Should I flush my engine before switching from conventional to synthetic or vice versa?
No. Engine oil system flushes are not recommended and could cause engine damage.


Is it true that new engines need break-in periods using conventional motor oil?
No, it is not true that new engines need a break-in period using conventional motor oil. New engines can be run with conventional or synthetic motor oils while still properly breaking in the engine components.


Do I need a special oil filter for a synthetic oil?
No, you do not need to use a special filter for synthetic motor oil. The type of oil filter used isn’t necessarily based on the type of oil, but rather on vehicle specifications. Always use the quality of filter that meets the specifications denoted in your owner’s manual.


Does my vehicle require a specific amount of motor oil?
Yes, your vehicles owner’s manual will contain information pertaining to the oil specification and capacity for your engine.


Is there a way to tell if my motor oil needs to be changed or is running low?
Yes, you should periodically check your vehicle’s motor oil dipstick for your oil levels. If your vehicle does not have an oil life monitoring system, change the oil per owner's manual guidelines. If equipped, your vehicle’s oil-life monitoring system will inform you when your motor oil needs to be changed, or, at a minimum, once every year. For more information regarding vehicle specific oil life and appropriate oil levels, check your vehicles owner’s manual.


Will using synthetic motor oil extend the change period as shown by the oil life monitor?
No. The oil life monitor is impacted by factors such as engine revolutions, engine temperature, and miles driven.


• Your motor oil must be changed regularly.


• Replacing dirty oil and filters can help protect the inside of your engine from premature wear.


• Use the recommended grade of oil for your vehicle as found within your owner’s manual.


• Follow either your vehicle’s oil-life monitoring system or your vehicle owner’s manual recommended oil change intervals.


• Check your dipstick at every fuel fill for oil levels and color. For the most accurate reading, wait a few minutes after turning off the engine to give the oil time to drain from the crankcase into the oil pan.
