Does the Tharu Burn Engine Oil?
2 Answers
The Tharu engine may experience some oil burning, but this is more common in older models. Newer Tharu models have relatively less oil burning unless there is a vehicle malfunction. Engine oil naturally has a certain level of consumption, but excessive consumption indicates an oil-burning issue. Many factors can influence oil burning, such as fuel quality, driving conditions, driving habits, and maintenance practices. These factors can exacerbate oil consumption in the Tharu, leading to oil burning. There are two types of "oil burning": The first is cold-start oil burning, where thick blue smoke is emitted from the exhaust pipe during the first start of the day, which disappears after a while. The second is acceleration oil burning, where a large amount of blue smoke is emitted from the exhaust pipe when the accelerator is pressed hard while driving or when the vehicle is idling. Methods to prevent oil burning in cars: Choosing the right engine oil: For older vehicles with increased gaps between pistons and cylinder walls, thicker oil can be chosen to enhance sealing. Additionally, oil quality is crucial. Owners with the means should opt for qualified semi-synthetic or full-synthetic oils. Although maintenance costs may increase slightly, these oils have a longer lifespan, slower degradation, and better thermal stability and resistance to viscosity changes. Avoid aggressive driving in new cars: Generally, new cars today do not require a break-in period, but for the first 2,000 kilometers, internal components like the engine and transmission need time to achieve optimal coordination. During this period, avoid behaviors like flooring the accelerator or high RPMs (over 4,000) to prevent oil burning caused by poor internal component coordination. Regular and timely maintenance: Engine oil operates in harsh conditions, and even full-synthetic oil cannot last indefinitely without replacement. Additionally, oil filters and air filters are crucial and should be replaced on schedule to prevent impurities from entering the cylinders and causing wear.
My Tharu has been running for almost three years now, and I occasionally pay attention to the oil consumption issue. From a professional perspective, oil burning did exist in some early models, mainly related to design flaws in Volkswagen's EA888 engine, such as poor piston ring sealing or wear on the valve guides. I recommend always checking the oil level during routine maintenance, inspecting the dipstick every 1,000 kilometers. If the oil level drops quickly or blue smoke comes out of the exhaust pipe, send it for repair immediately. Don’t skimp on cheap, low-quality oil—choosing a full synthetic 5W-40 grade is more suitable and can extend the engine's lifespan. If severe oil burning is detected, the dealership can fix it through software updates or part replacements, which aren’t costly, but don’t delay to avoid damaging the catalytic converter and incurring major repair expenses.
