You've been busy, but saw this

... A friend advised adding a small amount of Castor oil to the water/ meth mix is helpful in controlling the corrosion that can result from those liquids on metal surfaces

That'll smell nice, but won't it have a negative effect on your wideband sensor?

Intesting point, what else can affect the sensors? As an example, an engine that burns a slight amount of oil, etc. My left cylinder seems to allow about 1500 mile/liter oil consumption since I have had bike, but I haven't noted problems with the sensor. I do a recal about once a season.
I believe he used the Castor oil, as he also was working with 100% meth (1 tablespoon per gallon). Had a small Audi fuel pump flowing the meth & didn't seem to fail for him (perhaps the Castor oil)
That's not my plan, as my understanding is that a 50/50 mix will do the job just fine. As well, reservoir will be coated, SS fittings and such.
I think I'll leave the Castor oil out
