Fuel dilution is a problem on this engine, you need to remember that. I drive the heck out of this thing and fuel still showed up in a couple of my oil reports. In the last report, Amsoil looks thin although it is the thickest 0w-16(thicker than Mobil 1 ESP 0w-20) I know of. That means fuel. So you have to be very careful, specially in the winter. Maybe let the filter stay and suck the oil out every 2,500 oils?OP...have you used 0W-16 oil mostly? always? sometimes? please elaborate.
Glad to see this. I have a 2023 Rav4..low miles so far. It is a fairly complex engine.
