Nothing too exciting. I don't think I posted my previous UOA, so the 7/17 and 10/16 changes are new. As you can probably guess, I forgot to collect a sample during one of my changes (January 2016). The 8,259mi run was actually a blend of 1.5qt AFE, 3qt EP (both 0W20) and .5qt Supertech (5W20).
One thing to note, I did swap out the engine air filter half way through the 7,189mi run, which might account for the silicon (not that I'm worried). As of last year, the Element became our only vehicle, so it gets a lot more short trips when my wife commutes, mixed in with longer weekend trip. I do two oil changes per one oil filter interval. I put in 5qts of M1 0W20 EP back in. I'm trying to extend my intervals, but I usually just change it when time permits.
