All you have to do is pay attention to one thing: your GM Oil Life Monitor (found on most GM vehicles after 2004). Garber Chevy will do the rest.

Your Garber Chevy Goodwrench technician will perform a Multi-Point Vehicle Inspection and take care of any maintenance your vehicle needs at that point. Common services include:

Maintenance I vs. Maintenance II
When you bring your GM vehicle to Garber Chevy Goodwrench for regular maintenance, we will likely perform one of two service packages – conveniently called Maintenance I and Maintenance II. We perform only the services that you need, depending on your current mileage and what services we did on your previous visit.

It's a lot like the dentist. Your dentist reminds you when to come in (just like your Oil Life System, if equipped) and keeps track of what work you need done every six months. Except when you visit Garber Chevy Goodwrench, there is absolutely no pain involved!
