I've been running the Rotella T6 in my DCT for the last few changes, but I don't like the inconvenience of it only coming in 1 gal containers. While in Wally world going to pick some more up, I noticed the the Mobil 1 0W-40 European Car Oil comes in 5qt and is not energy conserving. I decided to try it and It seems to work great. At least while the oil is fresh, the DCT is shifting the best it has since I've had the bike (new). It has 44.5k on it now. This is not an oil thread, just a thread to let you DCT guys know of another choice, not that it is better or worse, only that it works and comes in 5 qt containers.
