I read quite a bit about adding 2 Stroke oil and the consensus seems to be that it replaces the Sulphur that 'they' removed which acted as a lubricant.

I can say that the engine runs quieter and there is an improvement in fuel consumption - I get around 29-30 mpg pottering about and 38-39mpg on a run. That's with a 1.2 T/box and a roof rack at a steady 65-70 mph and the odd dash up to 75 to get past stuff in the first lane.

Of course, it helps that with two RD Yamahas there's always loads of 2 Stroke oil kicking around... 👍😃👍

A mate recently tried using some 2 Stroke oil in his 2015 Peugeot Boxer (big van). The best he's ever had out it was 32mpg but on a run down to Manchester he got 41mpg - and is a happy bunny. He didn't notice a reduction in noise but it's probably got better soundproofing than my Landy.

👍👍

Just dumped a load of 2Stroke into Miffy as she has been sat still for a few months. Definitely quietens her down a bit. No idea about the fuel economy though just yet.

from what i what i read, it helps with the lub rather the MPG.

And that there is 2 Strokes worth IMHO... Interestingly after a good first run with 2 stroke oil in the tank the exhaust note has changed, deeper... Somehow... Cannot see how it is connected

Don't know if it's available in the UK, but I'am running HVO100 at the moment.

It's a plant based diesel, lot's of benefits for the environment (ie 95% less CO2) but the engine is running also a lot smoother and no black smoke anymore.

Only 1 very little setback, it's about 25% more expensive than regular diesel.

It is not common. There was a place in Shrewsbury years ago that sold biodiesel at the pump, but no longer.

So how much are you 2 stroke users adding per tank?

To be environmental friendly you don't only have be a millionaire but also have 3 university degrees.

Because bio diesel isn't the same as HVO (also called blue diesel).

HVO is Hydrotreated Vegetable Oil. And one of the plupoints is that it doesn't contain bio diesel. If still anybody is following and wants to know more just ask. a defender from 1984 pretending to be a puma with a touch of Range Rover

Would this help a potentially noisy fuel pump, that seems to be whining on idle?

Interesting read on using 2 stroke oil with Diesel engines.

The Truth About Adding Two-Stroke Oil To Diesel In Modern Common Rail Engines

Matthew Bailey MAICD Matthew Bailey MAICD

Published Jul 1, 2016

It seems counter-intuitive to be utilizing 2-stroke oil in diesel on common rail, low emission vehicles. The actual premise behind adding 2-stroke does carry weight in certain instances. Vehicles equipped with Bosch, Delphi, or even Seaman’s fuel systems generally don’t need it. Therefore, your unlikely to see a significant change in engine performance or noise with the use of 2-stroke in diesel.

However, if you have a 2005-2012 Denso Common Rail equipped system, your vehicle will most likely notice significant changes.

The Theory
You need 2-stroke premixed oil, at a ratio of 300-to-1. This equals about 3ml per litre, of mineral based, low-ash 2-stroke oil. The reason why this mixture creates a beneficial difference is quite simple. With Denso Common Rail operating systems, nearly all failures we have seen at Bailey’s Diesel are seizure related or seizure based failures. The injector becomes sticky; it generally loses tolerance and shows symptoms such as cold knocking. The idea behind adding 2-stroke oil therefore makes a lot of sense, because we’re adding lubrication where the main failure mode is seizure related.

The other interesting thing is that when we fitted all of our injectors with DLC coated injectors, we noticed a significant difference in the engine noise and smoothness. The DLC coatings applied inside our injectors create a permanent, very hard and low friction surface . So I thought if the low friction was worth a try, we should test this 2-stroke myth, and we were surprised when it actually worked quite well.

Our Conclusion
So the reality is if you have genuine Denso injectors or the original injectors in the car, and it’s pre-2012, then adding a little bit of 2-stroke will create a longer service life for the injector, but also make it a little quieter and smoother in its daily operation.

The general premise behind it: mineral-based, 2-stroke, low-ash and 3mil of oil per litre.

Hope you enjoyed the article. Please feel free to contact me (0403) 243-786

Thanks,

Crikey..!! It's true...👍😃👍

I add 300ml to a full 75 ltr tank (I think TDi 110s have an 80 Ltd tank..??) which equates to 250:1

I actually told the MoT tester that I had 2t oil in the fuel and his response was "Hmm, this could be interesting..." but she passed the emissions test with flying colours.

Happy days.... 👍👍👍 2002 Land Rover 110 Td5 Utility

I’m not sure how “DPF friendly” two stroke oil is so I will stick to millers as a additive each time I add fuel and forte once a year.

That’s essentially what I do Ian 👍

I am following this subject with interest. While being sceptical I do note a quieter running of my Td5 after adding an off the shelf additive. Maybe it is cleaning the injectors but I suspect it changes the Cetane rating, like apparently 2 stroke oil does too.

Cetane rating being the octane rating of Diesel and I understand raising it makes for less diesel knock. At least so the theory goes

Last one from me - 2t oil has different (Japanese) specs always shown on the label. The current readily available ones are;

JASO FB - the most basic 'classic' oil.
JASO FC - 'middle of the road' and what I use in my TD5 (EGR blanked and no exhaust Cat). I could use 'FB ' in her but it was a four litre bottle of 'FC' on offer at Opie oils...
JASO FD - the best quality - low ash, low smoke and what seems to be recommended for more modern engines. This is the one that was used by the Freelander 2 boys and the one I would go for If I had a Puma.
