Price is down to $1.69 a gallon but it is going up again as people get back to work. If you are thinking of filling a bunch of gas cans be sure to add Sta-Bil to the gas to keep it from going bad in more than a few months time. Even then it is stabilized only for six months at best (less the higher the temp out side gets).
i usually put in $10-$20 at a time depending on how much I will be driving it the next couple weeks. If I know it is going to be sitting a couple weeks, usually just do a small amount. Easier for me to cycle new gas instead of full tank to full tank and going a month or so between fill ups.
