WVO Mixing Ratios

Unread post by **Rhothgar** » 31 Jan 2011, 20:09

Hi all

I am appealing for urgent information please (well - sometime before tomorrow lunch) as I am about to do a wvo fill-up tomorrow.

The local guy who deals in it says I should mix 50/50 and gradually increase the ratio to get my engine use to it. Not sure this is really necessary!

More worried about the current air temperature to be honest!

What are some of you guys currently using ratio wise for the current air temperature?

Also the guys states it is better for engines because it lubricates better than diesel which is probably true but does it not gum up the inside of the engine? Anyone done a stripdown?

Also he tells me he doesn't filter it he merely heats it and this separates stuff out and he extracts from the top of his tank.

At £1.05 a litre, I am wondering if the benefits can be outweighed by any potential trouble. Obviously, the fuel filter will pick up all problematic particulates.

A sticky might be a good idea for WVO points around the country?

Comments / Camaraderie appreciated!

Personally I think it is rather overpriced for being virtually untreated chip fat.

I agree with the above, i've never used wvo, only every used nice clean SVO & only when its on offer.

I presume you have a bosch pump? If not, then don't even bother, although veg will kill a bosch pump over time anyway. I personally never use veg oil when its winter time, it puts too much strain on the pump imho, only in the summer.

At this time of year i would not exceed the 50/50 balance , the colder it is the less well my car(s) have run on veg oil.veg oil loses a lot of it's viscousity
when very cold and this puts a strain on the fuel pump/filter .
The price seems to high to me i would investigate the validity of the claim that it is 'filtered' .

without a bosche pump you should not even consider doing it .

i'm not an expert mind , but have run citroen diesels on svo and filtered veg oil mixed , for a year or more .

Remind me please? SVO?

I thought it expensive but it's still £20 based on a full tank. Seems to ge not worth the hassle for £10 saving on basis on 50/50.

He adds some chemicals then extracts them after they've done whatever they are supposed to do.

Which one of you built that really nice portable WVO system with the copper pipe?

Unless you're making biodiesel...you wouldn't add anything to WVO...

This chap seems suspicious to me.

SVO - straight vegetable oil, the sort that supermarkets sell off the shelf, cheapest place i know to get it is Costco in 20L boxes for approx 90ppl (normally it's cheaper but then diesel is around 132ppl).
Running Cassy on that at 100% at the moment.

Do not go near WVO unless you are certain it has been properly dealt with to remove the water/acids/debris from it, and always keep a spare fuel filter and allen key in the car.

I'm not liking the idea of that. I used to use cold filtered WVO for a couple of years without too many problems. My concern would be all the crap that must be suspended in his oil.

My suplier used to swear by WVO untill they replaced their old IDI transits for more modern DI engines. One tried a twin tank system and the other decided that he would go back to diesel.
They carried on selling WVO and then decided to produce biodiesel so that they could continue to run their delivery wagons on the stuff. I much prefer biodiesel now.

Regards,

Steer well clear of this guy, you can get brand new oil (SVO) for less than that if you shop around. The going rate for properly filtered WVO is around 40-50ppl, and this guy isn't even properly filtering it, from what you have told us. Heating will help seperate the water, but I would suggest at a minimum the oil should be filtered to 5 micron or less.

You mention he's adding chemicals, are you sure he isn't making biodiesel? That would be more realistic at £1.05.

Can you confirm what engine and fuel pump you have?

Not to mention, if he's flogging WVO as a fuel and for profit, there are possible legal issues to consider.

I'm wondering whether this chap is making biodiesel without realising...or attempting to do so anyway.

Given the information that he adds chemicals, heats it up and siphons off the top layer...

Just a thought, could account for the price.

That or not stop to think about something else in the middle of a post...

Sorry. I should have been clearer. It is Biodiesel made from WVO.

It just worries me that he doesn't filter it. He did say to me that I should carry a spare filter with me and to probably change the filter after approx. 3 weeks as WVO / Bio has the ability to flush your system through quite well.

Another question! So... from what I can make out, a Bosch Pump is suitable for use with almost anything? Biodiesel, WVO, SVO?

My car is RP7099CJ - does that help?

I wouldn't put anything in mine that wasn't filtered ,and filtered well.Your asking for trouble sounds to me like the guy doesn't really know what he's talking about.At £1-05 it should be excellent quality bio-diesel but doesn't sound like it is.

Hi Xac

Is Cassy behaving herself at these low temperatures on SVO and I mean 0 - 7 deg. C?

Also, had a look at the CostCo website and the nearest to me is a 35 mile round trip. I could get my brother to pick it up as he is nearer.

On another issue, is Costco worth joining to buy other provisions? Is it really so much cheaper? Their website doesn't give too much information anyway on pricing but does state that they sell to businesses for resale. Do they do LHM for instance?

So Bio is OK for use on Bosch Pumps and also HDi engines? - my brother has a 51 plate Peugeot Partner and he has just started using this 'BioDiesel' from this guy. I'd better check he's got a Bosch pump too before he puts more in.

How is it possible to tell if it is Bio and not just WVO which has been heated and skimmed? I did see what was allegedly a sample which looked immaculately clean and a light orange colour. Presumably straight diesel is clear? Just wondering if he has a sample of something different to show people.

hi Roth, agree with most of above, as Evilally and others say, price is not right for WVO, but seems about right for Biodeisel - which you dont need....

I am paying 45ppl for basic clear brown WVO, and I run about 80% even in the current temps..

I have been doing this in my rebuilt-engined Xantia TD for 2 years or so ..
(the rebuild was nothing to do with fuel )

A couple of filters, and an ungumming of the boost metering needle so far is all i can report really.. about 40K miles I think..

I would probably suggest a rebuilt bosch pump at hand, for a 2 yearly swap and service.. it's what I am thinking now.. although mine carries on going with no real problems

Glad you confirmed that John!

I am based in Nottingham. How would go about finding a supplier of waste veg oil that is filtered? Just do an internet search?

My current thinking is at least Biodiesel is at least 26ppl chaper than diesel around here at the moment and any saving is a bonus!

I can't my head around when the guy who is selling would say mix it 50/50 for the current temperature and to ease your engine into it.

I banged some SVO into my partner's ZX when she went on holiday with her folks the other year. Ran like a dream but did spell of a chip shop. Oh how she loved me for it!!
