zx1 for the xk
i mate,zx1 is a friction eliminator,its not a oil additive as such,but please do look it up on line its very interesting.it can also be used in the fuel and water to help the pump,it clings to all moveing parts to stop friction and wer.
oh, and 'engine restore' on the 4.0 engines that have lost some compression. Its the only two aftermarket products i've observed jaguar techs and other knowledgeable mechanics recommend in our vehicles.
