Hi Jeepy, I have the same car as you......
TYRES- for me there is a balance between comfort and handling . I would suggest a MINIMUM of 22psi (and check regularly as on Morgans they do deflate over time), but find handling improves when inflated to 26psi, but you do feel the bumps! Try within that range for what suits you, also taking into account tyre condition and type of roads on which you do most of your driving.
OIL- just had mine serviced at the factory and they used Synth 5W-40 in my duratec 2L.
