None of this surprises me. I don't think the corrosion is due to a bad batch of wvo...probably due to the corrosive nature of wvo in general. There is a Thai study in the literature where two identical diesel engines were run on palm oil for the same amount of time. Piston rings were weighed in each engine prior to and after running the engines. The engine run on the palm oil showed significant piston ring weight loss, while the engine run on dino diesel showed much less weight loss. This tells me that the corrosive nature of the acids in veg. oil wear out metal parts over time and this is part of the cost of running svo/wvo.

Do you have any sources for this information? Did they just pour cold oil in on there test? Oil is actually better for your diesel engine when added correctly. It's a lubricant. IMOP it's better then deisel because it reduces friction. Most of your problems are going to come from not filtering correctly and dewatering.

I'd like to see the IP from this truck with the bad injectors...

The truck does not use an IP, it is a Powerstroke, Direct Injection, electric fuel pump. It is a 2000 F350 with around 245,000 miles on it and 12k of that was WVO.
What may interseting to see if Swamps has not already inspected itis the condition of the aluminum fuel filter housing.

Oops, I missed your question.
We've had several sets of injectors come through our shop that had been running various concentrations of pump bio-diesel, mostly soy, I believe.
The injectors were very clean, in excellent condition, and when you rubbed the fuel inside the injectors between your fingers it had noticeably better lubricity than #2.
We've also had a lot of injectors where the fuel had a red color to it, and it didn't cause any problems, either. [img]/ubbthreads/images/graemlins/wink.gif[/img]

There's your problem. Can you say capsacian(sp)?. You know, that hot pepper stuff they use in hot wings and bear spray. Those wings (especially the nukes) will rust MY pipes!!! [img]/ubbthreads/images/graemlins/eek.gif[/img]

Sure are good though. [img]/ubbthreads/images/graemlins/laugh.gif[/img] [img]/ubbthreads/images/graemlins/smokin.gif[/img]

Swamp, thanks for the heads up.

Haven't tried WVO, but have been thinking about a Biodiesel setup.

I am inclined to agree. When I was much younger, my parents would take us out to eat at this seafood place.
While we were waiting for our supper to arrive, my brother and I would pass the time by turning OLD pennies to NEW pennies by coating them in Texas Pete. Texas Pete would make those pennies SHINE... [img]/ubbthreads/images/graemlins/smokin.gif[/img]
Just another thought.

Oooops my bad, guess I should read more closely [img]/ubbthreads/images/graemlins/tongue.gif[/img]

Ya know one of the places I get oil they used to put the degreaser in the fryer with water then to the dumpster with it all mixed. If you had someone with really toxic degreaser, could it produce this effect? [img]/ubbthreads/images/graemlins/shrug.gif[/img]

TruckerDon · 09-18-2005, 06:22 PM

Yeah, that was a theory we tossed about. The other was they might have cleaned the vent-a-hoods with easy off and let that drip into the oil, then took it to the dumpster. That would've been quite a few cans of easy off, though. I'm pretty sure this particular oil was the problem, as I've run quite a few gallons of WVO, and quite a few gallons of diesel, and the only time I've had any deterioration in drivablility was when I used oil from THIS particluar drum. Whatever it was, it sounds like it was quite caustic. I haven't seen the parts, yet. There is also the possibility that there was some kind of reaction that occured with the diesel, heat, and temperature that exacerbated what might have otherwise passed though unnoticed.

It would also be interesting to know how protected the area the WVO was stored in at the restaurant. I've heard stories from the collection guys and restaurant owners about people dumping in the tanks. From old motor oil to all kinds of chemical waste. Most places around here keep the collection tanks in a locked shed now. It may have been nothing the restaurant di that caused the problem...

BTW I'm curious about the condition of the rest of the fuel system and the injector cups.

TruckerDon · 09-18-2005, 10:07 PM

I took a look at the injector cups. Nice and shiny brass. The fuel bowl looks like it's in good shape at a glance. I haven't had time to really get in there and scrub like I plan to. I haven't dropped the tank yet, because I've still got a few gallons to drain out of it.

From now on, my grease will come from a few places that I've spoken with before hand. It will also come in the cubies. I'm still going to run grease, but I have learned something about what I should burn. If you have ANY bad mojo about the grease you're collecting, leave it alone!

cranetruck · 09-19-2005, 06:55 AM

I have been running on a mix of homemade biodiesel, WVO and petro diesel since April, 2005 (1,000 highway miles and 80 engine hours). The engine loves it. The milage and engine hours may not seem high, but it is a vintage military truck and it isn't exactly a daily driver. The measured pH is about 8.0 (slightly caustic). No problems yet, but then I havn't pulled any of the injectors for inspection either, perhaps it's time to do that...

blitzlaw · 09-19-2005, 10:08 PM

I don't reccomend that you send me an injector because I read the removal and installation tutorial on your page and was a little intimidated by the thought of swapping one out.

I know where I'm going when I need to buy a set tho!

P.S. do you sell plain old rebuilt stock injectors for non-performance types like me?

Year and model of truck: 2000 F250

Current mileage: ~105k

Mileage when you started WVO: ~86k

Months/Years running WVO: 16 mos

How you use it (filtration, processing, % mix with diesel or 100%): 70/30 diesel/WVO mix in stock tank; Greasel Nomad system 100% WVO as much as possible. Probably 98% of the time.

Any other pertinent information: Oil comes from 1 main source; fried chicken/fish shop with straight soy (read the cubie) and changes oil at least once per week.

Thank you Swamps!

TruckerDon · 09-19-2005, 11:58 PM

Blitz, it's not that bad. I've never had mine out, and they were sitting on the floor in about 3 hours. It took me a minute to figure out how to pry 'em out, though. I was scared I was gonna break something.

Don.

Swamp Donkey · 09-20-2005, 03:34 PM

Blitzlaw, Fordnut74 and RoReRi: you guys have enough miles on your setups for me to easily spot any abnormalities in your injectors.

PM me your address, and I'll get an injector ready for each of you.

Yes, we do stock rebuilds, too. :yawn: [img]/ubbthreads/images/graemlins/biggrin.gif[/img]

RickHredf250 · 09-20-2005, 04:36 PM

Swamp,
If you are short on stock rebuilts, let me know. I still have the one I bought from you last winter.

It's a lot more complicated than you might think.
