WOW,
remind me NOT to ask any questions either!
Hi pbhawkin,
You are correct, it does make me cross when people on this site seem to be very agressive when questions are asked which are not to their liking.
Not sure why it happens on this forum, I am a member of a few and none have this core element of angry people. I guess it is the macho bit in us driving big trucks around!
Some of us, like me keep our postings down, because it is just not worth being attacked! I for example seemed to have got it in the neck for not noticing a thread that was put on earlier this year and I repeated it!
Anyway, back to the topic!
Great information coming on the fuel which is still amazing, keep it coming 10forcash!
Regards
Chris

Cetane is effectively a measure of ignition delay (higher numbers = shorter delay).
The predominant impact of this is that you get a more controlled (smoother) burn on high cetane fuel than low cetane fuel.
Is Shell is using GTL (gas-to-liquids) blendstock in their diesel in the UK it may very well make a difference. I worked in Qatar for 3 years negotiating on behalf of the Qatar gov't their GTL projects. Shell's US$9 billion plant isn't yet complete, so they are probably hauling the stuff from Bintulu, Malaysia (which may account for part of the extra cost). The diesel GTL is made from natural gas. Pure GTL diesel is clear, nas no odour, absolutely no Sulphur compounds and no aromatic hydrocarbons. The latter 2 points may cause problems in old vehicles (seals leaking, cruddy nozzles plugging) but in a new-ish vehicle this stuff is great. Shell and the other oil companies tested it by just filling a new diesel vehicle with 100%GTL diesel and they ran just find and had no smoke (couldn't make it smoke when they tried) and definitely results in much cleaner engines. It also doesn't make hands or shoes stink when drips happen when filling. The lack of aromatic hydrocarbons makes GTL diesel less dense as a fuel - it falls just below most international specifications on density (so you get more energy per KG of fuel but less per litre). With all the regulatory constraints they blend the stuff with oil diesel. Once the plants in Qatar come on line (about 2010) expect to see a lot of near-clear diesel fuel. Just remember someone has to pay off the US$9 billion cost of the GTL plants Jim Dowell - D4 HSE TDi, 12,000 hydraulic winch & hidden winch mount, MTRs, TyreDog, Traxide 2 x aux battery system, fixed air compressor, Dolium roof rack, MitchHitch.

the GTL diesel compare in viscosity terms (about 28 secs)......just curious
I seem to recall there was a plant doing this in New Zealand doing this in the 70's (Kapuni ?) only the liquid yielded was "feedstock"...BREXIT - done properly.

US$9 billion, that's nothing!!! We'll be paying that for a few folks getting sweaty in 2012 for a week. To spend it on a GTL plant seems much more sensible!

Hi Buzz,
I will be filling with normal diesel during the week before a 500 mile round trip, so will be interesting to see if my slow auto take up will come back. Sadly I have no access to V Power in Devizes and will not make it much further without a re fuel.
Regards

Finding fuel in your area
I have found www.petrolprices.com useful in finding where fuel is available and for how much.
Hope it helps.V8NOT - because it's a diesel of course!

TBH, I never suspected the fuel for the sometimes slow response of the autobox...
But, as I normally use the regular Shell due to no noticeable MPG difference (in contrast to Total Excellium, that one really does help! But I've got a Shell card... ) and I have the slow response problem, I now tried the V-power one.
Result: problem gone !!!!
So, thanks for the tip and I'll try the regular next time to see if the problem comes back

I refuelled last week with normal diesel and after about 100 miles the gearbox lag appeared to be back but not as severe.
I am off to Cornwall tomorrow for a couple of days and will have to fill up at whatever pumps I can on route. I am reasonably certain that it will be normal diesel.
Will report back by weekend how the car reacts once again.

According to the November What Car, their tests showed Esso Energy diesel to out perform BP Regular and Ultimate diesel on economy and performance, albeit marginally. 0.3 secs 0-60 is not to be sniffed at though.
Esso Supreme Petrol also gave the best performance, I stick that in my Merc.

Hi Claud,
Useful information.
Well on my trip to Cornwall I filled up twice, neither was V Power. My Son drove us back and to be honest neither of us noticed much if any hesitation when pulling away.
This leads me to believe that the V Power has cleaned something out and it is still 'cleaned'!
The car is going in for a service next week so I guess any improvement will be wiped out by whatever they do.
Regards
Chris

SN - what was the outcome of your full tank ? Did you notice any difference ?
I encountered Shell V Power for the first time this week. I hesitate to believe, but I really do think there was an increase in mpg. I think the answer is to fill up with V power and note the range calculation when driving at 60 mph for 5 miles just after.
Then repeat the exercise after filling up at Morrisons...

had to fill up with tesco regular the other day. result is........lumpy gearshift...crappy acceleraton......monumental turbolag
putting it into sand mode on the crap fuel replicates the running on total excellium.....as a previous NON-BELIEVER in super fuel b ks i am now convincedGone.......but not forgotten
