Seems to work when others didn't
2008 X type Jaguar kept going into limp mode every few days. After adding a bottle of this to the tank it has been fine. I added a second bottle after about 2 months just to be sure and have just ordered a third to keep in the boot just in case. It may not be cheap, but at the side of new injectors its a bargain. I previously tried STP and Carlube injector cleaner. They both worked for a short time, but not as well as this FORTE. Read full review

Really does work!
Many similar products are dismissed by 'experts' as 'snake oil', but this Forté injector cleaner worked really well in sorting out a rough running problem on our car.
The cleaner was added directly into the fuel filter with a squirt of light mineral oil, engine run for a couple of minutes, then left overnight. The result was a much smoother idle, and a general improvement in driveability.
With the high cost of most diesel injection components, £15 spent seems like a good preliminary step before trying anything more drastic. It won't work in every case, but it certainly did for us.
Excellent service from the seller, too :-)Read full review

Great product.
Best product to use as recommended by most mechanics.
I went against instructions, and put it direct into the fuel filter chamber.
Engine management light went off, after took it for a redline up 75mph in 4th gear for 10mins on motorway.
Car runs better.
Will order off this supplier again very soon, to give car another clean out.Read full review

Diesel fuel in tank additive
I have a Mazda cx5 Diesel. The engine was regenerating at approximately every 70 miles . I added Forte DPF treatment to a full tank and used the car as normal the cx5 only does active regens it will not regen without adding extra fuel to raise the DPF temperature. I noticed an improvement in regens now 100 miles plus . I Highly recommend this product.Read full review

Clearly good for flushing through fuel injectors.
My exhaust was smoking due to a clogged fuel injector. I have used one bottle with each new tank of diesel for several months now and the problem appears to have stopped. Will definitely carry on using it.Read full review

The dogs bits...
What fantastic stuff all of the Forte range of additives are. Van running a tad rough so in goes a bottle and it's as good as new (150,000 miles on the motor) you get what you pay for in this life Forte range isn't the cheapest but it's the best and it actually works, unlike some I could post about!Read full review

Brilliant
Brilliant stuff, cleans your engine and calms it down. I do recommend using it in a long journey not short ones, I filled 50 litres to a 70 litre tank and did 350 miles a good run. Definitely worth it Read full review

Since ‘Greased Lightning’ this is the best additive I have found.
I use two doses (one per full tank), on my Mk3 VW Golf diesel before the MOT and it passes emissions test easily. What more can I say?

Quality stuff
Cleaned up a smoky M47R MG ZT / Rover 75 diesel engine beautifully. Changed the fuel filter, tipped the contents of the bottle in the new filter ran the engine for 30 seconds then let it stand overnight. Took it for a blast the next day and much, much smoother and less smoky. Top stuff Read full review
