[QUOTE=
So it gives the higher cetane number which is good (as mentioned before) but from what 5cylinders says it could be damaging the DPFs. Ah well just have to hope the DPF doesn't throw its legs in the air and give up regardless what fuel pump I use. I am now more confused than ever so better go and wash the car - it is Sunday after all!!![/QUOTE] LOL. I've washed mine already. It's like therapy

Lubricity is a different thing than pluggung dpf's EN590 spec diesel should be sufficient lubricitywise The absent sulphur is replaced by lubricity additives and also the mixed biodieselpart is good lubricitywise The gtl diesel is used for sure in shell vpower diesel other premium diesels i dont know for sure |

My question is what diesel do I put my car so I can avoid damaging my DPF? I am happy that whatever diesel I use it will have sufficient lubricity. Do I put in supermarket diesel and take a risk that it has few additives and a low cetane number or do I put in a more expensive named brand with, I presume, a higher cetane number and of these which one will have GTL in it or will they all have GTL???

If you give it a good blast trough the gears every now and again it should reach regeneration temperature and condition. Shell uses GTL in they'r diesel. I will still be using the better fuel i can get.

I only ask if I am no where near either and that is the only option left to me. I guess it would unlikely that would be the case. |

If you Google any of these fuels you will see what they claim but what you will not see is what they add to their fuels. What I would like to see is a chart of all the fuels, premium and basic, with what additives they have and what improvements the distributors claim we, the punters, can get by using their fuels. Perhaps this already exists in Which or somewhere, I haven't looked... yet.

I have search the web and nobody appears to have done a comparison of the range of diesel fuels available. What I did find was this http://www.thesun.co.uk/sol/homepage...e-you-mad.html but it appears to mix up the results of high octane fuel (which I take as petrol) but then talks about diesel. I'll keep looking.......

To throw another spanner in the works many people swear by adding ~300mls of two stroke oil to ~70 litres of diesel.
They say it improves mpg, gives a bit more power, makes it quieter and smokes less. I assume it improves the cetane value a bit, or maybe it's just placebo. I use "ordinary" Shell when I can but when I'm in Scotland the only stuff I can get is from Tesco. I've done many tanks on both and can't say I've ever noticed a difference. I did try a few tanks of Shell V-power back to back, but on my normal daily route done at the normal times (so essentially the same traffic conditions) I found no difference whatsoever. MPG was the same to within a margin of error, no noticeable increase in power, no noticeable change to engine note or vibration. No noticeable difference to ordinary Shell but about £5 a tank more. Not a big cost unless you do a lot of miles, but why spend it if you get nothing in return?
