Mixing svo and diesel (or any thinning solvent) is referred to commonly as "blending". There are so many variables including the paraffin content of the diesel fuel and the makeup of the svo/wvo I do not recommend this in most cases. The resulting blend may not be able to hold the VO in suspension if ambient temperatures drop resulting in a layer of VO covering the fuel pickup with a layer of diesel on top. Or in diesel fuel with a heavy paraffin load the blending of vo may cause the paraffin to drop out causing problems.

 

Also..when using a blend one usually does not have a separate purge fuel tank..and so the same problems can develop over time that occur with most "one tank conversions" due to starting and running a cold engine on VO.

 

Blending is even more experimental than using strait VO and no serious research has been done to develop a standard blend yet.

Does anybody know if you can blend wvo and diesel and some gas if it will work or will there be a problem down the road. And what about this DSE stuff has anybody used it yet and if so what result did you have.

 

 

   Thanks

Here is a link to a search of the Infopop SVO forum on Blending.

It is 29 pages long....so it may take a while to wade through. If you find any discussions that are really helpful...please post links or even just the URLs below.

and

 

Here is a link to the Blending section of the Fybrid forum...some info on DSE there as well. If you find really useful info..please pass it on here...a link o url I can index later.

 

and

 

Here search of the Infopop SVO forum on DSE.

10 pages long...

Again ..if you find any really useful posts please pass them on.

I will index and archive them for the next person who is looking for this info.

what do you think about blending inside the heated aux tank of a two tank system?  I have done it at times when I have run the tank to almost empty and still need a few gallons to get home and would prefer to run on the blend out of my aux tank than to run the few gallons of straight petro from my stock tank.  I found no ill effects, am I missing something?

I can't think of any reason that this might cause problems off the top of my head. as long as no high temp electrical heating components are installed pre-IP.  I will have to think about this a bit more. Any one else have possible reasons not to do this?

So, are you saying that it is not good to run regular diesel (or biodiesel) fuel through any electrically heated components?  I am getting ready to install injection line heaters, and was planning on turning them on while the car is warming up on diesel fuel.  Is it okay to run diesel fuel through heated components like injection line heaters?

I have injection line heaters on my 300 SD.  They are on while the glow plugs cycle and then I leave the heaters turned on while I drive with my WVO Blend containing K-1 and RUG.

 

So far, no problem.  Should I stop?

Diesel fuel loses lubricity when heated. But once it is past the IP I doubt that this will have any effect besides very slightly lowering the viscosity of the diesel.
 
So turning on injector line heaters with diesel fuel in the lines should not have any deleterious effects that I can imagine. Of course it does not have any positive effect either.

Evaluate this:
 A blend from a radiantly heated tank going forward through a HOH with no accessory heating unit ( Vegathurm) and on to the IP.
Does this sound workable ?
OR
A blend from an unheated tank going forward through a HOH with no accessory heating - - as above.

Both might be "workable" as far as fuel flowing and not damaging the IP if in a warm enough climate. But both ..and certainly the HOH will probably need a heated filter since it is
 likely that fats/hydrogenated wvo crystals will not be sufficiently melted enough to not clog the filter often.

Of course any blend likely also has the long term problems associated with cold starting on a blend.

One way to reduce  potential problems is to use 115v plug-in preheating to warm the engine and injector lines to  at least 68°F\20°C before starting.  Another way is to use a blend of no more than 25% VO.  I use both methods and always get clean starts with no smoke and immediate smooth running.  If the exhaust smokes and the engine runs rough on start-up, then it's likely that potentially damaging deposits are forming.

Hello group.. new to group.  Just starting my experience.  Currently running a 7.3 diesel 97 ford.. Collecting and running wvo blend.  Does anyone have experience/technical knowledge on the ability of the 7.3 to run blend?  My current blend is 37.5 wvo to 5rug and 7 diesel.. I was lead onto that by a fellow fuel enthusiast who ran his jeep liberty on blend.  Blend will vary in season.  

truck runs fine so far only 1000 miles or so to date.
