HVO fuel

Came home from a few days away in the van and stopped to refuel at the cheapest station about 10 miles from home.

They have recently started selling HVO 100, which is the current version of used vegetable oil as a renewable fuel with up to 90% reduction in emissions.

Not knowing anything about it, I filled with B7 and a dose of Millers ecomax diesel additive as is my occasional practice.

Having come home, I have done a bit of research and find that it is entirely compatible with vehicles using diesel. Similar performance and economy allegedly. However I did not check the price (their B7 is £1.29 litre).

I haven't heard much chat about HVO, but a quick internet search seems to indicate I can use it in my 2014 XTrail or indeed any diesel vehicle.

The only downside I can find is that B7 contains FAME which are impurities and they potentially can build up in a tank. HVO may dislodge them and cause some issues. A tank clean seems advisable.

On the upside, you can mix the two fuels quite happily as they are apparently chemically identical and HVO does not form a gel at -12c as diesel can.

Has anyone any actual experience of HVO who might like to comment.

I didn't take note of the price, some sites say it is similar to B7. The big plus appears to be that it is better for the environment and also is a gateway to extending the life of diesel engines long past the 2035 cessation of new builds.

Or will it be taxed out of existence or not promoted in the same way that LPG conversions were not, and are still not seen as a viable alternative to the blinkered headlong rush to electric vehicles.

Some diesels dont like it one bit, a chap i knew tried it in a tranny and had to have it removed as engine died after a few miles.
My thinking was he had a dirty tank or filter.
Any older diesels will run no bother with it, mine will run on it and a few times i have also ran cooking oil mix no bother.
Simple test is try and see how it goes, a clean sys should have no problems, good idea is change the fuel filter after a few hundred miles as it may have dislodged cr-p in the tank/lines etc.
 
I get the impression that this is substantially more developed than the old chip pan oil that was popular 20 or 30 years ago.
One of the companies developing and marketing HVO is Total energie, and almost without exception the various websites I visited stated it is suitable for all diesels as a direct and immediate alternative.

Yes not straight old chippy oil but a proper new clean blend or from new crops, as i said some tanks lines may have crud in them so a filter is best kept on hand if the engine has high milage, other wise no problem, use it . (y)

Firstly, FAME is not an impurity; rather it is fatty acid methyl ester, a type of biodiesel produced by transesterification using methanol. B7 contains 7% biodiesel and 93% mineral diesel. Albeit with some modifications for some, all diesel engines can run on B100 (100% biodiesel) AFAICT. However, it has a tendency to 'liberate' sludge from fuel tanks that have been run on mineral diesel for a long time, and so fuel filter changes may be needed. Also, some seals go soft and may need to be changed to allow the system to successfully convert to 100% biodiesel. FAME production leaves glycerol as a problematic waste product. HVO (Hydrogenated vegetable oil) produced biodiesel by a different process that doesn't produce glycerol (but there are other disadvantages). Prior to the de-minimis being scrapped, I used to run a 2.8 Pajero on 25% UCO and was considering buying my own still to make FAME from used chip shop oil -- until the chip shops realised there was a market for their waste and the price shot up horribly!

Anyway, some interesting reading: https://biorrefineria.blogspot.com/...e-diesel-advantages-over-fame-properties.html
