Hi
For anyone mixing 2 stroke in diesel, this may be of interest,
Google: mixing 2 stroke in diesel, a technical study.

It only looks at a 200:1 dosing ratio - I use more than that.

I will continue to use it.

Hi Pete
I am using it faithfully, not so sure now, that's a pretty comprehensive test they've done there.

I have used it for 7 years - but I put more than 200:1 in mine.

I will continue with it - I would need more than one study to stop using it.

Interesting to read in the study that emissions were unchanged. It's for reasons of emissions that I wouldn't add oil to my fuel. The 4M40 is dirty enough already. Sad

Actually you're wrong Simon as the 4M40 was actually a very clean engine, even the MK III 4M41 from the year 2000 is still as clean or cleaner than most modern diesel engines.

Waste of time and money adding two stroke to a 4d56, 4m40 and 4m41.

Yes, it can be clean, remember the size of engine, its output, and the weight it is pulling. Recent studies have shown these engines are very clean for their day, and are still very clean today.

Veg oil? not a fan as they do not get complete combustion and incomplete combustion equals much higher emissions which include soot particles as the only visible indicator as you cannot see the NoX or other emissions, and the soot in the exhaust demonstrates this.

The only way to check emissions is on the meter and fuel consumption has nothing to do with it.

Everything centres around the combustion of the fuel itself and nothing else, better combustion = more complete combustion and the better the combustion the cleaner the engine.

Hi Simon

Fuel economy has nothing to do with emissions, only fuel combustion has a direct relationship.

What you have to remember is that a 4X4 is driving a 4X4 transmission and you have the gearbox and an additional transfer case, in most models you are heaving around over 2 tonnes of metal with the aerodynamics of a pile of concrete blocks, most transmissions connect at the front axle so you are turning two propshafts in 2WD and all this additional friction saps power.

My 3.2 gets around 29 MPG knocking about and around 35/36 on the motorway, but I switch Cyril on (cruise control) and let the system do its thing.
