Filters, oil, and fluids
6 part types · what each does and where to compare prices
- 01Oil filterTraps wear particles in the engine oil. Change it with every oil change.
- 02Engine air filterCleans the air going into the engine. A clogged one costs power and fuel economy.
- 03Cabin air filterCleans the air coming through the heater and A/C vents. Not every older vehicle has one.
- 04Fuel filterCatches debris before it reaches the injectors. Many newer vehicles put it inside the fuel tank with the pump.
- 05Motor oilLubricates and cools the engine. Use the grade and the approval standard your manual lists.
- 06Transmission fluidAutomatic transmissions are sensitive to fluid type. Use the exact specification named for your transmission.
Before you order
- Oil viscosity and specification are printed in the owner's manual and often on the oil filler cap.
- Filters that look alike can differ in bypass valve setting and thread size. Match the listing to your engine.
