I been running bio for 4 years now, And i turned it on to a buddy mine, But he has ended up running 100% veggi with keroseen, hes doing a 100 gallons of SVO to 10 gallons of keroseen to thin it out a bit,
question is, what would be less polluting ? the SVO with keroseen? Or the veggi mixed in to bio with lye/methanol ?
i know the svo with kero, Would be alot cheaper/easier but how is keroseen beening burnt?
thanks.

A little clarification. Biodiesel is not vegetable oil MIXED with lye and methanol. Lye and methanol are used as a catalyst to make the glycerin drop out of the oil. This is not the same as mixing SVO with solvents, which is what you're describing with the Kerosene. Thinning with solvents quite simply is playing with fire. The only way to safely use SVO in a diesel engine is with a heated two tank system or a specially designed one tank system with solvents AND heat. Even then it's a little dicey.

I understand its totally different I dont see how its "playing with fire" nor is it Dicey to run vegi oil without a two tank system.. Can you explain?
I've known several people to run 100 vegi on a two tank system ONLY to start.. one the it started it was switched over to "cold" vegi oil.

Wha? This makes no sense. The way a two tank system works is you have a stock diesel tank and a heated vegetable oil tank. The truck starts on diesel and coolant is circulated around the SVO lines/tank. Once the oil has reached an acceptable temperature (160-180 degrees) the engine can then begin drawing oil from the SVO tank for use as fuel. Feeding any diesel engine cold vegetable oil will result in coked injectors, deposits, and premature engine death.

In what climate? In CA. I've known people to like I said, Use one tank with bio-diesel to start, and one tank of vegi oil UNHEATED and had NO problems..this is in a 95 f250, with Two tanks( not a two tank "system" ) Maybe this isn't the same thing your talking about.
now I live in Hawaii Ever heard of it? its much warmer then a place called new jersey,
I know someone here running the kerosene and vegi oil mix as I mentioned before, this in his cummins, with big sticks/turbo and all the supporting mods..hes also a mechanic, so I suppose he can afford to break something..?
I dont feel I'll run in to these same problems as your talking about..no one I've known on the west coast has even had problems with "cold" vegi oil

Unless you live in Death Valley, paint your WVO tank black, and let it sit in the sun for 3-4 hours before you start the truck the oil will never be hot enough to use safely. I say use safely because you're absolutely right, in places like Southern California and Hawaii you can absolutely blend SVO with diesel and it will work-for a while. I've heard of Hawaii and I also know enough about it to know that the average daily temperature is not 180 degrees. I give up at this point because I'm simply resigning to the fact that there are going to be lots of nice trucks with blown motors on the market in the next few years which can only benefit me

haha, ok deal.. so, do you have any clue of the pollution of kerosene? by chance?
If I were to do my dicey playing with fire like blend.. is kerosene a good choice?

Yeah, you probably aren't going to like this, but ...
First thing to do, if your priority really is to be "less polluting", is to turn the tuner back down to factory specs and restore the EBPV. Overfueling and overadvancing yield a lot of NOx or CO, maybe both. Radical overfueling yields a lot of PM.
After that, burn a fuel which is the same viscosity as the pump & injectors were designed around. Not only will a higher-viscosity fuel put additional stress on the fuel system components and shorten their life, it won't atomize adequately to ignite reliably and combust completely in the short time available between injection and bottom dead center.
Kerosene is about the same thing as #1 (winter) Diesel fuel. It burns fine but may or may not have sufficient lubricity for long pump and injector life. It's a lighter fuel than #2 Diesel which contains less energy per gallon; a gallon won't yield as many miles. Since it comes from the same base stock and same refining process as #2 Diesel, I find it hard to believe that the price per mile is any different. (unless felony tax evasion is part of the calculation)
"SVO mixed with kerosene" is a bit of a misnomer. SVO doesn't always mix well with petroleum products. Simply pouring the two into the tank won't cut it; an actual mixing process is required, and possibly an emulsifying additive.
Strictly speaking, it's dynamic viscosity, not kinematic, which determines behavior in a Diesel engine's fuel system but since all feasible fuels are close to the same density, either one is close enough for practical Diesel engine work.
