What to Do if the Magotan Car Burns Engine Oil Severely?
3 Answers
The solutions for severe engine oil burning in Magotan cars are as follows: 1. Use engine oil that meets the vehicle's technical requirements. When selecting engine oil, pay attention to both the quality and viscosity specifications. The quality specification should preferably be SL or higher, and the viscosity must strictly adhere to the vehicle manual's requirements—neither too low nor too high. 2. Avoid frequent rapid acceleration and prolonged high-speed driving. When the engine runs at excessively high speeds, it can break the lubricating oil film, leading to poor lubrication and dry friction in moving parts. If this becomes a regular practice, it can cause abnormal engine wear and result in oil burning. 3. Ensure the engine oil is filled according to specifications. If the oil level exceeds the midpoint, ask the mechanic to drain the excess oil. 4. Visit a service station for inspection as soon as possible. If the issue is due to engine faults (such as poor piston ring sealing, leaking valve seals, or cylinder gasket leaks), have the vehicle repaired promptly at a service station.
Last year, I repaired over a dozen Volkswagen Magotans with oil burning issues, mostly caused by problems with the second-generation EA888 engine. The key is to diagnose step by step: first, measure the cylinder pressure to rule out cylinder scoring risks, then use a borescope to check for vertical scratches on the cylinder walls. About 80% of the cars suffered from carbon buildup causing piston ring sticking. After walnut blasting the intake ports and soaking the cylinders to remove carbon deposits, driving for 2,000 km often shows improvement in many cases. If the issue persists, focus on checking the oil separator—the OEM vacuum valve from Volkswagen is particularly prone to failure. Remember, don’t rush into an engine overhaul. One car spent 23,000 RMB on upgraded piston ring assemblies, only to later discover it was a faulty PCV valve, making the effort pointless. Regular use of fuel additives for cleaning can significantly delay these problems.
My Magotan B7L suddenly started burning oil after driving 80,000 kilometers, which was terrifying! During maintenance, 4 liters of oil were added, but after 3,000 kilometers, the dipstick couldn't detect any oil. The 4S shop said the engine needed to be disassembled and quoted 28,000 yuan. Later, I took it to a specialized repair shop where the technician used equipment to diagnose the issue and found that the valve stem seals had aged. Replacing the seals only cost 4,200 yuan, and I also had the turbocharger's sealing rings replaced while at it. Now, it consumes half a liter every 5,000 kilometers, which is completely within the normal range. I recommend using 0W-40 full synthetic oil with 502 certification during maintenance—higher viscosity actually reduces consumption. Keeping 1 liter of oil in the trunk is really necessary!
