still using my cheap fuel mix.
-5 this morning,started on first turn de iced and drove 70mls with no probs.
t2 been on field unstarted -0 for 2 nights for new year with caravan.
my wvo is pretty good,not changed filter socks for year still pay 2.50 for 20ltr wvo,any wvo i cant use is mixed with wood chippings and shredded paper and pressed into cardboard tubes to make logs for my wood burner.so no wast apart from some ash.dustman takes that.
peps can use what fuel they want but this is my choice.

I love that you can use all the waste waste as well... well done.
 
Only one answer, don't run veg oil. Amount of headaches I have had to deal with from folk running this **ap is getting boring. How many injection pumps does someone have to go through before realising the saving isn't worth while....? Fungus solidifying engine oil, engine may as well be scrap.... I just wouldn't consider destroying my car......

:clap I agree 100% :thumbs
 
Actually, since I have been here I have not seen one person mention a fuel pump had died due to veg oil?

Incorrect use of veg oil can cause issues and as we know rubbers will be attacked. But the savings I have accumulated from running veg pays for a pump if it were to fail.

From the research I have been doing I am always prepared for pump issues due to the chatter I have read, but I believe the failing of the pump due to the viscosity of the liquid you are using over a long period of time.

In simple terms, use too thick a mix for a long time, you are causing the pump to work very hard. A good mix needs to be achieved so the pump and injectors are working efficiently.

And a clean out of the system is needed every once in a while :thumb2

Just my views.

You may save money for it but what about money for someone in the know to troubleshoot it. You could change the pump and it still could have the same issues as it wasn't the cause.

Run veg on a old motor but not on something thats cost me 1k+

I'm happy enough to throw veg/bio/derv/petrol at my pump and am fully aware of the implications that this could cause to the pump and mines an 04

I'm well prepared to get my hands dirty and pretty sure I'd be able to fix my pump should it fail, if not, I'll source a new pump, in the meantime, I've got a bike :augie

I agree, it's totally up to the owner as to whether they want to 'risk it' with fuels other than straight pump diesel. Remember that pump diesel used to need a winteriser adding, indeed many early diesel cars recommended up to 20% petrol to a tank of diesel in deep winter to stop waxing. Better a less lubricating fluid that the pump can actually move, than wearing the pump out due to waxing diesel. I recall lorry drivers lighting small fires under their tanks to get their engines running (yes I'm old!)

Loads of us on here run veg in various blends, equally there are loads that don't. Veg has it's risks, but if your mileage is enough and like me you have plentiful supplies of used veg oil for free, then even allowing for heating it up (about 50p for 200L), filters (1 pack of J-cloths a year) and the extra for some petrol in cooler months, I still fill up for under £20 a tank on a regular basis and have done for years. I've saved loads more than the truck cost to buy, so, at worst case, a new truck would still be cheaper every couple of years.

I know the risks and accept them, others prefer not to, but I feel I'm more likely to be written off by some halfwit rear ending the damn thing than the engine being completely irreparable due to using veg. But that's just my view, everyone has to make their own minds up.

To answer the original question posed, diesel like all fluids gets thicker as the weather gets cooler. Adding it to the veg will thin the liquid, but never as thin as diesel itself. Adding between 5-20% (no more than that) to the fuel will bring it down to roughly the same viscosity as diesel as petrol is indeed much, much less viscous than diesel. If you are using recycled veg, then petrol may strip out any 'extras' still in the fuel like water not released properly, hence us WVO users tend to mix it outside the tank for a day or so before using. It also speeds up filtering in the cold weather too.

I am currently using WVO with 15-20% petrol added plus topping the tank with diesel to keep my tax dollars up :D I wouldn't bother with diesel accept that a lot of my journeys are quite short and therefore the engine doesn't ge to run at full heat all the time, on a long run, 100% WVO all the way.
 
with ref to pumps,i took on a 99 t2 been on pump fuel all its life and i got it from same owner who had it 8 years,but it came with a fuel issue that he had and been into nissans for but not rectified.
this is how i came to this site looking for answers for the problem.
not going to repeat all but in the end after a year of unreliable towing t2 finally gave up the ghost.hence that is how i have two t2 now.
my brother said it was the ip,i was sure it was not but he was right it was a failing ip on the pre ip pump.
i got another ip from here changed it and all fuel probs solved and its running on my mix like a good un as is the other t2 i have.
the ip had pump issues on pump fuel alone.
in 20 years of wvo use i have not killed an ip,front seal leaked on a bx 200.000 mls but not killed the bosch pump.
i ran a zx 23.000 mls on wvo a lucas ip and did not kill it.
pumps go,poor fuel might help shorter shelf life,water in fuel is a killer.
it costs me no electric to make my fuel just time and pillow cases and graverty finally through 1mic socks,if i suspect water i put the container in the chest freezer then as it thors out pour off the good oil.any water in it stays frozen then is poured over my logs to burn.
 
So I think we can agree, common sense is in order, and amongst other things making sure the right mix is applied in the right conditions :thumb2
