Thanks Dave.
Any thoughts on the choice of fuel used for the first few fill ups?

BP Ultimate is supposed to be the best diesel fuel with Shell a close second.

For 'best', insert 'most expensive'.
As things stand, we are yet to see any credible scientific evidence to back up the standard diesel fuel advice offered on this site.

I agree. And its equally true about "optimax" type petrol as well.
Loads of comment, but no evidence, that either is anything other than significantly more expensive than the alternative.
And as for the subjective claims about performance, economy or smoothness - Heisenburg principle anybody ?
Ditto supermarket petrol/diesel versus the expensive stuff.
|
Thanks for the input.
Whether it is subjective or not, the question is still there as to whether to treat the car to posh juice to start with or treat it mean from day one with normal BP stuff (I like my Nectar points!)?
|
I felt that Shell Diesel Extra (available nearly everywhere, 84p in Leeds) made a huge difference to the running of my Xsara 1.9TD. Quieter, smoother, and more willing.
Mind you, a friend bought a new Peugeut 306 HDi a couple of years ago and the dealer told him not to bother running it in at all, and to treat it like a petrol when he drove it.
|
My Mondeo TDCi runs marginally better on BP Ultimate, Shell or Texaco than other brands. The point about premium fuels though is not just the perception as to how the car drives, it is also the lubricity of the fuel, vital on a diesel engine, on this point supermarket fuels are apparently deficient.
With regard to petrol my Vectra V6 was both crisper and up to 10% more economical on Shell Optimax than even normal 95ron Shell thus making it no more expensive to run on Optimax.

The lubricity additive for diesel is added at the refinery. Other additives are added at the point of delivery. It is these additives that distinguish the brand.

So you say the advice given by Honestjohn is wrong.
I agree with HJ, over the years several of my cars seem to run better on Shell/BP etc. Also the Shell diesel at my nearest station is the same price as the supermarkets, 84.9p last time I went past.

To help you follow the conversation these two comments would be the basis;

In case you still haven't got it, the point was about absence of evidence.

Sorry Mi Lud, I think I am getting it.
Who is this chap "Heisenburg", I have never heard of him.
A good program for TV, "Judge Mark (RLBS) of the Bailey"
|
basically it states that the mere act of measuring something causes it to change.
|
Almost, but not quite. Heisenbergs Uncertainty Principle = it is impossible to determine simultaneously with equal and unlimited precision certain pairs of variables associated with the motion of a particle, eg velocity and momentum.
So measuring something like mass of a particle increasingly accurately means that we know less and less about the velocity of the particle.

Since the usual backroom pedants seem to be neglecting their duties, I should point out that the man's name was actually "Heisenberg".
Big cheese in the German nuclear fission program (which is nothing to do with atomic-powered trawlers).

I've looked old Heisenberg up on Google, Max Planke and all sorts of fastenating facts.
If anyone suffers from insomnia, epecially after a hard drive, look him up and read. You will soon drop off.

Read HJ's advice on running in a diesel, its good enough. I was slightly more aggressive in my running in schedule, and I have to say it has produced the goods. 36k miles, uses no oil, gets near the manufacturers mileage claims, and performs and feels perky.
BP ulitmate? nice stuff, does feel miles better in use, but not enough to justify the cost.
I dump some millars in the tank, give it a thrash in the 500 miles prior to the service in the assumption it will clean out crud and suspend it in the oil which then gets changed. Dunno if it works but it sounds sensible and makes me feel happy!

taking HJ's faq 4 further " make sure you continue to hit 4,500rpm through the gears several times a week. The benefit of this is it helps to self clean the injectors, it blows any accumulated soot out of the exhaust system and it helps to free off the piston rings, making the engine more efficient and less likely to use engine oil."-how do I hit the 4500rpm mark, in the bmw 530d automatic, by the time it has reached 2500rpm it is already cruising at 80mph
any thoughts?

Use the gear shift to hold gears as you accelerate.
|
thanks
do you mean shifting it to the 'S' mode from the auto mode and driving in low gear
|
Wow, I thought company car drivers didn't give a deleted
Are you taxed on nectar points for company mileage?

Working for a relatively small company it is in my interests to keep the cost of running the car down to a minimum.
We try and save money wherever possible, cheap flights rather than the normal ones, etc. We have always bought nearly new cars as well, only breaking that rule for the Volvo because of an exceptional deal.
I would resent paying extra (in the region of 10%+!)for a premium fuel if it is not giving us 10%+ better value in other areas. Not nessesarily speed, as I try to avoid the fines / points anyway.
An atmosphere of keeping costs down where possible is good for business and also means when we have had a good year we stand a better chance of a more generous bonus. What goes arround comes arround......
No, we are not charged tax on Nectar points.
(Yet). Mind you, it's budget day today so you never know...........:0)

Not sure sure but don't all 5s have Selectronic?
Push gear lever sideways and pull back or push forward to select gear. Leave it in this mode (after manually selecting gear) and entering and exiting roundabouts is quite fun.
