Does this car have an oil to water heat exchanger? I’d be concerned with leakage there. May want to do a used oil analysis.

12oz though is really small. A gallon is 128, IIRC.

Do you smell it underhood when the engine is hot? I’ve had cars that didn’t really lose any, but you could smell that antifreeze odor from the miniscule weeping.
