I've made that statement the last two years after watching the trend over prior years. This year has been different, and perhaps the commodity demands are changing, affecting prices. In April we bought for $3.34/gal. A few weeks later the price was closer to $4/gal. We bought again last week and it cost $3.24/gal. Better, for certain, but still not even close to the $2.34/gal we paid all of last year (the price was stable too).
Methanol is typicall made from natural gas. Since natural gas is used for heating in the winter, demand is higher, and subsequently, less methanol is produced. The laws of supply and demand ensure that the prices of methanol thusly increase in colder months. (HINT: stock up in Autumn if you process through the winter)
