Is it okay to delay an oil change by one month?

[StephenDella]

Delaying an oil change by one month will not have any impact. Below is an introduction to oil-related information: Semi-synthetic oil: If you are using semi-synthetic oil, it can be changed every nine months. If you are using fully synthetic oil, it can be changed every twelve months without any issues. In fact, 4S shops tend to over-maintain vehicles. Usage environment: The most significant factor affecting a vehicle's maintenance cycle is the oil. In practical use, the oil change interval is certainly related to the vehicle's operating environment. According to the national standard "Gasoline Engine Oil Change Indicators," whether the oil needs to be changed depends mainly on whether the following parameters exceed the limits: kinematic viscosity change rate, flash point, acid value, water content, fuel dilution, pentane insolubles, wear metal content, and silicon content.
