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 Do not start the engine Before the key turns, the problem is in one place. After it, it is in four. That single decision is worth more than anything else on this page. - Stay put if it is safe to Do not try to reach home, a garage, or a quieter spot. Every mile driven moves contamination further down the fuel system. - Get clear if it is not On a verge or a hard shoulder, leave the vehicle and stand behind the barrier. Kit can be replaced; you cannot. - Ring 01293 248666 Have the registration, the fuel type and an idea of the quantity ready.

Praise clusters on two things — speed of arrival, and technicians who do not make a driver feel stupid about a mistake anyone can make. The complaint that comes up most is cost. It is a fair thing to raise: call-out £89 to £199, drain £199 to £1,999, the full price confirmed before a technician sets off, and if the job turns out to be different you are told before further work, not after. ## Questions we get asked **Do you work at night?** Yes, around the clock, every day. A large share of misfuels happen after dark, so the rota reflects that. **What if I have already driven it?** Still call. Most vehicles driven a short distance are recoverable. Tell us how far you got, because it changes the kit we bring. **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. **What happens to the old fuel?** It leaves with us as controlled waste under a waste transfer note. It is not tipped, and it is not resold to you. ## Who you are dealing with Wrong Fuel Carlisle is a service by Forecourt Assistance.
