How to Stop Oil Sludge Buildup in Your Volkswagen
Volkswagen cars are celebrated for their exceptional performance and reliability. Still, even these meticulously engineered cars can be plagued by common and persistent issues, one of which is oil sludge buildup. Your Volkswagen requires clean oil to function optimally, ensuring you have the best driving experience. However, oil degrades and becomes thick sludge over time. If you have ever observed that the oil you pulled out from your engine compartment is dark, dense, or has a pasty consistency, then there is a high chance that you are dealing with oil sludge.
Oil sludge within a Volkswagen engine can ruin your engine and cost you much more to fix than a routine oil change. The good news is that the formation of oil sludge is avoidable. To keep your Volkswagen’s engine clean and efficient, follow the maintenance tips provided by Oldwick Village Garage, located near you in Oldwick, New Jersey (NJ). However, before that, let’s delve into what oil sludge is exactly and the causes of its buildup.
What is an Oil Sludge? How does it happen?
Engine oil sludge is a thick, sticky substance that forms when oil loses its lubricating ability due to high temperatures, contaminants, and oxidation. In the long run, this gunky material builds up in the engine, blocks oil passages, and puts essential engine parts under great stress. This problem is more common in Volkswagen models with turbocharged engines or those cars that have been used beyond the recommended interval for oil change. The heat, as well as the stress put on the engine, makes Volkswagens more prone to sludge.
What Causes Oil Sludge Buildup in Volkswagen Engines?
Lack of Regular Oil Changes
One of the primary reasons for the formation of oil sludge is the infrequent changing of the oil. Over time, oil becomes denser as it absorbs any dirt, carbon, or moisture within the engine’s compartment. If left as is, it thickens into sludge, which clogs the oil ways and deprives your engine of the lubrication it needs.
Short Trips and Stop-and-Go Traffic
Short trips and stop-and-go traffic prevent the engine from reaching a high enough temperature to expel moisture and contaminants from the oil. This leads to the accumulation of sludge over time. If your Volkswagen is used only for city driving, you are more likely to experience this problem.
Defective PCV System
The positive crankcase ventilation (PCV) system of your Volkswagen helps expel undesirable gases and moisture from the car’s engine. If it fails, the excess moisture and combustion byproducts are collected in the oil and will form sludge much quickly.
3 Ways to Prevent Oil Sludge Buildup in Your Volkswagen:
1. Maintain Routine Oil Change
The best way to avoid oil sludge buildup is to change your oil regularly. Volkswagen recommends that its cars be oiled every 5,000 to 10,000 miles, depending on the particular model and usage conditions. However, if you drive in heavy traffic or extremely hot conditions, you may need to change the oil more frequently. Periodic oil changes help remove dirty oil from the car and replace it with fresh oil, effectively maintaining the engine’s lubrication and preventing the build-up of sludge. To get your Volkswagen’s engine checked, drive into any of our garages located near you in Oldwick, NJ.
2. Avoid Excessive Idling and Short Trips
If possible, avoid idling and make several short trips that will not allow the engine to warm up to the proper temperature. When you drive for long distances at a constant speed, the engine has an opportunity to expel moisture and contaminants from the oil, thereby minimizing the chances of sludge formation. If you find oil puddles under your car, visit any of our garages located near you in Oldwick, NJ.
3. Maintain Your Cooling System
A sound cooling system is essential in maintaining the engine’s temperature and preventing heat from degrading the oil. Ensure that you frequently check the coolant levels and clean the radiator to avoid blocking the cooling system’s airflow. The hoses should also be replaced if they are worn out, and the thermostat is also an essential part that should be checked for proper functionality.
