Using improper or low-quality fuel can lead to a range of problems that can cause costly repairs down the line. While saving a few cents at the pump might seem appealing, the long-term effects on your engine can be severe.
Clogged Fuel Injectors
Low-quality fuel often lacks the necessary detergents to keep the fuel system clean. Over time, carbon deposits build up on the fuel injectors, disrupting the precise spray pattern needed for efficient combustion. This leads to rough idling, hesitation, and poor fuel economy.
Engine Knock and Damage
Using fuel with a lower octane rating than your vehicle requires can cause engine knock (pre-ignition or detonation). This occurs when the fuel-air mixture ignites prematurely. Severe engine knock can cause catastrophic damage to pistons, valves, and spark plugs.
Always use the fuel grade recommended in your owner's manual. If you suspect fuel system issues, the technicians at Metro Transmission & Auto Repair can perform a professional fuel system cleaning to restore performance.
