Diesel V super Diesel?

[ukracer]

And you havnt meantioned all that fuel you saved at 60mpg, you then pour down the exhaust on each of the exhaust strokes to get the sost glowing and then if you slow down below 40 mph it was all wasted and it has to start again!
as said I had one customer with an ashcan hehe that was spell check changing qashqai! quite apt so left it, her commute was just at the point when the regen cut in then she reached work , Literally took a few weeks and back again I cleaned it 4times with a power wash etc etc then I 'properly' cleaned it out!! hasnt missed a beat since.

Will it store a code showing its done a regen?

No it should have when it last did one on some scanners maybe

Rover SD1 Vittesse instead. Awesome car especially for an 18 yr old!

Still got mine in the back------ somewhere

I find my series 3 landy with a 2.25 diesel runs much better on bp ultimate than it dose on cheap diesel. It' quieter, there is more power etc. It is a totally stock engine. There may be a good reason for this, the premium fuels have additives which are especially benifical to older diesel engines, they contain a sulphur replacement which helps lubricate the engine properly as with diesels sulphur helps lubricate the cylinders and piston rings, it is why apart from it being cheap cargo ships out side emission control areas use high sulphur fuel as it cuts the amount of cylinder lubricating oil we have to put into the engine by up to 3/4. And it is hell expensive stuff so any saving is majorly benifical.

Last time I looked a bottle of decent injector cleaner was ( about ) 15 quid. Around here the difference between Asda and Shell is about 3p a litre - so if I were having to use a lube/cleaner from time to time there would be next to no cost difference, not enough for me to be bothered.

never used injector cleaner,hence my question earlier re if they actually work ?

I dont know. But I put a bottle through the dog van when I bought it and the injector balance statistics improved straight away, I put another bottle through a few tanks later and they improved again. They were well in spec then so I haven't bothered since. I cannot say if regular use, my use of Shell fuel or the injector cleaner or a combination of all was responsible.

Same here, that said most of the injectors on my vehicles/plant are not electronic and a new set of nozzles are only about £50. If there is a suspect injector on an engine I just change all the nozzles and pop test them on an old manual Hatridge tester ( middle of the bench below ). With the cost of the electronic ones I suppose a few bottles of cleaner is always worth a try.

I bung a Redex cleaner in the tank every couple of months, I get 3 bottles for £9-00 from the local B&M store, Cant say I have noticed any difference but no problems either considering I mainly do short journeys,
I "found" 5 gallons of Redex once, Setting off on a 400 mile trip in the good old Victor 2300 estate I gave it a really good dose into the tank, TOO good actually after about 100 miles the motor went on to 3 cyls,. One of the plugs had whiskered like two strokes used to, Quick fix and kept topping up with more petrol.

Re. DPFs, I always thought that the idea was that they trap particulates then BURN them off when hot as opposed to just dumping them out on the motorway. I.e, the trapped carbon particles being converted to CO2 rather than just popped out the back as carbon.

It is and they do, just the process is not perfect and so you can often also get some soot come out as well, hopefully this would happen away from built up areas but overall there is a massive reduction in particulate emissions overall.

Liking the kit ! thats the thing with electronic ones,just wondered if its all snake oil really,will do a leak off at some time,best give it a thrashing first though.

I buy from whoever is cheapest, comfortable in the knowledge that the diesel is all coming from Grangemouth.

remember the blockades?, Asda NE England SE scotland gets/got its Diesel from the Dutch and so had fuel during the blockade. Ive found Asda diesel goes further and the engine knocks less than Tesco stuff. I have no choice but to get supermarket fuel.

As I thought. So aside from the negative points about pernicaty driving requirements, reduced performance and fuel consumption, as an emissions control device, they do their job at reducing diesel particulates.

I know there are cars now with adblue. Does the post treatment of NOx allow for reduced (or eliminated) EGR and a resulting cleaner burn, less soot produced and an expected increase in performance/economy?

Deliberately reducing combustion temperatures to curb NOx has always struck me as a difficult trade off - high compression, temperatures and lean burn are essentially the +vs of diesels.

With an SCR (Selective Catalytic Reduction) system using Adblue there is no external EGR as the system should be capable of converting it into nitrogen and water. Engines may still use some internal EGR though (i.e. by playing with the valve timing so as to retain some exhaust gases in the cylinder). One of the big downsides with SCR systems is all the exceptions e.g. most of the systems are disabled when the ambient temperature is below 10 degrees.
