I have the 2.5L and the recommended oil change interval in it is 10000 miles or earlier if the the monitor alerts you. I keep getting these postcards from the dealer telling me it time due to 3K mile, 5K miles/etc. I called the dealer when I got the first one and they told me that is computer automated cause they still service many cars that haven't gone to the new intervals yet. They told me NOT to bring mine in until the monitor goes off and that the 2.5L came with all synthetic from the factory and all synthetic is recommended for that engine.
I am at 5600 right now, really feels weird to not be taking it in, but I am going to go with it or I will just go when they send me a coupon sometime after I hit about 7000, which they will cause I get them regularly, and it is easy for me to do so. I also asked my normal mechanic about about it and he also told me to just do whatever the monitor said since its all synthetic and the engines today are just so different and stop worrying about it...
Just information, certainly no recommendation. If I ride it out till the monitor comes on I will report what mileage that was....
