The argument as to the efficacy of adding 2T began when a German engineer working for a well known German car manufacturer posted how the Company added 2T at a ratio of 200:1 when they took their cars to countries with questionable fuel standards. She (yes she) couldn’t name the company for legal reasons and her own protection but went on to say how German taxi drivers had been doing it for years. There’s a clue there.

Those against, and of course they have a right to believe it wrong, love the phrase “snake oil” but never back it up with evidence. They use modifiers like possibly, might or maybe you will damage your engine, but never offer evidence.
There is no proof, but there is very significant evidence that it will do no harm and those who use it see benefits.

As I posted before, I have been doing it for years and believe in it. I do not believe it will improve MPG but it certainly reduces diesel clatter, and not because of reduced cetain. It also helps to maintain a cleaner engine. For example my MAP sensor, like most, was covered in thick tarry gunk, but after cleaning and using 2T for 6 months it was fairly clean.

But the golden rule applies, if you like it do it. If you don’t then don’t use it, but if you are going to say it damages the engine then post some evidence.

Reminds me of the time some one told me that when I fill up the tank with diesel put a litre of petrol in there and the engine will purr with better mpg and it will clean the piston heads......

You have no clue how much engineering goes into designing of an engine and how many hours are spent in testing them for optimum performance.

If your back yard engineering can beat multi million pound worth of research .... you are a genius.

Everyone is free to believe whatever they want to read off the internet. We all make our own decisions about what is safe to put into our bodies - or fuel tanks

Here's an interesting read-- beware its very long lol its about fuel additives

In terms of my sprinter which I had from new, I tried the 2 stroke oil and it made a huge difference to the sound and smoothness of the engine. You say it's because of the slower burn, I'm not convinced of that because the performance didnt suffer. From 100,000 miles to 350,000+ when I sold I ran it on home made bio diesel using a bio buddy. The 2 stroke oil with this made a difference but not so dramatic, then engine did run sweet as a nut all of it's life and is still going strong.
Lots of things I don't buy into with firm evidence eg premium fuels, the 2st I did measure the performance difference and there wasn't any only my MK 1 ears which showed quieter and smoother running. i did try doing a few tankful's without the 2st and my partner noticed immediately when I added the 2st again. BMW i3 Electric Car

I find this subject facinating, I've said before I work for Cummins who make a wide variety of diesel and gas engines of many sizes.
I totally agree with jackcrammerr- The guys that understand the chemical thermal reaction taking place inside the engine and have the knowledge to tweak that to get as perfect a combustion as they possibly can whilst balancing emissions, power and fuel economy are in my opinion exceptionally clever people.
I asked them, they said snake oil! probably won't do any long term harm, extra lubrication is doubtful - our piston rings are designed to provide optimum upper cyl lubrication already, we would need to do tests to see if it soots up DPF any quicker - the DPF can probably cope.

At 200:1 it's probably just getting burnt, it will be raising the hydrocarbons in the exhaust but would need to test (lol engineers always want the data) again aftertreatment probably copes with that too.
Then I asked if they would add it to theirs - No - not without data to prove it has benefit - which they seriously doubt.

jackcrammerr - you did make me smile "you are a genius" Anything can be made to work if you fiddle with it long enough (and have deep pockets|)

But all additives are the same, lots swear by dr tranny shudder fix

Aren't

My question if this additive increases power and noise but more importantly reduces emissions at the same time the fuel manufacturers would add it themselves to the fuel stock and or the vehicle manufacturers would demand it to help meet emissions and performance requirements 🤷

I don’t like anecdotal evidence, performance and emissions should be easily to prove by empirical data from a rolling road and on road measurements of noise, emissions, power output and on road performance, combustion data like knock, flame speed and temperature etc and just leave out the ‘it seems’ or ‘or it feels’., just measure it 👍

The world of additives stinks of snake oil, very few have been independently proven to do anything other than relieve you of money.
