Diesel in a Petrol Car vs Petrol in a Diesel: What to Do

<p>Putting the wrong fuel in your car is easier to do than most people think, and it happens at forecourts across United States every day. The two common mistakes are diesel in a petrol car and petrol in a diesel car. Both need attention, but they are not equal. One is usually a nuisance; the other can be genuinely destructive. Understanding the difference helps you act quickly and avoid turning a simple mistake into an expensive repair.</p> <p>Diesel in a petrol car is the less serious of the two, mainly because of how the two fuels behave. Diesel is heavier and oilier than petrol, and a petrol engine simply cannot run on it. In most cases the engine will splutter, misfire, or refuse to start shortly after the diesel reaches the fuel system. The good news is that petrol engines are generally more forgiving: because diesel does not ignite the way petrol does, the engine often stalls before major damage occurs. The key is not to keep trying to start it. The more you crank the engine, the further the diesel is pushed through the system.</p> <p>Petrol in a diesel car is a different story, and it is the one that causes the most expensive damage. Diesel engines rely on diesel fuel to lubricate the high-pressure fuel pump and injectors. Petrol acts as a solvent rather than a lubricant, stripping away that protection and causing metal-on-metal wear almost immediately. Even a short drive can damage the fuel pump and injectors, and the repair bill for those components can be substantial. This is why petrol in a diesel is widely considered the more dangerous misfuel.</p> <h2>What to do right now</h2> <p>Whatever you have put in, the number one rule is the same: do not start the engine. If the engine is already running, switch it off as soon as it is safe to do so. Do not try to drive the vehicle, even a short distance, and do not attempt to siphon or drain the tank yourself. Modern fuel systems are sealed and complex, and DIY attempts can cause further damage or create a safety risk.</p> <p>Move yourself and any passengers to a safe spot, then call <a href="tel:18667773712">(866) 777-3712</a>.
