Frequently Asked Questions

What is the fastest way to fix putting the wrong fuel in my car?

The fastest way is to contact a specialized mobile wrong fuel mechanic service like Wrong fuel help. They come to you, drain the contaminated fuel, flush the system, and refuel with the correct type, often within an hour.

How much does it cost to fix wrong fuel in a car?

Can I drive my car after putting the wrong fuel in it?

What happens if I accidentally put petrol in a diesel car?

What happens if I accidentally put diesel in a petrol car?

Diesel in a petrol car is less immediately catastrophic than petrol in diesel but can still cause significant issues.

Most standard car insurance policies do not cover accidental misfuelling. Some specialized roadside assistance plans might offer limited coverage or discounts, but it's best to check your policy details carefully. Typically, this is an out-of-pocket expense.

How long does a wrong fuel service typically take?

A complete wrong fuel correction service, including draining, flushing, and refuelling, usually takes between 30 minutes to 1.5 hours, depending on the vehicle and the complexity of the situation. Mobile services aim for maximum efficiency.
