Hi in some places like NZ/Aus the cost of additives such as Unleaded+Kerosene can compromise the free or low price of WVO.
EG here our price of diesel is $.65/L (all prices $US)
Price of Kerosene is $1.50/L (15% by volume, or 23 cents/L)
Price of RUG is $0.80/L (5% by volume or 4c/L)
Typical price of WVO is $0.05/L
Say price of additives is $0.05/L
Price WVO blend/L = $0.37
Of course, prices are approximate, but interested in comments.
What would be good, would be a much cheaper alternative to RUG/Kero. I understand in some places you can get waste unleaded, but not so easy to find here. Cheers. Al.

Here in Northern Canada
diesel is currently $0.82 US/litre,
biodiesel $0.79 US/litre,
kerosene [no tax arctic stove oil] $0.74 US/litre,
RUG $0.72 US/litre,
WVO, free
stale dated jetB, free

Blending diesel with VO or BD + jetB saves a little money, but more importantly it significantly cuts tailpipe emissions and gives clean starts with no smoke or black soot on the snow.
Even at winter temperatures below 0°F [-18°C] I still run blended fuel. It's simply a matter of adjusting the blend for temperature so it does not gel in the tank.

Not Sure I understand what your concern is about. To me, I interpret it as " The cost of Blending isn't totally free".
Certainly not in most cases but it can be if you are fortunate and put n the hard yards to find an source of free thinning fuel.

When I tell people I Blend and instead of paying XXX a litre for Fuel I'm only paying XX, They never seem to fail to wish they could get their fuel for the same price/Saving.
Anything Below the cost of Dino is a Plus to me and it seems silly to say the saving isn't as big as it could be if it were free.

To find free blending agents, you have to look around. There are lots of accounts on here of the different thining agents people source and where from so I suggest have a read through and see what you may be able to get.

People source "Waste" fuel from airports, Marina's, mechanical workshops etc. If your not fortunate enough to have anywhere nearby you can get waste thinning fuel from, even If you have to pay for Unleaded, it still has to be cheaper than Dino. If your blending say 15% unleaded with free oil, it's still cheaper than full tilt dino by a long shot.

Maybe you can't blend all year round and at some times have to use regular Dino. At the end of the year, you have still saved money so best to count your blessings and think about how far you are ahead of all the rest of the poor " Unenlightened" people out there.

We are trying to use renewables to be as earth friendly as realistically possible while keeping costs down.

Thanks guys point taken. I should have explained because I have many contacts as farmers who are busy enough without spending time making fuel from WVO, I need to present a good argument to them. Simply environmentally might get 10% involved but 90% would be if they could justify the labour involved, and they saved at least 70% on costs of diesel. Maybe the way to win their hearts is to get some form of waste RUG in quantity from the airport and arrange freight to them I dont know.
Have found a ready supply WVO from most restaurants in the area, but all charge as there is already a service which picks it up and pays $US10/60gal.

Lucky to get your WVO free. I guess your diesel is more expensive than here because you dont have 'road user charges' which are an additional tax here paid on top of, and separately to the fuel price. NZ Governments idea is that all fuels should be priced about the same otherwise there would be pandemonium folks getting rid of gas engines for diesel.

Not luck so much, but well developed relationships with restaurants who like the idea of their otherwise waste fryer oil being used as fuel.

Oh yes we have those too, about 16% of the diesel fuel price and 20% of the petrol price is tax. The difference between the two is also driven by supply and demand.

I bought my wvo for $2.02 a gal. delievered.I mix 30% diesel.Its the helping the small guy out,and lower polution I'm after.I can't stand paying for Middleast Oil.

I find may "persons" interested in wvo fuels. but most of them are to lazy to make it for themselves or collect the oil. NO wonder we have environmental problems .. but
most of them want me to do the leg work so they could get fuel below 1.00 a gal.
No thanks as far as finding wvo i have had no problems. i also have found a very large supply of stale rug. all other additives come from amsoil and tractor supply. my cost per gallon .39 cent per gallon.

No I'm not lazy,there is a rendering company in Tennessee thats got all the wvo.No chance to get any.Problem is they offer grease trap cleaning.You need a large truck and someone willing to buy it for animal feed.

cost of blending i get wvo free from resterants old kero from engenering work shops i let kero settle for several weeks in 200 ltr drum all i buy is uld petrel i have been blending for 4 years now .i settle my wvo in 1000 ltr tanks for up to 12 months the oil of the top is like new oil my blend is 100lts wvo 10 ltrs kero 5ltrs ulead petrel iff weather gets to cold i add a little pump diesel i have no trouble starting on cold mornings no loss of power. i have tried just about all blends on this site.i also had 1000 ltrs of hydrolic oil witch i used same blend had no troubles moter went just the same i still read all your idears and still leaning better than buying pump fuel all blenders dont stop good luck
