Understanding Bad Gas
Bad gas refers to fuel that has deteriorated over time, becoming contaminated or oxidized. This can occur due to several factors:
Age: Gas starts to degrade after a few months, especially when exposed to heat or sunlight. Contamination: Water, dirt, or debris can contaminate the fuel tank, affecting the quality of the gas. Ethanol Content: Ethanol, a common additive in gasoline, attracts moisture and can cause phase separation, leading to bad gas.
These factors can lead to problems with your engine, including:
- Fuel System Blockages: Deposits from bad gas can clog fuel lines and injectors, hindering fuel delivery.
- Corrosion: The corrosive nature of bad gas can damage metal components within the fuel system.
- Incomplete Combustion: Bad gas burns inefficiently, leading to reduced power and poor fuel economy.
Dealing with Bad Gas
Here's how to address the issue:
- Avoid Bad Gas: Store gasoline in approved containers, away from heat and sunlight. Use gas within a reasonable timeframe.
- Use a Fuel System Cleaner: Adding a fuel system cleaner to your tank can help to break down deposits and improve fuel flow.
- Fuel Filter Replacement: A clogged fuel filter can worsen the effects of bad gas. Replacing it can help restore fuel efficiency.
- Professional Inspection: If symptoms persist, have your car inspected by a mechanic to rule out other potential problems.
