To reduce engine oil sludge build-up start by adhering strictly to the service schedule in your owner’s manual. Sludge forms when oil breaks down over time due to heat and contamination, so routine oil changes stop sludge from building up. Choose advanced full-synthetic engine oil, as it is far less prone to heat-induced degradation and اتوسرویس داوود provides superior defense against sludge than mineral-based oils.
Avoid short trips whenever possible, especially in cold weather, because the engine fails to warm up fully, which allows condensation and dirt to remain trapped. If your daily trips are consistently under 10 miles, consider reducing the mileage between changes.
Ensure the PCV system functions correctly by checking its operation regularly and swapping it when clogged. A clogged PCV valve can cause pressure buildup and oil leaks, which contribute to sludge. Ensure your radiator and coolant circulation are functioning optimally, since high temperatures cause rapid oil oxidation. Check for coolant leaks into the oil, which can create a thick, milky sludge.
Never add more oil than the dipstick indicates, as overfilling causes churning that weakens lubricant integrity. Finally, if your vehicle is older or has high mileage, consider incorporating a premium detergent-based oil cleaner, but only after consulting your mechanic or owner’s manual.
Proper care combined with appropriate lubricants are the most effective strategy for a healthy engine.
