Here is my most recent UOA for the 2013 RAV4. Definitely seems like the longer trips and the warmer weather are treating the oil better. Most of these miles were highway. I commute 120 miles round trip during the week and have some trips to New Jersey, Richmond, etc in there. The only strange thing is that silicon is still high. I did change the air filter at the beginning of this interval, so that could be some of it. I'm going to check the filter sealing and connections anyway. I refilled it with 3qt M1 0w40 and 2qt M1 EP 0w20 and a FU. It has definitely quieted the startup valve rattle quite a bit already, so we'll see how it wears. I'm going to do 14k miles this interval.
