At Zombie Auto Works, we’ve seen it all when it comes to fuel mix-ups. One of the most common (and frustrating) mistakes vehicle owners make is accidentally filling their gasoline engine with diesel fuel. If this happens, don’t panic—our team specializes in fuel system decontamination and can get your vehicle running smoothly again.

Why Is Diesel in a Gas Engine a Big Problem?

Gasoline and diesel fuel are completely different in terms of combustion properties and engine requirements. Here’s why filling up a gas-powered car with diesel can be disastrous:

    •    Diesel is thicker and oilier than gasoline, making it difficult to ignite in a gas engine.

    •    Gas engines rely on spark plugs to ignite fuel, but diesel requires compression ignition, meaning your engine won’t run properly—or at all.

    •    Diesel clogs the fuel injectors, fuel pump, and lines, leading to costly repairs if not addressed quickly.

    •    Residual diesel leaves behind carbon deposits that can cause long-term engine damage.

Signs Your Gas Engine Has Been Contaminated with Diesel

If you’ve accidentally put diesel in your gas tank, you’ll likely notice these symptoms:

✔️ Hard or no start – Your engine may struggle to turn over or fail to start completely.

✔️ Thick, white smoke from the exhaust – This is a telltale sign of improper combustion.

✔️ Rough idling and misfires – Diesel doesn’t burn as efficiently in a gas engine.

✔️ Check engine light – Your vehicle’s ECU will detect abnormal combustion patterns.

✔️ Strong diesel smell – If you notice a heavy diesel odor after refueling, stop driving immediately.
