6 Wrong Fuel Myths That’ll Cost You Big (And One You’ll Wish Was True)
You just misfuelled. Panic hits. You Google. And suddenly everyone’s an expert—except they’re wrong. We’ve drained 500+ tanks. Here’s the truth, no fluff.
Myth 1: “Top up with the right fuel and it’ll sort itself out.”
Wrong. Mixing petrol and diesel clogs filters, kills pumps, and turns your engine into a £1,000+ repair.

Myth 2: “Diesel in petrol? Just drive it home.”
You’ll get maybe two miles before it coughs, stalls, and dies. Then you’re calling a tow truck—£150 extra—plus the drain. Don’t.
Myth 3: “Insurance will cover me, right?”
Nope. Most policies call it “driver error”—you pay. We’ve seen people lose £800 because they hoped. Check your small print.
Myth 4: “I’ll just siphon it out myself.”
Sure—if you want fuel in your lungs, a fire risk, and a garage bill for a ruined pump. Pros use sealed pumps. DIY? Bad idea.
Myth 5: “If I don’t start it, no damage.”
Fuel sits and corrodes lines, seals, injectors. Wait a week? New parts. Drain it same day—£250–£350. Wait? Double that.
Myth 6: “I’m not stupid enough to do this.”
Everyone says that—until they grab the wrong nozzle at Tesco. We’ve fixed doctors, builders, even a vicar. You’re not alone.
