What is the solution for excessive oil consumption in the 2014 Peugeot 408?

[AlexanderLynn]

The solutions for excessive oil consumption in the 2014 Peugeot 408 are: 1. Use higher viscosity engine oil to improve the sealing between engine pistons and cylinder walls; 2. Regularly check the oil dipstick and change the engine oil and oil filter periodically, using genuine oil filter components; 3. If the engine oil consumption problem is severe, it is recommended that the owner visit a 4S store for inspection and repair, or consult the manufacturer for maintenance. Taking the 2020 Peugeot 408 230THP 10th Anniversary Edition as an example, this car is a compact model with a length, width, and height of 4750mm, 1820mm, and 1488mm respectively, and a wheelbase of 2730mm. The front suspension is a MacPherson independent suspension, and the rear suspension is a torsion beam non-independent suspension. It is equipped with a 1.2L turbocharged engine with a maximum horsepower of 136ps, a maximum power of 100kw, a maximum torque of 230nm, and is paired with a 6-speed dual-clutch transmission.

As a long-time enthusiast of Peugeot vehicles, I've noticed that the oil burning issue in the 2014 408 model is quite common, primarily caused by piston ring wear or aging valve stem seals allowing oil to seep into the combustion chamber. The solution is straightforward: First, take it to a professional repair shop for a comprehensive diagnosis, including engine compression tests and smoke tests to pinpoint the leak. If it's confirmed to be a piston ring issue, simply replacing them usually costs between 2,000-3,000 RMB. For aging valve stem seals, the solution is also replacement, supplemented with sealant. For daily prevention, it's recommended to use high-viscosity fully synthetic oil like 5W-40, which maintains better sealing at high temperatures. Check the oil dipstick every 5,000 kilometers and top up promptly, and avoid aggressive long-distance high-speed driving to reduce wear. Why is the older 408 model prone to oil burning? Because its 1.6T engine has minor sealing design flaws under certain conditions, though it doesn't affect overall safety. Timely repairs can prevent carbon buildup from damaging the catalytic converter, saving you from bigger expenses.

My 2014 Peugeot 408 started burning oil last year after several years of use. The oil warning light would come on before reaching 3,000 km after each refill. The solution was to take it directly to the 4S shop for inspection by technicians. The mechanic diagnosed it as worn piston rings and replacing them fixed the issue; oil seal problems would require similar treatment. I always use the manufacturer-recommended full synthetic oil, changing it every 5,000 km without altering the viscosity grade, as wrong grades reduce effectiveness. I also use engine cleaner regularly to remove carbon deposits. Oil burning wastes money and pollutes the environment, with excessive emissions causing bigger issues. Early repairs saved me money—the total cost was around ¥2,500, far cheaper than engine replacement. For prevention, I check the oil level every two weeks, keeping it at the proper level, neither too high nor too low.

I find it quite annoying that this car burns oil, which is often caused by engine wear such as broken piston rings. The solution is to find a reliable repair shop for inspection and replace the faulty parts once diagnosed. Don't try to save money by using fake engine oil; it's recommended to use high-temperature-resistant full synthetic oil. Regular maintenance is key—avoid prolonged idling or sudden acceleration. Prolonged oil burning can damage the engine and reduce fuel efficiency, so addressing it early helps maintain performance and emissions.
