Every truck operator knows, small parts can make a big difference. Your air filter and oil separator might not look like much, but they play a major role in keeping your engine healthy, efficient, and running smoothly.
At CLA Truck Parts we supply genuine European truck parts, including air filters and oil separators for Iveco Stralis and Eurocargo models, right here from Forrestfield, Perth. Let’s look at five key signs that it’s time to replace these two critical components before they cost you time and money on repairs.
1. Loss of power or poor engine performance
If your truck feels sluggish, struggles up hills, or just doesn’t respond the way it used to, your air filter might be the culprit. When the air filter gets clogged with dust and debris, your engine can’t “breathe” properly which leads to reduced combustion efficiency and lower power output.
An oil separator that’s past its best can also impact performance by allowing oil vapour to enter the intake system, leading to build-up and sensor contamination.
2. Excessive smoke or oil residue
Notice black smoke, increased exhaust haze, or oily residue around your intake system. That’s a clear sign your oil separator isn’t doing its job. Over time, separators become saturated and stop filtering oil mist effectively. The result:
- Oil gets pulled into the intake
- Contamination builds on turbochargers and intercoolers
- Emissions rise and efficiency drops
- Replacing the separator early prevents expensive downstream damage.
3. Higher fuel consumption
A clogged air filter makes your engine work harder, using more fuel to pull in the air it needs. If you’re noticing a sudden dip in your fuel economy, check your filters first before assuming a bigger issue. Regular filter changes are one of the simplest (and cheapest) ways to keep your running costs down, especially if you operate in dusty WA conditions.
4. Warning lights or engine fault codes
Modern trucks are packed with sensors that constantly monitor performance. A dirty air filter or blocked oil separator can trigger:
- Engine warning lights
- DPF or EGR fault codes
- Reduced power or “limp mode”
Check your filters. You’d be surprised how often a quick replacement clears the issue.
5. Scheduled service or preventive maintenance
Even if everything seems fine, filters and separators have service intervals for a reason. Changing them on schedule ensures consistent airflow, cleaner emissions, and longer engine life.
Our recommendation for most European trucks in WA conditions:
- Air Filter: Replace every 20,000–30,000 km or sooner if working in dusty areas
- Oil Separator: Replace every 80,000–100,000 km (or as advised by manufacturer)
