Nice one gents, thanks for the info. I've got a local supplier in Lincoln who charges £17.50 for 25L of Methanol and £12.50 for 25L of De-Ionized water.
I've got it setup on racking I'm my garage with taps on the 25L dispensers so filling and mixing is really easy.
I've also got the AEM Kit with dual port injection and I've been getting through it pretty rapidly too!
