Can't buy clear gas in the Denver Metro Area anymore (year round) because of the subsidies even though stations are only required to carry it four months out of the year. Last station stopped selling it a year ago because the owner couldn't compete. E10 is cheaper — guess why.
What they've done is actionable on many levels(i.e. stealing our money to help corn whores, ruining our machinery with crappy product, etc.).
In the meantime, try additives, anything you can get your hand on, experiment.
I try to supplement every tankful & have found it very useful.
The Lucas product are good albeit pricey, so I'm more inclined to experiment with Big Lot's product, etc..
