Hi guys, Newbie here and got a question. I have a 2007 4runner v6 2wd. It has 112k and I've put about 15k on it since I got it. I drive about 15-20 miles round trip to work each day (60/40 highway/street driving). Previous owner always used conventional. Last oci I used chevron supreme 5w30 that I bought from costco with a toyota oem oil filter. I live in southern California so I don't see much crazy weather. I notice that the car consumes oil down to the halfway mark on my dipstick between full and add (which I assume is half a quart) during my 5k oci. My questions are: 1. Should I stick to my current CS/oem filter? Or should I change it up? Suggestions? 2. Should I be concerned with my oil usage? I haven't heard many people complain of usage on this 4.0 engine so it makes me wonder if there's an underlying issue. Thanks in advance for the help!
