They are not the same. Commercial Biodiesel is made from virgin stock.

And that makes it better?

Properly filtered and dewatered oil is just as good as virgn oil if not better. Some "virgin" oils have not been degummed and would not be suitable for engine use.

Yes, it makes all the difference. The oil stock used to make biodiesel is processed and refined for the sole purpose of making fuel.
WVO was NEVER intended to become fuel. It was made to cook food in.

I currently use B20 biodiesel as my fuel. However, I would never let anyone within 100ft of my car with a bucket of WVO.

Have some salad, Forced Induction...

Politics are not welcome in my threads.

This thread is due to the mass of calls during the last two weeks.
All new owners who thought they could pump WVO from a grease trap into their tank without filtering or dewatering...

Sludge choked tank, plugged tank strainer, filters, and/or wrecked injection pumps are the end result.

One customer reported his 300D fuel tank capacity was eleven gallons, because of massive sludge/fat buildup.

Ask Ford PSD owners. Their common rail system is even dead headed and some kit manufacturers design a fix for Ford's screw-up. The Cummins 3rd gen CRD is now being converted. While there is no long term effects due to lower miles on the Dodges being converted. The Ford PSD has logged many many miles on wvo. The engine in the Liberty wasn't built by Chrysler. It is built by VM Morori in Italy. A version of the engine is used from utility applications to marine applications. I'm not worried about the injectors... I'm worried about the parts Chrysler bolted up to it!

So, if a set of injectors lasts only 100k miles on wvo versus 200k using #2 dino-diesel... Lets do the math... 100K miles / 20 mpg = about 5000 gallons of fuel X $3/gallon = $15000 That would be a pretty dang expensive set of injectors! Even if, it worked out to be a break even [doubt it] for me, advancing alternative fuel use is the goal. Lets say 50K miles the injectors crap out. True wvo costs are around 10 cents a gallon not counting the taxes - yeah yeah - that topic has already been over discussed elsewhere. Lets call it a buck a gallon... Do the math... That still leaves around $5000 for FOUR injectors. I'll take that chance.

I will... for start up and shut down. Because, as you have stated, the engine was originally designed to burn #2 dino. That however, because of the beauty of the type of combustion engine it is, makes it a "flex-fuel" vehicle.

There are lots of folks doing great research using these old MB's. I would have never bought the old crap-box if I wasn't going to use alternative fuels. I'd just buy a fuel efficient Honda if all I wanted to do was save money and dispose of it every 5-7 years like half of the population in the U.S. does now!

Ahh..

That is precisely why svo/wvo use will never hit mainstream. Too many folks think all they have to do is dump a can of Crisco in the tank and away they go!!

It's also why we must get out the message to do it right. If not, more people will be joining the WVO fad and keep killing these wonderful cars with such simple mistakes. It's just saddening to see a car survive for 22+ years only to be thrown away by somebody just wanting to pinch a few pennies.

There is too much misinformation going around the web and TV about biofuels. It's important to keep the facts straight.

Truth. Even though my car wears "WINGAS" vanity plates, I've not yet run any WVO through it, nor, I think , will I, since I don't have any space for a filtration system yet. I've become filtration "anal". And its not the Injectors I worry about in these cars, .. heck they're easy... its the OEM IPs. They ain't.

For now, best I can hope for is a few 55 gal drums of bio100 made from chicken wing grease! And I'll have to steal them !

And non-wvo folks, its not just about pinching a penny, heck 35 mpg combined on dino diesel does that, its about getting one vehicle in the family off gasoline. Into a renewable.

Canadians can sure cook oil out of dirt, and invented canola, which has a high oil yield per bushel!

But I'm not sure I really want the rest of the US switching to diesel, or biod.! Not until supply is endless! From home grown beans!

The point of this thread was to address the need to properly filter (and additionally dewater) your waste vegetable oil prior to use in a diesel.

Why does the intent matter? Why does the source matter?

What matters is that it works and works well given that the oil is filtered and dewatered

Intent and source matter greatly because there are alot of uninformed people throwing around the "Biodiesel" name when they really mean WVO or SVO.

Biodiesel (even B100) is a completely different substance from waste fryer oil and cooking oil off the shelf.

Hello Everyone

Hey ! That one system at your link above looks just like mine.

It looks allot like mine.

O yea, it is mine.

Have Fun Everyone

PS: I agree with the need for filtering your fuel.
(diesel, bioDiesel, WVO, SVO ..etc, all fuels need filtering)

I also think we may need a new sub forum to help with what was so nicely called " politics " earlier.

Thanks again.

It is that deep, dark, secret place, called Open Discussion.

No, much of the commercial biodiesel is made from WVO. Both of the biodiesel plants within 30 miles of me are using WVO. One of them is getting oil from the same kitchen that I am. (but I get first dibbs )

By the way, with a proper conversion and properly de-watered and filtered WVO, most diesel engines will last LONGER on WVO than on #2 Diesel.

Shame there is not enough WVO to run all of the cars and trucks in the US.

You are exactly right! I am always in competition with the big bio diesel plant for the WVO.
