koan: I sought your e-mail address in your profile, but it was hidden from me.

I tried PMing you, and the forum's mailserver failed (according to the message I received).

Perhaps e-mail me (ozbenzhead@internode.on.net) to establish the connection, then I can reply with documents.

Cheers

Ok... probably a stupid question - but do i have to put lead substitue in??
I put it in every fill of petrol, mainly out of habit cause of the dato...
I've also used that lead substitue & octane boost, which says don't use if you have a catalytic converter - though being the euro spec i don't think i do?!

Main question:  Should i always use Lead substitute or does it not require it?
I always fill up with the premium 98 fuel whichever servo i'm at - should i be getting the ol' girl tuned especially for this and if so - who can tune it properly??

Always 98 RON.  In an emergency - e.g. needing fuel when there's no 98 available - 95 will do, although the engine might ping, or otherwise underperform a little.

No additives required.

Yes - find someone to tune it for 98.

A note on 98 RON fuel varieties:
I always, whenever possible - so in my home town no problem - use Caltex Vortex 98 (beware - ordinary Vortex is 95).  When I can't get Cal-Vortex, I go for BP.  I always try to avoid Shell Optimax, as three times I've had a tankful of it from a bad batch; Shell has admitted to having the occasional "problem" at its refineries, resulting in a "dirty" mix.
