Pence per mile

Oh, it is generally believed by various sources (scientists, industry experts, current and previous owners, fuel tracking apps, yadda yadda) considered to have some level of authority on the matter, that premium diesel in this particular engine helps keep it cleaner and may slightly increase the overall MPG. I'm sure everyone is totally wrong and forumites will start chucking loads of contradictory reports and graphs around arguing both sides, while not actually coming up with a definitive answer... as they usually do... but my car seems happier with it, so I carry on.

Sounds like placebo effect. A 2003 Passat does not need special super diesel. It isn't like super unleaded where there is a clear difference.
 
I noticed mine seemed to start cleaner if I put some 2 stroke oil in when I filled the tank.

I did try various different fuels in my 5 series when I had that. Different supermarkets diesel, different super diesels (shell, bp, esso etc). I ran 3 or 4 full tanks of each before moving onto the next fuel to try.

Granted, I was only concerned to see if there was any difference in fuel economy between them. I didn't notice any significant difference between most of them. Asda diesel providing a marginally lower mpg than the rest. So now, when filling my diesels, I almost don't care.

My edition 30 was noticibly better driving on super unleaded, so I only put that in that car. My 3.0 A4 though, doesn't seem to mind. So if I'm filling up at Tesco, I'll use momentum. Or Costco ill use premium. Otherwise, regular old unleaded.
 
Because i like spreadsheets. Mine was good, then went bad, and is now getting a bit better again!

Well it hasn't been getting as dirty inside as it used to on cheap diesel, and my Fuelio app says I'm getting slightly better mileage... so I guess that means BP/Shell, my mechanic and Sygic are all secretly in cahoots, to diddle me out of my hard-earned...?
 
Is there really a point to this?
If all you’re doing is quoting fuel consumption, then that’s data available from the manufacturers.

Surely the more interesting stat is the total cost of ownership per mile, including depreciation, road tax, insurance and maintenance.

You take your engine apart to check for dirt?

If you are going to cancel out the point of buying a diesel Passat by insisting on running it on overpriced wonder diesel you may as well have got a petrol one!

Oh yes, twice a week without fail - full strip down of the carbs and turbines, jet out with IPA, flush with RedEx and then Ad-Blue, then double-coat of engine wax and schleam, applied using a plumbus.... !! :rolleyes:

1/. It cost me nothing. It was a Christmas present.
2/. I'm more concerned with the amount of time I spend stuck in traffic, building up soot and cack in the system, than saving a couple of pence here and there by buying cheap diesel. If fuel price was that much of an issue I'd be running it on veg oil or something.
3/. If you have such an issue with my car, feel free to buy me the one you think I should be driving...! :p
 
Whats the best app for trackign mpg etc for android devices if any of you use them
Fuelio is free, works well enough and has some decent features.
Some others use Fuelly.

I have no issue with the car, I just think premium diesel in it is a waste of money :p I don't use it on mine either.
Well then I'm sorry for any offence or inconvenience my choice of fuel may have caused you...
 
I use Fuelio to track my costs. It's telling me £0.185 per mile for approaching a year and 4.5k miles in my RS Megane 265 Cup.

Not quite true. Everyone knows that manufacturer quoted statistics are inflated by some godly high percentage.

I much prefer to see people's real world running costs. Especially over 10k miles, to average out anomalies.

Fuelio tells me I'm at 8.5p/mile over 30k miles. Audi A3.
 
Tesla = 0.00p per mile, free super charging;)
Do you actually use them? I do a commute from Oxon down to London daily, i see so many teslas, they make so much sense and to be honest i could probably almost make the maths work for one if i applied some manmaths to it.

However, i do wonder if people ever actually really bother using the big bank of superchargers at Oxford en route. They are on the way but who wants to wait for the car to charge at a services? I cant imagine not just charging at home in the garage? At the 11p/kwh which i pay, the power is still almost a negligible factor in running one?
