This stuff was recommended to me by a fitter as a low cost alternative to decoking a sluggish engine. Is this right? I have surfed previous discussion threads and found mixed views on oil additives - but what about fuel additives?

If the engine is really sluggish then fill your diesel filter full of the additive rather than diesel, and put a similar amount into the tank. The additive will allow the engine to work, and the concentration will be the best chance of cleaning the crud.
A diesel does not like being run at low revs for a long time, and is best when under load. I have used the wynns in a car engine, but the best thing for them is to be used at high revs for a couple of hours!

Diesels are self de-coking. A good hard thrash at 75-80% throttle on load will put most non- mechanical ailments to rights, assuming the engine has been serviced properly - i.e regular oil changes and injector nozzles not worn. Oil additives sometimes help a little, are always expensive, and do no more good than making the engine work hard for a half an hour.

No additive will ever sort out a worn engine, although it might give very a short term improvement.

A badly negelected engine may benefit from flushing additives just before an oil change, and some forumites will swear that Soltron does marvels to keep injectors and filters clean. I have just finished a £30 bottle of Soltron in 3 engines on the recommendation of this forum, and found it has made no detectable difference. Measured smoke remains the same at MOT as last year, and the engines start and run no better or worse than before. QED: waste of £30!

i have a new ( 180 hrs) engine i installed 2 yrs ago.
i used Soltron prior to last bunkering, it has stopped any "crud" on the transom + when @ full throttle almost no smoke ( unburnt fuel)
i think it works was scepticial @ spending £28 but possibly worth it

has also stopped the possibility of you getting any fuel contamination too.

Have test results from Mercedes to prove that after 38k miles the emissions from the Merc were lower than factory spec on the one that used soltron and past factory spec on the one that didnt.

Soltron added to the one that hadnt and brought it down to factory spec after a few days but not as low as the other one.

Had injectors disected and they were smoother than the others with less pitting and scoring.

Half fill the filter, rather than burn the additive neat.

Most MOT stations will combine this sort of treatment with a good thrashing to get a marginal engine through the MOT.

Not sure if there is much to choose between the main brands ie Forte, Wynns, Redex etc. etc. They all work on the basis of extra detergents, lubricants, solvents to cut through the crap.

My MOT man's a straight from the bottle type. And he insists Forte's a single malt among additives. It's certainly dear enough.

These things can definitely make a difference if the injector nozzles are very grotty. If the engine's smoky or knocking, it's so cheap and quick to fire some through that it's worth a go, but I'm sceptical as to whether regular use, diluted in the tank, serves much of a purpose.
