    So I checked my engine oil level twice since getting my used car (a week ago).

    It's difficult to read the level, does the oil ever turn brown/dark? As have driven it around 300 miles so far and on other cars I've owned, little old oil would of mixed in already making it darker.

    I haven't got any engine oil warning light but the dipstick reading did seem low from what little I could tell so topped it up a bit.

    How much engine oil should I expected to burn and be "normal" after 200,000 mile engine mark?

    Use a white paper towel. Remove the dipstick, clean it off, reinsert it, remove it and
    lay it against the paper towel. You should be able to see where the level is. You can
    also use a flashlight. When it's new oil, it's almost clear. It will get dirty by 5000 miles.

    What year is it? If it's a late 2014 or 2015, you likely won't burn much, if any.
    It also depends on how you drive it. If you drive it like a Prius, you won't burn as much.
    If you drive it like a F1 car, you'll burn more.

    4.75qt for an oil change with filter change. About 1qt from the full mark to the low mark.

    It's easier to read if you wait 5 minutes between first pulling out and wiping the dipstick, and reinserting for the check. I found the face towards front of car less "ambiguous". Especially when the oil's near-clear, tilting the dipstick till it's refecting light makes the the oil limit more distinctive. Personally, being very myopic, if I look at it up close and without glasses, much clearer.

    There is a small streak on the side "wall" of the dipstick but can't tell as it continues/spreads up higher. Yeah by 5,000 miles will be the next oil change :LOL: won't be any wiser.

    2014, yeah so far been driving it like a Prius in normal mode.

    Will give this a go, as I tried before a cold start, and then 5 minutes after driving (let it cool down a bit) but was of no success. Yeah there seems to be a smudge on the side "wall" of the dipstick.

    What year is it? (Your avatar doesn’t disclose this.)

    at least in North America, Toyota spec’d “low friction” piston rings, ‘til partway through model year 2014 (change happed at a specific VIN), which have proven prone to clog and oil burn. There’s a pair of TSB’s with more info, and instruction for piston/ring replacement (attached). Another solution is a new “short block” (everything between upper oil pan and head).

    according to the first (attached) TSB, one US quart or more oil consumption in 1100~1300 miles is “excessive”, at least to qualify for for piston/ring replacement.

    The catch though, to get Toyota to do it: car has to be under 60k miles. :rolleyes:

    anyway, get comfortable with reading the dipstick first.

    If you don't see any oil on the dipstick after it sat over night, there is no oil in the engine.
    Pour in at least 1/2 quart, wait a few minutes, check again. Keep doing that until it's almost
    to the full mark. Then drive the car for a few miles so the engine keeps running.
    Then park the car, wait about minute and check the oil level.

    The "streaks" on the side are nothing. You will be able to see oil, even freshly added clean oil,
    on the dipstick. You might have to move around to get in the correct light.

    If you want to be safe, use a clean pan, drain the oil, then use clean containers to measure just
    how much oil was in the engine. Then pour it back in and add what you need to make it 4.5 quarts.
    The filter holds about 1/4 of a quart of oil.
    Or just dump the oil and change the filter and fill with 4.75 quarts of oil.

    Colloquially known as a cup. ;)
    The Owner's Manual recommendation is 4.4 US quarts. To be fair, when I pour in the recommended amount, it's slightly low, say 1/8" below top mark. Which is fine by me.

    4.4 quart with filter change, and 1.6 quart (1.5 liter) from low to full mark, according to Toyota.
