I have posted before about my experiments with used engine oil or used motor oil. It works but it was not confidence inspiring.

For one thing used motor oil is a nasty material, toxic, carcinogenic. It is loaded with heavy metals and fractured hydrocarbon byproducts.

My last attempt left me convinced that I would have to mix 50/50 with RUG or maybe even more RUG and there go any $aving$. It is cheaper, cleaner and more fun to run veg oil.

The attraction was the same for me, unlimited supply. Many garages burn it for heat.

Back to the original topic.....1 gal RUG to 4 gal WVO.

Sounds like you have to go by just how your car acts? Seems some have a knocking problem with the 20% mix. If thats the case what can you add to thin out the WVO? Seems like the tiny bit of alcohol would not be enough for thinning but would help combustion. I would think you would need the proper viscosity so your nozzles are spraying the right pattern if you will.

And with the RUG mix, what quantity of cetane boost. Seems I've been told like 6 oz. per tank. Or maybe the 6 oz. was for 5 galllons.

Not wanting to go through the trouble/expense ,not to mention taking up room, of a 2 tank system, will the 20% mix congeal in colder temps? I was wanting to do a test in my fridge but the wife is against that. I would think not but would rather hear from someone who has experience in colder climates. Someone did mention they had no problems down to 16 degrees but I would like to hear from more than one source.

Thanks a ton for the info. Once I get up and running on WVO I will be sure and report to possibly help someone else.

Cheers,

Bill

It seem the consensus of 4 gal of Used Veg oil to 1 gal of regular unleaded gas. Or any better ratio?

Another question is where is a good place to buy the filter net ( 10 micron or lower?) A while ago I came across one outfit sells the for few bucks a bag, and re-washable too.

Is super brilliant discovery to do away with heating and separate tanks, back flushing it too.

TIA.

If u have a link of the filter web site and better mix ratio or ingredients please feel free email to bc8163892@yahoo.com

I'm going to try run in my 78 240D 4 spd.

Someone mentioned using a folded over bed sheet or a pillow case for filtering. Seems as though i remember they took a piece of chicken wire and made a cone out of it to fit their barrel then placed the sheet or pillow case inside of the wire. Sounds good to me. I would think the cloth is certainly fine enough.

Cheers,

Bill

My experience is that 4 gallons of WVO and 1 gallon of RUG is just plain wrong. That is just too much gasoline for a diesel engine in warm weather. I tried that combination once last summer and will not do it again. My 300D just didn't like it, it had difficulty idleing with the AC on and it had a bad vib under hard acceration. Even under normal suburban driving I do, mostly 45 to 60 mph, it had a bad, uncomfortable throb. If your engine is letting you know it has discomfort with the fuel, I'd say watch out. I then went 2 quarts to 5 gallons. Again on my engine, it feels like too much, especially on hard, (WOT) acceleration. So about mid season last year I settled on this simple formula of 1 quart per cube, (4 1/3 gallons). You have to drive it to believe it. Smooth and really willing to go. Zero to 60 time about a second slower. So performance is down just slightly, but the sound and feel of it is so good. And I think that sound and feel are very important - I just don't want any strange noise or vibes coming from my 617. I did pick this formula up from another writer on this forum but I haven't heard from him on this thread.

20%RUG is too much for some some and max for others. If 20% is too much use K1, #2diesel, Jet-A, Naptha or Coleman lantern fuel to make up the rest. Nothing says you have to run 80% WVO. Try it in smaller quantities first. Hell, when I first tried it, I worked my way up from 20%wvo / 80%#2. I'm thinking I like my current winter blend and the cost savings is still substantial at 50%.
Experimenting is part of the learning curve. Start out slow and see how it goes. I'm sure in no time you'll want to run higher percentages. Depending on your blend, cetane boost can be optional, especially in warm weather. The amount you use also depends on what type of cetane boost your using. Amsoil is almost 100% 2EHN so you need less to raise the cetane number rating. Again,IMO it's better to run less wvo and more solvents, to keep the viscosity at least to Schur ecofuel standards. I'm wating to get E85 to use in a blend at 5%.

The hardest part is finding good oil, getting it home, a place to process it then getting it in the car.

It sure is! ...The Benz has over 12,000 miles on its (clear glass) primary filter, running Rug/Wvo blends using that simple filtering method. The primary filter still looks new. I may clean it at 25,000

I don't get it.
What kind of knuckleheads would filter smelly cooking oil in a bedsheet through chickenwire and use it instead of $4.00/ gallon diesel fuel????

And just one final word about the wax issue.

I have read that some people on the west coast (where the paraffin based additives predominate) will swish acetone around in their tanks when cleaning them in order to remove the wax build up.
So, it is not only an issue that arises from WVO blending.

I have heard of people adding acetone in with their diesel, also in their WVO. That may keep it from precipitating out. I haven't done any tests, or read any though.

Matt, whats your view on acetone? I would think that after years of running diesel in my car there is a substantial amount of wax built up.

I guess the thing to do is carry filters and the necessary tools to change it with you and, sooner or later, all the built up wax will come out.

My home heating oil guy says that the RUG mixed with the WVO will keep the wax melted and your filters won't get clogged. My question[s] is is a quart enough in 5 gallons to do that and is that correct info?

Got the 240 running and on the road again so I guess I'll be trying the WVO soon as I get the formula right. I am going to do a diesel/WVO blend. Kinda scared and kinda can't wait.

Cheers,

Bill

Kind of another topic here but.....what is the best/easiest way to dewater?

Thanks.

Cheers,

Bill

Bill;
The standard blend is: 4 gallons WVO: 1 gallon RUG; 2 oz of PS Cetane Boost & 1-2 oz of Acetone.
If you want to try this and see how your 240 responds to it, and adjust from there. Maybe less RUG after that ; maybe if necessary add a little Diesel to the RUG blend....after that....It takes some time to see what works best for you car.

"..I'll take a simple "C" to "G" and feel brand new about it..."

In a WVO and RUG blend, there should be no wax at all except for what was already in your tank. Or is that what you're talking about?

I've heard that the standard spin-on filter acts as a water separator, but I wouldn't bet the farm on it without actual data.

You can install a water filter, or you can settle the water out of the oil (which takes at least a week), or you can boil it out (which uses more fossil energy).
