Unfortunately there is no pure gas available within 100 miles of St Louis (that I've found).

As far as fuel problems, fuel lines, primer bulbs, diaphragms. Only in the handhelds. I have several old Toro T-bar walk behinds, one a 1998, one a 1994. Both with Kohler command engines. No fuel problems from them ever. Both have a zillion hours on them.

I've heard (no proof) that the ethanol blend is not very precise. One batch of E-10 may be 5% ethanol, another batch may be nearly 20%. Purely heresay, but it does explain the occasional meltdown of plastic/rubber.

I understand the EPA is in the roadtest phase with E-15... Won't that be lovely? More ethanol. Probably find the point it kills 4-cycle stuff soon.

The question I would like answered: does it make sense from an enviromental perspective to switch to these more "environmentally friendly" standards and fuels? How "green" is it to have to replace the equipment every couple years (or less). And how much fuel gets "dumped" due to concerns of age or moisture? Or due to DIY service to combat rotted fuel lines etc? I suspect in typical fashion, the new Government standards and fuels have made matters worse rather than better.

I have absolutely no SCIENTIFIC proof, just some real world testing.

A couple years ago, me and my uncle were curious to see if the advertising claims of companies like Shell, were true...that they actually do help clean the fuel system and improve your mileage. While we didn't actually tear down an engine to see how well the fuel "cleaned", we did test the fuel economy improvements.

At the time I was driving a diesel truck, so I couldn't use my truck for the testing. We used my uncle's 1997-ish Honda accord 4 cylinder. For work he would travel several hundred miles a week (puts about 20,000+ miles on a vehicle each year). For years he had just been using fuel from multiple different stations as he needed fuel. He is very good at keeping track of how much fuel he uses, the miles he gets out of each tank, etc. So we had number to work off of from the start.

Like I said, he originally would go to just about any station as he needed gas...the old admiral station by his house, a marathon station off the highway, whatever. So after deciding to see if the claims by SHELL were true, he only filled up with shell fuel, same REGULAR gas that he always bought (never did the mid grade or higher fuels). After a couple tanks of Shell gasoline, he was getting a constant 30 miles more on a tank of gas from shell over gas from various stations. He was driving the same roads before and after switching to shell, there was no difference in the roads he took before or after.
