I assume that is one quart/liter +/-.

You mentioned your dipstick showed down to the min level; that should equate to about one quart down. In ~2,000 miles, in your climate, I would not be concerned, esp with that 0W-20 you said the mech put in. Doubt I would run 0W-20 in any car, in any climate, except maybe the Arctic circle area.

You added a qt of 20W-50; I agree with posters that viz oil is pretty 'thick', though its detrimental effect on your oil fill is minimal, imo.

Fwiw, I run 0W-40 M1 for the past several years, as I prefer the low 0 for cold starts in our cold to coolish mountain climate, and the 40 aspect seems to be consumed less at my high rpm road speed with my short geared 5spd manual trans.

Oil threads are ubiquitous here...If I ran a car in your clime, I would run 0W-40, 5W-40 or maybe 5W-30. Get an oil change when you can, dump that 0W-20 crap, use a good brand of synthetic, make sure you/the tech does a full fill, and keep an eye on consumption. That's the best opin I can offer.

If you use a quart in a couple/few thousand miles, it is what it is, esp in your warm to hot clime, and none of us knowing 'how you drive'. Keep an eye for leaks under the hood, on the pavement when you park and the tail pipe. But, otherwise I would not worry about your oil consumption. Time and some observation on your part will be helpful in diagnosing as to whether you really have something other than 'normal oil consumption', imo.
