And of course, it did not help that the EPA-Congress-Politicians loaded up mogas with ethanol for the " farm lobby " that only proved harmful to many internal combustion engines.
- It damages the integrity of plastic and rubber in small engines, leading to parts failure, higher running temperatures, and poor reliability.
- Other issues include phase separation, vapor lock, corrosion, oxidation, and alterations to combustion and compression ratios.
- Ethanol can cause increased wear on the engine.
- Using a higher blend than recommended can lead to serious problems.
- Ethanol corrodes many components used in internal-combustion engines and their fuel systems.
