I don’t want to contradict or anything here but some of the older ideas in the above posts no longer hold true.
Most oil companies now add a percentage of ethanol (corn/sugar alcohol) to their gasoline.
Anything below 15% ethanol will not be noticeable in the running of a vehicle; above that percentage will or could cause running issues. Harder starts, loss in fuel mileage & power.
That’s where the E85 compatible vehicles come into play, 85% alcohol 15% gas; along with electronics that compensate for the variable differences in the fuel.
Ok with that being said Ethanol has a natural positive magnetic charge, where gasoline has a neutral charge. The neutral charge of gas will allow particles (dirt) to settle and accumulate on the bottom of the tanks.
The positive charge of ethanol keeps these particles suspended (floating); so when dirt is introduced to the large tanks, it doesn’t settle, it gets pumped out, with everyone getting a bit of this dirt.
Plus alcohol disperses water, the same as what methyl hydrate (gas line anti freeze) does; so unless there’s a whack of water introduced to a tank, condensation is no longer an issue.
15 or so years ago, when I still had my gas station; the company notified us that they were beginning to add ethanol and that the maintenance department would be out to remove the filters from the gas pumps.
They knew there was sediment in the bottom of their tanks and it was going to plug up their pump’s filters.
After about 6 months of fuel with ethanol being put through the tanks; maintenance came back and reinstalled the filters. They knew the tank would be flushed out by then.
If we had a customer complaint of a plugged fuel filter in their vehicle; we were to replace the filter and the company would reimburse us for the cost.
Right or wrong but their philosophy was, if we don’t tell anyone during the change over they wont know. Once the transition was complete they advertised that their fuel was environmentally friendly because of the ethanol being a renewable resource.
Economicly ethanol hasn’t done anything for us; we haven’t seen a decrease in the cost of fuel but an increase in the cost of beef & pork.
The farmers now have to compete with the oil companies when purchasing corn to feed their livestock.
I know I’ve gone way off subject but I’m so tired of the propaganda these large companies force apon us; I get upset and start to ramble. LOL
