Also proper de-watering removes most of the acids along with the water in most of the oil sources that I have used over the last 30 years.

But there is no way to really tell if you have infact removed all the acid from the WVO without sending a sample to a lab each time.

and while it is not a Mercedes,( but it is German, and diesel) and not specifically for USED cooking oil, here we have a factory built, two tank equipped plant oil burning farm tractor. complete with warranty from the manufacturer. I really doubt they would market this if they thought it was going to cost them millions in warranty work(replacing IP's and engines)

it is only a matter of time before auto makers follow suit(lets hope). then all we need to do is get past our lovely emission regulations for the USA.

peace, grease and goodwill towards others..............

that tractor engine was designed to run on WVO. Mercedes engine are not.

My brother (ROLLGUY) And I have a combined 100,000+ miles on straight WVO and WVO/RUG blends with no fuel related failures. We only use clean and dry oil and NEVER use any PHO or animal fats.
The only negative I can see is more frequent fuel filter and oil changes, which are more than offset by the fuel savings.
I too have never seen evidence of a (veggie) fuel related engine failure and I am not at all worried about any of my diesel engines getting damaged by the fuel I put in the tank. I would be more worried filling up at the gas station after it rains.
My OPINION about WVO is based on personal experience, not hearsay.......Dennis

Who started the rumor about acid in wvo? Some people will say anything to stop veggie use. As for the farm tractor, does anyone think they used different metals in the engine. NO! Just two fuel tanks.
I say, lets help each other keep our Mercedes on the road, and go to another forum to talk about fuels.

To my knowledge, by the way, acid is only a problem with wet oil. If it's properly dehydrated, there's no water for the acid to dissolve into, so no acid erosion. I could be wrong, I don't have any specific sources to back that up, but that's what I believe to be correct.

This concern over fatty acids has me confused as well. In chemistry class, it was all about proton donors (acids) and proton acceptors (bases) which did their business in aqueous solution. If you have a fat chain that's a proton donor, does it only dissociate in the presence of water, or does it interact with iron and prime it to interact with any free oxygen in the presence of oil only?

Well, I'm sorry to say I cannot answer your question, moon, but seeing as I am currently taking chemistry, I shall pose the question to my teacher. Then we'll have a PhD reference. I will post my findings on this thread, but I also have to agree with Ryan, this problem should be under another forum, maybe start one on this website?

I have seen 6 benz engine failures
4 were n/a motors running lovecraft kits
the two others were run without motor oil

i have seen many injection pump failures
evenly spread between veg ,biod and dino diesel users

what experience do you have mr. 79mercy

biodiesel eats your fuel lines and will repeatedly clog your filters
if you have a older car. this is due to sediment build up being washed off the walls inside your tank fro the lye in bioD

biodiesel also takes large amounts of energy to be refined and have
meth and lye byproduct
and its usually not cheep

the diesel we have in so cal if low sulfer content diesel
and it is complete **** compaired to bio or veg imho

Total acid number testing can be done in the field and isn't needed for every batch as long as it's low enough and your source doesn't change much. It's not enough of a problem to worry about other than an ocasional test.

I lost track of how many 100's of thousands of miles I have driven on WVO a couple of decades ago. I always use clean and dry oil and ALWAYS

use the PHO and animal fats.

I have NEVER had to replace a WVO filter but have a few times been forced to replace the diesel filters. I do change my oil more often than I would with diesel fuel but still go over 5000 miles with Rotella synthetic.

This is with properly heated two tanks systems.

The love craft kits are a horrifying / worthless kit. That is one kit that as a grease kit installer that I will not install on any clients car or truck. If you install a solid well build kit you’re going to be fine. You have simply rules that you need to follow if you plan on burning wvo as a fuel. Fallow them and your fine.

The biodiesel issue with clogged filters is like seeing / believing in ghosts. I’ve personally been driving on B99 for 5 years and I have never clogged a filter. However, I have seen this problem on very old cars, but it only happens ONCE, and the dirt / slim is removed from the system and that is that. When you feel a power loss just replace your filter once and your fine. And yes, high percents of biodiesel B100 will eat away at your fuel lines very slowly, but simply upgrading them to a biodiesel fuel line will fix the problem. Once you upgrade to a biodiesel rates hose, your good for the life of your car. Those hoses last much longer on biodiesel or diesel.

To your comment about biodiesel having a by product of meth and lye. This is not completely true. You can re-capture your meth after you are done making the biodiesel but the lye is used up the process. Plus the wvo you use to make the biodiesel is from a plant base system. That puts oxygen into our earth. Diesel dumps tons of nasty harmful gasses on our earth. Biodiesel can be cheap if you want to make it yourself or join a coop. But yes it is normally more expensive then normal diesel. Because quality products normally cost more. Your on a MB forum. So you understand that quality is going to cost more.

The low sulfur diesel is good for the environment, but it has less lubricating factors and will damage IP that aren’t designed for it. So adding some biodiesel to your diesel tank will fix that problem.

I agree

Properly made biodiesel does not contain methyl alcohol or lye. My experience with WVO in 23-year- old Mercedes was repeated clogging of the primary filter (many times) that tapered off as the slime from years of #2 diesel got cleaned out of the system. Steve
