You've had OLM for years. Why hasn't my dealer told me about it and why all the fuss now?
As you can imagine, when changing from a 35-year-old traditional approach that is marketed by some very large companies, people will resist the change. Until the 2004 model year GMOLS was only available on select vehicles. Since the system was only on select vehicles it's been a little difficult for dealers to fully explain to customers so they stayed with the conservative approach. By putting it on the majority of the portfolio and simplifying the maintenance schedules we believe the benefits to the consumer and environment make this a change worth talking about.
Do I have to check my oil level now that my vehicle is equipped with the GMOLS?
Yes, the system does not sense oil level. As stated in the owner's manual, it is recommended that you check your oil every time you stop for gasoline.
