Super fuels or additives?

Having just purchased a 159 jtdm I'd like for my own piece of mind to run it cleaner before it gets serviced in May.

As I'm surrounded by them, I'm using standard BP diesel. So, is it worth me trying BP Ultimate, or should I run through some Injector & DPF cleaner through a tank of fuel, or both?

And after my planned service and injector / egr clean in May, will running standard diesel be fine or should I revert to one of the above for preventative measures?

Thoughts?

Millers eco max + occasional Forte dpf cleaner every now and then.

Well I'm three tanks through now - the first two with BP Ultimate, the last with Shell V Power. Each has been supplemented with the appropriate measure of Redex.

Sod all difference in MPG and in fact it may be slightly less, but its possible the engine feels smoother and its quieter on startup & when warmed.

Bizarre circumstances last night. Until now I've been watching "Trip B" and the car is doing 40-44mpg in general. Last night I couldn't be bothered whilst doing a 46 mile trip, 10 miles through busy B roads and villages then the rest on a stop start M25, with some intermittent 2-3 miles at 60mph. Averaged 47mpg. Maybe "just driving the bloody thing" works better than having one eye on the economy...

I thought there was an unwritten rule - that an Alfa had to be driven like you just stole it ??

Added half a bottle of redex to my 1.9jtdm after deleting egr, a week later feels very quick and smooth, will do this once a year from now on.

Give the map sensor a clean too, simple 5min job, mine felt smoother for it immediately. And you'll see why everyone says blank the EGR! Now the EGR is blanked you won't have to clean it again.
It's amusing people spending all this money on fuels whilst allowing your EGR to crap up you engine


Any spelling/ grammatical errors are purely there to annoy!

I've got a mondeo st TDCI as my daily and I use mineral two stroke oil. 300ml to around 50 litres of diesel. The difference it made is amazing. The engine runs smoother with less knock, less smoke, better low down performance, improved mpg and it lubricates the fuel system which diesel nowadays don't do so well due to having low sulphur. Premium fuels have an "additive package" mixed in, whereas supermarket fuel is a bit hit or miss due to the supermarkets buying in whatever is cheapest at the time and therefore can be inconsistent. Diesel has to contain a small amount of biofuel for EU emissions laws which is corrosive, plus what with the lack of sulphur I believe it's responsible for premature ware on the fuel system such as injectors, fuel pump etc combined with drivers chasing mpg figures. I've always used shell diesel with mineral two stroke oil and my mondeo loves it. It's on 140k, I've done 100k in it and believe it or not it's still on the original injectors! It's used everyday and has never missed a beat but I must admit I don't chase mpg figures and I'll always redline it when joining the motorway/fast traffic. If you want to use two stroke oil it's got to be mineral based and not synthetic. Hope this will help.

Thought id give the 2 stroke a go, but on my Vivaro 1.9 Turbo diesel first.
Brimmed tank and added 350ml + some Miller eco max.
1 week on, no difference in sound, not enough noticeable difference in drivability so won't be adding any to the Jtdm.
Low soot/ ash cheap mineral used.

I must point out not every Diesel engine will gain performance with two stroke. But what is garenteed is that the fuel system is properly lubricated and will prolong the life of injectors, pump etc.

These additives are recommended by Autolusso, for good reason it seems.

Not sure how often they are supposed to be added to diesels but I pour in half a bottle every month

Sorry mate, you're getting muddled up with the German crowd.
They seem to drive irresponsibly.
