I think the clue to the lie that it damages FPF or cats is in the fuel filler cap ... Check the oil every 600miles it says.....So if it needed topping up that would mean way more than 200ml had passed the piston rings.
Mine uses no oil since I had it 3000 miles ago but I do use 10w40 Always listen to old people or when they die you will live on in ignorance.

And the zinc in mineral 2SO can increase injector fouling as well as contaminate catalytic converters. 2012 SDV6 - it's missing a couple of cylinders

Just because you call yourself an engineer, it doesn't mean you 'know it all'.

Engineers signed off the crap regen software that destroys the crap designed crankshaft in LRs V6 engines.

Engineers signed off the Horizon IT system that failed so many.

And the list could go on.

One of the most used and respected fuel additives (I can't remember the name) in the USA is actually manufactered by a leading fuel company.

The exhaust after treatment sysytems are quite capable of failing on their own for no apparent reason, and truck manufacterers have to allow for good fuel in the civilised western world and also crap fuel as available in the east, on the same journey, so it's not a use once and you've knackered your engine scenareo.

Ah, the old "don't trust experts" line of argument.

Engineers are often overruled by managers and accountants. If allowed to get on with the job, engineers put men on the Moon.  2012 SDV6 - it's missing a couple of cylinders

Whilst I will listen and take note from engineers or people who obviously know what they are talking about, there are some on here who have an opinion on everything and view any alternative argument as rubbish, or as is becoming more apparent, any view from certain people, irrespective of the subjuct.

To remind those who fall into the above catergory, I have said on this subject that the use of 2SO on early non high pressure systems could have an advantage, but on modern high pressure ones, possibly not, and it is the later which has after combustion systems in place.

As has been said elswere on another thread, no-one knows what experience all members have, so sometimes it might be sensible to listen and consider anothers theory rather than dismiss it out of hand.

Good points, Dave. It is worth noting that the discussion is about adding 2SO to a modern engine with after-engine treatment systems, not an old "low tech" engine.

When the whole 2SO thing was brought up years ago I, along with others no doubt, spent some time trying to find evidence that it was beneficial (or at least not harmful). Lots of "I tried it and it was great" and some "here are real experiments that show no benefit and might suggest harm". Neither are definitive but I would rather err on the side of caution when presented by those two sets of evidence.

Others may choose to disagree, but I think advocating that others add 2SO to a modern engine's fuel system is not wise without strong evidence of benefit. 2012 SDV6 - it's missing a couple of cylinders

Totally agree, they're quite capable of throwing a wobbly treated as suggested by the people who make them, so why add another option for disaster.

I think the only stuff I’d put in fuel is Techron by Chevron/Texaco. When I was in the US I’d often get Chevron fuel which has Thechron in it. With Chevron fuel I could generally get an additional 50 miles out of a tank of fuel. This was in my 2.8 VW GTI, 4.0 P38A as well as my wife’s 2.4 Toyota RAV4 and noted over years of driving, not just a one off tank of fuel. My brother who has a 3.0 Toyota Highlander also noted the exact same results when he would use Chevron fuel. So, if I just absolutely HAD to put something in my diesel, Techron by Chevron/Texaco would be my only option. 2011 RRS HSE Luxury 3.0 TDV6 Fuji White on Ebony/Ivory

While relatively fresh here, you must be popular in other circles with your polite demeanour.

We all know already, if the facts do not support your personal beliefs, you blame the facts and resort to slurs. Perhaps it's time to find yourself some community that accepts this? Regards etc.,

Prove it with some facts or please shut up (we all know how you love facts/data).

I've already given enough figures based on my own experience of something like in excess of 1.5m miles.

So please stop arguing for the sake of arguing and increasin your post count.

So how have you managed get personal experience of that many miles?  2023 P440e SE Dynamic on order -cancelled

With the cost of 2 stroke oil and the quantities added per tank full being 400ml is it cost effective? Always listen to old people or when they die you will live on in ignorance.
