Just got done doing some interesting testing looking for polymerization, and ways to prevent it. Now this is just a prelimenary test, and I need to back it up with a duplicate test, but the results were interesting to say the least. I can't wait to follow up on this with some more testing. Let me know what you think....

Very cool. Thanks for your effort. I'm also curious about reaction with other metals.

I've seen the most severe polymerization in a steel tank w/copper heat exchanger, and also saw it in an aluminum tank w/copper HE.

It is interesting you didn't get the reaction until higher temps...
Those temps are much higher than most would see in a conversion system or even pre-filtering.

Keep up the good work!!

VERY NICE!

Keep up the good work!!!

It would be interesting to see that test done with BioDiesel.

Again, I applaud your work! Its folks like you doing these experiments that bring knowledge to these forums!

Yep, this test was only a starting point. But I was certainly encouraged to say the least. In lieu of these findings there are about a thousand different combinations I want to try to see if we can fully understand this. I will certainly be trying Biodiesel, and and some different metals along the way. Right now I have started test 2 that is using progressively less and less diesel down to 40:1, and then a 10:1 with DieselKleen, only diesel, and only WVO.

Great info. I will for sure be adding #2 to my mixture. The pictures speak for themselves.

As a previous reply said, use biodiesel to see how it affects the WVO also, that could be very interesting. In the top three you could try straight biodiesel, strait WVO, 10:1 WVO:BD. Then duplicate those tests inthe bottom three cups. It might be best to try three variations at a time, with two of each for reapeatability in identical conditions.

As as a side note Jason, if y'all are using #2 in the primary tank with a veggistroke-type configuration, the purge would input #2 into the veggy tank as a matter of course. It would be a function of tank size and purge time to target desired #2 and WVO ratio. If your preliminary 10:1 results with No. 2 are any indication, I feel alot better about a few of the steel fittings I have in my system!!

Thanks for the hard work.
