So we bought a CPO GS 350 and it comes with 20k miles /2 years of service. When we bought it, it had around 23k miles, so do we go in for the scheduled 25k service or go in at 28k since it's the 5k, 10k, 15k, and 20k that the service package comes with?

During the Cpo process it shows they changed the oil so I'm a bit confused. Thanks.

 

Call your Lexus dealer and ask them. They are responsible for providing the warranty service.
