Petrol in Diesel Car: Damage, Timeline & Repair Process

When petrol is mistakenly added to a diesel engine, it creates a chemical imbalance that can rapidly degrade vehicle performance. Petrol's lower viscosity compared to diesel leads to poor combustion, causing engine knocking and carbon buildup. Modern diesel engines rely on precise fuel injection pressures — petrol's volatility disrupts this process, risking catastrophic damage to fuel pumps, injectors, and engine components. The damage timeline progresses quickly: within minutes, the engine may fail to start; within hours, fuel system contamination sets in; and within days, irreversible wear occurs if the engine is run. Our priority is preventing further harm — do not attempt to start the engine. Instead, call <a href="tel:08082806346">0808 280 6346</a> immediately.
