Will keep a look out for cheap oil - the last lot was from Asda, about £5 for 5 ltrs of semi synth 5/30 and try and change as frequently as possible. And as I said before I'll run some more BC109 through it before I drop the oil every other change.
I have just added last night a HIH (hose in hose) heat exchanger. Not running my fuel line through it yet, but once I know it's not leaking coolant anywhere and it's getting warm, I will do. Not the most effective Heat Exhanger but simple, cheap and puts the IP under least strain lifting the fuel from the tank. Obviously it will take a while for this to heat the oil up as it relies on coolant.
Think I have all the bits I need for Water Injection now, just testing it off the car first - once I'm happy then I will install it and see how it goes. Here's the thread on the Veg forum about it. They were injecting pre-turbo to start with (just to test it's afectiveness) which isn't a long-term option as it will wear the turbo quickly.
