In this video I share the 5 diesel oil change tricks that are used by mechanics to ensure reliability and less diesel engine problems. The difference between a diesel engine that dies at 100,000 miles and one that runs strong at 350,000 miles isn't luck or build quality. It's how you handle one critical maintenance task that most diesel owners get completely wrong.

Number one: Change engine oil every 5,000 to 6,500 miles, regardless of what the manual says.

Your owner's manual might recommend 10,000 or even 15,000-mile oil change intervals, but here's what the manual doesn't tell you. Those extended intervals are designed around optimal conditions that rarely exist in the real world.

Diesel engines are fundamentally different from gasoline engines. They run higher compression ratios, operate under greater loads, and produce more combustion byproducts that contaminate the oil. Modern emissions systems make this worse by recirculating exhaust gases that introduce soot and acids directly into your crankcase.

The oil companies and manufacturers want you to believe modern synthetic oils can handle these extended intervals, and technically, they can. But there's a difference between oil that won't cause catastrophic failure and oil that provides optimal protection.

Here's what happens during those extra 5,000 miles between changes. Your oil accumulates soot particles that act like liquid sandpaper on internal components. Acids from combustion byproducts start corroding metal surfaces. The oil's additive package becomes depleted, reducing its ability to neutralize contaminants and maintain proper viscosity.

Trick number two: Change the oil filter every single oil change.

This might sound obvious, but you'd be surprised how many diesel owners try to save money by reusing oil filters for two oil changes. This is one of the most expensive false economies in diesel maintenance.

Your oil filter doesn't just remove particles. It's designed to maintain proper oil pressure and flow throughout your engine. A used filter has already trapped contaminants and begun to restrict flow, even if it looks clean on the outside.

Here's what most people don't understand about diesel engine filtration. Diesel engines produce significantly more soot than gasoline engines. This soot consists of carbon particles smaller than human hair that can only be removed by high-quality filtration.

When you reuse a filter, you're starting your fresh oil change with a filter that's already partially clogged and has contaminants embedded in the filter media. Within a few hundred miles, that reused filter begins bypassing unfiltered oil directly back to your engine.

Modern diesel engines with tight tolerances and turbochargers are especially vulnerable to contamination. The high-pressure oil pumps that feed your turbocharger bearings require absolutely clean oil to prevent damage. A marginal filter can cause turbo failure that costs thousands to repair.

Always use a high-quality filter specifically designed for your diesel engine. Cheap filters may fit, but they often have inadequate filtration media or bypass valves that open too early under pressure.

Trick number three: Avoid short trips and heavy traffic conditions whenever possible.

Short trips are diesel engine killers, and most owners don't realize how much damage they're causing with seemingly innocent driving patterns.
Diesel engines need to reach full operating temperature to function properly. This isn't just about the coolant temperature gauge reaching normal range. The engine oil needs to reach 180 to 200 degrees Fahrenheit to evaporate moisture and fuel contamination that accumulates during combustion.

Short trips prevent this critical heating cycle from completing. Water vapor from combustion condenses in your crankcase, mixing with oil to form acids and sludge. Unburned fuel dilutes the oil, reducing its protective properties and promoting carbon formation.

Heavy traffic creates similar problems. Constant idling and low-speed operation prevents your engine from reaching the temperatures needed for proper oil conditioning. Your diesel runs rich during these conditions, sending more fuel vapors into the crankcase through blow-by.

The solution isn't complicated. Once a week, take your diesel on a 20 to 30-minute highway drive at steady speeds above 55 mph. This allows the engine and oil to reach proper operating temperatures, burning off contaminants and maintaining oil quality between changes.
If your daily driving consists mainly of short trips, consider changing your oil more frequently, perhaps every 4,000 to 5,000 miles instead of 6,000.
