So, I changed the oil in my 2015 F250 6.7 diesel and accidently put in about a quart to much! I can easily drain out a little, but, was wondering if that is necessary with only a quart over?

 

Not good to overfill oil. Pain in butt to drain out a quart of oil. you have to remove the plug and guess if you drained out enough. You do need to take the extra oil out

 

An easy way to do that is a pump that sucks it through the dipstick tube. Think they sell a cheap one at Wal-Mart for around $15.

 

Best way is what Tom said or as an alternative I would take the oil filter off.

If you remove the oil pan plug that oil is going to come out with a lot of force.

 

Typically you find them in sporting goods with the boating stuff. Comes with 1/2" and 1/4 plastic tubes. Just put the 1/4 down the dip stick and start pumping.

 

I added a half a quart too much on my last oil change. Just loosened oil plug let a little out and screwed it back in with no problems.

 

The only issue with removing the oil filter is the o ring. When I've changed oil filters, especially, Canister type, when the o ring is included and haven't...I've had an oil leak there. Granted, theyve been through many heat cycles unlike your situation but still, something to consider.

You might also consider a Fumoto valve when next oil change comes around. I really like mine after using it several times and would be an easy fix in this situation.

 

Yeah, I just loosened the drain plug (did not remove it) until I got a nice little stream and drained off about a quart. Whole thing took about five minutes to do. Me asking if a quart overfill would make any difference was just me being lazy and hoping not to have to crawl back under the truck! Thanks for all of your responses!!

 

 

You can remove the glow plugs and turn the engine over by hand with a breaker bar. Do NOT bump the starter to try to clear the cylinders - turn it by hand. They're under the valve covers so you have a bit of a task coming.

How much oil did you put in it? I would think it would have to be more than double the normal amount to get enough oil through the CCV into the intake. Hydrolocking is not typically an oil problem, but I guess anything is possible with enough oil.

 

Check the dipstick. If the oil level is still within the dipstick hash mark range, you will be fine.

Most engines are designed for the oil to sit in the middle of the hash mark area on your dipstick, when filled to recommended levels, and you are checking the oil cold. The idea is that as the miles accumulate, you may burn off or leak some oil, and then add a quart here or there. The dipstick hash mark area indicates that fluid level is adequate for operation. From the middle, you can be a 1/2 quart to a quart low or high, which will bring you to the top or bottom of the hash mark.

In my car, owners manual says 5.7 quarts. I've always added 6 quarts, because I don't want to store that 1/3 quart of oil or waste it. No problem. Oil is just a little higher than the middle of the hash mark range, but not at the top. In my truck, the owners manual says 6 quarts. The Honda takes 4.5 quarts. I always take that extra 1/2 quart left over from the Honda oil change, and pour it right into my truck so that it doesn't get wasted. 1/2 quart extra barely makes a difference when I look at the dipstick. It's still well below the top of the hash mark range.

 

Fumoto valves, by their very design, leave about 1/4" to 1/2" of used oil in the bottom of the pan. I'm a little uncomfortable with anywhere from 1/4 quart to 1 quart of used oil not being drained at every interval. Yet, I know plenty of guys who love using those Fumoto valves. Oil changes are so easy, that if you're really worried, you change your oil a little more often.

I'm still on the fence. But since I have already spent good money on magnetic drain plugs, I don't want to spend more on a drain valve. There is also another brand, EZ Oil Drain Valve, which looks exactly the same. Stahlbus has a different design which I like better, but cost twice as much.

Fumoto valves allow you to take a little sample and send it in for used oil analysis. A friend of mine installed a Fumoto valve, took a sample at 5,000 miles, then took as sample every 1,000 miles. No science here, but with his car, he determined that 10,000 miles was the point where the oil should be changed. The way he worded it was that the oil was still good enough that he could have used it longer, but it was beginning to degrade to where he felt that new oil would be better. Whatever that means.
