Tecflow Speed Cleaner is a highly concentrated, powerful fuel system cleaner that cleans the fuel pump, carburetor, injectors, cylinder heads, pistons, valves, turbo, and more.
Speedcleaner is a fast cleaner, suitable for both gasoline and diesel engines, that is added to gasoline or diesel. The goal of Tecflow Speed cleaner is to immediately and quickly clean the entire fuel system and injection system in order to obtain an emission value that is acceptable for a well-functioning engine and for APK requirements. It is also problem-solving and preventative.
Can help with problems such as:
- Hard starting
- High oil consumption
- High fuel consumption
- Poor idle
- Engine light
- Reduced engine power
- Post-injection or pinging
- High emission (APK)
- Condensation water in tank
- Catalyst / soot filter light
Cleans the following parts:
- Lines and fuel tank
- Injectors / nozzles
- Fuel pump
- Fuel injectors
- Exhaust valves
- Valve trains
- Turbo
- EGR System
- Catalyst
- Soot filter
- Lambda sensor
- Cylinder head
- APK / High Emission
Moisture
Moisture will be removed from the tank and lines. Tecflow Speed Cleaner absorbs the moisture and ensures it is burned and disappears from the fuel system.
Dirty injectors / injector cleaner
Dirty injectors are a common problem that occurs when the fuel filter is not replaced in time. When your injectors are dirty or partially clogged, Tecflow Speed Cleaner can clean them so that they spray again.
Fuel system
Tecflow Speed Cleaner is a strong fuel system cleaner. This means that everything is cleaned where the fuel passes. From the fuel tank to the catalyst will be cleaned by the Speed Cleaner.
Fuel consumption
Fuel consumption often increases as the mileage increases. This is mainly due to engine contamination and can be removed by Tecflow Speed Cleaner, reducing the remaining fuel consumption caused by contamination.
Exhaust System
When you want to maintain and clean your dirty soot filter, EGR valve, or catalyst, Speed Cleaner is suitable. It removes carbon and gum build-up from the exhaust system, if the contamination is extreme you should use Tecflow Top Engine Cleaner.
Emission
Speed Cleaner is a cleaner specialized in cleaning the complete fuel system and drastically reduces emission. Speed Cleaner is originally a product produced to help your car reduce emission on average by 40% within 25km.
How to use
How to use Tecflow Speed Cleaner
- First, shake the bottle well.
- Add the contents of the bottle to the fuel tank.
- Drive at least 25km.
- The engine will run smoothly and the emission will be reduced.

Deeply impressed by the speed and effectiveness. I used Tecflow Speed Cleaner in an old ride-on mower that was knocking, smoking and smelling, with a dosage of about 5 ml Tecflow per liter of fuel, directly in the fuel tank. Within minutes the engine ran more steadily, delivered noticeably more power, and the smell and smoke were clearly reduced.

I added a bottle of Speed Cleaner to 20 liters of petrol and after about 25 kilometers I really started to notice a difference. I will order more, excellent quality.
SALOEK –
I needed this because my mechanic had the ‘brilliant’ idea of pouring petrol, which he had drained from a diesel car that had been filled incorrectly, into my tank. Almost immediately I got an emissions/catalyst error, the engine stalled and sputtered, and the cooling fan kept blowing hard. I put this product in my tank and drove 30 km with it. Just like that, the error was gone and the sputtering stopped.

After having my car read out for an error, the catalytic converter fault light disappeared, but after a few days it came back. I decided to try this product and after a few weeks the light disappeared as well.

After only 50 km after adding it, with the engine warm and driving at higher revs, the difference is very noticeable. Certainly compared with well-known competing products such as Wynn’s. The price-quality ratio is excellent. Absolutely recommended.

Does what it is supposed to do. The car starts faster, the engine runs more smoothly and has more power. I also used it for the scooter with the same good results. I will soon order another one for my 4-stroke tools and lawn mower.

The engine of my BMW was not running well. It stuttered at higher revs. Since I put this stuff in my tank, my engine runs like a dream again. It also feels like it has more power and the car has become more responsive. Great stuff.

I needed this because my mechanic had the “bright” idea to pour gasoline, which he had sucked from a diesel car, which had been refueled incorrectly, into my tank. Just about immediately an error message emission problem-catalyst and shutdown and sputtering engine. Also the cooling that was always blowing hard. Put this product in my tank and drove 30Km with it. Hopla, error message gone and no more sputtering.
Valaer –
after reading my car for error, slightly away from incorrect catalytic converter.
but back after a few days.
try this product and after a few weeks the light will also disappear.
Collector76 –
Already after 50 km after adding and having driven at a warm engine and higher speeds, the difference is very noticeable, especially for the well-known competitive products such as a Wynns. Price quality is absolutely recommended

Does what it should do
Car starts faster, engine runs more quietly and more power.
Have also used it for the scooter with the same good results.
Will soon order 1 more for my 4-stroke tool and lawn mower.

Sadoka –
I have a Euro 6 diesel with ticking injectors and usually use a cleaner from LM or Syprin every 10,000 km to get them clean and quiet again. I wanted to try this, so I poured it into an empty tank at the fuel station. Then I added 23 liters of V-Power diesel and drove about 250 km. After that, the noise was still present and had only become louder, and the car vibrates more. Consumption is also about one liter per 100 km higher. I had actually expected much more, given the glowing reviews. Maybe it will still improve during the last 200 km. If that happens, I will of course adjust the review.
Marc –
I bought both products, the one for the oil and the one for the tank. I only added the tank product today. I used the oil product a week ago and yes, the engine is quieter and more stable.
Micjostel –
Two plus points: meets expectations and is easy to use.
Peenutzz –
I once had a customer in a hurry, but he still wanted to take a quick test ride on a motorcycle that was running on one and a half of its four cylinders after standing still for two years. There was no time to clean the carburetors, so after consulting the workshop manager we put Tecflow in the tank. After 10 minutes the engine was running like a dream again, the test ride succeeded and the motorcycle was sold. A few years ago I also got my own motorcycle running well again after a long standstill by putting this stuff in the tank and simply letting the engine idle. It smells strongly of chemical banana.
Eelko123 –
It worked for me just as described. My car was not running completely smoothly at a cold start. After I added Speed Cleaner, I had no more problems!
MMMichel –
I did not think I would notice it, but the difference was noticeable after just a few kilometers on the motorway.
TORRY53 –
This product DOES WHAT IT PROMISES. Also for the lawn mower. It is 28 years old with a petrol engine and recently had problems, namely sputtering at idle and full power. I poured a splash of Tecflow Speed Cleaner into the petrol tank and the result was that the engine runs like new. The spark plug, air filter and similar fuel components had already been replaced or cleaned beforehand, but WITHOUT RESULT. Conclusion: Tecflow helps keep your engine clean and running perfectly as it should.
Enrico Milazzo –
Great lubricant. Since using it, the vehicle is much more economical!
Mulder –
Great stuff, highly recommended and very good!
Civicfan –
My Honda Civic started having irregular idle speed, which was also too high, after standing still for a while and doing short trips. I first warmed up the car in town and then poured TecFlow into the tank. Tip: follow the idle relearn procedure, see YouTube, to relearn the idle speed. Disconnect the power for 5 minutes, reconnect it, leave all electrical equipment switched off, follow the ignition procedure, start the engine and let it idle for a while. Then drive a good stretch on the motorway. The engine management optimizes and the cleaner can then do its job properly. The engine now runs perfectly!
Maagdenberg –
Good stuff, I use it myself too.
Erd1965 –
Very good product.
Jayson –
I am now using Speed Cleaner for the second time. The car no longer stutters and consumption is lower. Tecflow.com is a reliable site. After a small mistake in my order, they immediately sent me a new shipment plus a gift product. Great, I will buy here again.
K –
Not tried yet. I will order it. I read such good stories about it.
H. –
Top product. I put it in yesterday and noticed a difference after 50 km. Superb.
Serdal –
The car, a diesel, was vibrating quite a lot. Definitely recommended. After one bottle the vibration was gone. Great stuff.
Renoi –
Good product and good price.
Poekie69 –
Coincidence or not, but I drove to the vehicle inspection with great concern because of my CO2 emissions and passed straight away! I do not know whether this would also have happened without this product, but I had been having problems with it for two years, so I am very happy with this product!
Kluutje –
SUPER stuff. I used it in my previous car. Today I immediately put a bottle in my new car because the yellow engine fault light was on. You will not believe it, but the light is no longer on. I think there was some deposit around one of the valves. I definitely recommend it.
Anton –
I used it a month ago and after 30 km I did indeed see an improvement in the engine system and fuel consumption. The car started running better.
Jordy Den dunnen –
I thought, yes sure, we will see. But I was curious anyway. Worth a try, why not. Ordered two bottles, one for the car and the other for the scooter and outboard motor. Car: check, accelerates super quickly again with more power. Outboard motor, 2-stroke, much more powerful: check. Scooter? I notice it less there. 2-stroke, okay, but I will try again. It works on the car and outboard motor too, so recommended.
Corne38 –
It does what it is supposed to do for a nice price.
MBvroem –
I used it in my motorcycle and can clearly notice a difference. It sounds better and pulls better.
StevenOrio1897 –
Used in a 2011 VW 1.4 TSI. The engine stuttered at constant revs on cruise control and also seemed to hold back. The problem seems to have been solved after using this product!
5314abc –
I had a strange stalling problem with my Peugeot 2008 petrol car. I went to several garages and nobody knew what to do. On my own initiative I tried this product and honestly, believe it or not, it works. I have had no stalling problems for 3 weeks now and I am super happy with it.
Richard –
I used Speed Cleaner in my Audi A3 Sportback 1.9 TDI and after 30 km I could notice that it started better and regained some power. Great product, so keep it up Tecflow.
Richard –
Great stuff. I will definitely use it more often when needed.
Bram900o –
This weekend my diesel with 145,000 km started stuttering after about 100 km of driving. Since I did not get an engine fault light, I used this product. I cannot say too much about it. I only have the feeling that my engine runs more softly. Since then there has been no more stuttering, although I do not know whether that is because of Tecflow.
richard4444 –
Every time I refuelled, the car started to stutter. The car revved high when stationary, and around 80 km/h it kept stuttering. I first thought it was the spark plugs, but it was not. I have now driven with Tecflow Speed Cleaner for a week and I am very surprised by how nicely my car drives again and no longer stutters. It seems that the longer I drive with Tecflow Speed Cleaner, the more power my car gets back.
Martin –
The engine runs much better when cold. Less smell. More power.
Petrolhead60 –
It does work. After driving 100 km the light was out. However, another 300 km later it came back on. As a temporary solution to get through the MOT, it is fine. For the longer term, unfortunately not.
M.Goorts –
The product lives up to what it promises.
16446262 –
Perfect emissions now. Recommended. Greetings.
Tjebbetc –
Works well.
IskenderAyaz –
I do not see much difference yet, although the sound has improved and so has the power.
Magizn –
Used according to the instructions. For motor vehicles it does not help, maybe for a lawn mower. Before I bought it, I had read quite a bit about it, which increased my enthusiasm. After use, that enthusiasm has decreased. From now on I will refuel with E5.
Derek0700 –
Works amazingly. Added 300 ml to 45 liters in my 3 Series. The next day I did not know what had happened. The car’s throttle response had become 10,000 times better.
Mazzel50 –
I added this product to the tank as described. The power seemed better and the engine knocking too, but after about 100 km I got an error message, the car went into limp mode and could not drive faster than 90 km/h. I had it read out and there were no error messages. This has happened three times now. I do not know whether it is due to the product, but it is quite a coincidence. The dealer told me that these products are not always suitable for sensitive cars. Mercedes B-Class, never had problems with it until I used the product. I hope the error message eventually goes away and that I do not end up with unexpected costs.
vandessta –
I tried this on the motorcycle. I have no idea whether it helps and I do not notice any difference yet. Still 3 stars because it is easy to use and comes in solid packaging including a pouring spout.
FordFez –
I bought this product about a month ago and tested it over the longer term, but in my case the car definitely became less economical. On average, one and a half to two kilometers per liter less than before.
Frankdg67 –
Does what they promise. The engine runs quieter and smoother, and consumption has indeed improved slightly. I have used this several times already. Great stuff.
Cucky –
After also replacing a broken lambda sensor, I used Speed Cleaner in my 2004 Citroen C3 Pluriel because it had been standing still for 6 years. I refuelled, added Speed Cleaner and drove more than 30 km, including a good hard drive. At the MOT, the CO2 value turned out to be extremely low according to the inspector. He wondered how that was possible, and I knew why. Speed Cleaner certainly contributed. For info: 1.4i petrol, 154,000 km.
FBeeckman –
Good product. The car starts much better, even in freezing temperatures.
Josepha1955 –
No problem at the vehicle inspection after using this product in a 2006 diesel.
Piejeken –
Top product.
Heerenvener –
Good price and it cleaned my diesel well. The diesel particulate filter light has not come back!
Kidbaloon –
Good experience.
Rudolfeen –
Very satisfied.
Andrew123456 –
I used this product in a petrol car with about 30 liters of petrol in the tank. After only 50 km the engine ran much more smoothly, almost like new, and at the technical inspection there was no problem at all with the CO measurement, whereas last year it was very close. For now, this is the best product I have used.
Joakime –
Yesterday I added the additive and then went for a short drive. Along the way I stopped and turned off the engine. Waited a minute, started again and the warning light was off. So for now it works. Go to the garage with your problem and you will spend more.
RL1302 –
Excellent stuff. It does everything stated on the packaging. Most importantly, Tecflow ensures a cleaner engine. That is beneficial if you have an older petrol engine, especially for the MOT emissions test.
Ginoooo –
Cleans well, the engine management light even went out.
Saar1948 –
I was afraid I would have to replace or have the EGR valve cleaned. After using another product that had no effect, I bought this one. After adding it and refuelling, my Ford Focus runs great again. No hesitations, no stuttering and no loss of power. The orange light has also not returned after I cleared the error. In short, it saves a lot of money. I can really recommend this product.
Foland –
I have been using this product for years in my cars. It is the only cleaning product where I really notice a difference after adding it. Great stuff.
Spidermanerik –
For my motorcycle I needed a fuel system cleaner after it had been standing still for a while. Fast delivery and excellent stuff.
Reviewer378 –
I used one bottle for the car, diesel, and the other for the motorcycle, petrol, but it really had no effect at all.
Chareltjllll –
Good product and very fast delivery.
ManSven –
Great stuff. I had checked beforehand and the catalytic converter in the engine was dirty and black. After the product, the cylinders were a bit cleaner and deposits were gone, although not completely. The catalytic converters also look nice and clean again.
11041963 –
Used before the MOT on my Twingo diesel with 276,000 km on the clock and the emissions were approved immediately.
Oleksiy82 –
I ride a GSXR 750 motorcycle from 1993 with a carburetor. It had some trouble starting cold, and above 100 km/h the speedometer needle kept moving up and down a little. Definitely contamination in the carburetor and possibly in the injectors. One bottle of this, a fresh tank, a ride to work on the motorway and some decent revs. And voilà, it runs perfectly. No problems anymore! Many thanks to the makers of this product and for the fast delivery. Good job!
1stan –
After adding the product, my consumption went up slightly, but it is returning to how it was before. At the inspection, however, I passed with flying colors.
JohanvGinkel –
Used for my outboard motor. Worked fine in a 12-liter tank, nice and strong. I soon heard that the engine was running like new again!
Dendraaier –
Thanks to this product, my car passed the technical inspection. No exhaust gases above the limit.
Pietergee –
Emissions were okay again at the re-inspection.
Wijathle –
Works great, as described.
Rogger1952 –
At the fuel station I poured the product into the diesel tank of the light truck, added 30 liters of diesel, and a few kilometers later Tecflow Speed Cleaner was already working. The vehicle drives perfectly again.
Pasje2 –
It works.
Hawar75 –
Does not work at all.
Terwanen –
Satisfied.
Koffie7 –
One of the few additives that really works!
Cabriopower –
A pity that I ordered Speed Cleaner and received the regular Cleaner 101 instead, because that is not the same.
5654798 –
The effect is difficult to assess. I had contamination in a 100-liter diesel tank and it was still there after the product, possibly because it had not worked long enough.
Richardgerrits –
Works fine for an older car.
abs59 –
Easy to add and the engine keeps running without problems. Smoothly passed the MOT.
stesa –
After failing because of CO2, I used this and the CO2 was back within the limits. A petrol car.
PGies –
Price-quality ratio is excellent.
Sven Van der Hoorn –
This is a top product that really works! I tested it myself with cameras before and after using the product. I had not used any products for 2 years. I had bought a poorly maintained car with a blocked catalytic converter and a thick layer of carbon on the pistons in the cylinders. After using the product twice according to the instructions, I can read the lettering on the pistons again and nothing is visible anymore. The catalytic converters are completely clean again and look like new inside.
