## What should i do if i put diesel in a petrol car: what to do
Rarer, less destructive, still needs draining.

## Litres matter less than you think
The quantity of wrong fuel is rarely what sets the price. Distance travelled through the system does. Fuel that never left the tank comes out with a pump and a hose. Fuel that reached the high-pressure pump may have begun wearing it, and fuel that reached the injectors may have carried that wear with it.

## Step by step
The single rule Leave the engine off. Everything else on this list is secondary to that one instruction.
- Do not reposition the car Pushing it into a bay feels considerate but it disturbs the fuel. Stay put unless you are in danger.
- If it is dangerous, get out On a verge or live road, everybody out on the side away from traffic and behind the barrier. Then call.
- Call 01293 248666, day or night Answered around the clock. Describe the vehicle and what happened; the full price is confirmed on that call.
- The fix, where you stand Drain, flush, refill, prime and run-up, carried out at the roadside or on the forecourt.
- Finished properly The waste is taken away by a registered carrier with the transfer note, and you get an invoice.

## Rated 4.8 out of 5
From 2,190 Trustpilot reviews. Reviewers consistently pick out arrival times and the fact that technicians talk them through what happened rather than just taking the keys.

Where reviews are critical, it is almost always about price. Rather than ignore that: the call-out is £89 to £199 and the drain £199 to £1,999, quoted in full on the phone before travel, and we would rather lose the job on the call than argue about it on the forecourt.

## Questions we get asked

**Is there an out-of-hours surcharge?**
The call-out is the call-out. Whatever the total is, you hear it on the phone before anyone travels.

**How much does it cost in Sunderland?**
Call-out £89 to £199, drain £199 to £1,999. The full price for your vehicle is confirmed on the phone before a technician sets off, so there is no surprise when we arrive.

**Will it have done damage?**
If the engine was never started, damage is unlikely. If it ran, the risk rises with the distance driven — which is exactly why we ask.

**Can I just top it up with the right fuel?**
No. Dilution does not fix contamination, and driving to a filling station to try it is the mile that turns a drain into a repair.
