The Ford Mustang is an iconic muscle car that has captured the hearts of enthusiasts worldwide. In this article, we’ll delve into the possibility of running E85 fuel in a 2018 Mustang GT and explore its pros and cons. can a 2018 mustang gt run e85

Introduction

The Ford Mustang GT, with its powerful V8 engine, is a force to be reckoned with on the road. But what if you wanted to take your performance even further by switching to E85 fuel? E85, a blend of 85% ethanol and 15% gasoline, has gained popularity among enthusiasts for its environmental benefits and increased octane rating. In this article, we’ll examine whether a 2018 Mustang GT can run on E85 and what you might expect in terms of performance.

Answer to the Question

In short, yes, a 2018 Mustang GT can technically run on E85 fuel. The engine management system (EMS) is capable of adjusting fuel injection parameters based on the type of fuel being used, so it’s not a matter of if but rather how well it will perform. However, there are some caveats to consider.

Fuel System Compatibility

The primary concern is ensuring that your Mustang GT’s fuel system can handle the higher ethanol content in E85. The stock fuel lines and hoses might be incompatible with the more corrosive nature of E85, potentially leading to premature degradation or failure. To mitigate this risk, you’ll need to upgrade your fuel system with components specifically designed for E85 use.

Engine Modifications

Another consideration is the engine itself. While the 5.0L V8 engine in the Mustang GT can run on E85, it may not be optimized for the higher-octane fuel. You might experience reduced power output or even engine knock (pinging) due to the increased ethanol content. To address this issue, you could consider installing an engine calibration tune specifically designed for E85 use.

Drivetrain and Transmission

The drivetrain and transmission in your Mustang GT are also worth considering when switching to E85. The higher viscosity of E85 might affect lubrication and wear on the transmission components, potentially leading to premature failure. You may need to upgrade your transmission fluid and consider installing a transmission-specific tune.

Pros and Cons

Now that we’ve covered the technical aspects, let’s weigh the pros and cons of running E85 in your 2018 Mustang GT:

Pros

  • Environmental benefits: Running on E85 reduces greenhouse gas emissions by up to 26% compared to traditional gasoline.
  • Increased octane rating: E85 has a higher octane rating than regular gasoline, which can help reduce engine knock and pinging.
  • Potential power gains: Depending on the calibration tune used, you might experience increased power output due to the higher-octane fuel.

Cons

  • Fuel system upgrades: You’ll need to invest in upgraded fuel lines, hoses, and possibly injectors to ensure compatibility with E85.
  • Engine modifications: The engine may require a calibration tune specifically designed for E85 use to optimize performance.
  • Higher costs: E85 typically costs more than regular gasoline, potentially offsetting any environmental benefits.
  • Limited availability: E85 is not widely available and might be harder to find in your area.

Conclusion

While it’s technically possible to run E85 in a 2018 Mustang GT, you’ll need to consider the potential modifications required to ensure compatibility and optimal performance. Weighing the pros and cons carefully will help you make an informed decision about whether switching to E85 is right for your ride. Remember to consult with a professional mechanic or a reputable tuning company before making any changes to ensure the best possible outcome.
