Is Premium diesel worth it?

[Langtoftlad]

If you've just had a remap, I'd be tempted to use the fuel you've always used for a bit, just so you can see if the remap has the benefits you hoped for.

But it doesn't tell you anything meaningful, just uses sales BS

yep, I filled up just before the remap, literally 15 mins before

I though I read that it makes for a cleaner engine, inlet valves, injectors etc and that being the case its less likely to soot up the DPF, thats good enough for me. I don't expect then too give away the complete technical knowledge its obviously trade sensitive information.

Sadly my nearest costco is 20 miles away :-(

Even more sadly for me, the nearest one to me is 138.4 miles away (I have just looked it up)

They all claim that - the USP seems to be some tech borrowed from a cosmetic add

I've used almost a litre of this stuff since I had dpf issues almost a year ago.

Not had any issues since but that could be the ECU update to deal with the dpf not cleaning itself....

Must get it remapped again. Made it much nicer to drive.

I don't believe premium diesel has any effect on keeping a DPF clean - injector possibly/probably but not for the DPF because it's downstream after combustion has taken place.

With a Euro 6d engine now I've changed my driving habits completely and drive at a GPS 62/63 mph on a motorway which equates to about 2000 rpm. I try to maintain this for at least 30 minutes, changing down to 5th if necessary and repeat at least every 1000 miles or so. Still getting 27/28 mpg and would sooner accept the reduced mpg to ensure passive regeneration than spend extra money on premium diesel. I read elsewhere that unfortunately, driving it "like you stole it" is the best way to treat these engines if you want to avoid DPF issues.

As I said….. a product of the marketing people…….

I buy the cheapest and add redex or similar to every tank. I usually buy the additive when it’s on offer. A two shot bottles was £2 at Asda recently.

Yes I read that to although can't remember where. If the engine is burning cleaner as is the case, do you not think the less rubbish coming out would mean less rubbish going through the DPF and therefore resulting on less clogging as there is less for it to filter out?

My wife's face cream doesn't claim to clean her valves or make her burn cleaner or keep her unclogged.

I once filled up to the brim with Shell's premium and was mightily pi££ed off with myself when I realised during filling.
The guy in the kiosk reassured me that it would be better and I thought he's just doing his sales piece but to be fair on him, my car ran a lot smoother and I got better mpg without changing my style of driving.
I mentioned it to my garage mechanic and he told me that it's best to full up with the decent stuff every now and then if you normally use supermarket fuel.
I rarely do this but do use Redex every now and then and that does make a noticeable difference to my mpg.
Sorry I can't comment on effects after a remap as I opted not to get mine done.

The concerning thing about these additives that "remove carbon buildup" is where does it go, it must surely end up in your dpf ?
