Most vehicles need an oil change every 3,000–5,000 miles, but depending on how and where you drive, your oil can go bad early. If you notice any of the following issues, it’s time to get an oil change:

• The Check Engine or Oil Change light is illuminated
• You hear a knocking sound or other unusual sounds coming from the engine
• Your oil looks very dark and dirty when you check it
• You aren’t getting your usual gas mileage
• Your engine overheats
• You see oil leaking beneath your vehicle

Regular oil changes are vital to the long-term life of your vehicle's engine. Motor oil lubes the moving parts of your engine, reducing friction and heat. Over time, your car’s oil picks up dirt and debris and becomes less effective at keeping things running smoothly.

During an Oil Change service, the old, dirty oil is removed and safely disposed, and new, fresh oil is added. Proper adherence to your vehicle’s recommended oil change maintenance schedule will save you money and unnecessary repairs over time.

It depends on your individual car. A safe bet is to refer to the mileage on the windshield sticker from your last oil inspection and change it regularly.

It all depends on your individual vehicle. Check your owner's manual or call the auto repair center before purchasing your voucher to make sure you get the right type.
