I really don't like those new ventless gas cans. Why did we have to change? Did the EPA or some govt agency have their nose where it didn't belong? First of all, they don't pour good - especially the 5 gallon cans. It takes twice as long as it used to to fill up the mower. Also, the gas always sloshes out of these things. The little yellow caps are useless and always get lost and so when I hit a bump, there goes a little bit. I think that a bunch is evaporating as well. I think that I loose about 2 gallons per week with these things. That is not a lot but I could use that extra $6 for something better. If the change was just a decision by Blitz, it was a terrible one.
