GM SERVICE IN WILMINGTON & MILLSBORO
GM's family of brands is the biggest single share of our work, with more than 720 GM vehicles through our two shops in the last two years. Most of them are Chevrolets (440+), followed by GMC (120+), Buick (80+) and Cadillac (50+). The ones we see most are the Silverado 1500, Equinox, Malibu, Cruze and Traverse, mostly 2003 to 2022 models.
Each brand has its own page: Chevrolet, GMC, Buick and Cadillac. This page is for everything in between, including the GM brands that no longer make new cars. We still service Pontiacs, Saturns, Oldsmobiles and Hummers. They were built on the same GM platforms as Chevrolets of their era, so the same know-how carries over.
The work GM owners bring us most is oil changes, check engine light diagnosis and tires. GM gasoline engines from the 2011 model year on call for a dexos-approved oil, and we check the exact spec for your engine before every oil change.
