I was surprised when taking delivery of my Calligraphy that the complimentary dealer scheduled maintenance for an oil change was set at every 8000 miles. I owned a 4cyl. turbo charged vehicle previously and always changed the oil at 4000 miles. Turbos are known to be hard on oil. After looking at the Bluelink app, I noticed that the 8000 mile oil change interval was predetermined by the dealer based on my driving habits/conditions?There is a drop-down tab on the app that you can select your driving habits and conditions which will determine the mileage intervals for oil changes. The dealer did not inform me of this feature & by making changes on the app you can schedule oil changes to every 3000 miles if necessary. Just wanted to give everybody a heads up to take the time to input your driving conditions on the app to set the correct oil change intervals. I’m giving the dealer a pass on this misstep for now but I will be paying closer attention going forward. Thanks
