They filled my oil up to the max and asked me to drive 1000miles to begin with and go back so they can check where it was on the dipstick, but mine was all gone. So then they said they stripped all the oil out, weighed what was going back in, done 60 miles then weighed it again to see how much it had used. Then after that god knows what they done.
I'd imagine it might have fixed it, depends on how much damage was done before it was fitted?
