What will happen if I use 20W40 engine oil instead of 10W40?
Using 20W40 engine oil instead of 10W40 can potentially have some effects on your engine's performance and lubrication, especially in terms of how the oil behaves under different temperature conditions. The numbers "10W40" and "20W40" represent the oil's viscosity rating, and they provide information about how the oil flows at different temperatures. Here's what could happen if you use 20W40 oil instead of the recommended 10W40: Cold Start Performance: The "10W" or "20W" part of the viscosity rating indicates how the oil behaves at cold temperatures. The lower the number, the better the oil flows in cold conditions. 10W40 oil has a lower viscosity at cold temperatures compared to 20W40 oil. Using 20W40 instead of 10W40 might lead to poorer cold start performance, which can result in increased engine wear during startup, especially in colder climates. Oil Flow at Operating Temperatures: The "40" part of the viscosity rati
