I agree. Even when thinned out (blended) VO smells and feels different from actual BioDiesel.

What is their reason?

Couldn't be a good one, he is keeping LOTS of repair work out of his shop!

I replaced all fuel lines and removed, pressure washed and flushed my tank and cleaned the tank strainer and fuel sending unit before running any BD and thus far have had no gunk at all flowing into the primary with B100 for the past 600 miles.
I have 47k use of BD in my TDI with zero problems all on homebrew BD.
BD is why I now am a 3 diesel household with more to come.

bio or wvo WILL break loose all the sludge in your tank/ lines. flush the tank, clean tank filter and replace the rubber lines. Being cheap, I run a mix of WVO (dewatered and filtered) and reg diesel 50/50. Someday I plan to convert to dual WVO/diesel, untill then I have replaced the small pre-filter with two old timey lawnmower type (clear plastic) gas filters run in parrallel and change when I see the paper start to collapse from the suction or when engine starts to loose power. Also installed a water seperating filter and an electric fuel pump under hood to prime when I change filters. Pump is probably not needed but handy if you run out of fuel, especially on my 350 with no mechanical primer. The injectors will gum up but I clean and set my own about every 20,000 mi. A friend who rebuilds IP's says he has seen pumps get whacky and are hard to calibrate after run on BIO from certain places. From all I have heard the dual WVO/reg diesel system is the best. System should be flushed with reg diesel on shut down to prevent guming up the works--especially if the car sets alot between startups.

The shop says that biodiesel and WVO ruins cars and that Bosch will not rebuild the injectors if it has been run. Also, "it smells worse than dino diesel" and "it's bad for the environment because it leaves carbon and it causes more pollution to make than it's worth, it makes the price of food go up, it causes people to lose jobs, global warming is a hoax, homemade biodiesel is dangerous and you are putting your neighbors' lives in danger when you make it, and people are only doing it to boost their egos and so they can feel good about themselves, that's all it is--to give them a warm fuzzy feeling inside that is actually causing more harm to the earth than if they just kept using dino diesel".

I got the run down when I mentioned biodiesel. I take a lot of crap about it by people who are trying to make me feel guilty for trying to make a difference in the world. But why would anyone want to try? If you are perfect in this world they will put you on a cross.

Sea Foam is fine for a one time purge but do not use it all the time the Alcohol and chems will scour the IP barrels. Better to use a injector cleaner specifically made for diesels.

Not sure I disagree with their points in reference to BIO. WVO however is a waste oil, either gets dumped or picked up and turned into BIO or barge oil for ocean liners, Barge Oil burns a whole lot dirtier in and ocean liner than WVO in yiour car. Never heard of Bosch not rebuilding iinjectors, possible but I clean and set my own and there are a lot of MB injectors at Pull a part for a few bucks each. Anybody who owns an old MB diesel is should either be rich or do their own work. If your rich, burn reg diesel!

Diesel Purge by Lubro Molly is a good one to use.

Smell is an objective thing.Biodiesel is carbon neutral or much closer than dino.

Dino diesel at 4.50 a gallon
is what made food prices go up.

this is too hilarious to even respond to.
The world is flat True.. it is dangerous.. be careful please. Go buy a prius.

Eric Cartman hates hippies too..Peace ,love,spirit of woodstock..blacklights bong-hits, innagoddadavida..

yup +1 on that..

Me thinks there are similar political motivations at my shop. They don't directly say it, but the 2 times I've mentioned biodiesel, they clam up and take an angry tone. And I hear you about the guilt... honestly, there is no perfect solution for anything, but if you want to make a difference, you HAVE to start somewhere. People that say "well, it just is what it is!" and don't do a damn thing are the ones that are a part of the problem.

A lot of the arguements people make against biodiesel are the arguements made against ethanol. And those arguements don't work against biodiesel. Right now it takes more engery to produce ethanol than you get out of it. That is not the case with biodiesel.

The BioD I use is professionally manufactured from WVO by a local businessman who buys the WVO from local businesses.

Local restaurants buy the oil, then make a profit from the food they fry it in, then reclaim some of the original cost of the oil by reselling it, then the local brewer makes a profit off of his refined product. So after the initial cost to the restaurant (which is partially offset by reselling the oil), all the $$ stay right here in my community.
