What are your mpg gains then? As I am still a bit dubious.

Well, on LPG and diesel power plus I was averaging low 50s. Within 2 tanks of sport 4, my long term average in the car was up to 58+ mpg. It also for the first time read a range of over 600 miles on a fill-up (once I drove away from the garage) - Never actually got 600 yet, but 540ish miles before the beeper is now a reality. :)
 
Thats really good mate. Especially with your power. My tank takes 40 litres and will do about 450miles. So lets see what the second tank of sport 4 can do nexy week. :)

Whats your spec?
 
Hi there Gentlemen , i have found a stockist of the Millers power plus sport 4 additive for a 5ltr bottle for the fantastic price of £46 incl , and he will post it to for around the £5 mark.

I recon if someone did a bulk buy and picked it up say for 5/10 5ltr bottles they would drop there price to around £42/£44 Tel 0113-2407772.
 
I would think that if you ran with half a tank of a 100 bio diesel or maybe bio 20 first , and then changed the filter afterwards and then ran with some standard diesel plus the sports 4 it maybe more noticeable.

Fasteronline are cheaper, £49.99 incl postage IIRC.
 
be very careful of diesel addatives especially if you have a new diesel with dpf fitted the amount of damage they can cause is ££££.
not only does it damage the priming pump but also damages the actual pump itself.
if your car is under warranty and something goes on ure pumps/ injectors the fuel is normally tested now and if anything abnormal is found to which could be described as a fule enhancer youll have to pay for it.
no lies seen it before and very recently...
 
Also was thinking of having a remap on mine too, do a lot of m-way mileage. is it worth having that dun to improve mpg?
 
so this will not improve mpg as people say it will then? im totally new to TDI's so dnt know much. Also i jus tipped 5k miles. Some people have said to change the oil at this. Is it worth doing it or not?
