hi guys

did anyone experiment with blending wvo so getting viscosity
same or close to diesel viscosity?

average outside temp is 70F/20C,..say ... 80% wvo 20% gasoline... is it too much gasoline in mixture?

IMHO gasoline is better thinner than diesel...but how much is
...too much?


thanks
ChO

If you heat your grease to 180F it behaves virtually the same as #2.

And, 20% RUG is way too much. Better is 5% RUG and 5% #2 = 10% & 90% grease.

In the past I've run a couple of 603 and 602 engines on that exact ratio for the 4 or 5 warmest months of the year and never had a problem, probably 1000 a month combined highway and city. It was just easier than fooling around with extra tanks, hoses, switching valves, minimum temperatures, etc., filtered the WVO through a bag filter, de-watered it, blended it with RUG and then pushed that into the tank through a 2 micron water using a Shur-Flo 90 PSI pump. Had a primary filter issue two or three times in the course of five or six years usually right after switching to the blend. When it starts to get colder I just switched over to diesel, never even bothered to change filters.

The 603 has 362K on it and the 602 has 340K on it, both running like sewing machines on original injectors, I'd be doing it it still if WVO hadn't become such a valuable commodity.

I suspect that there is a range of ratio's that will provide decent running but I haven't seen anything other than opinions as to what ratio performs better or worse than any other. Probably depends in part on the quality of the WVO you start with more than anything.

I know people who've blended WVO/diesel and had problems with it, I never had any problem with WVO/RUG blend.

I sit corrected in that my post was just my opinion. I do not know of any magical or scientific formula. I should have preferaced my comment with that. I do know that when you blend with RUG or RUG+#2, the Bar-B-Q odor goes away.

No offense or challenge intended, I just have never seen or heard of any data that offered any proof one way or specific ratio was "better" than any other. I suppose it varies dependent on a number of factors at play, and even on particular engines for that matter.

It seems to me the best course is to start somewhere and adjust a blend if needed depending on how the engine runs. I suppose if someone had some instrumentation they could experiment and at least arrive at some data point relative to the viscosity of diesel and then attempt to approximate that via the blend ratio. Maybe something as simple as a cup with a small drain hole timed for the fuel to run out. Kind of like what is used to compare paint viscosity before spraying.

I've been running a 80% WVO /20% RUG blend year round for about a year and a half now. It has worked fine at 20 degrees F or 80 degrees F.

thanks guys,

collected from bioD/wvo forums:

80% WVO /20% RUG seems to be max allowed due the IP vapor lock.

90% WVO /10% RUG will give me same results as 50% WVO /50% Diesel.

acetone and kerosene will make some room also ...but I dont want to go
that way....

The subject of many a flame war . SVO by Forest Gregg, was an interesting read. Been a while, but IIRC he cited study showing good power and emmisions w/ SVO at 160 F + pre injection. He stated that the viscosity was not the same at this temp, but for various reasons, 160 + F worked well.

www.kiva.org It's not like there's anything wrong with feeling good, is there?

I had my tank out for cleaning a couple of weeks ago. While I was in there I added a 100 Watt pad heater. Just in case a cold snap catches me unprepared I can plug in the block heater and the tank heater and at least have a chance at getting it started!

Bought it from Amazon, Kats silicone heater pad, 100 Watt, 4 inch by 5 inch.

Nope, a source I used to have dumped the grill grease in with the fryer oil. It makes GREAT biodiesel, but the bio will gel at 50F. You have to be really careful about not mixing up your finished product.

Even when running a blend, sometimes you get a cold snap right after some warm weather in the spring. It happened to me this spring. That is why I added the heater. I thought winter was over, added some filtered engine oil, WVO, RUG, and Diesel to the tank. The next week it snowed. Now I have the option of plugging in my fuel tank heater in addition to the normal block heater on the engine. I also added a 60 watt battery heater. The battery is in the trunk on W140s so it indirectly helps to heat the fuel tank also.

Ive been doing 2.5 gal rug, 5 gal diesel or kero , some power service cetane boost antigel and 45 gal wvo. Filter it together good for a couple hours and it works great in my w124. I also add a little fphe and glow multiple times to start when cold. I put new monarchs in and glow plugs before I started too.

Works great so far. Im trying it in my wife's new beetle 2004 pd. I blend 50%petrol and 50% wvo for it until I get a heater on it. Just makes me better.

If I decide to keep my w210 I'll do it in that. I'm curious hw many miles we can get on a 85% wvo blend.

WMO and WVO should not be mixed together as I have been told....?

guys had some trouble mixing the two, something polymerized in the tank and storage and created gel particles.

it is not my experience but other guys reported.

I dont plan to use wmo as a fuel.

cheers
