Does anyone use Premium Diesel in the car?
Discussion
I think 5th Gear did a test a while ago...and Shell V Power seem to give an increase in fuel economy...something like 10% gain for a 5% price differential....
I noticed in my VW Polo that I average around 58 with Shell V Power and around 53 or 54 with normal Shell unleaded...
It's only a 1.2 so no noticeable difference in performance :-)

So let's say you average £0.12 pence per mile in usual derv then this magic derv could add 10% mpg for 5% cost. I noticed in my VW Polo that I average around 58 with Shell V Power and around 53 or 54 with normal Shell unleaded...

New cost £0.13
Mpg improvement let's say you got 40mpg you now get 44mpg.
I had a 123d with the N47 engine for over 6 years and it got the cheapest diseasal I could find!
Got past 80K miles and sold it before the dreaded cam-chain issues afflicted it (which was before BMW admitted any issue on their part).
No need for tractor fuel anymore!
Happy petrol days for me!

Sorry Beef but again your post makes no sense.
Anyway, he's talking about a petrol car.

Put more BP Ultimate in today, not sure it's really doing anything but can't do any harm. MPG is still pretty rubbish from my M47N2.
Cant say i'd be blindly paying 10-12p more for BP ultimate diesel without knowing if the benefits are worth it, particularly when you can buy a millers additive that works out at a penny a litre.

Sorry to sink some peoples boats...... Diesel comes from the SAME refineries here in the UK, ALL the different tankers fill from the SAME tanks, go figure.
Just an additive here and there put in for say Shell fuels that is it.
Yes but its the additive packages that make the difference same as engine oils Just an additive here and there put in for say Shell fuels that is it.
not excluding decent base stocks though Personally the only car I've had where I've felt I've noticed a benefit from premium fuel was my E46 M3 which seemed to quite like Tesco 99 or V-Power. However, my E92 335i didn't seem to run any better - or be any more economical - on premium fuel and I've not noticed my 335d being any better on things like Ultimate diesel as opposed to standard grade or even supermarket fuel. Those in the know seem to say there are only a very limited number of refineries producing fuel and that in reality most of it is pretty much the same stuff badged differently; if so that would tend to suggest that a lot of the improvements owners claim are indeed more likely to be placebo effect than anything else....

My 335i was down nearly 40bhp on 95 ron. Rolling road proved it.
Took 3 tankfuls though to get it back to full power again.

It's not a huge amount, and if it's doing any sort of cleaning it's probably worth it, only really doing it because I've done about 2k in the last 10 days and just thought why not run a couple tanks through, rather than the odd one here and there.I'll look in to an additive or even 2 stroke oil because it's pretty rough on idle but I know 2/4 of my glow plugs are dead too.
Shell V power diesel is GTL based rather than dinosaur based, Daimler Chrysler did some testing of GTL diesel 10 years ago on a Euro 3 engine here -

Summarry - it's very good for soot and emissions, and good for power
Not sure which other diesels are GTL based.

Which is a slightly different proposition to the "Does it make any difference in day to day driving and/or does it reduce fuel costs?' - I think most people would expect to a see a BHP improvement in a petrol with a knock sensor when fed on higher octane fuel
It was purely in response to him saying that even with his 335i he could notice no difference using premium petrol, I find it really surprising as when my wife filled up with 95ron and didn't tell me I thought there was something wrong with my 335i. I took it in to be looked at, they found no issue, so I then took it to someone with a rolling road, it was some 40hp down on my standard results. It only dawned on me that it might be because of the fuel as I was driving back and noticed it was almost full, where as I knew there was only 1/3 tank when I had last driven it.
If you can't notice 40hp difference with super vs standard petrol in a 335i then you won't notice any difference by using a better diesel.
