Could run the vehicle on Lubro Moly Diesel Purge straight 2 cans and your car will run like new. I did this on all my TDI"s and they've all run 500,000 + km( on original injectors).

 

is this poured in the tank with diesel or through a special process whereby you have to remove fuel lines....?
i guess injector cleaning by removal is specifically for injectors whereas additives assist in cleaning the entire system

 

The use of Techron and Sea Foam Works great for me or if I want I have a fuel system cleaning kit which I don't really use that often,Marty

 

I looked this up and found this on Caltex website....unless you are referring to a different product Depiry

RECOMMENDED FOR

Use in all four stroke petrol and light duty indirect injection diesel engine vehicles. Any vehicle with one of the symptomatic driveability problems such as hard starting, rough running, sluggish acceleration, surging, irregular automatic transmission shifts, reduced fuel economy or increased exhaust emissions could benefit by use of Techron 5000.

 

just to clarify are we talking the v6 tdi or v10?

 

guess it applies to all TDI's....

 

For a one off use you could try wynns spitfire its a fuel additive that cleans injectors I have used wynns EDT for years it gives fuel lubrication in low sulpher fuels cleans injectors and removes water from diesel it has a whole lot of claims but i have found it works well but can be hard to get. You only need 1 Litre/2000 Litres of diesel

Regular use of Stanadyne,Power Service ,Howes,assures clean injectors,lines,tanks etc, the winter versions have anti gel additives for low temp operation,and some have lubricity additive for all of the low sulphur fuels, Marty

 

So no one pulled out their injectors for a cleanup?
Appears additives is the popular, easier method...

 

I had a 2000 Mdl 3Ltr patrol and ran edt in it to 145000 Kms and never had the injectors removed unless they are giving problems i wouldnt touch them

I'd agree to not pull the injectors unless you had a reason to suspect them at fault. Clean fuel filters and clean fuel, with some form of cleaner has been my way for all my TDI's;so far, so good. I tend to use the same Caltex Vortex premium diesel and only a handful of fuel retail outlets. You get a bad dose of fuel with water or gunk from a tank and you're up sh!t creek any way you look at it.

 

I still regularly use the Lucas additive product that Graham recommended on here some time back. Been putting it into both the vehicles and not looked back. Seems to do the trick and I really notice the difference if I forget to use it at least once a month. Loose a few Km/L range and just not quite as responsive.

 

I've been using a few cleaner brands over the past 4 years and the Lucas diesel cleaner I'm happy with. But, I'm a bit anal about my fuel and only use the one brand, from limited local pumps that I'm happy with.

 

Or just run some biodiesel (up to 5% BD) every now and then. The methanol component gives it improved solvency over petrodiesel.

 

Lucas seems to be good product

 

I used to use Lucas every tank now I only use it every 3rd or 4th tank
