Question: What does adding too much engine oil do?
So.. sorry to bump an old thread, but I drained the oil from my ML 320 and and proceeded to fill with 5 quarts of oil. Well, turns out this was way too much and after driving for about 10 minutes the car started to make a weird clunking sound at higher revs, and it was holding gears a lot longer before shifting up... 1st gear to 2nd was okay, but would take a while from 2nd to 3rd and 3rd to 4th....
Whats the chances I've done some real damage here?
I did read the dipstick after fitting it, and it was over the red line by a fair bit, but I thought the engine just had to run through the oil, so I didn't give much credit to it, seeing as I emptied the oil already.... and I read that the engine thats 8.5 quarts. I only put 5... I was stupid.
There wasn't much oil when I drained... lucky to be 3 quarts.. It seemed strange to me why more oil wasnt removed when I drained it. Stupidly I paid no attention to it.
Can you guys give me any reassurance? I can't drain oil and test the car until tomorrow morning so I'm a bit worried.
I only drove it for 20 minutes.
I guess it's possible I drained the transmission... but the oil was black, not red...
I drained the plug at the front of the motor... ITs a hex key..
It was on the left side (if u were sitting in the car) under the engine..
I always had the idea that the transmission sump was further towards the middle of the chassis?
God, I hope I didn't do that..
It would explain the car not shifting though... shit.
if you can take a picture of the thing you drained (actually where you drained it from) it would help alot. When the transmission fluid is old on the 722.6 tranny it will look like old motor oil (like the first time I saw mine i thought it was oil)I just hope the engine is okay after... The noise didn't sound good, hope it subsides. I'm pretty sure the transmission will be okay as it was just a short drive. Shit
