Here's why:
* Engine knock: The 2.0T engine is designed for higher octane fuel (91 or higher). Lower octane fuel can lead to engine knock or pinging, which is a damaging detonation that can occur when the fuel ignites prematurely.
* Reduced performance: The engine will likely experience a reduction in power and torque, making the car feel less responsive and less fun to drive.
* Increased emissions: The engine's efficiency will decrease, resulting in higher emissions.
* Potential for damage: While occasional use of lower octane fuel might not cause immediate damage, consistently using 87 octane could eventually lead to engine wear and tear.
It's crucial to use the recommended fuel for your vehicle. The fuel cap or owner's manual will clearly state the minimum octane rating required. Using the specified fuel ensures optimal performance, longevity, and emissions for your engine.
Instead of using 87 octane, consider these options:
* Use the recommended 91 octane fuel: This will ensure optimal performance and engine health.
* If you find yourself in a pinch and have no other option: Using 87 octane for a short distance might be okay, but avoid it as a regular practice.
It's always best to err on the side of caution and use the fuel specified by your vehicle's manufacturer.
