Here in Canada we have service 1,2,3,4. I have 29000km or 18000 miles on my ride. About 1.5 years ago I had a "spring special" which I was told was more than a service 3. Now with about 15000km more on the odometer I inquired about a "fall special" and they say its not as good as a service 3. The car is 31 months old, If I go with a lesser service is the dealer going to void my warranty. I am just asking because my car has about a years worth of driving.
