Engine oil overfilled- best way to drain a quart?

[Flyer]

I finally screwed up on the oil change. I put in (V8) almost 7 quarts and it looks really high on the dipstick- over an inch above the max mark. I'm surprised but maybe I did not let it drain quite long enough and only 6 quarts of so drained out in total.

I'd like to drain maybe half a quart out. I don't think I can do that via the oil drain plug (would be my preference) since the oils just gushes out of there and I am not sure I could get the train plug back without an insane mess all over the place. If I take the skid off and maybe take the filter out and drain it, that could be enough. I could do the filter thing twice too- by reinstalling, running the engine, and draining it again.

Is there an easier way, or am I stuck with one of those methods?

I bet you wish you had a Fumoto in that baby about now.

Dammit. I thought about that around an hour ago!! :ear:

I'll drive it once tonight, let it settle, and check again in the morning.

So I always check the side with the two bumps but why does the other side always show higher (but not solid)?

Anyway, worst case, I play with the oil filter since I don't want to waste too much fresh oil. I also thought about trying to suck out a quart with a thin fuel line but I'd prob have a heart attack.

my v8 take JUST under 7 quarts.

Did you change the filter out as well or just oil change?

I changed out the filter too. That is why I was a bit surprised. I started the 4R and put it back in the garage, let it rest an hour, and then checked. Anyway, I drove it last night for maybe 6-7 miles and will check it again this morning before doing anything. I'm hoping it was just a fluke. I still have a quart left so I definitely put 7 and not 8.

You could go the drain the filter method, probably two times to get enough out. Or, just drain the pan into a clean container, and then refill to the proper amount necessary.

This is a bit strange. I had started it and let it run for 3-4 mins to inspect for leaks. It showed very high for hours after. I actually drove it last night and checked it this morning. The level was just under the max line. I guess all is okay. Next time, I'll just put 6 quarts and then top up the next day. I was about ready to do the filter thing twice. I am considering the Fumoto valve but read a few reviews of them leaking slightly. That would make things easy. My skid is slightly warped so the filter change is the PITA.

For future reference the easiest and cleanest way to drain a quart (or two etc) is to 1)take off the oil fill cap
2)get a shop vac(and a friend to hold it in place) put a rag over the hose and press the hose on the fill hole
3) loosen and remove the drain plug
4)remove the shop vac to drain desired amount
5)replace shop vac to stop oil flow
6)replace drain plug
After about 7 yrs in a shop I found that to be the best way to do things without making a huge friggin mess

So the shop vac basically creates enough suction to stop the oil from flowing out of the drain plug?

 

[85straight]

Yes exactly

Wait for my next story where the shop vac was too powerful and sucked up all the oil, and I end up below the minimum line.

That's partly what the rag is for...reduce the pressure a little and ensure no oil gets into the shop vac. The shop vac would need to be very strong to actually pull oil out of the motor

Best advice I can give after working with my father who has been a tech for over 35 years and I am also into cars. Anytime you do an oil change, fill the vehicle with 4 quarts. That's your starting point. That would be your minimum. Add from there so you never overfill. As far as removing oil, there are suction devices that remove oil from the dipstick.
