@apollo18 - the math is still way off, and specious.
Even if your “2oz” calculation is correct (and I don’t think it is), that doesn't mean there is almost no difference across a temperature range. The dipstick “tool” on the Mercedes 722.6 has two ranges - 20C (cold) and 80C (hot).
The range for each is about 1cm. But the two markings on the tool are about 3cm apart. The fluid, over 60C, expands enough to raise the level by over an inch.
So, it’s not a matter of a couple of oz if you get the temperature wrong, it’s more like half a liter to a liter. “Close enough” is good in horseshoes and hand grenades, but not here.
Follow the factory procedure for your car, stop overthinking this, because you’ve now made three separate threads with the overthinking, including using the wrong fluid, when to change the filter as part of a fluid change, and now this.
But your car is no better off for all wandering through the wilderness.
