Hi All,

Has anyone ever considered using a biodiesel blend to increase lubrication and burn quality on these engines? Having looked at a few scientific studies it is often found that there is a huge increase in lubricity of the fuel when mixing 2-4% Biodiesel with regular diesel.

Note first in class on this scientific independent study

and this one as well

I am considering a 2-3% blend with regular diesel to help reduce fuel pump and injector wear. The only negative is when running strong mixes on a car with a DPF you can get the oil diluted by the biodiesel but I can't imagine that being a huge issue at a 2-3% blend! Only around 25%+

What do you think?

There are some old threads from way back but I think it was for the 147/156 era cars.

Biofuels are just another word for (US) agricultural subsidies.
I would avoid bioderv personally. Same with ethanol.

Quick, get down the Chippy before it shuts!!!
I agree with the above post, bit of a white ephilumt :banana:

there's biodiesel in the pump fuel already...

If you want to add extra lubrication to the fuel use 2 stroke oil, I do and have done on my previous diesels and they run great on it, much smoother and noticably quieter at tickover
200 to 300ml to a tankfull and I use the green mineral oil, saves any hasstle if you get stopped and the tank dipped for red

 

[jtaylor2005]

I have used 2 stroke oil before but I was looking at that and it came as number 7 on their list of improvements with a 162 micron improvement on the test compared to the 415 micron improvement found when using biodiesel mix. However Biodiesel was used at 1:200 but the 2-stroke was only used at 1:50.

I suppose the bonus of biodiesel is that it is actually a fuel so it replaces the regular diesel. Where as the 2-stroke is used as a sort of additive.

I've just measured out 300ml - That's a lot of 2 stroke oil for a tank full of diesel, are you sure?...
Don't think I'll be adding that much 2 stroke, I'm surprised it doesn't smoke like Billio??

I've just read up on this 2 stroke mix, you are correct that 300ml is about right for a full tank, however, trials conducted also concluded that due to the Zinc content within the 2 stroke, this built up & compacted on the injectors giving up to a 6% reduction in fuel flow over 16hrs continual running?
They noticed a spike at 8hrs where they stopped the engine and started again from cold, they concluded that the shock from cold start possibly shifted the Zinc build up but this soon built up again?
There were no significant improvements in power or lubrication on a common rail injection system, final conclusion was that the additives within diesel these days fulfilled the criteria for protecting a Diesel engine with no need for other additives?

There has been one scientific looking trial. However to be honest out of my own experience with using 2-stroke oil in a common rail diesel Peugeot 306 I did notice it was quieter and also smoked a lot less surprisingly.

The thing is that the injectors in that car and the alfa currently were designed during a time when diesel was much more naturally lubricating. It had a higher sulphur content and since the needed to reduce sulphur has occurred a lot of people with older diesels have been struggling with the injector issues.

What I am going to do is trial it in this car. I am going to go for 500ml of 2-stroke oil (Which is low ash type so much less deposit causing and a lot less likely to cause DPF issues) It's a large tank so I don't see it being an issue at all to be honest.

I will then see how things go over the next few weeks and tank fill ups and document what I notice and any MPG and performance changes

Hi mate,
I'm thinking of doing the same on my trip next week?
Shouldn't hurt as a one off.

 

[jtaylor2005]

Give it a go see what happens. A lot of diesel fellas swear by it! One thing to make sure is that the oil is mineral only and low ash stuff

 

[symon]

I wouldn't use two stroke oil if your car has the DPF still fitted.

Even the low ash stuff makes much more ash than Diesel so in the long term it will fill the DPF with ash more quickly.


I did a bit of research on this as I was thinking of adding it to the fuel on my Giulietta but decided against it.

 

[JON156VELOCE]

My 159 when it had the dpf fitted didnt regen any more often with 2 stroke oil than without it. But if you do decide to try it you find your car is regening more often then you might need to rethink using it.and yes, use the mineral rather than synthetic, apparently it mixes better with Diesel and burns better.

Ive just gone by a few recomendations and on how the car sounded, i used it in my 159 from when i bought it at around 55k till when i sold it on 125k and it was running much smoother when i sold it and since using it in my Brera for around 8k miles so far it is definatly running smoother and quiter, whilst in queuing traffic this week I could hear the car beside me, and the car behind me over the sound of my car idling..
As mentioned above years ago Diesel was quite thick and oily, now it is more like kerosene and by the amount of companies making a good living from replacement injectors for diesels a bit of extra lubrication cant do any harm.
Yes 300ml is fine for a tank full, I once added the oil then realised I only had £10 on me so just put £10 of fuel in instead of a full tank and expected it to smoke a bit but it didnt smoke at all.

I'll try it on my jolly next week & see how she goes - I'll report back.

 

[jtaylor2005]

Bought 5l of 2 stroke oil, and a mixing jug for £23 or so all in.

Just mixed up 300ml of 2 stroke and 300ml of diesel to make it easier to pour and then put it in the tank. Will top up my tank to the brim with diesel and then see how things go with the new concoction and report back.

Have you seen this bargain......

Decent. This is what I bought though

Same spec so that's good!
I'm not interested in buying a load just yet, I'll try a tank full first as I don't want to be lumbered with potentially 4.5L of the stuff :driving:
Report back and we will compare findings, just hope it's not bad!!
