I'm not surprised at all to see a 3.7Q requirement routinely filled with 4Q. Nature of the rounding error and the nature of oil coming in quarts/liters, except from maybe bulk dispensing lines.. which it would not surprise me are set to 1/4Q increments. Bulk dispensing lines have their own issues, mainly attention to detail on the part of the tech performing the service.I am surprised to say that my mechanic overfilled with oil when I had it changed recently. The level is at the top of the orange, or just slightly below, on the dipstick. I acknowledged to him that it holds 3.7 quarts and he eyeballed his container and added roughly 4 quarts. I checked it as soon as I got home. Also, I stood there with him and chatted about cars as he drained the old oil out. Yet, it appears that a portion of the old oil remained in the pan because the new oil is not as clear as the oil was that was in the engine when I bought it. He used full syn 0-20.
Is that too much oil and if so, is there an easier way to remove some oil other than dropping the pan and removing the drain plug?
In my view.. considering how many times this particular engine is overfilled both at the factory and at dealerships.. often by what looks to be a full quart... you have nothing to worry about. Honda has published a chart back during the big OD flareup in China showing that this engine is fine with an oil fill 22mm above the full mark... which appears to be ~1.5 over the full mark. Beyond that.. the engine will start throwing codes and making tuning changes to protect itself from harm.
