    The oil that VX reccomend is 5W30 fully synthetic, so as long as it meets that spec you should be fine..

    Remaps are possible.. torquingBHP in cambridge have a very good reputation having mapped beautifully two members cars in the past..

    Timing belt change is scheduled at 80,000 miles..unless you are 100% on that engine and want to buy the locking tools, give it to the dealer to do..too much can go wrong.

    Big issues with remaps of the 3.0CDTi....the engine, although indestructible when standard, doesn't seem to cope with extra power very well. Maverick has been working with the VXR Performance Centre to try and get a remap written, but no joy yet. Hang on - is yours a facelift or pre facelift?

    Definitely do it. It should have been done at 40k, although Vx 'recommend' 80k - might be worth checking the service history to make sure it wasn't. If not, get it done sooner rather than later.
