So just crested 20K and had the third oil change done - first at ~8K (no UOA), second at ~14K, now at ~20K. Doing them a bit early b/c we've had enough service campaigns/recalls to warranty more frequent dealer visits and it's a convenience thing for me. I'm probably going to stick with 7.5K OCIs which is about 1 or 2 changes a year and will DIY (unless it needs to go back in) the next one with Liquimoly Leichtlauf High Tech 5W40 (and add Ceratec) to keep it consistent with my Golf. All have been done with dealer Castrol 5W40 and factory filters (note they list Mobil 1 0W40 on this one - that was a mistake on my part). I haven't had much oil consumption but did add ~1/3 qt of oil this go around (that was where the M1 0W40 came from). Funny - when I got it home from the service visit I checked it (always!) and it was almost 2/3 qt low (I like it at the top of the range)...slackers! I run only Top Tier 87 gas (mainly Costco...so cheap). My total annual mileage is about dead-on 10K so not a high-mileage vehicle - I'd say I have an 75/25 city/hwy split. I also have run a K&N filter since nearly new. Seems to be doing fine.
