From what i know the quantity of oil should be 6ltrs, when they drained it it have a little over 9ltrs, that was just from opening the pan, oile was also there in my exhaust all the way from headers till the catback.
I hade to have it all chemically washed.
And what was really confusing is that untill i took it for repair there was no codes, no check engine, nothing!!!
This is all based on the repair report that i was givin and talking to the mechanic.
