What happens if I put the wrong gas in my Lexus?
Putting the wrong type of gasoline in your Lexus can have serious consequences for your vehicle. Using the incorrect fuel can damage your engine and fuel system, leading to costly repairs. It's crucial to always refer to your owner's manual and use the recommended fuel grade for your Lexus model.
Potential Consequences of Using the Wrong Fuel
Filling your Lexus with the wrong gas can result in several problems:
- Engine Damage: Using a lower-octane fuel than recommended can cause engine knocking or pinging, which can lead to serious engine damage over time. Higher-octane fuel is designed to withstand higher compression without detonating prematurely.
- Fuel System Damage: Incompatible fuels can corrode or clog fuel system components like fuel injectors, fuel pumps, and the catalytic converter.
- Decreased Performance: Using the wrong fuel may result in reduced engine power, acceleration, and fuel efficiency.
- Emissions Issues: Incorrect fuel can cause your vehicle to emit higher levels of pollutants, which may trigger check engine lights and fail emissions tests.
The severity of the consequences depends on factors like how much of the wrong fuel was added and how long it was driven in that condition.
What to Do If You Put the Wrong Fuel in Your Lexus
If you realize you've put the wrong fuel in your Lexus, it's important to take immediate action:
- Don't Start the Engine: Avoid starting the engine, as this can circulate the incorrect fuel through the system and cause more damage.
- Call for Roadside Assistance: Contact your Lexus dealer or a towing service to have your vehicle safely transported to a repair shop.
- Drain the Fuel Tank: The incorrect fuel will need to be drained from the tank and fuel system before refilling with the proper fuel.
- Inspect the Fuel System: A mechanic should inspect the fuel system for any damage and make necessary repairs before refueling.
Catching the mistake early and taking the right steps can help minimize the potential for long-term damage to your Lexus.
Preventing Fuel Mix-ups in the Future
To avoid putting the wrong fuel in your Lexus, always double-check the fuel type recommended in your owner's manual and the fuel tank label. Additionally, be mindful of the fuel pump nozzle size, as diesel nozzles are typically larger than gasoline nozzles, making it difficult to accidentally fill a gasoline-powered vehicle with diesel.
