I thought so, but I definitely have a thinner oil at the top than at the bottom, I have also not had any water come out of my wvo, which I was surprised at.

It takes it's time to work down through. Give it 48 hours, see what you have then.
You might not get visible water, if the oil is pretty good stuff. Bad oil will give clear water in the bottom, sometimes.
What you will most likely see is a cup full, or so, of very dark, slightly thicker liquid.

The oil had been sitting for around a week or so in my big barrel, and I added the petrol on Wednesday evening.

I will leave it until Sunday evening and drop the bottom L or so and see what it looks like.

It had been pretty well settled before I poured it in, and my 5 and 10 micron socks haven't got a huge amount in them so I was only really expecting water off the bottom.

You don't usually get free, clear water. It's more like a watery brown sludge. If you do the tests with the jam jars, you'll see it. You'll see how it moves differently to the rest, when you swill it around in the jar. It's a job to explain it.
If it's really good oil, there will be very little of it.
I'd almost say, get some bad oil in a jam jar. The results will be that much more dramatic, and easier to see, but it will give you the idea of what to look for.

I See what you mean.

I did the hot pan test before settling and I had a fair bit of water in it. (I think? I may have done it wrong)

This oil is pretty well used as well, rather dark, I did have a bit of it in a clear jar and kept it in the sunlight to see what was in it, but it looked like clear oil to me, the small air bubbles dissapeared after a while too.

I will take another sample on Sunday and see whats what.

Dark oil will often stay dark, even when well filtered, and de watered.
When the dark oil is well filtered and dewatered, even though it's still dark, you'll be able to see quite clearly through it, if it's in a jam jar. Sort of like looking at an old sepia photo.
It'll have a crystalline like appearance about it, where as the untreated oil just looks dull and dead.

Out of really dark, but otherwise quite clean oil, after adding the petrol and settling, you should get quite a noticeable sludge at the bottom of the container.

Right, I'm with you now.

This oil is very dark, but if you catch the light is is transparent.

I have some old old waste veg oil here that is so manky its just opaque and despite the way you look at it, it never is transparent at all.

for a substantial container the plastic waste bins provided by the council are very good come in different sizes also they have wheels you might have to add a hasp and padlock for security

Quick update, my 210 300 Turbo diesel runs pretty well on my mix which is nice. Just need to change the tank strainer (preventative) and I will be happy to rely on the car permanently.

The diesel bike has been neglected a bit, have a spare set of injectors that I will swap out, just haven't had a chance to do it yet.

Had a play with the diesel bike today, swapped in my spare injectors, exactly the same behaviour. Started to long pain in the arse, messy task of adjusting the injection timing.

Result is:

engine is starts much easier on my WVO mix and sounds sweeter, still smokes at idle though.

I advanced it 3 degrees, 4.5 degrees is my limit as its achieved by removing copper shims.

Any ideas on how much advance I should be running on WVO?

How do you find the 606 compared to your tweaked 613?

I've a 613 fitted with a Brabus D6 box.
Although I've only driven it once for 250 miles a year ago, kick down

made me 'LOL'

, as people say these days.

It's the opposite of the 613, it likes to rev, there isn't as much torque, huge difference something like 120ft lbs.

The 613 was much faster but the 606 runs so well on veg and is much smoother than the 5 pot I'm the 250td
