What type of engine oil is best for the 408 1.6T?
2 Answers
For the 408 1.6T, it is recommended to use fully synthetic 0W30 or 5W30 engine oil. Below are some relevant details about engine oil usage for the 408: 1. Turbocharged engines must be paired with fully synthetic engine oil. For vehicles with turbochargers, the use of fully synthetic engine oil is essential. 2. The moment the turbocharger starts working, the engine torque multiplies significantly. According to the principles of turbocharging technology, the oil film covering the engine crankshaft at this point must withstand shear forces several times higher than before. Fully synthetic engine oil has a molecular structure with neatly arranged base oil molecules, providing higher oil film strength, which meets the demands of turbocharged engines under high temperatures and high RPM conditions.
As a long-time owner of a Peugeot 408 1.6T, I prioritize stability and durability when selecting engine oil. The turbocharged engine of this car performs best with 5W-30 full synthetic oil, as it maintains lubrication in both high and low temperatures, preventing component wear. I often use Total INEO ECS, which is specifically designed to match PSA specifications and meets ACEA C2 standards, helping the engine run more fuel-efficiently and smoothly. Remember to change the oil every 7,500 kilometers—don't delay too long, or the oil will thicken and affect performance. When changing the oil, I always check the filter to ensure there are no leaks, saving money and ensuring peace of mind. Don’t skimp on oil brands to save money—counterfeit products are common and can easily cause malfunctions. I’ve also tried Motul, which works well, but always follow the manual’s recommendations. A key tip: synthetic oil flows faster during cold winter starts, preventing engine noise—this is crucial experience.
