An assistant ask could he help me, and I told what I was after.
He ask what engine I had in the RR and not being sure ( I wouldn’t have a clue ) he then suggested he could get the correct info.
He asked for my rego number and pumped it into the computer and he had all the info needed for the correct oil.
As above this might help you.
