Video transcript

SAE 30 is a single-grade oil with a higher viscosity, suitable for warmer temperatures and older engines. 5w-30 is a multi-grade oil, offering better performance across a wider temperature range; it remains fluid in cold conditions (5w) and maintains thickness at high temperatures (30). Use SAE 30 for consistent, warm climates, while 5w-30 is better for varying temperatures and newer engines.
