Yeah that seems to be the majority who post they have to refill early. I wonder if the low loads and reduced RPM make the engine not seal up right. The oil is so thin from factory, I wonder if it's escaping.For the break in period I followed what was recommended by Toyota. Haven’t even launched it. There were a few spirited drives but nothing crazy.
I did a hard break-in and my level stayed at full. I also changed to a thicker 5W-30 to reduce the chance for blowby even more.
When I had an STI the same thing happened. People who took it easy during their break-in had oil issues and the ones who did a hard break-in had nothing.
