I've noticed that quite a few people have been asking this same question.
Is there an issue here with Tax avoidance? i.e. are plod going to take a dim view of this.
I imagine it's the same question around using chip fat in a diesel, did they not have to legislate to allow it?

Hi Harry
upgrade your fuel lines injecter rings speak to your mapper and go for it, who knows might be some gains proberly not as significant as 20% but give it a try and let us know how you get on.
is it still on a standard motor?

Have played with a few combinations and percentages.
Beyond 20% there is little gain if you treat it like petrol with an additive, at 50% I found you have to treat it like tuning meth just not as good meth as it is watered down in effect.
So all tuning needs rethinking and done looking at the basics from a different angle and using egt to find afr target rather than just going with normal petrol / meth mix.
I have seen no down sides but not run more than 20% meth longterm enough to be sure.

you may pay vat on the meth your buying, the same way you pay vat on parrafin or rebated diesel (red diesel) vat isnt the issue its road fuel duty that your avoiding and if you get caught be prepared for heavy conscquences and that will include you car being seized, Its just as illegal as using red diesel....
try buying fuel grade methanol from a fuel supplier and youll get a shock that £125 for a 45 gallon drum of "cleaning fluid" becomes £500+ for the same stuff when its sold as motor fuel
also the air fuel ratio of pure meth is way more than normal petrol, l you can burn almost 2.5 times more methonal for the same amount of air ,
20% probably dont change your mpg much, pure meth will dramaticaly change your mpg so the bennefit of being cheaper if you take a chance and use cleaning fluid is non existant
af ratio for petrol is 14:1
af ratio for methanol is 6:1

Rough costs would be £600 for the kit + £200 for a suitable water tank i.e. Spec C boot tank and then 6+hours for fitting + re-map.
Normal application is to run 50/50 water/meth but I hear some run up to 20/80% for more power.
