Should I flush my engine oil before switching from conventional to synthetic oil or vice versa?

No, it is not necessary to flush your engine when switching between motor oils. Typically, conducting a routine oil change and replacing the conventional oil with a synthetic motor oil will not require any additional maintenance.

Do I need a special oil filter for a synthetic oil?

No, synthetic motor oil does not require you use a special filter. Oil filters are used based on vehicle specifications. Refer to your vehicle Owner’s Manual for guidance on what type of oil filter to use.

Is there a way to tell if my engine oil needs to be changed or is running low?

Yes, if equipped, your vehicle’s oil life monitoring system will inform you when your motor oil needs to be changed. Refer to your vehicle Owner’s Manual for more specific guidelines.

Does my transmission fluid need to be changed as regularly as my oil?

No, typically, transmission fluid lasts much longer than most engine oils. Refer to your vehicle Owner’s Manual to identify how often and when your transmission fluid should be changed. Severe usage and regular usage descriptions are provided.

Is there a difference between power steering fluid and transmission fluid?

Yes, there is a difference. There are many types of transmission fluid. GM Genuine Parts and ACDelco recommend referring to your vehicle Owner’s Manual for fluid recommendations for all vehicle systems.
