Same with my brothers car….happened once and never again. Whether its a break in period or what I believe to be something with the way the sensor is reading the oil levels and the CAN system translating it to low oil, the issue has never happened again. When my brothers car had this issue happen the one time, he topped it off with a quart, and at the following oil change, he had quite a bit of “extra” oil that drained out. Just telling you what we experienced.As I noted above, I've only had the warning once just over 2500 miles, which I consider normal during break-in. I know I'm in the minority, but I'd consider this normal (every 2500 - 5000 miles) for any M or "M-lite" motor. My M3 did this and I put 120k miles on it with no other issues. Much like the Supra, I drove the piss out of that thing. Just remember these aren't Camry or Tacoma engines. I've decided to do a change to 5w30 before a track event coming up in early July and I will let folks know if the "problem" persists.
What 5w30 are people running for track use?
EDIT: Was just doing some reading on this and all of the benefits for 0w20 seem to be cold climate and environmental, and 5w30 is noted as reducing oil consumption and better for high temperature (like track) use: https://www.garagechief.com/0w20-vs-5w30-explained/. I really think Toyota decided to use 0w20 to meet or better environmental regulations and it's causing problems for their customers. I'll see how much blow-by I drain out is my AOS in a couple of weeks before the track day.
