WVO in both tanks?

Just thought of an idea that I was hoping to get some feedback on. I've been trying to come up with ways to cut down the warm up time on a grease car and then I thought, why not mix some grease in with the diesel in the main tank? I've heard about people without the grease car conversion who pour WVO into their tank with positive results, so would this make for the use of less diesel fuel during the warm up period? Thanks in advance

It would works.
Do some reseach on "WVO Blending" on the internet.
You can mix WVO with diesel or RUG (regular unleaded gas) in different ratio and put it in your
diesel tank to run as a one-tank greasecar system.
The ratio of blending would depends on the temp of the region that you are in.
If you are in a HOT region you don't really need a two-tank system.
The colder the temp the more diesel or RUG you would need (up to a certain limit).
I am in New York City. Other than the two-tank system I added a third tank (13 gal) with
WVO/RUG = 80%/20% for blending warm up. This ratio would cover my application here year round.
I don't bother to change the ratio (less RUG) in the summer.
I don't want to put WVO in my diesel tank. I prefer to use diesel to purge.

So you can run a rug/WVO mixture in a diesel engine? I always thought that you couldnt put gas in a diesel engine

never go over 30% gas

Yes.
As I said do some reseach on WVO Blending.

You can run lots of stuff in the tank. How long till it kills it is another story.

The veg oil will separate out in your diesel filter and you will end up starting your vehicle on cold veg oil.  My truck will barely start on cold veg oil even in the summer (when I forget to purge.)
Then the cold veggie oil will not make a nice spray pattern out of the injectors, you will gum up the cylinder walls and then, after a while, it is new engine time.
I hear lots about people's "successes" with blending but little about the failures.  I suspect the failures slink off and try to forget that they killed their engine with veg oil.  I met a guy four years ago  who was "one-tanking".  He was in the local newspaper, local tv showing his awesome, simple system- Just Add Veggie Oil!  Then one day, he had killed his nice new Duramax.  All the townspeople he encountered wanted to know how his veg oil truck was doing.  He said he wanted to crawl under a rock.  I took all his veg oil and filtering equipment off of him-bad memories for him.
I still use his barrels.

This is a touchy subject.
 
For me, it boils down to how I feel about my vehicle.
 
I have an 81 VW that gets nothing but veg in the summer and a blend as the colder weather dictates.
 
Currently, it is 100% diesel because winter is almost here.
 
I change the glow plugs out every two years because they get full of carbon.  This is a beater, so I do not care about it.
 
My 03 Super Duty Crew is a horse of a different color.  If I know I have a real long trip, then straight wvo in the main tank will not bother me at all in the summer.
 
I cannot prove or disprove why I feel this way but I feel that cold veggie in injectors is not a good thing.
 
I would not feel comfortable leaving veg sit in injectors for any prolonged period of time.
 
As I stated before (for me), it depends on how you feel about the vehicle and how said vehicle reacts to the veg.
 
My 2 cents.

 simple system- Just Add Veggie Oil!
That's simple enough to kill an engine!!!
It's all about temp, clean oil and complete combustion.
Looking forward to hear more BAD stories, one-tank or two-tank.

Bad one tank stories = Diesel secret, elesbet some other cheap conversions that just added a filter to stock d2 system.

Harold,
To try to answer your question about a "faster warm up time",  a few questions: (1) What is the car/truck - MB, Ford, Chevy ..?  (2) How long in time or distance does it take to get to engine operating temp?  (3) What city do you live in (climate).  (4) What is the temp when the engine reaches its operating temp - 180F, 190F?  (5) What is the engine thermostat rated at  i.e. 170F, 180F... ? Blending fuel is another game that some are successful and others not so succesful.  Clean, dry, hot VO and an engine at operating temp will not kill an engine, IP or injectors.  What WILL kill an engine is poorly cleaned oil, a cold engine, wet VO or cold VO.

Actually I haven't converted my car yet, but I plan on converting a 1983 Mercedes 300D within the next few months. I'm just trying to come up with some ways to make the warm up time more efficient so I can make sure this will work within the long term. I live outside of NYC so it can get pretty cold during the winter. 
So I guess it's safe to say then that this is too much of a gamble to be worth taking the risk?

Go for the two-tank system.
If your car take less than 10 minutes drive to warm up to operating temp you don't have
to go to that route.
My truck takes 20 mins drive to warm up.
Most cars take 5-7 mins only.
There is always a risk factor running on veggie!!!

Duly noted. If I'm going to spend this much money I might as well do it right and use the two tank system. Thank you for your input.

At the moment I have a tentative veggie supply. I work at a chinese food restaurant and I'm pretty sure my boss would give me his wvo, I just haven't asked yet. The are a few other places around if that falls through though.

Regarding blending:
We just purchased a Vanagon with 1.9 diesel that we had converted for a customer 5 years ago.  The previous owner never quite got the hang of purging correctly and eventully crapped up the stock diesel tank, fuel lines, etc, with polysnot.  The van runs fine when started on veg but quits running when on diesel or purge mode.  
Yesterday we went through the diesel system and found the fuel filter plugged.  After changing it out, the van still would not run in diesel mode.  I put a vacuum pump hose on the fuel line and sucked out wads and lumps of poly.    The banjo fitting at the diesel filter inlet was totally plugged with polysnot.
I am looking for a new fuel tank (or may cut this one open and try to save) but in the meantime I have "plumbed in" a 5 gallon gas can for clean diesel and the van runs fine.
This is what can happen with a steel tank filled with a diesel and veg blend.  
 
PS:  We no longer need our oil collection truck:      1989 Ford F250 with 7.3 IDI diesel.  Two tank VO system.  Very solid engine, starts and runs good in all weather.  Complete with 120 gallon vacuum tank, 40 foot suction hose with valves, etc.  Quiet, clean, dripless, and fast grease collection system for $2200.  Drive anywhere.
