Cranfield Posted March 5, 2016 Report Share Posted March 5, 2016 and if so, are they all the same, or is there some better than others ? Following my cylinder head replacement and the other ancillary works, I seem to have one cylinder slightly missing. Its mainly evident on idling and disappears when the vehicle is being driven. I am assuming (hoping) its just some muck in the injector and am considering Injector Cleaners. Quote Link to comment Share on other sites More sharing options...
rovercoupe Posted March 5, 2016 Report Share Posted March 5, 2016 I have used redex on well carboned up pistons, left it on neat and cleaned them up a treat. Ran it through bunged up carbs on a few saws and seemed to make them run better too. Quote Link to comment Share on other sites More sharing options...
Gordon R Posted March 5, 2016 Report Share Posted March 5, 2016 One of my sons is in the trade. A rep called at their place, trying to sell some Wurth products. They didn't stock cars old enough to warrant the products, but he offered a free sample nonetheless. My lad was running a Fiat Grand Punto Sporting diesel. Quite nippy, but only did short journeys. Applied the stuff as per detailed instructions - drove a mile up the road - it threw out mega smoke. Smoke then cleared - engine ran like a sewing machine. I can't remember the name, but Google "Wurth". It was expensive to buy, but worked. Quote Link to comment Share on other sites More sharing options...

TR1 Posted March 6, 2016 Report Share Posted March 6, 2016 Forte diesel treatment is used and recommended by lots of garages. Very useful just prior to MOT can even be added direct to fuel filter for max dosage Quote Link to comment Share on other sites More sharing options...
al4x Posted March 6, 2016 Report Share Posted March 6, 2016 Try cleaner but on a newly rebuilt engine that didn't have the problem before you may want to take it back sooner rather than later Quote Link to comment Share on other sites More sharing options...
Cannon Posted March 6, 2016 Report Share Posted March 6, 2016 Liqui Moly diesel purge ran on a closed loop through the fuel pump and injectors is hard to beat. Quote Link to comment Share on other sites More sharing options...
subsonicnat Posted March 6, 2016 Report Share Posted March 6, 2016 Seen it all in that direction,Best thing you can do just before an MOT Test. Cleans the Cat as well, Wel worth putting in IMO.. Quote Link to comment Share on other sites More sharing options...
Harnser Posted March 6, 2016 Report Share Posted March 6, 2016 Anybody looking fora diesel fuel additive should lookup the 2 stroke oil in diesel threads . Best additive you will get . I have beenusingit for years . Harnser Quote Link to comment Share on other sites More sharing options...
hodge911 Posted March 6, 2016 Report Share Posted March 6, 2016 I have for the last 3 vehicles [ disco 300tdi hilux surf and present xtrail] used every 3rd fill up used a concocksion [? on spelling ] of redex and 2 stroke oil . it makes the run smoother with cleaner emissions and IMHO I get slightly better fuel consumption Quote Link to comment Share on other sites More sharing options...
mossy835 Posted March 6, 2016 Report Share Posted March 6, 2016 do you just put it in the tank. Quote Link to comment Share on other sites More sharing options...
walshie Posted March 6, 2016 Report Share Posted March 6, 2016 Seems a bit coincidental that the symptoms started after you had the work done. I'd take it back and see what they have to say. It might be the beginning of something more serious. Quote Link to comment Share on other sites More sharing options...
hodge911 Posted March 6, 2016 Report Share Posted March 6, 2016 do you just put it in the tank. I use 2 measures of redex and 250ml of 2 stoke oil put them into an old 2 stoke oil bottle and give a good shake then when I get to petrol station I pour into the tank before I fill up with diesel Quote Link to comment Share on other sites More sharing options...
Glenlivet Posted March 6, 2016 Report Share Posted March 6, 2016 Found this on a website called Fuel Expert. The full test can be found here http://www.fuelexpert.co.za/2-stroke-oil-in-diesel-technical-study.php At a 200:1 volumetric blending ratio, 2-stroke oil has a negligible effect on diesel lubricity. All diesel fuel sold in South Africa has to meet the SANS 342:2014 lubricity specification to ensure the proper protection of diesel fuel pumps and injector systems. The low sulphur diesel products sold by Sasol contain lubricity improver additives which are far more effective than 2-stroke oil. At a 200:1 volumetric blending ratio, 2-stroke oil has a negligible effect on diesel cetane number. No measurable effect on all other regulated diesel properties was measured at a 200:1 dose of 2-stroke oil in diesel. 2-stroke oil can contain around 16ppm zinc, or higher depending on the formulation and batch. Trace amounts of zinc in diesel are known to rapidly accelerate injector nozzle deposits. Engine test results show that a 200:1 blend of 2-stroke oil in diesel results in a 2% loss of engine power in a 16 hour test due to injector fouling, a risk that would apply to any common rail diesel engine, but could also worsen fouling in older engines. Vehicles fitted with a diesel particulate filter (DPF) in the exhaust system could experience reduced DPF life due to the collection of ash and metal based contaminants in the filter over time with the continued use of 2-stroke oil.

TIGHTCHOKE Posted March 6, 2016 Report Share Posted March 6, 2016 REDEX or as the Services know it OM15 has been used to good effect on both Petrol and Diesel systems over the years. I use the Forte additives on recomendation from a garage. Looks like the validity of the 2 stroke use is in question. Quote Link to comment Share on other sites More sharing options...
Vince Green Posted March 6, 2016 Report Share Posted March 6, 2016 I usually throw some in the tank if I am going on a long run but its hard to say how much good it does really. It makes me feel better though. Quote Link to comment Share on other sites More sharing options...
Pistol p Posted March 6, 2016 Report Share Posted March 6, 2016 (edited) I use the millers and forte, both with good results. Generally running the best fuel, shell, esso, etc, rather than supermarket rubbish is a good start. If Frank, Ron or Enzo haven't advertised it on their cars, I don't use it.

Cranfield Posted March 7, 2016 Author Report Share Posted March 7, 2016 Seems a bit coincidental that the symptoms started after you had the work done. I'd take it back and see what they have to say. It might be the beginning of something more serious. It is missing very slightly when cold, but this disappears completely when the vehicle is moving and at idle when its warm. The injectors are the originals (23 years) and the diagnosis is that one of them may be dirty, I am trying to avoid replacing them and have been advised to try the injection cleaner first. Having always been a bit cynical about the benefits of "additives", I thought I would get some opinions. Otherwise the vehicle is running very well, no smoke, the powers returned and its very quiet.

I agree. Always start with the cheapest fix and work your way up, but if it wasn't doing this before, why would it suddenly get a dirty injector after it had been in the garage?

It had not been running that smooth for some time prior to the actual total breakdown, so now its OK, perhaps I am noticing something that has been there for a while. I really don't want to think its something more serious. Why not join me in whistling in the dark, as we see if the Tooth Fairy and Father Christmas arrive.
