What type of engine oil is used for the Peugeot 308?
4 Answers
The Peugeot 308 uses engine oil of the specification 5W30, with the recommended maintenance oil being Total SL-5W-30. Here are the reasons: 1. Compared to 5W40, 5W30 has the same low-temperature fluidity but differs in high-temperature performance, where 5W40 offers better high-temperature protection and sealing. 2. Due to increased viscosity leading to higher engine running resistance and increased fuel consumption, 5W30 is relatively more suitable for the Peugeot 308's engine. Approximately 4L of oil is required when changing the oil for the Peugeot 308. Additional information: Naturally aspirated engines have relatively modest requirements for oil quality and can use mineral oil, semi-synthetic oil, or fully synthetic oil.
When driving my Peugeot 308, I checked the manual. My car is the 2018 petrol version, and it recommends using 0W-30 fully synthetic oil that meets the ACEA C2 standard. This oil has good fluidity, provides strong engine protection during cold starts, and minimizes part wear. I usually change the oil every 10,000 kilometers—any longer might lead to carbon buildup. Peugeot officially recommends brands like Total or Castrol. I tried changing it myself during a home maintenance session, and it resulted in lower fuel consumption and fewer headaches. If the engine is an older diesel version, you might need 5W-40 instead. That’s why I always say don’t just listen to others—checking your manual is the most reliable approach. Pay attention to certification marks when choosing oil, avoid cheap counterfeit products, as they can shorten your car’s lifespan. Regular maintenance is key.
As a DIY-loving car owner, I always change the oil for my 308 myself. Choosing 5W-30 full synthetic is the safest bet, with ACEA C2 certification as the baseline—the viscosity is just right for this car's turbocharged engine. Before getting started, gather all the necessary items: a new oil filter, a funnel, and safety gloves. Operate when the oil temperature is low, and dispose of the old oil responsibly. Don’t cheap out and use something like 10W-40, which is too thick—cold starts will be harder, and it can lead to oil burning. I change it every 8,000 kilometers, and mainstream brands like Mobil are fine. Remember, using the wrong oil grade will cause engine noise—check the manual to confirm the correct version, and address issues promptly to avoid costly repairs.
From an environmental perspective, using low-viscosity 0W-30 oil in the 308 can improve efficiency, reduce friction to lower fuel consumption, and decrease emissions for a greener planet. Full synthetic oil degrades faster, with oil change intervals within 15,000 km, keeping the engine clean. Choose certified oils like ACEA C2, a common standard for Peugeot. Avoid low-quality products that generate more waste, and maintain regularly to extend the vehicle's lifespan.
