Well bloody hell appologies to peter N .. im the one who doesnt know anything..

So all the autoexpress and technical guides over the years that have told me the second figure is the wall size are liars then? Even tyre fitters kiwk fit or any independant tyre places ask what wall.. 60, 65 etc etc.

We live and learn..

It is the wall size Paul, it's just that it's expressed as a % of the tyre width rather than an absolute number. No idea why!!

As a side question to the OP. When did you have the tuning box fitted, what sort of results are you getting, have there been any component failures, would you recommend one and which one do you have fitted?

I've run Texaco a few times and I've had poor mpg from it but that might just be local stockists.. I do also notice a difference on supermarket fuel so for the last 3k I've been on Ultimate, well my car has. I find it doesn't cost anymore with the savings on mpg. On normal fuel I get 200 miles out the first quarter of a tank but on Ultimate i get at least 250. I can drive from MK to manchester before the fuel gauge even moves from full.

My point is, fuel is the second biggest factor in MPG on mine (after right foot)
On those figures " on Ultimate i get at least 250."
You've got to try to get 200 out of the red light Chris :-D
You have got 250 miles in there driven carefully from the first time you see the red light... but 150 is easily achieveable in an Hdi at 65mph,, It just takes a bit of bravery the first time you do it (and a can in the back) :-D
All those years I spent crawling along late at night when the garage I had planned to go to was closed not realizing that I had another 100 miles in the tank!!

I'm presuming you took lots of luggage to Cornwall that you don't normally carry around with you. Surprised nobody mentioned the weight, which is one of the major factors in fuel consumption. Power to weight ratio.
