How to Solve the Oil Burning Issue in DS5?
4 Answers
For older vehicles, using engine oil with higher viscosity is also an option. Oil burning refers to the situation where engine oil enters the combustion chamber of the engine. The maintenance cycle of a car is determined based on its normal usage conditions. It is advisable to shorten the maintenance cycle and the prescribed mileage according to the actual situation, and also try to avoid prolonged high-speed driving.
Having driven for decades, the DS5's oil burning issue is quite common, mainly caused by internal engine wear such as aging piston rings or failed valve seals allowing oil to enter the combustion chamber and burn. If you notice rapid oil consumption, check the dipstick immediately – exceeding 500ml per 1,000km is critical. Try switching to high-viscosity full synthetic oil to slow consumption; severe cases require an engine overhaul to replace seals, costing at least several thousand yuan. Regular oil and filter changes can prevent this. Don't wait for the warning light – blue exhaust smoke signals oil burning. This repair is expensive but early action saves major costs. Don't risk engine failure plus tow fees.
Oil burning in DS5 is mostly caused by piston ring wear or turbocharger oil leakage. I recommend self-checking first: monitor the oil consumption rate every two refuels. If it decreases rapidly, try replacing the PCV valve as it's a low-cost solution. Secondly, check for blue smoke from the exhaust. If obvious, seek professional diagnosis for a compression test or leak test. Use the manufacturer-recommended oil grade, such as 5W-30 full synthetic oil, to reduce consumption. Regular maintenance is crucial; clean carbon deposits if excessive. In case of a major overhaul, costs can range from a few thousand to tens of thousands. Prioritize safety over saving money.
Group members often discuss the common issue of DS5 burning oil. The solutions usually involve checking the oil consumption rate and changing the oil regularly. Using additives to clean carbon deposits might help sometimes but isn't reliable. If anything seems off, immediately go to a specialized repair shop to scan for fault codes. After they repaired the piston rings, the problem disappeared. Pay attention to engine health—prolonged oil burning can lead to cylinder scoring, which is serious, so address it promptly without delay. Maintain it well by checking the oil level monthly to save money and stay worry-free.
