Oh im sure it is, but i was just saying it poured very quickly and thin like the biodiesel. Not saying it was the same viscosity as biodiesel im sure it still is thicker.

Why heat it when you can thin it out with gas? 20K miles on 2 different benz's

The 2 main ones used in Schur ecofuel, were Isopropyl(99%) and butanol. You could also use methanol or ethanol @ 5% but because of the extra octane value offsetting the cetane value. A cetane boost of 3 - 5 numbers may be needed. Again it all depends on the engines condition. The higher the alcohol the better, but not neccessary.

Schur ecofuel= 80% Rapeseed oil/15%gasoline/5% alcohol

In the viscosity table....
Raps raffinate= Rapeseed oil (canola oil)
RME = Rapeseed methylester (biodiesel)

You have to say at what ambient and quantify "way" Look at the viscosity table. 100% biodiesel is 8 mm2/sec @10c
70/30 blend @ 40C is 10
Also, Schur ecofuel is still liquid @ -25c Biodiesel would be
frozen.

Man it's an interesting thread but I dunno...blending sounds just too good to be true...and I have to argue that last point about melting points. I figure that biodiesel methods are pretty sound as general rules here apply...different source oils will lead to differing results, melting points are one such differing result. The base wvo I use stays liquid down to 16^F...-10 C?? or so...not sure of that conversion right off the top but the point is that if you start out with a good oil like what I am getting your biodiesel product should exceed the melting point of the base oil prior to transesterfication. -25^C is not out of reach for good base oil. In fact I am sure my base oil will remain liquid below the 16^ as stated but this is as cold as it ever got here over the winter so go figure...it was a warm winter but my arguement remains. I firmly believe that producing biodiesel from a good stock, base oil, and through good processing practices is the smarter way to travel when it comes to alternative fuels...heated vo/wvo systems aside. If you want to fuel your benz with an un-heated fuel and pretend it's as good as diesel then I persist in saying that your safest choice is to find a good oil stock, transesterfy it, wash it, dry it and try to improve on the basic theory. Blending seems to me to be just a dangerous shortcut and it still leaves all that crap that biodiesel removes to be injested in your motor...nasty stuff drops out of biodiesel and stays in the bucket ya know??...but that is just my opinion and I certainly, most definately...could be, might be wrong.

My biggest concern with biodiesel was working with methanol. If you are damaging your optic nerve you won't know until it is too late.

My blend is a lot less work with less scary chemicals and it runs my car at lower temperatures than I expected. I would have to look back to see if I could find it but I want to say I have run on 16F mornings. I use no fuel heat on my car.

Now to jump the fence, my fuel costs are about the same as someone getting 50mpg on RUG, not unheard of. That approach would be less work still, less mucking in veg oil and changing filters. My exhaust wouldn't have as cool a smell.

I'm glad this topic came up but I take it there is no clear concise answer to the original question. Eveyone has their own opinions it seems leaving me still confused.

I have read several studies on WVO versus diesel and it seems that in the short run it is ok but in the long haul you risk catastrophic engine failure due to crank case oil contamination from the WVO.

I have been told that the wax will seperate from the diesel by using WVO but by mixing in RUG with the WVO it will eliminate the wax fear because the RUG melts the wax.

But the crank case oil contamination issue still remains. Any comments?

Thanks.

Cheers,

Bill

My only question is how cold does it have to be to get wax from mixing diesel and WVO? Change your oil when you should and I would not think you should get containinated oil.

You could do a test using your fridge and a small quantity of mix.

Here is some reading for you regarding crankcase contamination:

From the above site:

Running on veg oil is a far more established practice in Europe than it is here due to the higher fuel taxes. They have been paying over $4/gal for years.

In our cars the fuel is injected into the precombustion chamber. We also have a deep centrally located combustion chamber. These features make it unlikely that liquid veg oil will ever reach the walls of the cylinder where it could cause problems like carbon fouled rings or lube oil contamination.

I remember reading about lube oil contamination but don't remember any specifics. I just remember that I wasn't concerned about it. 61x MB engines are a good match for veg oil.

I only see 1 reference to ccc (Engler et al. (1983) This study was not blending. The way I read it. They were running cold neat oils. Worst of all, they used raw oil ungummed, unwaxed and possibly unfiltered! I also find this statement odd; "Engine performance tests for processed vegetable oils produced results slightly better than similar tests for diesel fuel." The energy content of diesel is higher than plant oils

Engelman et al. (1978)
They concluded that waste soybean oil could be used as a diesel fuel extender with no engine modifications.

Wagner and Peterson (1982) reported mixed results when using rapeseed oil as a substitute fuel. Attempts to heat the oil fuel mixture prior to combustion exhibited no measurable improvement in fuel injection. Severe engine damage was noted during short-term engine testing due to the use of rapeseed oil. A long-term test using a 70% rapeseed, diesel fuel blend was successful for 850 hours with no apparent signs of wear, contamination of lubricating oil, or loss of power.

Van der Walt and Hugo (1981) examined the long-term effects of using sunflower oil as a diesel fuel replacement in direct and indirect injected diesel engines. Indirect injected diesel engines were run for over 2000 hours using de-gummed, filtered sunflower oil with no adverse effects.

BTW all these tests using tractors or DI engines, bare little useable data for IDI road driven MB's.

good stuff! I'm looking to join the club. my pockets are indented.

Can you run a small concentration of used motor oil ?


Can you use motor oil ?

What's different about ATF that it can be used safely and not motor oil ?

You can, it just produces a LOT of smoke, even in small quantity, plus it probably has metal particles and junk in it from the engine that filtration won't get out, and that will just add severe wear to the injectors and injection pump....so its best to avoid using it.
