Methanol, methyl alcohol or wood spirits, the last being a very old name.
In Aus methylated spirits is ethanol with a small amount of methanol added to stop (most) people drinking it.
The page you've linked to seems to be methanol for racing cars - I know racing cars use methanol, it might be OK but there's no details, it'd be as well to ask them to make sure they don't add small amounts of lubricants or other stuff to keep the engines happy.
If it is pure it'd be a good source, since the quantities used by cars tends to keep the price per litre down.
