“I have managed the Eyemouth Chandlery for nearly 20 years. We have seen significant improvements in vessels suffering from injector and engine issues. Reliability at sea is everything. It is the only product we restock in bulk again and again.”
Craig, Manager
The only product you need.
“Hand on my heart, this product is amazing. It is one thing to have a great engine, but the fuel used determines how well it runs. The real wow factor is when your vehicle goes for an emissions test and the tester retakes it because near-zero emissions are being recorded. That is complete combustion, which gives me around a 10% fuel saving.”
Bill Read, Racing Car Driver
A 5-star winner.
“I do not usually rave about anything, but this stuff is amazing. It turns ordinary fuel into super fuel. Engines run smoother and the black smoke disappears. We service all types of cars and vans, and I have never seen anything like it for sorting out engine-related problems.”
Stevie, Owner and Distributor
This stuff really is that good.
“We were introduced to FORTecX in 2020 and were impressed by its ability to address a wide range of fuel treatment issues in one solution. It provides a more complete and practical treatment approach than most single-purpose marine products.”
Cameron
A real all-in-one solution.
“I cannot praise this product enough. I started using it in mid-2024 across my fleet of vans. We deliver packaging and PPE all around the UK. My vehicles are in the 300,000 to 350,000 mile range, and I can still say they drive like new vans.”
Alaa, Co-founder
No engine issues, no DPF problems.
“I use FORTecX and recommend it to all our customers. It stabilises the fuel and keeps diesel bug away. Customers notice smoother acceleration and an increase in fuel range of around 10%.”
Craig
If you have a gas guzzler, use it.
“We were recommended FORTecX almost two years ago for DPF issues and misfiring injector problems. We added a small dose to the fuel tank, around 35ml for a 70-litre tank. Customer feedback suggests fuel savings of around 10 to 15%, and our taxi drivers tell us they now sail through heavily regulated emissions tests.”
Allan, Co-founder
It genuinely is a unique product.
“I was introduced to FORTecX by a neighbouring farmer. Because we use large agricultural machinery, we had ongoing issues with diesel bug and water contamination, which led to injector problems and black smoke.”
Ben
Ticks all the boxes.
“I was introduced to the fuel conditioner by a training colleague. I thought I would give it a go and have been pleasantly impressed. I noticed the car get smoother about halfway through the first tank, and the gear change on my auto transmission became almost unnoticeable.”
Scott K
Smoother transmission, longer range.
“I run a small fleet of vehicles in our family business with my brother, and I am usually sceptical about any product. The vans now drive noticeably smoother, I am getting more miles from each one and we are saving around £50 to £70 a week.”
Jamie
Fleet savings, quieter running.
“I am a taxi driver from Birmingham. I was given the fuel conditioner to try, and I use it all the time now. My friends and other taxi drivers use it too. My car drives very smoothly, I get more miles per gallon and I am saving about £10 on a tankful.”
Mr Shakil Ahmed
Smoother drive, MPG gain.
“Continuous smooth performance with continuous DPF cleaning.”
