Finally, it forms a seal between the pistons and the cylinder walls, maintaining compression and ensuring the engine can generate the power necessary to perform work. Always refer to the equipment manufacturer's recommendations, as using an incorrect viscosity can lead to poor performance, increased wear, or even engine damage.
4 Cycle Oil for High Altitude: Viscosity and Performance Tips
The number after the dash represents the oil's thickness at the engine's normal operating temperature. Finally, rust and corrosion inhibitors protect the internal metal surfaces from moisture and acids produced during combustion, ensuring the engine remains in pristine condition long after the oil is drained.
Conventional oil is refined from crude oil and provides a reliable and cost-effective form of protection. The "W" stands for winter, indicating the oil's cold-flow properties; the lower this number, the easier the oil flows when starting in cold temperatures.
4 Cycle Oil for High Altitude Use and Viscosity Considerations
While more expensive, synthetic oil is often recommended for high-performance equipment, engines subjected to severe duty cycles, or for owners seeking the longest possible engine life. Choosing the correct viscosity ensures the oil can reach all components quickly on a cold start while maintaining enough thickness to protect the engine under high load and heat.
