@63nonnymarcel: Here's how to prevent it: ✅ Change your engine oil at the recommended service interval. Don't wait until the oil is completely worn out. ✅ Always use the oil grade and specification recommended by the vehicle manufacturer. ✅ Replace the oil filter every time you change the engine oil. ✅ Check your engine oil level regularly and top it up when necessary. ✅ Repair oil or coolant leaks immediately. Contamination speeds up sludge formation. ✅ Make sure the PCV (Positive Crankcase Ventilation) system is functioning properly to remove moisture from the engine. ✅ Avoid using low-quality engine oil and filters. Quality lubricants provide better protection and keep the engine cleaner. ✅ If you mostly drive short distances, take the vehicle on a longer drive occasionally so the engine reaches full operating temperature and burns off moisture. Remember: Routine maintenance costs far less than rebuilding or replacing an engine damaged by sludge. Take care of your engine today, and it will take care of you for years to come. #MechanicTips #EngineCare #CarMaintenance #lagosnigeria #xyzbca
