Hey T's and Phil, that chart of WVO viscosity...
September 18, 2010 - 11:09am
Been watching the new nonsense at Fred's. Totally hilarious in that I hadn't lurked there in a few months as it got kind of boring, but now I return to the same old dog&pony anti-WVO show. Except that now Goodwin is in the mix. He's a total pisser and it's such karmic payback to Metz and the other nitwits. I actually think that Goodwin was most successful in making Metz look like an absurd fool even amongst all his rantings and ramblings. Popcorn worthy!
Anyway, that new graph was very interesting:

Unless I'm reading it wrong, WVO at 194F is the same as D2 at 50F. As I'm sure my WVO is very close to that right before it hits the injectors, it's not a matter of D2 at 32F by any means. T's, you should keep hammering on them to step up with some VW backup that the engine was not designed to run for long periods on D2 that is 32F, or any temp for that matter. They claim that due to the return warming the D2, it doesn't stay at (insert temp here) for long. Really? So on a morning after a -20F night, they think that D2 will warm up to something above 32F anytime soon? Hell, the pre-PD motors have trouble even generating cabin heat for the first 20-30 miles in those conditions. So don't let them off the hook, force them to stay on target, it's a fact that negates almost their entire argument. And yea, there are TDIs happily enduring long periods of harsh cold conditions in the central US, AK, Canada, Europe, etc.
To anyone who has no clue what I'm referring to, check out the antics:

I'm touched that BK still thinks of me! :-D

With current technology a a converted engine can be expected to have useful engine life nearly as long as if it were run on diesel fuel. The problem is that many conversions use technology and information that is far from current. And of course there are still a LOT of individuals that do not understand that wvo must be processed (dewatered) adequately prior to use as fuel or the progressive damage to fuel system and engine is completely predictable.
Most of the critics seem to focus on the damage done to engines sloppily converted or which usd fuel which contained too much water.

Couple of questions for danalinscott: what do you mean "last almost as long as a tdi run on d2 (paraphrasing)"? Why not as long or longer? You point to two separate issues that lead to problems: incomplete kits and bad wvo. Is there a complete kit out there for the tdi that corrects the technical problems of the older kits or is it just trial and error on an adhoc basis? and how does one compensate for the organic variables in wvo?
What is your take on viscosity?

Poopypants! Wassup, long time no see! Good questions and I'm curious to see what Dana has to say.
My personal take on the longevity aspect is thus: I already have 165K on WVO. If I had to spend $4K in engine repairs tomorrow that were absolutely caused by my 165K of WVO use and then I'd know I could go another 165K before spending another $4K in repairs, I'd still be way ahead in a monitory sense. Of course we all know the "car's" longevity is not affected by fuel choice, just components of the engine, sometimes large and expensive ones, sometimes small and inconsequential ones. But why do you ask if it could possibly last longer on WVO? Seems like an odd thing to wonder.
"Incomplete" kits only cause issues with uneducated operators. I guess a "complete" kit in my book would be one that was totally idiot proof and made for use with the average driver. No such thing exists as far as I know.
The differences in composition of WVO have made me wonder, though in my case it seems to be a non-issue. Possibly my extensive filtering/heating/settling process removes the vast majority of contaminants, or in actuality those contaminants and changes are a non-issue. Dunno.
But hey, is there another analogy to some people who smoke until age 90 coming? If so, do a search back at Fred's with the author being "chasee" and the keyword being "smoking". I soundly discredited that utterly infantile attempt at an analogy on several occasions, several years ago. But hey, maybe in some simpleton's brain, the human body is analogous to a TDI engine. Can't argue with stupid.

Sure you can take veg from the grease pit and run it in you car. Your not gonna get too far!
I think some are trying to find/sell the HOLT GRAIL of grease systems for the average dope!
Plug and play with grease does not exist!

""last almost as long as a tdi run on d2 (paraphrasing)"? Why not as long or longer? ""
Unrealistic to believe and engine specifically designed to run on petrodiesel will last longer on VO. Even "as long" is a sretch. To btain even nearly as long the operator must aware of the limitations of VO fuel use. For example for maximum engine life one should not use VO fuel when the engine is not at full operating temp. This is less critical on IDI engines than on TDIs. When an operator ignores this the crankcase oil becomes contaminated with teh fuel. Diesel merely dilutes the engine oil...VO polymerizes it.
"incomplete kits and bad wvo."
That is not what I said.
What I said was "The problem is that many conversions use technology and information that is far from current"
and
"wvo must be processed (dewatered) adequately prior to use as fuel or the progressive damage to fuel system and engine is completely predictable."
Most improvements in the early kit designs were a result of information developed publicly on the various forums. But in the past few years developmentof VO fuel conversion technolgy has been done in private. It seems to have been the pattern that kits are developed and marketed and at that point stop beign improved. I cannot say exactly why this is.
As for using inadequately processed WVO fuel. There has always been the problem of folks just wanting to beleive that they don't need to dewater adequately. And most kit makers have played down the need too. Add to that that in the past 3-4 years there have been a few individuals that promoted processors and tests that were very poorly tested. And of course there are some really badly engieered conversion components available.
The only current way to have a conversion that uses "up to date" technology is to use a good quatlity conversion and add componentst that are not offerred with the kit.
"What is your take on viscosity?"
Can you be more specific?

Seems Poopy vaporized back to Fred's again. Poopy, come on back and join the party you started! If you do, just curious, who are you at Fred's? Arnie?

I don't even understand what points they are trying to make. Even Nick this time is proving his blatant ignorance on the subject and he is the one with the most open mind out of all of them. That graph above even furthers our argument that with a well designed kit and adequate heating, viscosity is a non factor. Since viscosity is a non factor and WVO has similar burn and combustion characteristics to that of diesel, WVO can be done and done successfully for a long time.
They still haven't answered my question that if it is not possible to run WVO for the long term, why is it that people have put over 150k successful WVO miles on their car and to this day are still running like a clock. I guess this would be checkmate don't you think?
