I've heard of people doing this, but what are the advantages and is it safe?

well there is allways the search function but quickly (ish)
Older diesels were designed to run on diesel with a nice lubricating aditave (sulphue), that was removed in the 90's and diesel engines (or rather thier fuel systems) were updated to cope, now older diesels show thier disatisfaction at this low sulpher content by basicly being noisy and loosing a few MPG.
So using 2 stroke in an older diesel will make it run quieter smoother and gain a few mpg, my old ford loves it (50 to 1) it starts better, runs better and i gain 4 or 5 MPG on a run (slightly less round town) and it's a hell of a lot quieter, old transit Dis like it the best, modern cars dont need it as i said they are deigned to run on the modern fuel we call diesel.

Not tried it, but a lot of people seem to advocate this for the BMW/Rover diesel.

Could this cause problems with a modern diesels high pressure injectors? Wish everything could smell of two strokes mmmmm.

Somone told me recentyl they put a bit of petrol in a full tank of diesel. Sounds madness to me - but is it common ?

I hope not - but would be interested to know why anyone would do it.

I remember looking for a Fiesta diseasel back in 1990 and one guy I rang up started banging on how his went really fast cos "I put a couple of gallons of petrol in every tank, innit, bruv". I made my excuses and hung up.

(I know it was a good idea in days of yore before winter additives, but not "a couple of gallons" and not to "make the car dead fast innit".)

I think people have put a small percentage of petrol into diesel tanks to stop the diesel 'gumming up' when it gets too cold? I used 2 stroke in my rover 75 and it definitely made it start easier on cold mornings, mpg increased but only slightly.

Any particular engine as both Rover and BMW have made quite a few different ones.

I'm sure the bit of petrol in diesel is to clean everything out. My mom put about 2/3 litres into our old landy (110 2.5 td) then realised and brimmed it with diesel. It was fine but no noticeable performance advantage or any less smoke.

I used to use 2 stroke in my old 2000 E46 320d as did the previous owner.

Probably snake oil, but no ill effects though.

I used to use vegetable oil as well before it increased too much to make it worth the while. Zero ill effects from spring to autumn

This, basically.

Diesel contains wax, which solidifies when temperatures get very cold, although I don't think the UK in general gets cold enough for it to be an issue.

Adding a small amount of petrol to the tank lowers the temperature at which this happens. However, modern diesel, especially in countries where they experience properly cold winters, have 'winterised, diesel, that contains additives to help stop the waxing.

i am wondering weather to try it, as i know the fuel producers have had to make there fuel more environmentally friendly (read gay), so the fuel will no doubt loose some useful properties. 2 stroke might replace these properties.

im quite reluctant to try it without some good feedback for modern engines first.

audi A5 3.0 tdi mapped to 300bhp. not a cheap machine for a 21 year old.

Don't bother - that engine has been designed to work with modern fuels as-is. If you really want to make a difference try using premium fuel (i.e. Shell Optimax etc).

I wasn't aware they'd shared many, but it was the M47R.

I went though a stage of using a little in mine, seemed to make it a bit smoother and less agricultural sounding. I've switched to Millers Ecomax stuff now though as it worked out cheaper

The one which Rover and BMW shared, hence the "rover/bmw". Used in the 75/25 and MG equivelents, M47 i believe?

There is a long thread running about this on the Discovery 2 Boys Club forums.

The general consensus after testing by multiple members is that, even in a modern direct injection turbo (IE the Land Rover TD5 engine), one of those one-shot bottles per tank will give a 1-2mpg increase and smoother power delivery. The theory is that it helps lubricate things like the pump and injectors.

Hi
Well, in for a penny...
Last night, in went 300ml of two stroke to a full tank of diesel.
Car-2008 520d.
My findings, not scientific , and probably mixed with a bit of wishful thinking...
She's quieter
Mpg would have gone above 65mpg if I had more of a run( 25 miles), it was on 64.7 as I pulled into my drive.
What I did notice was more response in every gear, she seemed to be happier in 5/6 gear for longer.
Didn't appear to rattle and roll as much, and at cruising speed she was a smooth as a baby's arse!
There IS a difference, and I will certainly be adding in future wink
