How to Solve the Problem of Peugeot 408 Burning Engine Oil?

Peugeot 408 burning engine oil can be solved as follows: 1. For vehicles that have been used for a long time, you can choose to use engine oil with higher viscosity to increase the sealing between the engine piston and cylinder wall. 2. Frequently check the oil dipstick, regularly change the engine oil and oil filter as required by the product manual, and replace with genuine oil filter parts. 3. If the problem of engine oil burning is serious, it is best to go to a 4S store for inspection and repair, or consult the manufacturer for maintenance. The causes of engine oil burning in vehicles include: 1. Damage to the exhaust valve causing abnormal oil consumption. 2. Aging of engine valve oil seals and stuck piston rings leading to oil consumption.

I've driven a Peugeot 408 for many years, and the oil burning issue is quite annoying, mainly caused by worn piston rings or aging valve stem seals in the engine. You should first check the oil consumption yourself, like inspecting the dipstick after driving 1,000 kilometers. If the oil level drops quickly, also pay attention to whether the exhaust pipe emits blue smoke. Don't delay, as running out of oil will destroy the engine. I recommend going to a 4S shop or a reliable repair shop for a compression test to diagnose the specific cause. The repair might involve replacing piston rings or seals, which isn't too expensive—just a few hundred to a little over a thousand yuan. For regular maintenance, using full synthetic oil and sticking to the oil change intervals can help slow down the problem. Oil burning is a common issue, so addressing it early can save you from costly major repairs later.

Speaking of the Peugeot 408 burning oil, I've encountered it. At first, the oil gauge dropped very quickly, and I thought it was a minor issue, but it turned out to be a leaking valve stem seal causing the trouble. The solution is simple—don't listen to online hype about additives; just have a mechanic inspect it directly. During the repair, they will disassemble the engine and replace the aging parts, which takes a few days, but once fixed, the oil consumption returns to normal. A reminder: regular checks are crucial—glance at the oil level every two to three thousand kilometers to prevent small issues from becoming big ones. Also, when burning oil, the engine sound becomes rougher, which is a signal. After one repair, I stuck with high-quality oil and regular changes, and the problem hasn’t recurred—saving both hassle and money.

Oil burning is common in the Peugeot 408, and the solution is to fix the root cause. Don't mess with additives yourself—they're ineffective and a waste of money. First, have the repair shop diagnose the issue. If it's a piston ring problem, replacing the set will suffice, and the cost is manageable. Ignoring oil burning will accelerate engine wear, doubling repair costs later. Regular oil changes can prevent premature wear.
