what happens when too much oil is added?

typer142 · 17th April 2009, 01:07

i just had an oil change at the dealership and now it says too much oil. the car now stutters when i blip the throttle to 2000 rpm! the service tech insists its normal even though i tell him i didn't feel this ever before! he empties some oil, but it still stutters the same way. do you know what is actually damaged when there is too much oil so i can tell this idiot mechanic what to look for?!
also there is a new noise (soft hum) when at idle ever since this happened. any idea what it could be?
the car is back at the dealership and i wanted some advice from this great forum because i really dont trust this dealership after this incident.

thanks in advance!

How much too much? 1.2 or 1.3 will not be an issue. Much over that IS a problem per the BMW manual.

Need more info...any messages?? How much over?? Like Foggy said....give us the lo-down,,,.....

it said 1.3 then when he emptied some oil it now says 1. i really want to know what the stuttering is when i blip the throttle no more than 2000 rpm. it feels smooth when driving besides that. no engine lights on right now. all services say ok. engine oil says ok.

dealers suck

the car feels slightly worse now, its getting rough at around 3000 rpm. the dealership mechanic told me its not the engine because he had one tech rev the car while his hand was on the intake manifold and he didn't feel any vibrations. its really worrying me now. any ideas what it could be???

did you take a tech for a ride??? you must show them what your experiencing...is it under a load when it vibrates???is it a misfire??? misfires usually happen under a load....you drive them....

It has been an hour since his posts, do you really think he has any update?

OP You said it drives fine. 1.3 oil shouldn't off hurt anything.

If you are like me, perhaps you are listening too closely as a result of this experience. If there is anything major, you will get a light on the dash, limp mode, etc.

A short blip below 2,000 with no load will not be smooth.

Drive it until you get a real symptom or a light or symptom gets worse and try to put the experience out of your mind, it should be o.k....

it only vibrates when i rev it, and not when actually driving/engaged in first gear- it's a six speed. the tech says he's felt the same thing on other m5's and m6's however they were not as rough as mine. the reason i'm worried is because it never happened before the oil change was performed. anyway, i may visit another dealership and provide updates...
