The frequency of your oil changes depends on the model of your car and how you drive. Generally, most cars should have their oil changed every 5,000 and 7,500 miles. You should however check your auto's manual for guidance.
The Check Your Number widget’s “number” is the manufacturer-recommended oil change mileage interval for your car, based on normal driving conditions. The actual oil change interval may vary depending on various factors, such as driving conditions and habits, the condition of the car, and the type of engine oil applied. Some vehicles are equipped with an oil life monitor that alerts the vehicle owner when it is time to change their oil.
"Normal driving conditions" DO NOT include the following:
• Cold weather, less than 10 degrees • Extreme heat, more than 90 degrees • Extreme humidity • Towing a trailer or hauling heavy materials • Repeated short-distance trips of less than five miles • Extensive idling or in stop-and-go traffic
If you do drive in any one of these conditions in a typical week, you could be driving in severe conditions, and may need to change your oil more often.
Regular (Conventional) v. Synthetic Engine Oil
Almost all oil change interval “numbers” found on the Oil Checker websiteare based on using regular engine oil. Some makes and models require using only synthetic oil for their engines. Synthetic oil can help your engine last longer, and allow car owners to go even longer between oil changes –up to 20,000 miles.
Please consult your owner’s manual or dealership for information on the oil change interval and engine oil best suited for your vehicle(s).
