Although not for a Land Rover could someone with technical knowledge help me please?
My other car is a Renault Laguna turbo diesel 2.2 2003. The man in the service dept at my local Renault dealership said that the oil to use is 5W30 fully synthetic. I duly filled with this on my last service but have since noticed in the service manual it says to use
5W40. Does it matter that much, should I change to 5W40 immediately or wait till the next service?Also, does synthetic/semi count for much?
Thanks, Tony
P.S. I wish my td300 could produce the torque the smaller Renault engine produces!
