I just learned more about car engines from this guy in 3 minutes than anything else I’ve ever seen on youtube combined

i just can't imagine someone can "drain a little" ... If you ever changed oil you know once the screw is out from the oil pan, its flowing really fast, and its not an easy job screwing it back while oil is rushing out not to mention that it will sprinkle everywhere, even at your face lol. Maybe removing the oil filter you can pour out a little oil from the filter thats enough to be at the proper level, then put back the oil filter because removing the oil filter will not drain every oil, only what remaining in the filter

0.4 qts is not going to hurt. More than a qt is getting bad.

I inadvertently overfilled my Infiniti FX45 by a quart yesterday. Got a ton of oil smoke out the tailpipe. Luckily I had just installed a Fumoto oil drain valve a few days ago so all I had to do was put an empty bottle under the valve, open the valve and drain out a quart. Closed the valve, checked the level, good to go.

it does not always lead to severe foaming and it is worth keeping in mind that even foamy oil tends to have the bubbles removed during the oil pump action on the oil where it is pressurized. Also, some engines have a margin of error in the distance between the extreme reach of the crankshaft and the top pf the pool of oil, so some safety margin is thereby built in. It is notable that modern oil formulations also tend to control foaming. Overfill is most disadvantageous in terms of the power loss of that crankshaft spinning in and oil pool, if the pool is too high then real damage may happen to the iron of the crank or block.

The most common "slight" overfill usually results from failing to change the oil filter but then adding the correct amount of oil specified, I have in the past caught several garages out on this by returning and showing them the pre marked filter with its old date marked on it.

I love these type of videos. More Cooley is the best

Awesome!Very informative👍🏼I overfilled by a half a quart and noticed a leak on the oil pan gasket. I’ll be doing a new oil change and new gasket

[mr.iforgot]

That makes complete sense. Tomorrow morning I will check my engine. I forgot to replace the oil filter last time and I added the 5 quarts. Not thinking that the filter has 1/2 to 3/4 of a quart in it already. Yes, im aware not replacing the filter can result in it getting clogged. I spaced out and forgot.

Cooley chose to say “Toronto, Ontario” ! Not “Toronto, Canada” - Thank You Cooley!

Hi Cooley,

I always see a crown vic on your videos. What are upgrades or changes have you done to it? I bought a 2011 grand marquis and I am just looking for ideas.

Thanks

Omg easy and simple. My neighbor told me you don't have enough oil. So stupid me went to the store bought 6 quarts and filled it up. He did not to told me to drain the old and replace it with new. Now the old and the new mix. Good luck Im driving soon to work...

[Tyler-vkdu]

Thank you so much i try to learn from many YouTube car mechanics, i have notcame across anyone who explains an showes the situation of the oil beingover filled. I filled the small Honda up for my grandmother. I found out to let it run for or more than2 min than check it.. When i did it was above the line about 1 to 2 CM. Its not too bad. I drove it the night before woth the same oil lvl an o drove it hard almost got the little toy Honda to 120. Poor car so old but very reliable if took care of. Gotta love Toyota.

I think I have found the best channel on YouTube

Ive seen overfilling oil cause excessive blowby and thus seals losing integrity...

I got some free oil changes when I bought my Chevy truck and always had to lift it and remove afterwards. Last year I had the radiator flushed at a local mechanic and also had the oil changed. Same problem. This year I did it and added the required six quarts. Overfilled. I tried the suction trick and it doesn't work for me so I gave to lift it and get covered in oil again. Next time I will add five quarts and top it off.

How much is too much ? Show me on the stick

[akdomun]

Thanks for the shout-out Brian! Very well put together!

I was told over filling would increase pressure inside the engine and would blow oil filter seal
