If you’ve just realized you put the wrong fuel in your vehicle, the very first thing that flashes through your mind—right after a bit of panic—is: "How much is this going to cost me?"

It’s a completely fair question. No one plans to misfuel, so it’s always an unexpected expense.

The good news is that resolving a fuel mistake doesn't have to break the bank. However, the way you choose to fix it will drastically change your final bill. Let’s break down the actual costs of a mobile fuel drain versus the alternatives so you can make the smartest, cheapest choice for your wallet and your engine.

The True Cost Breakdown: Roadside Rescue vs. Main Dealer Garage

When you misfuel, you generally have two choices: call us to fix it on the spot, or have your vehicle towed to a main dealer or local garage.

Here is how the costs realistically compare:

Option 1: Wrong Fuel Emergency Mobile Service

Average Cost: £130 – £250 (depending on your location, vehicle type, and fuel volume).
Towing Fees: £0 (We come directly to you).
Time Lost: 30 – 45 minutes once our technician arrives.
How it works: Our specialist technician drives out to your exact location (whether you are stranded on a motorway or stuck at a petrol station forecourt). We use specialist, spark-safe pumping equipment to drain your tank, flush your fuel lines, give you enough of the correct fuel to get moving, and safely dispose of the contaminated waste.

Option 2: Main Dealer or Traditional Garage

Average Cost: £500 – £1,500+
Towing Fees: £100 – £200 to get the car to their workshop.
Time Lost: 1 to 3 days waiting for an open workshop slot.
How it works: Because standard garages don’t usually have rapid mobile extraction equipment, they often quote to replace the entire fuel system, injectors, and fuel filters. They will charge you their standard heavy hourly labor rate, plus the cost of towing and contaminated fuel disposal.

What Factors Affect the Mobile Fuel Drain Cost?

Not every misfuelling situation is identical. When you call us for a quote, we calculate the price based on a few quick factors:

Have you turned the ignition? If you realized your mistake before turning the key, the wrong fuel is sitting safely in the tank. This is a straightforward drain. If you started the engine or drove away, the contaminated fuel has entered the fuel lines and engine system. This requires us to do a more thorough system flush, which can slightly increase the cost.
The Amount of Fuel in the Tank: Draining a full 70-litre tank takes slightly longer and costs more for us to safely dispose of than a tank that only has 10 litres of the wrong fuel in it.
Your Vehicle Type: Standard cars and small vans are highly straightforward. Large commercial trucks, specialized fleets, or high-performance supercars can sometimes require complex access to the fuel lines.
Time of Day: While we operate 24/7, a call-out at 2:00 AM on a bank holiday Sunday may carry a slightly different emergency rate than a call-out at 2:00 PM on a Tuesday.

Does Car Insurance Cover Misfuelling?

Many drivers immediately call their insurance provider hoping it will be covered.

In most cases, standard comprehensive insurance does not cover misfuelling as standard—it is often classified as a "mechanical breakdown due to user error" and requires a specific add-on policy. Even if your insurance does offer a misfuel rescue service, you will likely have to pay a hefty policy excess (often £150 to £250) and risk losing your No Claims Bonus.

Calling our independent mobile specialist team directly is almost always faster, cheaper, and keeps your insurance premium intact.
