It seems to me that the oil companies are pretty much in bed with all governments, and if the governments go to the oil companies and say "look, we need help to keep the economies going... lighten up on the cost a bit so we can keep people driving, and in turn consuming other goods and services. Go ahead and jack it back up once this settles down a bit."
Just an opinion. Can't back it up with any info...
But, it's nice that it's only costing me $25 to fill up again! One guy at work actually asked me if I was kicking myself now that prices were dropping... (he's socially clueless, and a bit of a jerk). but I just smiled and said "no, I'm ok that it's costing me less than $25 to fill up again. Unlike when it cost me $50 to fill up my Maxima to go the same distance." (He drives a Maxima, too).
