Diesel vs. Petrol
* Fuel Type: Diesel and petrol are very different fuels. Diesel is denser and has a higher flash point than petrol.
* Combustion: Diesel engines use compression ignition, while petrol engines use spark ignition. This means diesel needs to be compressed to ignite, while petrol needs a spark.
What Happens When You Mix Diesel and Petrol
* Fuel System Damage: The diesel will not combust properly in a petrol engine. This can lead to clogging of fuel lines, injectors, and the fuel pump.
* Engine Problems: The mixture will not ignite effectively, causing the engine to misfire, stall, or run poorly.
* Damage to the Catalytic Converter: Diesel fuel can damage the catalytic converter, which is designed to reduce harmful emissions.
* Costly Repairs: Fixing the damage caused by mixing diesel and petrol can be expensive, potentially requiring significant repairs or even a complete engine replacement.
What to Do if You Accidentally Put Diesel in Your Petrol Car
1. Stop Driving Immediately: Do not try to start the engine if you realize you've added diesel.
2. Contact a Mechanic: Call a qualified mechanic and explain the situation. They will be able to advise on the best course of action.
3. Drain the Fuel Tank: The mechanic will likely recommend draining the fuel tank and replacing it with fresh petrol.
Prevention
* Be Careful at the Pump: Always double-check the fuel nozzle and label before filling your car.
* Keep Your Receipts: Receipts can help identify the type of fuel you purchased if you have any doubt.
Key Takeaway: Even a small amount of diesel in a petrol car can cause significant damage. If you accidentally mix the fuels, stop driving immediately and contact a mechanic for professional assistance.
