Diesel Quality - where would you buy for a long term runner?

Foxy-Stoat_3

Doing 25,000 miles a year in a 55+mpg diesel is far cheaper than petrol.

Buy the Golf, buy whatever fuel you like and cross your fingers.

No issues with DPF if your doing 25,000 miles a year, assuming some motorway or dual carriageway driving.

Issues with DMF means if you need a clutch in 100,000 miles then it may cost you a few hundred more, unless it fails prematurely....not sure if the 2012 year Golfs had any issues with them.

You will be getting close to 600 miles out of a tank of diesel no matter how much you pay for the diesel. Injectors or pumps may or may not fail, luck of the draw there.

I wouldn't be running a diesel at all, too much unreliable/expensive cr4p attached to them these days (eg DMF and DPF).
Fine if you want to buy new and keep for just 2-3 years, but in the long term petrol is cheaper to run.......

Yes.

totally agree. modern diesels scare the bejesus out of me. Will be getting this one serviced every 10K miles by VW and plan to parachute to safety before something painful goes wrong (or at the first sign of impending pain) - ideally at around 100,000 miles.

Is this a money saving thing ? Why not buy a car 1/4 the price with 100K on the clock, and rag it til it hits 225K ?

Yeah.. makes total sense.

However without going into a world of detail, i'm being "given" a car to run for 3-4 years, and this - or my choice of new or nearly new standard family hatchback - were the parameters involved and "just make sure its reliable"

Not a fan of the new focus, 308 possibly but didnt, didnt fancy a leon, didnt fancy a skoda.

This that about sums it up.

Its a roll of the dice really.

I really wish there were some decent objective test results specifically relating to the cleaning properties of different diesel fuels, but sadly I've never found any . I'd be interested for my own car, which has now covered 90k miles but I intend to keep it for a good few years yet. I've run it on mostly Morrisons diesel for the two and a half years I've had it. Should I start using something 'better', at least for a while to clean it a bit? I have no idea!

BP have some pictures of clean and dirty injectors (electron micrographs?) and the apparent different spray patterns on their BP Ultimate pages here, but that's marketing that proves nothing. They also make claims relating to their regular fuels.

Shell now say very little at all about their Fuelsave Diesel on their website, and barely any more about Shell V-Power Nitro+ Diesel. (What an irritating name by the way. I hate it when products are marketed to men as if we're all still 10 year old boys...)

One point that often gets made is that all Diesel sold in the UK is required to meet the EN590 standard. Does this standard include any measure of how much a fuel will leave residue that could block injectors, or any cleaning properties? I'm guessing not, but it would be interesting to know.

I personally would much prefer Shell or BP over any supermarket fuel and for a penny I would take the branded stuff, but I am a price tart at the end of the day.

Honestjohn does not think too highly of supermarket fuels.

EN590 has (amongst others) specifications for maximum carbon residue, maximum ash,water content and lubricity - which covers most of the problems that supermarket fuels are commonly accused of .

I'd spotted the carbon residue and ash content parts of the standard, but I wasn't sure they related to the residue left in an engine after combustion, do they?

You know my thoughts on Golf's already Paul I'm sure.

I think for a reliable 1.6 diesel there is little too beat the Hyundai I30/Kia Cee'd, Hyundai diesels seem to be pretty bomb proof (and they have 5/7 year warranties just in case).
