It is written from job data, invoices and customer reviews rather than from other people's websites — which is why the prices, the timings and the failure patterns on these pages match what actually happens on the job. The canonical author profile for the whole network is at https://forecourtassist.co.uk/experts/rambo-s/. ## What we are not There is no Wrong Fuel Sunderland garage, workshop or premises. This is a mobile service: a technician travels to the vehicle. We say that plainly because a local phone number and a local name can imply a local building, and we would rather tell you than let you assume. **Legal entity**: Fuel Fixer Ltd **Company number**: 08520551 **Registered office**: Fairway House, Portland Road, East Grinstead, RH19 4ET **Operator**: Forecourt Assistance **Group**: Fuel Fixer International **Owner**: Stockbridge Capital Holdings **Phone**: 01293 248666 ## Four point eight, and why it is not five 2,190 Trustpilot reviews average 4.8. Happy customers write about patience: a technician who explained each step instead of hurrying, at an hour when nobody wanted to be standing on a forecourt. Most of the missing tenth is money. That is understandable, so the numbers sit in plain sight — call-out £89 to £199, drain £199 to £1,999 — and every figure is agreed by phone first, never revealed on arrival. ## 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. **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. **How long will I be waiting?** Arrival depends where you are across SR1 to SR6, DH4 and DH5 and what is already running. You get a realistic window on the call rather than an optimistic one. **Do you cover all of SR1 to SR6, DH4 and DH5?** Yes, from one rota — so being at one edge of the area rather than the other changes the arrival window, not the price. **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. **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. ## Across the network Wrong Fuel Sunderland is one of the sites run by Forecourt Assistance, a trading name of Fuel Fixer Ltd, part of Fuel Fixer International, owned by Stockbridge Capital Holdings.
