Don, you're talking about subpar biodiesel, he was talking about running WVO blends.

Judging by the sound of the engine, it digs the stuff.

I'm not interested in wading into this silly debate (again), but if your engine will not run correctly petro diesel, you have something else going on that should be diagnosed and corrected (injectors, IP timing, something?). You are simply masking a problem with the different (slower) combustion characteristic of BD. If you correct this problem, you may find it runs better, regardless of fuel.

Then DONT.

There are a lot of people that come here looking for answers. A lot of these people are newbies that found out about WVO/Bio et al and want more information. To them it is not a silly debate. If you do think it is silly, then dont even read it. IS that really so difficult??? At one time you were a newbie too.

I believe the original poster was asking about other peoples experience with WVO (though I would have used another title as to not raise the ire of some people).

Me:
1800 Miles on WVO with 5% RUG added - NO issues, unless you count replacing two glow plugs an issue.
WVO, filtered 3 times through double 5 micron filters.
Naturally dewatered via heating from the sun (will not do this in winter, but heck it has been around 100 degrees for a while)
Oil Sources: Mainly Canola, some soy -- Soy freezes at a lower temp I have found.

I was simply trying to point out that WINGAS should find out why his car will not run correctly on diesel fuel. It obviously has a problem that should be corrected before it causes damage, regardless of his fuel.

I made no comment about the advisability of using BD or WVO. Frankly, I'm bored with the whole "silly" debate, everyone has heard it over and over and should have enough information to make up their own minds.

If you are tired of it, dont read it! My point (again) is that there are plenty of new people here looking for information and it is all new to them.

And I suppose going out on your free time, collecting, transporting, filtering, treating, storing, and filling your vehicle by hand with nasty used grease is considered "readily available"?

Depends on who you talk to. Not everybody has the same values or priorities. My priority might be best price and your's might be environment and somebody else might be color of the fuel.

Well, that again depends on who you talk to. Somebody that cares so much about the environment that they consider this a little inconvenience and are willing to do it might say it is readily available. You or I might not.

What is the savings AFTER you factor in time, space for storage, taxes, etc, etc? Otherwise, you are comparing apples to oranges.

I'll bite. Why?

The only negative is that in the last 6 months or so I have to keep my foot on the throttle slightly at startup to keep it from stalling. This is for only about 30 seconds, then it smoothes out.

I think that spells bad news. You should perform a compression test to see what numbers you are getting. Also, pull your injectors and heat shield washers to see if you have any coking from glycerine residue. Just a thought.

I don't know about his engine but mine, 606 has a prechamber and that has slits on it that might get crud on it and mess up atomization. If I were going that far, I'll pull the prechambers too.

I'm really not trying to interfere with your evangelizing, I was just trying to give WINGAS some advice that had absolutely nothing to do with fuel.

I'm sorry that his post happened to be in a WVO tread, I normally wouldn't have bothered posting to it.

Look at the cost of milk thanks to the Flex Fuel fad and the cost of corn going up. Make gassers run on pure methanol or ethanol instead of RUG. I know, milk prices will go up higher.

I do live out in the sticks and see new developments moving in. I would rather see what was once a field become a field again for renewable fuels instead of being sold off to yet another developer. Out here we have more empty houses, and they keep building new ones.

I dont think ethanol is the way to go. Id rather seen corn turn to corn oil instead, the original intention for the diesel engine

The US wastes enough corn as it is. If they want to grow more oil bearing plants, then why dont the farners that are getting govt paid to not grow their crops just grow oil plants then?

Maybe some of the alternative fuel proponents would have more success on here if they didn't always come here with a chip on their shoulder.

Since that does not seem likely to change anytime soon, I think we ought to reconsider the idea of a separate forum for alternative fuel discussions. That way the alternative fuel proponents would be able to Bullshoi each other to their hearts content, and the Mercedesshop Diesel Forum might eventually return to the outstanding level of quality and fellowship which it was once famous for.

If your looking to save money. Owning a benz isnt the way to do it. With the attention they need they arent cheap to run, if you run them into the ground then they can be! But you wont get far with that.

If your going to mix veggie and diesel i still dont think its the way to go for saving money unless you plan on investing on a engine rebuild. It took nearly a year for my compression to drop and for injection components to get coked up. Here is what my injectors looked like after running wvo/diesel blends...

EDIT: this was from my 83 300SD which i no longer own

Properly dewatered, filtered down to 1 micron, majority was canola oil. In the end id recommend against wvo blending. Everyone has their own veiws on it but from my experiance either 2 tank kit or buy/make biodiesel if you want to run alternative fuels. Ive been far to busy and cant collect oil to make biodiesel anymore. And my mind is set on buying biodiesel at the pump.

I dont mind spending the extra cash for biodiesel if i can get it locally. But as far as saving money, forget that benz and buy a honda or toyota. It would suit you better.
