Our SUV's fill plugs call for 85w-90, but the dealership sells 75w-85 only and the official service manual calls for 75w-90, so the heck with it. I'm going with Mobil 1 75w-90.

Let me start by saying that I decided not to upgrade to the 2013 version. I suppose some people will ding me for posting a review on a product I don't use. However, my decision is based on a long history of using Quicken, so hear me out.

I don't use activity trackers (as I really don't care how many steps I take or calories I burn), but this one is different. The swim tracking (although not perfect), does beat what I expected it to report. Also, the running mode shows how hard your feet are hitting the ground and reminds on technique (preventing injury from heavy foot strikes). Overall, it's a neat little gadget, and isn't obtrusively large like other bands.
