2018 Mercedes-Benz GLS-Class Oil Change: Specs & Service

The visit also includes resetting the oil-life monitor and checking underhood fluid levels.

The service is relevant across the model's 3.0-to-5.5-liter V6 and V8 engine range.

Drivers may notice an oil-change reminder, dark or low oil on the dipstick, or a ticking or louder engine note at startup when service is due. Book through the service scheduler or call Mercedes-Benz of Draper at 385-425-5461.

Driving conditions can influence how hard engine oil works. Cold starts require oil to move through the engine promptly, while stop-and-go traffic and towing can increase operating load and heat. Dust exposure can also place greater importance on keeping the lubrication system and filter service current.

When an oil-change reminder appears, the mileage passes the last service point, or the engine sounds louder at startup, schedule an appointment. Use the service scheduler or call Mercedes-Benz of Draper at 385-425-5461 for directions and booking assistance.

Service includes draining the existing oil, refilling with the specified grade, installing a new oil filter, resetting the oil-life monitor, and checking underhood fluid levels. The service interval is determined by the vehicle's maintenance guidance and operating conditions rather than by how clean the oil appears on the dipstick.

Cold starts, towing, stop-and-go traffic, and dusty driving can increase the importance of consistent maintenance. Bring your 2018 Mercedes-Benz GLS-Class to Mercedes-Benz of Draper in Draper for an OEM-spec oil change — schedule service.
