Defender Td5 - which engine oil
somebody i know from a german landrover forum is touring thru the us w/ his defender td5 my 2003 right now. he has to do an oil change but is not sure which oil to use. as european and us specs are a little different, is there an oil you can recommend? he is using a Castrol 5W40 A/B3 right now. can he get this oil somewhere in the us (not sure where exactly he is at the moment) or is there something similar?
i'm in europe at the moment so i'm not a great help for him. would be super if you guys could recommend something.
