Need advise on diesel additives
Discussion
lol)I use Shell, it is near to me and quite cheap. But these last two tanks I have used BP Ultimate. That makes a huge difference to my car (BMW 335, so 6 cylinders). But it is dearer, so it will be an occasional 2 tankful treat. BP Ultimate has the same declared cetane value as the others, but tests show it is higher. I understand it also improves the injector spray pattern, so reducing any compression-ignition knock/tick.
I worked in vehicle engineering at a major manufacturer, and our fuel chemist said Shell were the best fuels in her lab experience.
Manufacturers don't usually recommend additives. BMW don't recommend them, and the fuel cap says 'No additives. No bio-diesel (max B7).;

Would you have a link to that?
Shell and BP are both options locally so it would be interesting to know if there are empirical differences that might make alternating tankfuls a useful strategy.
I use Asda diesel in my daily and cant say I have ever had any issues really, we don`t have any garages around us that sell premium stuff.
I stick a shot of millers fuel treatment in once a month, probably does very little but makes me feel better.
Oil changes every 5000 miles ish for me which is roughly every 8 months, oil bought in bulk 20L drums so every change works out at roughly £25.

Hydra seemed to have a tangible effect on the crv. I'm usually quite skeptical, but I saw less smoke and a good 3-4mpg bump..

This is years old, make of it what you will. https://www.seatcupra.net/forums/threads/millers-d...
For what its worth i've been putting a couple hundred ml of cheap mineral 2T oil in with every fill up for probably 30 years now, Millers too, plus regular oil changes half or less mileage than recommended, sum total of engine and fuelling issues nil.
I should add, none of our Diesels had a DPF (bar one short owned HDi)
edit to remove invalid comment, misread the OP, different engine.
