Engine oil and filter recommendations
SAE 5W-20 engine oil is recommended
Look for this certification
trademark.
Use SAE 5W-20 motor oil certified for gasoline engines by the American
Petroleum Institute (API).
Motor oil displaying the API certification trademark will meet all
requirements for your vehicle's engine.
Do not use supplemental engine oil additives, oil treatments or engine
treatments. They are unnecessary and could, under certain conditions,
lead to engine damage which is not covered by your warranty.
Change your engine oil and filter according to the appropriate schedule
listed in the service maintenance section.
Mazda production and replacement oil filters are designed for added
engine protection and long life. If a replacement oil filter is used that
does not meet Mazda material and design specifications, start-up engine
noises or knock may be experienced.
It is recommended you use the appropriate Genuine Mazda oil filter (or
another brand meeting Mazda specifications) for your engine application.
