What does oil viscosity like 5W-30 mean?

Oil viscosity ratings like 5W-30 describe how the oil flows at different temperatures. The number before the W stands for winter and shows how easily the oil flows when cold, with a lower number meaning better cold-start flow. The number after the W shows the oil's thickness and protection at high operating temperatures, with a higher number meaning thicker protection when hot. So 5W-30 flows well on cold starts and stays stable at engine heat. In Miami, the high-temperature rating matters most because of our intense climate, but most cars still use the exact grade the manufacturer specifies year round. Using the correct viscosity keeps your engine properly lubricated and efficient. Motoro Cars' ASE-certified technicians always match the right viscosity for your vehicle.
