reading How to Prepare Your Diesel Truck for Winter (Cold Weather Guide)You may not realize it, but there are a lot of components that make up the cylinder head of your C15 ACERT. If you have a failure in that part of your engine, you might be inclined to blame it on your cylinder head, but it’s possible that one of these other components could break. This would lead to problems with similar symptoms to that of a failing cylinder head.

A turbocharger failure can look like a bad part.
Loss of power. Smoke. Noise. Oil leaking. Shaft play.
But in many heavy-duty diesel engines, the turbocharger is not the real starting point of the failure. The damage often begins somewhere else in the lubrication system.
The number one issue that destroys turbochargers is oil starvation. When a turbo does not receive a steady supply of clean, pressurized oil, internal damage can happen fast: sometimes within seconds under load.
Continue reading Why Oil Starvation Destroys Diesel TurbochargersIf you run trucks, manage repairs, or budget for diesel work, fuel price changes matter fast.
As of April 13, 2026, the global average retail diesel price was $1.60 per liter, according to GlobalPetrolPrices. Their dataset notes that some countries are updated weekly and others monthly, depending on how their fuel markets are regulated.
What stands out most is not just the average. It’s the spread.
On the low end, a few heavily subsidized or regulated markets were still posting diesel prices near zero in U.S. dollar terms. On the high end, some developed markets were above $2.50 per liter, with Hong Kong above $4.50 per liter.

Even when it meets specification at delivery, contamination can develop during storage, transport, or in your own fuel system. Over time, these contaminants affect fuel lubricity, combustion quality, and component life.
The most damaging contaminants are not always visible, but they leave very real mechanical consequences.

An inframe rebuild on a Cummins ISX 870 or ISX 871 is supposed to bring your engine back to life.
But for a lot of operators, that’s not what happens.
Instead, they run into problems almost immediately:
The issue usually isn’t the rebuild itself.
It’s what happens during – and right after – the rebuild.

Caterpillar C15 ACERT engines don’t fail the same way older single-turbo engines do.
They operate under higher cylinder pressures, increased exhaust temperatures, and more complex airflow management due to the ACERT twin turbo system.
When these engines reach rebuild time, the failure is usually tied to one thing:
Heat and pressure overwhelming the cylinder assembly.
This is what drives liner wear, ring failure, and ultimately the need for an inframe rebuild.
