Maintenance and Specifications
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). An oil with this trademark symbol conforms
to the current engine and emission system protection standards and fuel
economy requirements of the International Lubricant Standardization and
Approval Committee (ILSAC), comprised of U.S. and Japanese
automobile manufacturers.
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 scheduled maintenance.
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 Mazda oil filter or another
with equivalent performance for your engine application.
