When used with a properly installed eFlexFuel E85 kit there is no risk for engine or component damage.
However, E85 offers several proven advantages for engine performance and operation.
High octane fuel
E85 is high octane fuel without the Premium price — typically 100–106 RON, depending on the country.
This can result in:
- Increased potential power and torque
- Greater resistance to engine knocking, making knocking issues far less common
Cooler combustion
E85 burns at a lower combustion temperature than gasoline, which can:
- Reduce thermal stress on engine components
- Be beneficial for engines operating under higher loads or boost
Cleaner combustion
E85 burns cleaner than gasoline and has natural cleaning properties.
This helps:
- Reduce carbon buildup in the engine
- Keep injectors and intake components cleaner over time
Affordable price
- E85 is usually more affordable than gasoline. Depending on the country.
Engine safety with eFlexFuel
E85 does not damage the engine when an eFlexFuel E85 kit is correctly installed and vehicle compatibility is properly verified through our compatibility checker or support team.
The eFlexFuel system ensures:
- Correct fueling at all ethanol levels
- Reliable cold starts
- Safe air‑fuel ratios always
Addressing common misconceptions
There are still many online rumors claiming that E85 is corrosive to vehicle components. In reality, automotive manufacturers have been using ethanol‑compatible fuel system components since the late 1980s. Normal gasoline already contains 5-10% ethanol (E5, E10).
Modern gasoline vehicles — when properly equipped with an eFlexFuel kit — are designed to safely handle ethanol‑blended fuels without causing damage to engine or fuel system components.
