kyhiboy- My hats off to you

. At least you are able to reasonably substantiate your statement. Most who make the "destroy your engine claim" back it up with either "because it will" or my "friends sisters 1985 mercedes with 675,000 miles on the engine was running on a single tank unfiltered WVO system and toasted the engine."
However that is where my concession ends. Problem with most studies and reports is that they reflect the intent of the person writing/financing the study. And it is obvious from this study that the publisher wanted to impose a negative overall feeling about WVO/SVO as fuel.
The part of the report you published is so vague on the study controls it is to the point of almost being useless.
1. What engine/s what this study performed on?
2. Was the engine properly broke in?
3. What type of injection system does this engine have?
4. How many miles/hours was the test performed for?
5. Under what loading conditions was this study completed?
6. Was engine failure actually observed?
7. What types of oils were used?
8. Was this engine started and shut down using diesel like most modern WVO systems?
9. If they did mix, at what concentrations did they mix?
10. How much bleed by was observed into the enigne oil?
11. How much MORE engine oil contamination was there when using SVO vs diesel
12. What was the negative impact of engine oil contamination?
13. Was the engine oil changed at the manufacturers recomended interval?
14. Did the engine oil contamination cause excessive internal engine and bearing wear?
15. How much was the wear beyond the equivalent tested engine under the same conditions?
16. Exactly how much engine life was reduced?
17. What was the specific vicosity of the oil being used when introduced at combustion chamber temoperatures?
18. Was the injector spray pattern observed at engine temperature or at room temperature like most injector spray pattern machines operate?
19. Exactly how much was engine life reduced? more then 10%?
20. Does biodiesel require no storage considerations over normal #2?
I could go on for quite a while. It is apparent to me that the conclusions reached in this study were heavily influenced a Pro-Biodiesel comittee.
A famous quote goes something like this “Once you eliminate the impossible, whatever remains, no matter how improbable, must be the truth.”
No matter how improbable, what remains is that many people have used SVO successfully for extended periods of time with little to no engine problems when done responsibly. Regardless of the findings of that study, their conclusions are not accurate.
I probably have about 20 customers who now have over 100,000 miles on oil. With their original engine. One customer in particular has over 100,000 on oil, and over 300,000 total. Original engine and injectors. And there are even a few 6.0's in there.
I am not saying this study is compltely wrong, but some points made may be of little to no significance.
Example- engine oil contamination. That is a normal part of a healthy engine. ALL engines have some minimal amount of fuel contamination in the engine oil from ring leakage. So is this "wvo" contamination even an issue when factory recommended oil change intervals are followed?
If engine life is reduced, By how much? are we talking half or maybe only a few %? ANd once you get into high mileage engines maintenance history can not be overstated enough. So for example, if the expected engine life is 350,000 miles and it only lasts 275000 miles is that due to WVO or poor maintenance? What about the engine that only lasted 250,000 miles on diesel only?
Before ever making a business of this I personally had my injectors inspected every 30,000 miles, pulled my heads off at 60,000 miles and did regular Blackstone Oil Reports. I will have to do some digigng, but will post those results.(Hard drive crash a few years ago wiped out most of my early records and reports

) Maybe some of you who have been around a while can help me with some links to that stuff that is enevitably floating around on the web?
The injectors were better then expected, the pistons and valves did not have ANY buildup, let alone excessive buildup, and the Blackstone was perfect.
And okay, what if in general, WVO causes early engine failure. Lets do some quick math:
Being very conservative here: Say you only get 200,000 miles from an engine that should last 300,000. And half or 100,000 miles is on oil that you pay .25/gn to filter/collect etc. If you get 15mpg, for that 200,000 miles on oil you would have used 13,333 gallons of fuel. If you figure diesel at ~$2.75/gn (estimated average over last 5 years) that is
$36,666 spent in fuel!! Now say half of that was fuel that you only paid .25/gn for. Your new diesel bill is $18,331, WVO bill is $1,666 for a grand total of $19,975.50. Okay,
you just saved $16,960.50!! Again this is very conservative numbers. And making an inaacurate assumption that your diesel engine will only last 200,000 miles. More likely then not, savings will exceed $20,000.
Oh yeah- Emissions. Regardless of how incompletely it burns, WVO contains 0 sulfer and is 100% completely carbon nuetral.
Well I am late getting home, gotta run!

The Wife will wait, but the beer won't!
