Adding 2 oil stroke in diesel fuel

**Nostrodamus** · 17-02-12, 08:07

Sometime ago there was a thread that mentioned the benefits of adding 2 stroke oil to your diesel fuel.

Now a bit of time has passed I wondered if anyone still does this and has anyone noticed any benefits or has it caused any problems?

How much do you add and how often?

Thanks

I started a thread on this and may be the one you are referring to. My engine started to smoke after adding it and ended up with some other problems which resulted in a complete rebuild. I would not use it again.

Were the problems down to the 2 stroke do you think and what sort of problems?

Why on earth would you do it? Are you trying to outguess the engine and fuel manufacturers who spend millions researching optimum solutions, which you then think you can 'improve' by adding a shot of gloop?

Just wondered if it made a difference as in the Mercedes report when they tried it.

The engine manufactures probably were not aware that sulphur would be taken out of fuels when they designed engines commonly found on boats.

Do you add biocide glupe to your engine Twister. No doubt the fuel manufactures thought about this as well?

Not unless there's an infection to be treated.

I,ve been doing it for years.Started doing it as I have a steel boat and the fuel tank is steel and thought it would stop fuel tank going rusty.Found engine seem to run better,now we,ve got low sulphur fuel will definately carry on to lubricate pumps etc.Use 1 lt to 200lts fuel approx.cannot see how it would knacker an engine.

I said as much in the previous thread and was told I obviously didn't know anything.

Time is the judge.

Really don’t know but I changed the engine oil from basic mineral oil to Castrol GTX Magnetec diesel at the same time I put in the 2 stroke oil and the engine started to smoke also was tricky to start and started to blow back through the camshaft cover. Ended up discovering that I was loosing compression in no 4 cylinder so ended up with a complete rebuild.

When I stripped the engine I found no mechanical damage to rings etc so could be that running the engine on thinner oil GTX and the 2 stroke cleaned up the gunge on the rings and left me with a smoky leaky engine.

The argument for using in the 2 stroke was compelling and there were lots of reports of injection pumps failing due to low sulphur.
