Engine Oil for Peugeot 308: Best Oil Types, Grades, Capacity & Change Guide

Choosing the right engine oil for Peugeot 308 is not just a routine task. It plays a direct role in how smooth your drive feels, how long the engine lasts, and how much fuel you save over time. Many owners feel unsure because Peugeot 308 comes with different petrol and diesel engines, each with its own oil needs. If you have ever stood in an auto store wondering which oil really fits your car, you are not alone. This guide clears the confusion in simple words, so you can choose the right oil with confidence and protect your engine every day.

Understanding Peugeot 308 Engines

Petrol Engine Variants

Peugeot 308 petrol models include small turbo engines and larger naturally aspirated options. These engines run at higher temperatures and need oil that stays stable under heat. Using the wrong oil can lead to rough idling, higher fuel use, and faster wear. The right oil keeps moving parts smooth and reduces stress during short city drives.

Diesel Engine Variants

Diesel versions are popular for their torque and fuel economy. They usually come with a diesel particulate filter that traps soot. This makes oil choice even more important. Using the correct low ash oil helps protect the filter and prevents warning lights. Diesel engines also need oil that handles higher pressure.

Turbocharged Engine Needs

Turbocharged engines spin very fast and generate extra heat. Oil must cool and lubricate the turbo properly. Poor oil choice can damage the turbo bearings. This is why Peugeot recommends specific oil grades for turbo petrol and diesel engines.

Why Oil Specs Matter?

Engine oil is more than just thickness. It has additives that clean, protect, and reduce friction. Peugeot engines are designed to work with specific oil standards. Matching these standards helps avoid long term engine issues and keeps warranty safe.

Recommended Oil Grades Explained

5W30 Engine Oil Use

5W30 engine oil for Peugeot 308 is the most common choice. It flows well during cold starts and stays stable at high temperatures. This makes it ideal for daily driving and modern engines. It also supports fuel efficiency and cleaner emissions.

5W40 Engine Oil Option

Some older petrol and diesel engines may allow 5W40 oil. This oil is slightly thicker at high temperatures. It can be helpful for engines with higher mileage. Always check engine type before switching grades.

Low SAPS Oil Importance

Diesel engines with particulate filters need low SAPS oil. This type reduces ash buildup inside the filter. Using the wrong oil may block the filter and trigger dashboard warnings.

Fully Synthetic Oils

Most Peugeot 308 engines perform best with fully synthetic oil. It resists breakdown, keeps the engine clean, and lasts longer between changes. This is especially useful if you drive in traffic or hot conditions.

Best Engine Oil for Peugeot 308 Diesel
