HVO100 diesel fuel.

1.6tdi 315km

Started using it exclusively (bit of an effort to get to garage with it) since dpf

ash content is 72% and I'm hoping to avoid having to do a full clean/replacement.

So far find it runs smoother

They've treated it very much as a truck fuel rather than a car fuel - no idea why but its been a trend to some extent in Ireland where suppliers have focussed HVO promotion mostly on fleet customers. The link @mikeecho has posted is interesting in that its not tucked away in their fleet section so maybe that's changing for Circle K.

The Rathcrogue pumps are car-sized even if they're in the truck section whereas the Kill North pumps aren't available to cars without an adapter. It's possible to buy a cheap plastic converter that allows car owners to use truck-specific pumps (very popular with German HVO users) but I haven't found an Irish source for them yet.

Edit - just noticed that under the heading 'Why Make The Switch' in the Circle K link, point 3 mentions fleet:

Performance: HVO offers similar or even improved performance compared to traditional diesel, ensuring that your fleet maintains its efficiency and reliability.

Rathcrogue is handy enough and quiet in terms of trucks. There's no downside to HVO other than price and Circle K (and Inver) seem to have sorted that for the moment. It could be argued that the higher cetane rating and lower soot would be worth a few cent but price matching makes it even more compelling.

There is information about outlets selling it on the main suppliers webpages, but you will need to do your own personal list to see which ones are best located to your usual driving journey.

Myself I have most often filled up an hours drive from home as the station there is beside my clients office.

Personally did not see such a large change in fuel burning rate.

Update: found this for finding sites that have it for sale:

https://www.sustainabletourismnetwork.ie/hvo-map-ireland/

Also they do NOT have any of the Certa sites listed however… And the one listed in Coynes Cross doesn't seem to have any as I was only there last week looking for it… unless its at the "truck pimps"

Retail HVO has additives to meet EN15940. When it meets that standard, it's lubricity is as good if not better than B7.

Found the HVO pump at The Apple Green in Coynes Cross, Wicklow today.

it's at the back of the site (at Truck stop part, big honking tank of it) You pre-pay there. BUT @1.86 per/LTR …(regular D is 1.76)

…out of the few places I've been to so far, Certa have been only a few cent over Diesel price.

But..At least its available somewhere in Co Wicklow now.

That makes a lot of sense for the dpf but be careful just using it was any engine. For the VW group, they only approve those engines after mid 2021. There are documented cases of injectors blocking and because they used HVO, that was blamed. It's an easy target as it's a change and it may not be true but HVO does not have the same lubrication ability of diesel. So it was the smoking gun.

What is HVO manufactured from?

If the HVO is manufactured from cleared forestry land then it is not so wonderful, is it?

So, where does our imported HVO actually come from? According to data from Ireland’s National Oil Reserve Agency (Nora), about half of the transport biofuel entering our market in 2024 came from UCO and POME, which are mostly imported from Malaysia, Indonesia and China, regions plagued by deforestation as a result of expanding palm oil production.

Suspicion is mounting internationally about rampant fraud in these supply chains. Given lax auditing and strong financial incentives, it’s disturbingly easy and attractive to pass off virgin palm oil as a waste product.

The implications for the climate are dire. Many studies have shown how biodiesel from virgin vegetable oils cause similar greenhouse gas emissions as diesel, and in some cases, are much worse. According to one study, emissions from palm oil biodiesel are three times greater than those from fossil diesel, because of its association with tropical rainforest deforestation. Substituting fossil fuels with palm oil-derived HVO isn’t just unhelpful, it’s blatantly harmful and irresponsible.
