I have a quick question about ether.

I just priced a purchase from a chemical supply mob (around AUD$90 - $100 for 2.5 litres + $30 for shipping). They have various grades of ether available.

Is it necessary to buy one of the anhydrous grades of ether, or is it a case that its all the same stuff and the anhydrous grade is just tested as being water free? Ie. if I don't buy the anhydrous ether am I in danger of getting water in my fuel?

Depending on whether it needs to be anhydrous or not, I'll be getting either :-

Product code: EA012/2.5L Diethyl ether AR
or Product Code: EA036/2.5L Diethyl ether anhydrous AR

It'll work out to around AUD$17.50 per litre of 45%/30%/25% Diesel/Ether/Castor fuel.

thanks,
Col
