Question Try again: Help fm a Techie; WVO & Kero combo; good or not

Any techies know if running a mix of 80% wvo & 20% kerosene is OK to do w/o any modifications to an '85 300D-T?
Will it harm any lines; IP; seals or etc?

Someone is doing this a short while so far on his 300sd...

I ran a search and found that I have posted to 18 threads with the word blend in them, this is #19. I really can't think of anything else I want to say on the subject. I have also already posted everything I want to say on the board linked to in your first thread on this subject. The repetitive conversational use of this board to rehash the same topics over and over is a major reason why searching is less useful as time goes on. Please keep your conversation to your original thread and previous threads on the subject.

80% WVO & 20% Kerosene

I am not trying to be rude or mean and I would like to help you but you have to help also. If you do not want to put any more effort into this than to have it all spoonfed to you it is probably not something that you want to pursue.

Mr. TK:
I think alot of people misunderstand I was asking a specific question on what the technical effect if any this mix would have on the car....and couldn't find this answered on any of the threads when searched blends or kero /wvo . which I spent plenty of time doing...( so chill on the attitude..) that's why I asked it a few times....
mspee is doing it on his mb; and I will too. maybe with diesel instead of kero; this is a great site; but I guess .'the proof of the pudding , is in the eating..." on this one.

I don't think anybody can say for certain running anything other than "normal" diesel is ok for these cars. There is a growing body of evidence that it doesn't seem to hurt anything, but asking if anybody knows for sure is a waste of time. There are dozens of WVO-related websites out there that could probably give you more information than this site; you should try posting your question to some of them.

Not a techie but...

... research and experience. I agree there is no definative answer- this whole field remains experimental. Here's an update on what I'm experiencing with blending, and why I do it the way I do based on what i have read-
-Climate is everything. Living where I do, I've not been able to successfully go over 30% WVO / 70% Diesel. Even though we're getting 80 degree daytime temps occasionally, it still drops to 50 overnight, and my morning cold starts are downright nasty with 30% WVO (serious knock and smoke until engine reaches 100 degrees). After it warms up, the engine gets very smooth and quiet, with no smoke or knock and plenty of power. However, I do get some knock that's bad enough to worry me if I go back to 100% Diesel. This problem started before I started using WVO. I'm going to get my injectors bench tested and replaced if necessary.
-Diesel Fuel wax separation- I still put in a quart of Naptha for every 5 gallons of WVO, as a safeguard against the WVO causing wax to separate from the #2 Diesel. (Based on something I read- this may be cheap insurance against a nasty situation)
-WVO quality... the WVO will still contain sugar and other disolved food substances no matter how well you filter it. Some say this will cause a buildup of polymers on injectors and piston rings over time. This problem is obviously not unique to blending- in fact, I would think it would be a far greater risk to those who run 100% heated WVO.
-I might try a far heavier WVO blend the next time I take a long day trip- once the car is fully warmed up, and I'm certain it's going to remain a hot day, I would pour in the WVO to 80 / 20, and then make sure I re-fill the tank with Diesel when I arrive home at night to ensure a safe cold start the next morning.

In a tropical climate like Florida you can probably get away with almost straight WVO. An inline electric heater like the one offered by Neoteric Biofuels installed right before the IP would be cheap insurance that the WVO is hot enough. Simply turn on heater and wait a few seconds, etc. for it to heat up the fuel in the line, then cycle the plugs and start the car. The heated WVO/fuel would quickly enter the IP and heat it up. I would even be tempted to install an oil pan heater on the exterior of the IP for "winter" morning starts. There appears to be great success in blending in warm climates yet there are no guarantees. So become a guinea pig or watch from the sidelines. RT

Don't waste your money blending kero with WVO. Kero is just one step above, has slightly less lubricity, and is usually noticably more expensive than Diesel. Diesel also has slightly more BTU per pound, i.e. power, than kero. Certainly if you can get kero free it is by all means worth the effort, but as a rule I wouldn't bother.

Cool 1 tank or 2

I am ready to start this. I've read enough. Do you think 1 tank system will be ok in hot south Florida? Next stop wvo searchh at chineese take out!!
As soon as I'm filtered I will add straight wvo to the tank...and whatever diesel fuel is in there at the time.

The only changes I made to burn WVO was to,,,

Turn up the idle a bit. I was having to drive with two feet until the car warmed up. (Stall at idle).

Now She doesn't stall at idle when she's cold.

80/20 WVO to (kero or diesel) Haven't see much difference between kero and diesel when I blend.

Someone is doing this a short while so far on his 300sd...

When you buy diesel in the winter months, all that is done to lower the gelling point, is they add kreo. Diesel rated to zero degrees is a 25% blend, -20 degrees is a 50% blend and -40 diesel is straight kero. Kero should solve the wax problem with no other additives. Regular old kero has sulfer in it, that gives combustion a little kick. I think that is why some of you see an increase in power on wvo. Moderen diesel is doctered down for the tree huggers. LSD stands for Low Sulfer Diesel. They take all the good stuff out. If you doubt me go to your local farmer and get some off-road diesel aka #2 fuel oil or home heating oil. A marina should have it to for the sailboats. I would be fibbing if I said I haven't done it in my own car. Your power will go up so will your mpg. I can't speek for the rest of you, but here in the northeast kero is about $1.80 a gal. RUG 2.55 a gal. Acetone is about $3.50 a gal. Power Service is 5.50 a quart. Do the math kero is cheaper then a rug blend. Diesel is about $2.65 a gal __________________

Are you saying that Sulphur content provides additional power from the diesel?
Are you saying that Used Cooking Oil has Sulphur in it?

AFAIK, Sulphur is taken out to reduce the amount of SO2 in the exhaust and ACID RAIN which it causes. There are lubrication issues with ULSD, but I have not yet heard anything to support your statement that the reduction in sulphur reduces the power output of the diesel engine running LSD.

[QUOTE=TonyFromWestOz]Are you saying that Sulphur content provides additional power from the diesel?

I don't know if tho cooking oil has sulphur in it. I was just guessing on that one. Does anyone know if it does? I forget exactly how the sulpher affects combustion. I can do some digging (when I get the time) to find out. I can tell you it is not good. The refinery does reduce the sulpher in diesel, among other things. This is why all heating oil aka off road diesel has red dye in it now. They want their eco friendly diesel on the road also so big brother can catch you cheating the diesel tax man. I can get you the spec sheet and see what the content is. Try the #2 fuel oil and see for yourself. Working for a fuel delivery company, I have tried just about every sorce of fuel there is. Including Jet-A which just is doctered up kero. Thats right some of the most powerful engines on the planet run on kero. #2 fuel oil has given me the best results for mpg and power.
