If you’re not sure about your Mazda6 2015 oil type, or the oil type for any other Mazda model, this quick guide will help you find the right blend for you. Most Mazda models use one of two oil types, depending on whether or not you have a turbocharged powertrain. If you’re still not sure, visit Hiley Mazda of Arlington — our technicians will find the type for you in no time.

Standard MAZDA Engines

Like most modern Mazda models, the 2015 Mazda6 runs best with SAE 0W-20 full synthetic engine oil. This is a low-viscosity oil that is perfect for most engines produced after SKYACTIV®-G engines were introduced, offering improved fuel efficiency and fewer cold-starting issues. Whether you’re driving a 2015 Mazda6 or a contemporary 2026 Mazda3, as long as your engine isn’t turbocharged, this is the best option.

Turbocharged MAZDA Engines

If you have a turbocharged engine under the hood, the oil type you'll need depends on which engine you have. Most turbocharged Mazda vehicles with the 2.5-liter engine, such as the Mazda CX-5 Turbo, Mazda CX-9, and Mazda6 Turbo, require SAE 5W-30 oil to handle the higher heat and stress of turbocharging. However, models with the newer 3.3-liter inline-six turbocharged engine, like the 2026 Mazda CX-90 and Mazda CX-90 Turbo S, use SAE 0W-20 oil.

Always check your owner's manual to confirm the correct oil specification for your specific Mazda vehicle and engine.

Should I Use Full Synthetic Oil?

You should always use full synthetic oil, whether you’re driving the 2015 Mazda6 or a contemporary model. Full synthetic oil responds better to extreme changes in heat, keeps the engine cleaner, and lets you drive for longer between oil changes.
