2021 Tesla Model S — first used-oil analysis: what matters?

Charge curves lie if you don't match starting SOC and temp. Match starting SOC and battery temp if you're comparing 2021 Tesla Model S charge sessions. That's where I'd start. Take it or leave it — that's what I'd do. Heat soak after errands is the other window.

I'd treat 12V warnings as a no-ignore. On the 2021 Tesla Model S, I'd get the 12V/DC-DC side checked even if the traction pack looks fine. Then you'll know the next fork. On “first used-oil analysis: what matters,” that was the fork that mattered for me. This is from a 2021 Tesla Model S in Brooklyn with 81,000 miles. I'd want a dollar figure or a measured spec, not 'should be fine.' I keep a notes app thread for this now.
