Hi, Well I'm in to my 3rd totally trouble free year of my homebrew twin tank wvo conversion that is until yesterday
This is the very first time my supply hasn't kept up with demand ( My Grant boiler also uses it)
So I paid Bookers a visit and bought 40lts in 2x cubies.Its exactly the same as my pub uses and cost £40. Well I put it in my spare tank in the boot in with the remains of the old stuff (about 3lt) The first wierd thing I noticed when setting off the next morning was by the time I passed the landmark where the veg oil is always up to temp and ready for the switch, it was hardly warm at all ?? Anyway it was cold so left the switch over for another 3 miles. As soon as It switched she cut and I had to take to the verge.
On inspection , the disposable filter I have just out of the tank was choked with creamy white gundge? So, changed It , and away she went without any further glitches.
This morning-same thing? I'm now thinking there's something in their oil that cooking removes.As I said , I've never had so much as a misfire on the wvo and thats over the winter in all weather- weird hey? It does say on the box that it is soya oil with an anti-foam additive?? Anyone got any ideas please |

Quick update, just removed the tank and tipped it out . The last 3rd was like thick white cream.Had a look in the new container which had about 4pts left in it and sure enough its thick and creamy,and thats NEW oil??? Just carried out a hot pan test and no spits at all!! so what is it in the oil?? I can't see that it's just because its cold since the wvo has never done this even in far colder weather.
This is going to be an ar-e co's if I use it whatever's left will gell up again for the next morning.Would maybe this be a case for adding a little petrol or kerosene? |

Puzzler. I use Bookers svo all the time with no issues. That said I have never run run wvo. The filters do block initially when it pulls all the gunge out of your tank. But who should do this as well.
My two thoughts are:
Try a different oil from Bookers. Rapeseed or something.
And is it possible that your wvo isn't pulling the gunge out of your tank, but the svo is? |

It's a strange one hey! Because I've a dedicated veg tank in the boot and its transparent it does'nt have any gunk in it to come through, that is until now I've used the new stuff?? The creamy gunge that I poured out of the tank that blocked the filter has now turned back to clean oil again .It seems , for some reason, that the new oil is affected more by cold than when It's been used since all my used oil kept out in a shed is ok but the new is thick and creamy?? I would hate to be using it straight in my diesel tank.No wonder the single tankers have to add so much other stuff if this how it performs in the colder weather. |

maybe you have there palm oil?
a friend gave me a small amount of oil to test on my swb...it was red with some small parts in in, but very liquid...let it in the unheated garage...next morning it was all white and ...cream...next.... STONE
tried to mix it with petrol and diesel after heating it a little and made it liquid again...let it to stay on the night, and surprise...no jelly next morning
so...keep in mind that palm oil is normal to became solid, even at positive temperatures:) |

No it's definitly soya oil, it's almost like water with a hint of yellow. I've just done a 120m journey on it but I had to keep it in the garage the night before then fill just 5 mins before setting off. Now I know it gels so easily I can get round it.Its just strange that in two years of using the same oil but after its been through the deep frier,I've never had any issues using it even in sub zero conditions. My gut feeling is that its due to the anti-froth chemical that it says it contains.This must get removed with the cooking process. If I was using it in my main diesel tank I'd be concerned, you'd be much safer in my opinion using used stuff with your diesel. |

sorry, i just saw you talk about "unburnt" oil
yes, u're right, a lot of people claims thatt the new oil must be cooked for better results because of some fractions of "i don't know what" must be cooked (sorry, i was not good at chemistry)
anyway, thanks for your advice, but relax, i will use ONLY cooked oil because that is the only that i can obtain at a good price |

I had some KTC from Makro as back up, went to use it and it was completely gelled but stayed clear not creamy white, I had to take it inside to warm up, then add petrol to keep it liquid. I normally use the same stuff as WCO with no problems at this time of year. |

Just a thought.
What way is your return pipe run ? in to the main tank or the oil tank.
If back to the main tank oil will be getting in to it.

Hi Bob, the return is switched by the Pollock valve so it returns to the appropriate tank, BUT- during the flush period it dumps the pipe's worth into the wrong tank. Not a problem with diesel getting into the wvo tank but I do notice if I'm very low on diesel that the starting is'nt so sharp on a cold morning.
When I had the breakdown it was running great on diesel, it just went tit's up from the moment Iflicked it over to the veg tank.
I've now got my wvo supply back on tap(pubs re-opened for the season) so am on wvo again That can stay out in the cold and never gives a problem. I'm certain it was to do with whatever it is in the new oil causing the gelling at higher temps
Cheers for your thoughts. |
