Oil Change Disaster, what did I do?

Ok, so I'm think cars just won't ever be my thing, but I'm just trying to be able to do some basic maintenance....

So I attempted to change my oil and I thought I was doing everything correctly, but I'm in quite a spot now. I drained my current oil, which was filthy despite still being only 2500mi into my last oil change. I left the drain plug out and pour 5qts of some Dino oil I bought just to try to get out any extra gunk and dirt, etc... I didn't watch the drain the entire time but do remember thinking it took longer when I drained the older oil. I put the drain plug back in and change the filter and put in 5.5qts of synthetic stuff I spent the extra cash on.

My dipstick says I am wildly overfull but I shouldn't be at all. To make matters worse, before I can figure out what is going on I need to move the car to get at my snowlblower. When I start to move the car it seems like it is struggling and I need to give it more gas than I should to get it in reverse and moving. I get out of the garage and see smoke coming from the exhaust and turn the car off immediately. I see oil dripping and I open the hood and I can see oil has spit itself out of the dipstick and made a little bit of a mess, but not terrible. Oil in the alternator doesn't look great, but there isn't that much of it and I was able to get a bunch up with a rag. I grab my drain pan and can tell it doesn't have 10qts in it, put it under the car and pull the oil drain plug. Nothing comes out, the oil pan is empty but I think there is over 6qts in my crankcase.

Double checked I am using the correct filter, inspected the changed one, it had some dirty oil in it, but nothing else I could notice. I put another new filter on as I dropped that one in the snow face down, but haven't start the car since.

I've done some searching and have found some terrifying stuff about what can happen when you overfil your oil and run it too long, as well as some horror stories about people driving with no oil. But nothing seems to fit my situation.

I'm going to call and get it towed tomorrow and get a pro to take a look, but I've gone over my steps repeatedly and have no idea what I did to make the dipstick overful and the pan empty. I was pretty meticulous about making sure the foil wrapper was totally off of the oil jugs I used, but I feel like the only thing is that I somehow clogged the oil flow, but feel like that is a long-shot.

Any ideas what I might have done / what kind of shape I'm in here?

Thanks,
Mike

Did you drain your transmission and not the engine oil? Sounds silly but I've seen it happen. That could be why you had trouble moving the truck, transmission slipping, and also why you're so over filled with engine oil.
 
I tried, as soon as I saw the smoke I shut the car off and put my pan underneath and unscrewed the drain plug, nothing comes out and I can tell the oil pan is empty. I'm sure I put the oil in the correct place and the dipstick is showing that it's more than full, but the oil pan is empty.
 
Right, that goes along with what i'm saying. You drained the transmission pan not the engine oil pan. You then dumped fresh engine oil into the engine. That's why the engine is overfilled and the "oil pan" is empty. You pulled the wrong plug out, transmission pan, not engine oil pan.

I'd have to agree that's the most logical answer. Either that or the new motor oil has found a way to defy gravity.
 
pretty sure you just did't wait long enough for old oil to finish draining, and then put all 5.5 qt in, which you should never do, always put 1qt less than the factory spec then check.

Also if the dip stick says its way overfilled why would you even drive it?

Edit: if you drained the atf and double filled the oil, you need to get away from your truck. leave it to the pros before you do anymore damage.

Yup, you drained the trans pan. You have a low transmission fluid level and 11 or so quarts of oil in the engine. Unless you filled the engine oil into the trans.
 
What I would do is buy fresh transmission fluid, it was so dark because it wasn't engine oil with 2500 miles on it, it was old dirty transmission fluid. Fill the transmission properly, drain the engine this time and fill with fresh oil, now you've got fresh transmission fluid and engine oil. Not a bad thing, look at the positives. You learned something and likely didn't do any harm to anything since you realized there was an issue and shut it down right away.
 
Could be I drained the transmission fluid not the oil, probably the most likely scenario... Will look into it and get back to you.
 
I'm gonna have to go with the general consensus that you drained the tranny pan instead of the oil pan. If the pan you drained was pretty much in the open and towards the middle of the vehicle, then you drained the tranny. Maybe that's why you thought it looked pretty dirty when coming out? Check your tranny dipstick tube (located near the passenger side firewall with orange handle).

The modern American male in action. Did I guess the gender correctly? I cant wait to see how this comes out.

Ever hear of youtube?

So you have 18 qts of oil in the motor. You are good for a year and half.

Now, now Dr. Coffee. You and I both know with how America is these days it's not polite to assume genders. :rolleyes:
 
Definitely drained the trans fluid and have about 15-16 quarts of oil in my car. Going to take your guys' advice and refill the trans fluid, drain ALL the oil, then refill the oil. Not sure if I should still get it towed and checked out by a pro, I've read about the crank aerating, but have no idea how to tell if that may have happened.

At the very least I should probably try to clean the engine compartment, there is definitely a little bit of oil in the coils of the alternator which I'm guessing could end badly. The rest of the oil I wiped off the belts and pulleys. Problem is that I'm just outside Chicago and it's cold out, to cold break the hose out.

Thanks everyone for the help and (most) of the kind words, I feel pretty stupid but you learnt he most from your mistakes I suppose.

Thanks,
Mike
 
No need to have it towed. Make sure you get the correct transmission fluid, not all transmission fluid is the same, I have no idea what the 3rd gen uses but i'm sure someone will chime in. Also hopefully someone will chime in with roughly how much the pan holds so you know how much to buy. Drain all engine oil, fill it properly, and you should be all good to go.

Everyone makes mistakes man, whether they admit it or not. At least you learned a bunch of stuff, good luck with the cleanup!
