Vegetable Oil as an Emergency Fuel?

[J_dude]

Did you only read that far into my post? I addressed that immediately after the part you quoted. Although not ideal, there is absolutely no reason to think a CR would fail suddenly from clean vegetable oil heavily diluted in diesel fuel during a short drive in emergency conditions.

Indeed I did. I guess the second part of my comment was more about the engine oil idea. I'll admit it wasnt exactly obvious. Lol

Although generally not advised long term, there are even a few cases of people successfully running high mileages in modern Bosch CR engines on waste vegetable oil.

And there's also cases of people trying B100 (which stands a better chance of success than WVO) and barely going any distance before alerts triggered and things began messing up. CR engines have much higher temps at the injector, and running an inappropriate fuel will immediately begin having issues. How far one can go before they are messed up beyond repair, I can't say. But damage was found with very low mileage with the B100 attempts. WVO would have issues even faster. And that Elsbett system would be completely illegal in the US.

If you read the fine print "The modification kit is not suitable for an engine with an original FAP / DPF system" - so actually not engineered for the OP's vehicle.

What they are saying in a "diplomatic" way is that to modify the engine for SVO/WVO you would need to delete the DPF. Again, I'm not suggesting anyone get that kit or delete a DPF, just linking it for illustrative purposes.

And there's also cases of people trying B100 (which stands a better chance of success than WVO) and barely going any distance before alerts triggered and things began messing up

I wouldn't assume that, B100 and SVO are totally different things. I'm pretty skeptical of peoples "problems" with B100 because most B100 (even commercial) is pretty bad and has tons of particles, water, and methanol in it. I could see a modern CR engine almost immediately throwing codes on a different fuel because the NOx sensors aren't picking up expected values, etc. but that still doesn't mean you will be stranded or have permanent mechanical damage.

There are plenty of people out there with tons of miles on B100 in common rail diesel trucks that have all the same BOSCH components as the CR TDIs.

True, but that's not the same as the OP was proposing. RD meets all the specs of dino diesel, so it's a drop in replacement. Most people probably don't even realize RD has any biostock in it.

That's true. I'm familiar with Neste's renewable diesel which they claim is chemically the same as fossil diesel. There's no biodiesel in it, but it is rated R99 because of the 1% fossil diesel they have to include for a tax credit.

"Yeah, just diesel makes more sense but it’s easier to get a quart of vegetable oil in a small size. The cars getting old and I’d like to be able to tell if I have an exhaust leak in the cabin or if my diesel can’s venting pressure."

3 sizes of locking jerry cans here: https://www.cascadegerman.com/?s=je...tes=1&tags=1&sku=1&orderby=title-DESC&ixwps=1 I carry the smallest one filled with renewable diesel in my trunk. No venting.

the real solution is to dismount your tires and pyrolyze them into diesel fuel
bare rims are good enough for the amish

It's like moonshine for vehicles.

I wonder how long it takes to bake that batch of tires. Reason being how many batches could be done in a day?

In the UK, Veg oil is now way more expensive than Diesel per litre. So I keep a 5ltr bottle of Diesel in the boot.
However, when it used to be cheaper (suspect UK Government put fuel duty on Veg oil to make sure they didn't miss any tax) I would mix no more than 1/3rd veg to regular diesel. If I got close to 50/50, then I could feel the performance difference. Also, I wouldn't put veg oil in the tank during colder months, as it could 'gel' up. No smell if you use shop bought veg oil.
Never made my own Veg Diesel, too much trouble for me.

Veg oil costs more because it is planted and cultivated and processed. Diesel is sucked out of a hole in the ground and refined. Politics and economics influence the prices of both. Doubtful they'd hide a fuel tax in veg oil. Hardly anyone burns oil like that, and if its use were viable industry-wide, the demand would drive the price up faster than a tax would.

Good point. I get what you mean.
It was a observation really. Back in the day, we would have to declare to the government how much veg-oil we had used, whether we bought it or made it, and pay the fuel duty (tax) on it.
Veg oil used to be 50p/litre. Diesel £1.20/ltr
Then Gov said you didn't have to declare what veg oil you used any more, and veg oil went up in price to more than diesel/ltr....
Just an observation, and interesting coincidence...

Quick google.
Hydronated Vegitable Oil - does carry a fuel duty on it - Although I think it needs to be marked as use for fuel. not supermarket cooking oil.

Somewhere on youtube there's a tv segment of a UK guy running dyed diesel through a big cat litter filter in his garage, resulting in clear untaxed fuel. Raise taxes high enough, the market (the people) will find a way around it.

They never discussed, but i always wondered, how much dye the cat litter can absorb before it needs replacing. I don't imagine a gypsy operation like that disposed of it in an eco-friendly manner.

I’d imagine the litter would soak up quite a bit of the diesel as well, it’ll soak up oil easily. Cat litter is also pretty expensive now, I can’t imagine the process ending up cheaper than using regular diesel unless you get emotional value out of giving the government less money.

Why not just leave it out in opaque/transparent containers and let the UV turn it clear again? Lots cheaper than cat litter.
(Never tried this myself, but I’ve heard it works)

It does turn normal colored, but still shows up with a black light. Also, no amount of oil or other diesel compatible fluids that I could find would delute or get rid of the brightness of the dye under blacklight. It was a fun learning project.

100% not surprised. Anything to make things harder on people. I feel bad for most people in most European countries.

Ohh interesting, that would make sense.
Good to know! Now I have yet another reason to not bother trying illegal things lol.

Ya, and the color doesnt matter because the dip is a chemical test for the dye to my knowledge. Maybe there's different ways of doing it depending on area of the country, but...yea. Only thing I haven't been able to learn yet is what the test strips look like.

and with sales tax (percentage of sales price) on red being nearly as much as road tax (cents per gallon), the savings really ain't much at all anyways

Guess I haven't looked in a while. Few years back it was a decent difference when I price'd it out. When deciding whether or not it was worth it to load up the barrels or just use road fuel in the implements.
