What will happen if I accidentally put E85 instead of 87? If you accidentally put E85 instead of 87 octane gasoline can lead to reduced engine performance, lower fuel efficiency, potential damage to the fuel system, and increased emissions. It can damage the engine severely.
Here I will tell you the consequences and what should you do after doing so.
I Accidentally Put E85 Instead Of 87 – Is E85 The Same As E87?
If you accidentally use E85 instead of the recommended 87-octane gasoline, several issues may arise. E85 contains a higher ethanol content compared to regular gasoline (like 87 octane). Using E85 in an engine designed for 87-octane gasoline can lead to reduced engine performance, decreased fuel efficiency, potential damage to the fuel system, and increased emissions.
Additionally, E85 and E87 (87 octane gasoline) are not the same. E85 contains significantly more ethanol and less gasoline compared to E87. It makes them distinct fuel blends with different properties and impacts on vehicle performance.
Difference Between E85 And E87: E85 vs E87
Let’s see the comparison between E85 and E87.
| Aspect | E85 | E87 |
|---|---|---|
| Ethanol Content | 51% to 83% ethanol, 17% to 49% gasoline | Negligible ethanol content, mostly gasoline with up to 10% ethanol |
| Octane Rating | 100 to 105 | 87 |
| Performance | Higher octane, better performance in Flex Fuel vehicles | Standard performance for most vehicles |
| Fuel Efficiency | Lower due to lower energy content per gallon | Better fuel efficiency due to higher energy content |
| Environmental Impact | Reduces greenhouse gas emissions when used in designated vehicles | Relatively smaller impact on emissions |
| Availability/Compatibility | Less available, requires Flex Fuel vehicles | Widely available, compatible with standard gasoline vehicles |
| Cold Weather Performance | Challenges in cold climates, potential starting issues | Performs well in various weather conditions |
| Price | Often cheaper due to subsidies promoting ethanol use | Typically priced as standard gasoline |
| Engine Compatibility | Requires Flex Fuel vehicles designed for higher ethanol concentrations | Compatible with most standard gasoline engines |
What Are The Consequences If I Accidentally Put E85 Instead Of 87? 4 Aftereffects
Accidentally using E85 instead of 87-octane gasoline can lead to several potential consequences:
1. Reduced Engine Performance
E85 has a higher ethanol content and lower energy content compared to regular gasoline (87 octane). Using E85 in an engine designed for 87-octane gasoline can result in reduced engine performance. This may include decreased power output, lower fuel efficiency, and potential engine knocking or misfiring.
2. Fuel System Issues
E85’s higher ethanol content can affect components in the fuel system not designed for such concentrations. Over time, this can lead to damage, corrosion, or deterioration of fuel system parts, including seals, hoses, fuel lines, and injectors.
3. Emissions Impact
E85, when used in a non-Flex Fuel vehicle, might cause an increase in emissions due to incomplete combustion compared to regular gasoline. This can lead to higher levels of pollutants being released into the environment.
4. Warranty Concerns
Using an incorrect fuel type can potentially void the vehicle’s warranty if it results in damage to the engine or fuel system.
What Should I Do If I Accidentally Put E85 Instead Of 87?
If you accidentally used E85 instead of the recommended 87-octane gasoline, it’s essential to address the situation promptly:
Dilution
Try to dilute the E85 with regular gasoline by filling up the tank with the correct fuel, 87 octane gasoline, as soon as possible. This will help lower the overall ethanol content in the tank.
Avoidance of Heavy Usage
Avoid heavy usage or driving long distances if feasible until you’ve diluted the E85 with regular gasoline. This minimizes potential adverse effects on engine performance.
Observation
Pay attention to any changes in your vehicle’s performance, such as rough idling, reduced power, or engine knocking. If you notice any unusual symptoms, consider seeking a mechanic’s evaluation.
Monitoring
After refilling the tank with the correct gasoline, monitor your vehicle’s performance over the next few driving cycles. If you notice persistent issues, it might be wise to have the fuel system inspected by a professional.

Bottom Line
Accidentally using E85 instead of 87 octane gasoline can severely impact your vehicle. It may cause reduced engine performance, lower fuel efficiency, potential damage to the fuel system, increased emissions, and even void warranties due to engine damage.
E85, with its higher ethanol content, isn’t suitable for engines designed for 87 octane gasoline. Diluting the fuel by refilling with the correct gasoline promptly is important. Monitor your vehicle for changes in performance and seek a mechanic’s evaluation if issues persist. Acting swiftly can mitigate potential damage and maintain your vehicle’s optimal functioning.
