A good reason to run B100 over SVO - Diesel Forum

For those with doubts about the damage SVO systems can cause, see this story,

TDIs are known to have issues running SVO and everyone that runs SVO knows what can happen if they dont care about preventative measures. Some have great success other fail, way too many variables with SVO.

wow. thats sucks.

CRAP, that's crazy!

I read that story too, but the problem is in his post, he doesn't have any facts about the kit, processing oil, or temp or build of the system. Some people have problems with some cars, and some people don't. I understand that not every car/ truck is a good match for WVO. But still if done right, greasing can work out. You just have to fallow the rules.

He pretty much admits that he didn't dewater his WVO, too. The valves look like he never waited until his engine warmed up, and didn't really heat his fuel either.

Even still, no way I"m running WVO heated or otherwise. I had to tear down a friend's 6.2L GM that had seized due to running WVO.

Even heated it scored the cylinder bores and left this peanut butter consistency goo in the bottom of the pan.

While I'm quite sure alot are running WVO successfully in their vehicles, I prefer running a fuel that's thinner by default and has gone through a rigorous chemical and mechanical quality process before running it even in the old Powersmoke.

I think I would blame the people/kits that claim you can run margerine and hog fat in a diesel on that one. Especially the ones that claim you can dump it straight from the cubes into the tank. I'm not saying that is what your friend was doing, just that he may not have been as careful with the quality of oil/proccessing he was using as he should have.

The stuff I get is pretty good quality as it is, but I boil it and filter it, then remove the stuff that settles and congeals or whatever. The only ill effects I've had so far was a few seals leaking after it loosened all the gunk up, and it doesn't really do that anymore.

I see you have a cowl induction on your truck, do you have any pictures of that? I want to do something like that on mine in the future and want to see how it is done before I go cutting holes in metal.

Yeah there are certainly many variables to account for using WVO.

I personally chose to eliminate most of those variables by making biodiesel and only running it in my truck when I had the process down to a high-quality consistency.

As for cowl induction, Hypermax has the cowl induction scoop on their website for the 6.9 diesel.

What I was thinking about while reading this was:

The TDI's are known for superior fuel mileage. Why worry about getting free waste oil and taking a chance of a major engine repair or replacement.
The pay back in fuel saving by owning a TDI is enough to bring a smile on my face.
I don't own one but have been looking for a deal for some time.

Good luck to all of you who are paving the way with alternative fuels.

Ok maybe I am missing something here but how does WVO cause turbo damage, cylinder scruffing, and intake valve build up on a direct injection system. I am new to BD and don't want to run WVO but I don't think the damage to that engine is due to WVO. I think he had poor air filtration that took out his turbo and damaged the piston and cylinder and as for the build up on the intake valve a poorly operating CCV system. I don't really know but that damage doesn't seem to jive with a WVO issue.

I had a long conversation with a guy from British Columbia who has nearly 200,000 mile on his 6.9 IDI run WVO, was he lying to me? I doubt it!

Spencnaz · 08-06-2007, 06:53 PM

The IDI 6.9 is very tolerant of fuel quality. I joke with people saying that my truck could run on boiled horse pee and not know the difference.

The kicker with WVO is dewatering, near fanatical filtration and lots of heat before it even enters the fuel injection system.

WVO doesn't address the free fatty acids issue that is eliminated by turning WVO into biodiesel. Washed biodiesel not only removes all these free fatty acids, but also water, alcohol and any other particulates and is much less viscous than WVO further removing undue stress on the injection pump.

WVO can kill the IP on the 6.9 IDI engine if it's run too cold, I have heard of instances of poorly warmed WVO causing the input shaft on the IP to snap due to excessive shaft stress.

luckys420 · 08-06-2007, 07:05 PM

something else was happening with that guys car. it seems he was getting incomplete combustion for some time. What did his intake look like? how clean was his air filter? Clogged snow screen? OIl changes? Did he mention any of these factors?

Spencnaz · 08-06-2007, 07:09 PM

What I found the most alarming was the accumulation on the valve stems, I mean how would those valves be able to close with that much crap on the stems.
