cheers for the replies all
On the flip side, 'What if' if the garage that serviced the car, what if they only filled the car with 5 1/2ltrs of oil instead of the 7 1/2th ?
Am guessing the car would run fine, it would just be running with a lower oil amount maybe ?
I ordered a mahole filter last night + 8ltrs of Castrol edge LL04 5w30 .....
Piece of mind says to get an oil change done again, and mention to the guy i will use some of the notes in this thread...
I'll dig this thread out when i get the work done and write up if any faults found, etc etc..
I used to change oil in my Nissan's every 6k miles, so if turns out on a mapped 335d that oil changes are quite often, i can live with that, i love this car, so want it to last!
