Just cause it feels great...
Ran my 2nd day with my 85 300D-T today on blend of 1 part RUG to 4parts WVO and no modifications single tank;
runnin' great;
I did have to change fuel filters this AM; the primary ; don't know how long it was on prior to me owning it; was clogged and black on the inside;
(thanks; Matt300sd)
I Love the smell of Tempura in the morning!!!!
So far did about 55miles and no difference in the way she runs; other than the sweet smell of WVO and running my AC without having to care about my MPG!!!!

Any 300D owners interested in this It is easy!

Sorry for the ignorance but what is RUG?
thanks
Joel

Hi Joel!
RUG = Regular Unleaded Gas

FWIW all, I notice a distinct reduction in idle speed and off-idle performance when running straight WVO, not to mention a significant reduction in mileage.

Right on- I've been running WVO / Diesel blend for 3 months now- definate improvement in having more power and less noise. I had to change fuel filter once, but like yours, it was probably ready anyway- I don't believe it was the WVO that blocked the filter, as I pre-filter everything out to the point that my WVO is clear. I do see variations in color of my final WVO however- depending on what was fried in it I believe. The color variation does not seem to alter performance or behaviour. However, during a real recent hot spell, I thought I'd try some WVO in the tank which I could not get to come clear- too much tallow in it, although in the heat it seems to flow OK. The car runs on it, but the idle is rougher and there is a definate loss of power. This stuff has to be HOT, not just warm to run in the car effectively.

I've mentioned on a couple of threads that my car knocks quite badly when running on straight Diesel-- this started long before I started blending in the WVO. When I add WVO, the knock goes away, so it's like the WVO is acting as a good fuel conditioner, against whatever is causing this knock. I'm asuming I need new injectors- gonna get this verified this Friday. Meanwhile, the WVO is keeping the car drivable for me.

Unfortunately, I've lost my WVO supplier. The restaurant owner has decided to keep it for himself, since finding out it will also work for home heating. All other restaurants in my small town are giving their WVO away to a hog farmer to mix in with the feed. I've asked at every one of them- same story. What a waste!! One owner seemed interested when I told him I'm recycling it as an environmentally friendly fuel, and said he'd think it over and give me a call. Meanwhile, I have about 30 gallons of WVO left. When that is gone, I'm not sure what I'm going to do for a supply if he doesn't come through. There are several other small towns and one city within a 50 mile radius of me, so I guess I need to expand my hunt.

Good luck!

Welcome to the fold. I am also running a single tank system, though I inistalled a coolant-operated fuel heat exchanger.

I run 100% wvo right now - I will mix as weather cools.

So far I have 9000 miles in wvo. I drive 3000 miles a month and it saves me over $200 a month after expenses.

I also found a new supplier. There is a small place that makes frozen chinese food next to where I work. They have a 3/4 full dumpster that has been sitting for weeks with no new oil and it's settled and clean. This winter they said they will put it in cubies for me.

My idle speed seems OK . It's at 8K rpm... I don't care about the MPG because it doesn't matter anymore on WVO! That's the great thing... it's irrelavent .
NO War necessary!
And the filter clogs because WVO disolves stuff in the tank that diesel didn't after 20 years...

[QUOTE=tenknots]Welcome to the fold. I am also running a single tank system, though I inistalled a coolant-operated fuel heat exchanger.

Hey tenknots, so do I. I just installed a greasel kit in my 82 300D. Works just fine...runs on 100% wvo. However I've not been able to get the coolant to circulate into the new heat exchange system. This is my last problem with the installation of the system...no rush I guess. It’s going to be in the nineties all week here. Can you or anyone help me with this?

By the way at what temp will it become important to start heating up the wvo...I'll be in Canada next week and it goes down in the fifties at night already where I'm going?

Make French fries not war!

I pulled the other 4 injectors and cleaned them over the weekend. They all looked like the pictures - plenty of hard carbon build up. I soaked them overnight in acetone and the stuff just wiped off.

Also, I pulled the #1 injector, the one I cleaned a few hundred miles or so ago and it was already starting to form a thin black crusty film around the tip. I can only suspect the oil I'm getting has something in it causing the coking.

In the interim, since I have a hundred gallons of that filtered oil, I have begun to blend 10% RUG. One immediatly noticeable difference is in starting. Before, the engine ran a bit rough for a minute or two when started cold (70 degrees overnight), it now idles the same as it did when starting on diesel.

I'm hoping the addition of RUG may slow the coking until I can get another supplier. I'll pull the injectors again in a month (3000 miles) and check and report back.

Thebignight: First make sure your plumbing is right. Do a search here and you'll fine pictures on where to T the lines. If you've got that right, you may have a bubble in the system. Try running the heater - if you get no heat, you have an airlock somewhere. If you get heat, your plumbing is wrong - you should get flow through the exchanger.

I believe you should always heat WVO, especially straight WVO. 150-180F is probably OK. I'm heating my blend to about 150 or more. Since this is my first hot day on blend, we'll see how it works in the 95 degree ruch hour traffic crawl. I'm fairly certain that at higher blends (20% this winter) less heat is needed, but colder outside temps may offset that. My heat exchanger has a valve in front of it and I can very the amount of heat or close it completely.

Take the injectors apart and clean them out when you take them out of the engine. Carbon build-up on the bottom of the injector is normal and is not an indication of a problem.

Now comes a stupid question, what is WVO?

How are we doing so far folks ? :-)

Wow...almost 5 months on Blending.....

I have been running for past 3 weeks on anywhere from 15 to 50% Diesel blended with WVO (50-85%), with the PS; acetone and un-named diesel additive. And aside from runnig out of fuel a couple of times because of a bad sender unit....my car is running better than it has since I started blending.
I hope I don't see wax but I would think that would have shown up by now.??
Maybe the PS is helping prevent this ???It is an anti -gel....
