What’s a good price for motor oil?

How to land in the good-price band

Motor oil is priced almost identically across viscosities — the choice is your engine’s spec, and the savings are all in pack size and brand.

• •Buy the 5-quart (or larger) jug, never single quarts. Single quarts can cost 2× the per-quart price of a jug — the biggest lever in the category.
• •Match the exact grade your owner’s manual lists (e.g. 5W-20 vs 5W-30). They cost the same, so there’s no money reason to deviate — only a protection reason to follow the spec.
• •Buy the cheapest brand that carries the right API/ILSAC certification for your engine. The certification donut on the bottle matters far more than the brand name.
• •Full synthetic lasts longer between changes than conventional, which lowers your real cost per year even at a higher per-quart price.
