    Some might say snake oil, but I use mannol additives for like 3 years now. I use burning booster (for gasoline) and no matter if I use e10 here in Hungary or E0 in Ukraine, my Suzuki (previously a 2001s swift, now a 2007s SX4) goes great with it, and the fuel consumption is a bit better too. I use it mainly to preserve the fuel system. The ceramo ester for the oil also worths a shot as being cheaper than the big brands. Thanks for your review. When I fuel up in Ukraine, I can feel that ethanol free gas gives better milage. Even a half of a tank can be felt.

      ​@glchow the only fuel additive that works is Ox-cetane.
      It removes the Entrained and Dissolved AIR thats in the fuel.
      The tiny air bubbles cause fuel injector cavitation .
      Everyone that tries Ox-cetane will see an imediate difference in the way the car drives.
      Usually, after the first tank of fuel a 20 % restoration in lost fuel economy is achieved and smoother running is always achieved.
      I also recommend Engine Oil changes every 5000 miles........Petrol or Diesel.

    I buy a bottle of Redex petrol treatment whenever it’s on Clubcard discount at Tesco.

    The other thing I thought about was if these additives with added detergents are added to the fuel tank and they do breakdown soot/deposits etc, i can only imagine they would cause trouble downstream i.e turbo / sensors.

    I have repeatedly proven to myself over the years that REDEX does exactly what it says on the bottle.
    I bought a cheap Fiat Grande Punto for my son some years ago. It was running poorly and I hoped I could fix it.
    It was so bad, I had to drop it down to first gear to get up our hill.
    I ran 3 tankfuls of REDEX through it (nothing else) and after the third it was a completely different car.
    It flew up our hill in third gear with ease.
    I then fully serviced it and after that it was even better.
    That car served my son well for four years before he bought a new car (new to him)
    REDEX?
    It works. 👍

    • @glchow
      @glchow  วันที่ผ่านมา +1

      My experience has led me to this opinion. The testing carried out on cars and their management software is carried out intensively and on mainland Europe. Europe is a very different driving experience. Generally longer more intense drive cycles. They couldn’t do years of school runs! Add into the mix that it is part of the business model for a manufacturer to have part failure outside of warranty, because if it wasn’t then they would all have longer warranties. Look at the business model of TPS. The VAG group sell you a car on the illusion it is reliable, but have a successful business to collect money from you after the short warranty has expired, and try to stop Patent part manufacturers from making money.

    Been using Redex injection cleaner for over 40 years and my Grandfather before me had been using since the 60s he was a racing Engineer, used in everyone of my cars all Hondas ever since, I use it in my 2020 CRV with a GDI turbo engine the car runs cleaner and smoother and does improve my MPG it does not improve power output or anything like that and nor do I expect it to, I pour an entire bottle in after every oil change around 4,000 miles, Fuel cleaner additives are a must in my opinion more so on modern cars with GDI non port injected vehicles that rely on modern Bio Ethanol based fuels that create more Carbon and corrosion than any fuel before them, I don't care what the manufacturers say its my car and I put in it what I want, I too am an Engineer, I would not put anything in my cars system I did not trust or tested or would cause harm to my engine.

    Perhaps if we could go back to when Redex was the only UCL, we would be better. All the 'clean up' equipment added to diesel and petrol cars which build in failure at a later date. I run a Golf diesel Bluemotion, to avoid the dreaded DPF light coming on I put a bottle of DPF cleaner every 4th tankful as I rarely do long journeys these days.

      It is exactly the same cetane booster used at the refinery to boost diesel to meet B7 European standard and at a higher concentration to produce super diesel.

    • @glchow
      @glchow  ปีที่แล้ว +2

      I’ve not tried it. I’ve heard taxi drivers add up to 5ltrs of petrol to a tank to get better mpg. If both mix with the diesel then they probably would work BUT my worry is that if the car is not used for a couple of days the fuel will separate and the pickup is at the bottom of the tank so the first gulp will be of the least dense fluid. If the engine is common rail this could cause damage to the high pressure pump and then the injectors. It’s not going to be something I will test currently.

    • @paulgilraine3127
      @paulgilraine3127 ปีที่แล้ว +1

      Thanks for the reply. From what I have seen on the videos I've watched two-stroke mixes well and stays in suspension in diesel as long as it's not synthetic two stroke but like you have mentioned I'm sure there will be a chance it could do some damage so it's not something I will be testing on my own car but I might on my works van . Just a small bit to see if it makes any difference to the mpg or the way it drives , I don't think it will do any damage as I drive the van every day and only drive my car at the weekend .

      While I appreciate the simplicity of the EV drive train, the are no simple and cheap additives that can increase your range and performance with EV. We also found out that we are at the mercy of the energy companies if the all decided to increase the prices. The Same can be said for oil, but on a whim a ICE driver can buy fuel from Asda rather than Shell to make a saving.
