Consequences of too much oil?
 

Had my MY99 Impreza Turbo serviced recently.
I now find that the garage have c**ked up and put in 6 litres oil!!!
Could someone give me the likely problems that this is likely to cause.

I think the oil will get sucked into the in take via the breather pipes. not a good thing as it will go all over your turbo and in the intercooler, lots of blue smoke me thinks.

First post -

Too much oil can mean the crank can slosh it all about causes heat from the friction and the oil loses its "goodness" quicker plus all the bad things about having increased temps (locally) plus other things that I am sure other people will come along and mention.

Just drain it yourself and fill with a quality synthetic oil. Don't use that garage again. No harm in giving the garage a call and asking politely if they will rectify the problem.

I suspect they won't and to be honest, I wouldn't let them near my car again anyway!

agreed

Foaming, crankcase pressurisation, flooding of breathers and oil separators with oil and oil contamination of inlet tract.

Worse case it blows a seal somewhere.

"worst" case is it contaminates your boost control solenoid, allowing over-boost and blowing engine!!!

do not drive hard and get it drained asap.................

that happened to me and it blew the front oil crank seal
cost me £300 to fix it

:(

Would have to contaimnate the pressure sensor too for it to stop the fuel cut kicking in...but...it can happen ;)
