COMMERCIAL USER · SCOTLAND

I initially came across FORTecX Eco and decided to try it on my own vehicle. Having monitored fuel consumption and a noticeable change in engine behaviour and smooth driving, I offered it to my clients. The result for them is the same: around 12% fuel saving, smoother performance and continuous DPF cleaning.

WAVERLEY GARAGE – BATHGATE

I don’t really rave on about anything . But this stuff is amazing . It turns fuel into a super super fuel . Engine runs smoother and no black smoke . We service all types of cars and vans . I’ve never seen anything like FORTecX as it sorts out a lot of engine problems .

We have become main distributors here in Bathgate and I have just received my second batch of around 150 bottles . I have sold 4 of 250 ml bottles today and have another two 1 litre bottles going out by repeat order from a parcel delivery firm .

This product really does do as it claims . I highly recommend you try it . My customers rave on about how their vehicles feel lighter and the fuel savings are incredible .

You can call my garage anytime to ask me in person . There’s no better proof than when you try something yourself .

I bought it , tried it and now sell it to my own customers .

You only trust two people in life , your barber and your mechanic .

I don’t know haircuts , but motors .. I’m the guy , and this stuff is really that good .

M&S AUTO SOLNZ – WEST LOTHIAN

We were recommended Fortecx almost two years back for our DPF issues and misfiring injector problems . We decided to take the advice and dosed up the small amount into the fuel tank . Around 35ml for the 70 litre tank .

We started the van and noticed the thick black smoke turning white within the first minute and the shaky engine start to run smoother .

Over the next couple of weeks out of curiosity we started to test the emissions on our gas analyser ( MOT Ststion ) and noticed that the emissions were coming down drastically . Black smoke is just unburnt fuel .

We started to use FORTecX across our fleet vehicles and now recommend it to our customers also .

It seriously is a unique product .

Customers on feedback are saving around 10-15% of their fuel and our taxi drivers have told us that they sail through their heavily regulated emissions tests .

Overall highly rate it.

INTELIPAK – GLASGOW

I cant over glorify this stuff . I started using RemNOX now FORTecx in mid 2024, in my fleet of vans . We deliver packaging and PPE all around the UK .

My vehicles are around the 300-350T in mileage and I can still say , they drive like new vans .

I have no engine issues , and no DPF or idle problems. Most important I easily get around 40+ mpg from a tankful which more than pays back the small investment .

I ask all delivery drivers , we use a lot of fuel , consider saving £10 on each tankful . With FORTecX you do .

FARMER · NORTH LANCASHIRE

I was introduced to Fortecx from a neighbouring farmer. Using large agricultural machinery we always had issues with diesel bug and water issues . Resulting in bad injectors and black smoke .

The fuel conditioner ticks all the boxes and I now dose my 4000 litre static tank and use it on all farming equipment and also my personal vehicles .

★★★★★

INDEPENDENT JAGUAR – LANARKSHIRE

I use Fortecx and recommend Fortecx to all our customers . A lot of our cars are E10 but should run on E5 fuel as the ethanol splits if the cars are driven and are left for long periods of time . The linings and connectors on the fuel lines corrodes .

Fortecx stabilises the fuel and keeps diesel bug away . Customers notice a super smooth acceleration and an increase in fuel range of around 10% .

If you have a gas guzzler , honestly use Fortecx.

★★★★★

CLYDE OUTBOARD SERVICES – GLASGOW

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.

What we particularly like is that it tackles a broad spectrum of problems associated with fuel quality and storage. Other products on the marine market tend to focus on only one or two specific aspects of long-term E10 fuel use, whereas FortecX provides a more complete and practical treatment approach.

TAXI DRIVER · BIRMINGHAM

I am a taxi driver from Birmingham. I was given FORTecX Eco Fuel Conditioner to try and I use it all the time now and my friends and other taxi drivers use it too. My car drives very smooth and I get more miles per gallon. Emissions testing for taxis is very strict and I am very happy that my car passed its strict emissions test successfully. I am saving about £10 on a tankful.

★★★★★

BATHGATE · WEST LOTHIAN

I was introduced to FORTecX Eco Fuel Conditioner from a training colleague. I thought I’d give it a go and have been pleasantly impressed. I drive a sporty 330d BMW, and speed is key. I noticed the car get smoother about halfway through the first tank and the gear change on my auto transmission became almost unnoticeable. Acceleration improved and I’ve noticed a huge difference in my mile range per tankful.

★★★★★

RACE CAR DRIVER – LANCASHIRE

I tried FORTecX initially through racing in my Legend race car. I have been using it in my road cars – a Mini and a Porsche 911.

Hand on my heart, this product is amazing. It’s 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 MOT tester retakes the test because near-zero emissions are what is registering. That’s complete combustion, which gives me around a 10% fuel saving.

NORTH LANARKSHIRE · FAMILY BUSINESS FLEET

I run a small fleet of vehicles in our family business with my brother and I’m usually sceptical about any product. I started using FORTecX Eco Fuel Conditioner doubtful of the claims, but the vans now drive noticeably smoother and I’m getting more miles from each one, saving around £50–£70 a week. The black smoke in the mornings has gone and the engines are quieter.
