It focuses on the gasoline SkyActiv-G engine most common in that year and notes regional differences where applicable, plus practical tips to keep your engine running smoothly and within warranty.
Recommended oil specifications
Use the following specifications as your buying guide when selecting oil for the 2016 Mazda6.
- Viscosity: 0W-20
- Oil type: Full synthetic
- Specifications: Oil should meet ILSAC GF-5 or GF-6 and API SN (or newer) performance standards

Adhering to these specifications helps ensure optimal protection, fuel efficiency, and long-term reliability for the SkyActiv-G engine in the Mazda6.
Maintenance intervals
Oil change intervals vary by driving conditions, but Mazda’s guidance for the 2016 Mazda6 with synthetic oil typically aligns with these general timelines.
- Normal driving: about every 7,500 miles (12,000 km) or 12 months, whichever comes first
- Severe service (frequent short trips, towing, extreme heat or cold): more frequent changes, commonly around 5,000 miles (8,000 km) or 6 months, whichever comes first
Always refer to the owner’s manual for the exact interval for your trim and region, and adjust for local climate and usage. Using the recommended 0W-20 synthetic oil and sticking to the specified interval helps maintain fuel efficiency and engine cleanliness.
Regional and engine-variant notes
The 2016 Mazda6 existed in various markets with potential engine variants. While the gasoline SkyActiv-G 2.5L is the most common in many regions, diesel or turbo variants may have different oil requirements. Always verify the correct specification in your local owner's manual or consult a Mazda dealer if you’re in a market with alternative engines.
- Gasoline engines (most markets): follow the 0W-20, synthetic, GF-5/GF-6, API SN or newer guidance above
- Diesel or turbo variants: check the engine-specific manual for the exact viscosity and spec, as requirements can differ by market
In short, the safest approach is to rely on the official owner’s manual for your exact vehicle configuration and region, and choose a high-quality synthetic oil that meets the stated specifications.
