I've used anti-smoke additive very successfully on an old petrol-engined Volvo that would previously only pass the MOT emissions test on zero RPM (really!!).

But is there any reason to avoid such products for a marine diesel?

I have recently decoked my engine, but it is still rather smoky, particularly when starting. Although oil consumption is not excessive it seems some is getting past the piston rings and I am hoping to reduce emissions as for my Volvo.

The colour of the smoke will tell you if it is oil or diesel.

If it only smokes when it is cold then it is probably diesel and depending on the age of your engine there maybe nothing you can do about it!

You said oil consumption is not excessive what exactly does that mean. Some engines were designed to burn oil and even modern engines will (depending on type) do this.

If it is an old engine I feel you may get more success out of an injector refurbishment than any additive!

Anti-smoke additive is more common used than many appreciate ... there are various Public Transport company's that use it around the world !! You wouldn't believe it when behind some - but yes its true !!

We were supplying Riga for some time previously ... till we stopped ...

Been on the web site and if your story can be relied upon it would appear to be the answer, on problem though can we get in the UK. Have enquired by email. If it can stop a 1973 Ford Sabre 180 smoking I will make a fortune selling it over here.

At the show 4 years back I asked Mermaid who still do Fords what cost a full overhaul, £2000, was the reply. Will I be smoke free on start up after the job is done? No it's a design feature was the reply, still smoking, but I have stopped so I am trying to assist in the greener planet.

This basically is a truck engine with low stress and mechanical fuel injection. Cold it will always smoke as it will over fuel the engine, only when it is heated will this problem decrease.

I'll go back to my earlier post and say injector refurbishment will help out.......... but not cure the problem, which is design!

Even brand new diesels will smoke a bit specialy on tickover,its in the design of the combustion chamber and piston,dont worry about it as long as its not smoke screen smoke.

Thanks for the replies! The engine is a 1989 Perkins Prima M50 with 1900 hrs. The smoke is blue - almost certainly oil - but really not that noticeable when warmed up and under power. I guess I needn't worry about it - and just carry spare oil!
