Motor Oil & Fluids Deals

Cheap motor oil and engine fluids

Cheap motor oil in full synthetic, synthetic blend, high-mileage and conventional grades is grouped here in quarts and jugs. Coolant plus brake, transmission, power steering and washer fluids sit alongside, which helps hands-on drivers handle routine oil changes and fluid top-offs in their own driveway.

Cheap motor oil and fluids: which ones does your vehicle need?

• Find the viscosity, such as 5W-30, and the spec your engine requires in the owner's manual.
• Full synthetic oil resists breakdown at high heat, while conventional oil still fits engines whose manual calls for it.
• Coolant, transmission fluid, and brake fluid come in different types, so use the type named in the manual rather than mixing.
• On any bottle, look for the industry certification symbol, which shows the oil meets current engine standards.

Which suits you: Drivers whose manuals call for synthetic should stick with full synthetic, while owners of high-mileage cars may prefer high-mileage blends.
