Maybe a tip for someone that doesn`t know .My Compass Avantgarde diesel engine was lacking power ,not pulling as it did when climbing hills. So I took it to my local diesel engine tuner ,AH he said you`ve been filling up at the supermarket every time .Out of the 4 injectors 2 were completely blocked ,and 1 was partly blocked. I was advised every second fill up to use shell v power or shell regular diesel . After fitting new injectors I`m getting more miles per gallon, and it goes like a bomb. Having trouble holding it back. .LOL..
 
All pump diesel should conform to EN590 ..... it will now contain 8% bio fuel , no matter where you buy it from in the UK .
Regular use of a fuel additive is probably a good idea but the " Italian Tune Up " is cheaper and will do your engine no harm , basically drive it like you stole it every now and then , make the engine work in the upper rev range and pull hard ....many modern diesel engine problems are caused by gentle driving .
VVT turbos get soot on vanes so won't go to "full send " when you give the engine a bit of work....this is seen by the ECU as it has asked for full deflection and the boost and power output confirm it hasn't got it.....so it turns that annoying engine check light on . One of the many issues that a gently driven by the vicar or vicars wife vehicles suffer from that the delivery van that flys past you in the outside lane of the motorway never will .
Diesels like hard work ...they thrive on it .
 
Correct, my new to me proton car had 27 thu miles and was from a 80 year old go to church and shops driver, it would not go over 45mph, then with redex new plugs and oil change plus three runs down the glenshane pass it now does 90mph, moden engines both petrol and derv require a good hammering, in fact it was always that way even on older engines as it lets the detergents clean the insides of your donkey.

Some vehicles have additional inline fuel filters they can cause problems if not aware of them and excessive costs with changing and renewing parts not actually needed

just checked on amazon who sell it ,its the same price as forte which I used years ago on my previous van ..I`ll give bg244 a try.

Forte used to be good, used by the trade....until it was taken over by Wynns who decided it should be changed to their inferior formulation.
Apparently people involved with the original company got together and started up Tec4 products made to the original Forte formulation. It's available on Ebay and Amazon

I was always told to avoid buying that 'driven by an old lady' car and every now and again give it a damn good thrashing! IOW traet it like grans NOT in the car/van and pretend your Lewis Hamilton every now and again. If nothing else it makes you feel 17 again!! YeeeeeeeeeHa!!

dos your have a tail,----- to tell, keep going hope your safe. ok pj. we are ok.
 
I mix some cooking oil to my fuel which cleans the fuel lines as good as any formulation, some mix 1.5 ltrs of it to 20 ltrs of heating oil, or so i hear. ;)

I suspect, like me, you don't often accelerate quickly. Before the introduction of the modern "online" MOT, my diesel car nearly failed its test. Luckily the garage owner is a friend and he tipped in some injector cleaner and told me to take it for a run and, in his words "thrash it". It then passed - easily. But he told me that if you do drive moderately you should open the injectors up fully now and again. I do this, occasionally when going up a steep long hill. I don't know if modern injectors work on a different principle?

Modern ones shut down on freewheel/coasting, a cleaner and a hard fast run sorts them out and all the exhaust tecy stuff, mercs suffer worst from what im told and a filter is over a grand.

Injectors mechanical or electronic all operate on the volume of fuel delivered not how far they open but in a mechanical system the injector may be forced open further by the pressure and volume of fuel delivered by a fuel injection pump at full throttle . These only open once per compression stroke
Modern common rail injectors can open 5 times or more during a compression stroke giving a much cleaner burn and even a post burn injection....the timing of this is also almost infinitely variable . The ECU can react incredibly quickly to torque and power requests from either the driver or transmission.
Cars and vans are not really at the cutting edge of this tech , HGV's and Plant and Agricultural vehicles are often far more capable and reliable with tractors able to have an implement like a baler take control of the engine and gearbox to ensure max output .
 
I use liquid molly once a month in the diesel works wonders for injectors
I also use vinegar mixed in water for radiator after being told it prolongs life of thermostat and cleans rust inside engine
