Updating old auto engines
Ethanol is highly corrosive and damages older fuel system components not made to resist this corrosion.
If you have anything to be concerned about with older and classic vehicles, it is this problem.
The problems I saw most often were damage caused by ethanol in gasoline.Unfortunately, running vintage cars on contemporary gasoline containing ethanol can create problems for classic car owners.Most of these cars run best on pure gasoline, not gasoline treated with ethanol.Thanks to regulations from the federal government and the economics of the farming and fuel industries, finding pure 100 percent gasoline is nearly impossible.
Lots of documentation exists about damage to all kinds of engines running on E10 gas.Now, you can help to blunt this concern by treating the fuel.
