2 stroke oil in diesel

stevenlizuk · Post by **stevenlizuk** » 08 Mar 2010, 00:14

Hi all,

I have started this thread on the Pug section but as my engine is in Citroen's too and this is a busier section I thought I'd give you boys a punt at it too.

I've started a thread on the 406 Owners Club forum that has turned into a bit of a monster so thought it might be interesting to see how it rolled here.

Has anyone added 2 stroke oil to their fuel in the past and if so can you elaborate as to how it effected the performance of your car if at all?

At this point I have just started adding this to my fuel in my old bus and so far the results have been only beneficial with reduced smoke under load and a quieter (less rattly sounding) engine.

Any input from this?

Cheers
Steve

I once added model aircraft fuel to the tank of a Morris Marina

Only benefit was it made it smell like a dragster. Sadly (or not), shortly afterwards it dropped a valve and ended up having the engine replaced.

I can't see it doing any harm, after all, our dads used to swear by a shot of RedeX back in the olden days. Remember the old red dispensers of RedeX - one shot to a gallon of petrol...

Upper cylinder lubricant is a fine idea but pointless really nowadays as the crankcase ventilation system (especially on a TD engine) sees that plenty of oil mist gets into the inlet tract and this will do the same job.

Diesel has lubricity additives already present to lubricate the injection pump so this does the same job.

In a petrol engine, it just may have some beneficial lubrication/clearing effect on the injectors and maybe quieten down a noisy in-tank pump. very tenuous though.

Apart from that, all I think you are doing is depriving your lawn mower of it's life-blood...

More than likely as a result of pretty destructive detonation Stempy

Well I was a teenager at the time so that explains it.

My dad used to put Redex in his Morris Minor.

Nor at my age when you remember dad using it

Not seen the old RedeX guns for years now. Come to think of it I've not seem the bottles of it for years either....

I only had just the one dad Paul

I was meaning all our dads collectively...

This is the best picture of the RedeX "gun" I could find...

Iv'e read a lot about this on the net and have been using it on and off for over a year (When i can remember to put it in)I can't say that its made a noticable difference but also can't see it doing any harm,When you change the filters on an HDI and see the iron filings in the bottom of the filter housing then anything that can slow down the wear on the pump is ok by me.Make sure it's LOW ASH and MINERAL, don't use a synthetic based oil.

I must be a really old f@rt then cos I use their injector cleaner in my Xantia. To be honest apart from the boost whilst it's in the tank, there seems to be little benefit. My view is if it prevents a build up in the injectors, then it's probably worthwhile.

I see where your going with this Jim but I'm thinking more along the lines that my 10 year old 2.1 wasn't ever designed to run on low sulphur fuel or bio-diesel and modern fuels have much less sulphur and contain 5% bio.
The object is to add something that counters the lack of lubrication from the removal of the sulphur and the addition of the bio.

Thoughts?
