Here's a breakdown of potential consequences:
* Gasoline in a Diesel Engine: This is generally more damaging. Gasoline burns much faster and hotter than diesel, and diesel engines aren't designed to handle this. You could experience:
* Engine damage: The fuel injectors and pump might be damaged due to the different viscosity and chemical properties. The high combustion temperature can melt or warp components.
* Fuel system contamination: The gasoline can strip lubricating properties from the fuel system, leading to premature wear and tear.
* Immediate engine failure: In some cases, the engine might seize up or stop running completely.
* Diesel in a Gasoline Engine: This is less immediately catastrophic than gasoline in a diesel, but it can still cause serious problems.
* Engine misfire/rough running: The diesel fuel doesn't burn properly in a gasoline engine, resulting in poor performance and misfires.
* Fuel system blockage: Diesel fuel is thicker and can clog fuel injectors and filters.
* Damage to fuel injectors: The injectors could be damaged from trying to atomize the thicker diesel fuel.
* Possible catalytic converter damage: Unburnt diesel fuel can damage the catalytic converter.
What to do if you put the wrong fuel in your Cadillac:
1. STOP IMMEDIATELY: Do not attempt to start the engine if you realize you've put in the wrong fuel.
2. Do not turn the ignition key: Turning the ignition will cause the fuel pump to send contaminated fuel through the fuel system increasing the damage.
3. Call a roadside assistance service or tow truck: Get your Cadillac towed to a qualified mechanic or dealership. Do not attempt to drive it.
4. Inform the service professional: Clearly explain what happened and what type of fuel you mistakenly used.
The best course of action is prevention. Always double-check the fuel nozzle and fuel filler before you start pumping. If you're unsure, ask for assistance at the gas station. The cost of repair from using the wrong fuel will likely far exceed any savings from a less expensive fuel option.
