still seems to me like the higher temperatures in the pre chambers really do help burn the VO, except for the fact that it takes a few minutes for it to heat up properly... and that is under normal driving... and so before that the fuel can do bad things inside. but still having a fuel mix should be ok.

Its the pump that is the primary concern, especially you VW guys since the pump depends on the fuel for lubrication. Cold oil is viscous and solvents have no lubrication benefit.

when we converted my dads truck to wvo it already had 2 tanks so we just heated the lines in the front tank with coolant. when the truck warmed up we switched to wvo!

im confused :?

are we saying you can use oil on a standard engine, or do we have to modify???

Biodiesel can be used as-is, WVO/SVO (besides being illegal as a fuel in the USA) must be heated before it reaches the injection pump.

What law states that its illegal?We collected oil next to some police the other day and they didnt seem to care ,and we werent looking very professional if you know what i mean(mechanical hand pump w/white poly drum in the back of a dodge prospector.

).

WVO and SVO do not have EPA approval to be used on public roads and most users fail to pay the required road taxes in states that do not exempt it.

The police didn't do anything because they were ignorant. They didn't know you were going to do anything illegal with it, they probably didn't even know you could do anything illegal with it!

Many places also have a contract with a removal company to haul and recycle the waste. If they catch you taking their oil they can prosecute for theft.

Thats fair enough, but the UK seems to have its own rules and rubbish about everything :roll:

you're not kidding mate! :roll:

Quote from: "UK Customs & Excise"

4.2.1 Exempt producers/users
If you have produced or used less than 2,500 litres of:

any biofuel, or
any other fuel substitute or additive
within the last 12 months, and/or expect to produce or use less than 2,500 litres in the next 12 months, you are an exempt producer and do not need to register with HMRC and account for duty. However, there are simple record-keeping requirements, which are described in paragraph 4.9.1.

Production includes the manufacture or processing of road fuel, and the setting aside of any product that has not been charged with duty, with the intention of using it as road fuel.

wrong wrong wrong :!: :!: :!: :!: :!: :!: :!: :!: :!: :evil:

you can blend svo with diesel as long as the temperature is above 0-degress celsius without any problems at all :!: we are many here that have been doing so for many years :wink: 50/50 is absolutley no problem at all :!:

no need to heat :!:

however it is better to heat :wink: you can run 100% veggi oil then and att any temperature :wink:

the only thing you MUST have if you want to blend is a prechamber/swirlchamber engine and preferably a mechanical bosch type inj-pump (lucas, electrical, DI, doesn't work any satisfactory and break easy)

the other issue to be careful of is that spraying cold VO into the cylinders can cause glazing of the rings and walls and coking of the injectors. Not an issue if the motor gets torn down every couple of years ,but if you want to have a long lasting motor and injection system then it's way better to use a 2 tank setup. I had VO valve problems in the early spring and had a blend of VO and diesel in my diesel tank. Truck started rough as hell , stalling ,hunting. Even in summer where it gets cool at night it would need a proper set up. I had a guy who was using alot of grease [not oil ] and in July the truck wouldn't start unless he took a heat gun to the injectors and IP. I got into this because one of my customers has been doing this for 15 years . He never damaged an engine but went through at least 3 pumps. He didn't have any preheating ,just some a homemade heatexchanger that was 3 inches long [how effective could it be]. Some tests have shown that if you don't heat the VO to at least 60 oC you are probably increasing emmisions rather than lowering them when it is heated. Anybody can do what they want to see what works, but
i will never run a diesel cold on VO again

been doing this myself for 2 years now 40 000km: i have no problems with cold start at -15celsius no rough starting, no additional smoke when cold.starting, no rough running engine and NO problems, been blending 70%vegoil 30% diesel in the summer and about 50/50 when its just above freezing and below freezing pure "crap"diesel

dino diesel gives a rougher running, more smoke and less power 1sec less on a 80-120km/h on 4th gear 3sec less on 80-120km/h on 5th gear :evil:

(and it also smells like ***)
