Synth may be able to get this life, but it is a bit of a gamble unless you either do an oil analysis to determine if and when it is due or have an oil monitor built in (9^3SS). In the US, we seem to take shorter trips which shortens oil life. There have been a number of 2.3L engines which have suffered from sludging. Whether or not it is due to poor Dino oil or just due to driving style, I do not know. This was not historically been a problem with the T4 and the only change I can attribute it to is the 10k oil change interval. I just would not stretch it that long without oil analysis to corroborate it. Therefore, I change my Mobil 1 at 5k...
