well, i am about to start filling a quart extra in my car while doing oil changes, it can only be good for it.

    Too much oil is worse than less.

      its clearly not, you can fill twice the amount of oil required and nothing will happen as shown in the video.

          >>the crank slaps the oil and makes air bubbles
          if you have 3 times the oil required, yes
          filling twice as much, still doesnt make the crank slap the surface.

            inertia will make the oil slosh from one end of the pan to the other and it will still slap
            at least in my old miata if i overfilled it even a quart the crank would slap the oil while braking downhill

            That slapping would be very minimal and largely inconsequential compared to the more real danger of being in a long sharp corner and sucking air into the oil pump. It's very common for people tracking their cars or going out for spirited driving to add an additional quart to make sure their pickup is always wet. I've done it in my car for about 60k miles and never had issues with oil pressure

            Spec Miata guys do the opposite and underfill for weight reduction because the pickups are long enough

          This. From over a century of experience we know that this happens. Supposedly the pressure differentials with the air bubbles cause stresses on a small scale that adds up causing fractures and failures. This is something humans found simply from experience.

            the bubbles collapsing under pressure generates heat roughly equivalent to the surface of the sun which breaks down the oil faster.
            actually happens more often with water pumps and coolant but bubbles can physically damage metal parts.

        when you get crankshaft slapping the oil it will cause air bubbles to get into the oil pump which is abscence of oil
        also the crank throws hitting the oil steal horsepower.

        Probably going to depend on how deep the sump is, how the pump works and how useful the oil is after it gets stirred into a foamy, bubbly mess by the shaft.
        They also made that transparent oil pan by using the outer side of the original as a mold, which made it somewhat larger on the inside.

    maybe instead of nonsensically adding more oil maybe you should instead perform this:
    >get engine warmed up with reccomended oil level
    >jig the motor to run at 3.5k rpm
    >check the oil
    then you will know how much oil is infact in the sump while it's running, if you have a deep sump and most of it's still there then you are wasting your time, personally I just go half a quart over.

    I really doubt 1 extra quart will frick it up too much. But i wouldn't go nuts or you will frick it up. I either overfilled mine or set it at the right level because the damn dipstick is wonky. The level is actually higher when cold, against all known laws of reason

    Uncle Tony tells about when top fuel dragsters used to run wet sumps they'd just fill the sump nearly full of oil and all the oil would slosh to the back of the engine on launch and get pounded by the sump.
    Turns out it's not really a problem and he believed it actually help dampen crankshaft harmonics for those 100% stressed engines.

        Race engines still need oil pressure bud, in fact it is far more important for the race engine to have a constant supply of good oil than your shitty old 70hp/l engine revving at 3k.
        And yet even with a huge crank obliterating the oil at 8,000rpm the engine still has no oiling problems.

          as the post above you said, overfilling is more about ensuring the pickup is always bathed enough
          >pressure
          You're not getting any significant pressure difference from an over or underfill. Oil requires a 36.9 foot depth to gain one atmosphere absolute.
          The pressure gain from less-than-inches in a normal car engine, of an overfill aren't even worth calculating.

            >completely misunderstands the pressure argument
            They say that the crank whipping the oil will cavitate it enough to negatively effect oil pressure.

            >I'm too moronic to understand the difference between an engine that's only at load for 10 seconds vs one that's at load for potentially hours at a time

            Do believe that that the oil cavitation only occurs after several hours?

    Even if engine doesnt get damaged or seals blow to causing severe oil leak from engine oil overfill. Engine will have excessive oil burning causing prematurely ruining catalytic converter. Even small oil overfill can cause loss of power for the engine because too much oil will cause more resistance/load for the engine. I have done the mistake twice slightly overfilling engine with oil, it always reduced performance, unusually low idle rpm, weird fluid splashing noise so I removed the excessive oil and all issues disappeared.

    In the video they tested engine for minutes, completely different thing than running engine for above 1hour.

    I've always ran an extra 25% oil level in my track cars
    Basically essential on gt86/brz/gr86
    Miatas love an extra quart above full too
    Helps stop oil starvation in long sweepers
    Going anymore than ~25% overfilled will create a little foam and will reduce power by some insignificant mount (bottom end dragging through oil)
    On the road,dont waste your time/oil but if you track a wet sumped car, add a little extra oil

    I overfilled a mercedes automatic by about a quart (was supposed to take 7-8qt). as a result the fluid became agitated by the gearset, become airated and thereby stopped lubricating. within 500 miles the fluid was completely burnt and all of the clutches inside the transmission were dead.
