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.
