Most "what oil?" questions are really grade questions. Here is what the common ones are built for.
Newer engines, cold climates. Thinnest flow for fast starts and fuel economy.
The all-rounder. The most common spec in North America.
Performance & diesel. Holds thicker when hot — turbos and towing.
Older or high-mileage. Extra hot-viscosity cushion for worn engines.
Our standard
Oil advice is worthless if it ignores your engine's spec. Everything here anchors to what the manufacturer actually calls for.
Grades and approvals trace to owner's-manual requirements and standards like API and ILSAC.
The 3,000-mile rule and "thicker is better" get called out where they show up, with the reasoning.
If a guide and your manual disagree, the manual wins — and we say so. Read the editorial policy.
Straight talk on engine oil — grades, brands, and what your car actually needs.
