OIL CHANGE ANSWERS

WHEN SHOULD I CHANGE MY OIL?

VEHICLES WITH ENGINE OIL LIFE SYSTEM

Most GMC vehicles are equipped with the engine Oil Life System (OLS). This system interprets your vehicle’s speed and engine temperature and continuously monitors operating conditions—which helps determine when it’s time for an oil and filter change.

The OLS also monitors driving conditions to let you know precisely when to come in for an oil change. When the OLS light comes on, you know it’s time for service. It’s designed to be an accurate, effective way to help you save money and reduce oil waste.

Your Certified Service technician will reset your Oil Life System after an oil change. If you would like to reset the system yourself, ask your technician how, or consult your GMC Owner’s Manual if necessary.

VEHICLES WITHOUT ENGINE OIL LIFE SYSTEM
Consult your vehicle Owner’s Manual for the manufacturer’s suggested oil change interval. Engine oil can also break down over time, so even if the specified mileage has not been reached, auto manufacturers will recommend changing every year or so. Again, check your Owner’s Manual for the specifics for your vehicle.

HOW DO I CHECK MY OIL LEVEL?

It’s a good idea to periodically check your oil level. In order to get an accurate reading, engine must be off and vehicle on level ground. Accuracy improves when checking a cold engine (off for two hours) prior to starting. If unable to wait two hours, the engine must be off for at least 15 minutes if the engine is warm, or at least 30 minutes if the engine is not warm. Always consult your GMC vehicle Owner’s Manual for the proper procedure to check your oil level. You’ll get a more accurate oil level reading on the dipstick by following these instructions.

 

WHAT ARE OIL CHANGE WARNING SIGNS?

Keeping an eye on oil level and other measures of your engine’s oil is critical. Lack of proper engine oil maintenance can damage the engine. Below, you will find a number of indicators that can help you prevent damage to your engine.

“Change Engine Oil Soon”
When the “Change Engine Oil Soon” message displays, an oil change service is necessary for the vehicle as soon as possible, within the next 600 miles. If driving under the best conditions, the engine Oil Life System might not indicate the need for vehicle service for more than a year. The motor oil and filter must be changed at least once a year and the engine Oil Life System must be reset. Your dealer has trained service technicians who will perform this work and reset the system.

“Oil Pressure Low/Stop Engine”
Low engine oil pressure can cause extreme and costly damage to your engine. If low engine oil pressure is indicated, safely bring your vehicle to a stop and do not restart your engine until the proper engine oil pressure is restored and the cause of the drop is corrected. You should check the oil level immediately. DO NOT operate the engine with the oil pressure warning light on or an ENGINE OIL LOW ADD OIL message displayed.

Oil Leaks
One of the most immediate signs of an issue with your oil is noticeable leaks. If you detect a leak, address it with your dealer as soon as possible. Catching a problem before it is truly an issue can help save you time and money.

SHOULD I STILL CHANGE MY OIL EVERY 3,000 MILES?

The majority of today’s Chevrolet, Buick, GMC, and Cadillac gasoline powered vehicles are equipped with the engine Oil Life System which allows to oil condition to be closely monitored. Depending on the age of the vehicle, driving habits, and road conditions, vehicles with today’s advanced engines and oils may be able to go longer than 3,000 miles between oil changes. It’s a good idea to check your motor oil level regularly.
