e best way to deal with fouling is to prevent it from happening.
- Regular Oil Changes: Use high-quality oil and change it at the manufacturer’s recommended intervals. This removes contaminants before they can settle in the cooler.
- Use Quality Filters: A full-flow oil filter is the first line of defence in capturing abrasive particles that contribute to fouling.
- Maintain the Cooling System:
- For air-cooled systems: Keep the exterior fins clean.
- For water-cooled systems: Use the correct coolant mixture and change it as scheduled to prevent scale and corrosion.
- Avoid Overheating: Address any underlying issues that cause the oil or engine to overheat, as heat is the primary driver of oil degradation and fouling.
- Monitor Performance: Keep an eye on oil temperature and pressure gauges. A gradual change in these readings is often the first sign of fouling.
