WVO/Diesel Blend

I would like to try a wvo/diesel blend in my 83 300d. Does anyone have any experience with different ratios.

start very light on the wvo, maybe 1 gal. per tank. Change your filters often(every tankful) and slowly increase wvo to about 70% this summer. The wvo will clean all the crap from your fuel system so clogged filters will be a problem at first. Filter your oil to at least 5 microns and allow ample time for it to settle.

WVO will CLEAN the system? of this I was unaware. I know BioDiesel will clean due to the de-esterfication of the base oil, but WVO? I gotta see proof of that! I certainly agree on the filter maintenance, though!
also, of the ones mixing WVO I thought they were mixing with Gasoline to thin the Oil down to Diesel viscosity. thinning WVO with Diesel would thicken the diesel...

Although I cannot vouch for the cleaning property of a WVO blend, and I have not read any information that indicates it has cleaning properties, when I got my 126 back in July it had a goofy fuel sender that I had resolved myself to having to remove and clean, but after a few tanks of my WVO blend the problem resolved on its own.

I'm not aware of any 'cleansing' properties of WVO either. You do need to settle and filter the WVO, and it would not hurt to dewater either.

I highly recommend that you find and use an inline heater for the fuel. WVO is much thicker than #2 and needs to be heated to inject properly. You will also need to carry spare fuel filters.

I'm going to install a heated fuel filter within the next few months. (I already have one from Davco.

I would recommend carrying extra filters, tools needed to change them, and a qt of atf or sea foam, to fill the spin on should you need to change it.

replacing filters every tank ful is throwing money away. I blend, and have about 4500m on my spin-on, and have changed the inline twice in that time. the only reason I've had to do that is I did not dewater godd enough, and developed fungus in the tank. or maybe that was from dumpster diving. regardless, I use biocide now, in everytank.

I have run 10k+ last summer on 100% wvo, and blend in the winter. one tank. I use a home-made gloplug heater, and injection line heaters.I recently built a filter heater for the stock filter. I do have a few Injector line heaters available, to members, for $25 shipped.PM's work. I may be offering the filter wrap soon.

I started light- about 50-50. last spring. I now blend according to weather. i only fill up when i need to use the car, adding aprox. what i need. this is not really inconveinant, as I fuel up in the garage. I always leave room so i can go top up on diesel, if the weather turns bad. so far, so good.

I had my car start at -25F, with about 10-15% wvo, no block heater.

you will be surprised by how smooth and quiet your benz is on grease.

this is a gamble that everyone must make for themselves. it is risky. my engine my self destruct tommorow. or it may go another 285K, no problem.
I doubt either one. somewhere in the middle is what will probably happen.

good luck,mo

I ran 100% BD for my first 8k miles or so (from Sept 06 through Dec 06) until it got too cold to brew BD in my unheated garage.

Since then I'm running 80% WVO and 20% RUG (regular unleaded gasoline). About 2k miles.

Fuel filter changes early on, as is common knowledge with BD.

Then about 2 weeks ago I mistakenly put my filtered WVO/RUG blend into a container that had some sediment in the bottom and poured this into my car tank. I changed my primary filter about 6 times and secondary about 3 during the course of that tank (most of them roadside). All is better now. Lesson learned...filter the hell out of your WVO and use clean containers!

No starting or driveability issues with the WVO/RUG blend, even down to single digit temps outside.

I do limit my use to Canola WVO. I leave all my jugs of collected WVO in my unheated garage for a few days, and then only choose the ones that are still liquid when I need to make a batch. The rest wait for warm weather to get transesterified into BD.

I've got about 20k on a blend. I started blending WVO with regular unleaded, up to 20%, which worked great until I added heat (a 26-plate flat plate heat exchanger and injector line heaters), which vaporised the gas and gave me trouble. I still add a bit of gas. My current (winter) blend is a half gallon of gas, 5.5 gallons of diesel, and 14-19 gallons of WVO (20-25 gallons total, depending on ambient temps). It's running great.

In my opinion, the cleaning properties are the fact that WVO suffocates any algae in your tank. You'd be surprised how much there is in there. Lots of primary filters and secondary filters are a must, unless you clean your system with a fungicide. Star Brite makes a good product for this. I didn't use it, and it took about 5,000 miles to get to a point that I'm not replacing filters weekly.

If your fuel system isn't heated, I'd suggest (based on a number of success stories) blending WVO with regular unleaded gasoline (RUG). Start at a 20% blend. For more information, visit biodiesel.infopop.cc

Update on my WVO/Diesel blends

I've been filtering my WVO through a pillowcase and into a 55 gallon drum. In the summer I mix 50/50 WVO/diesel with no problems. I have put about 3000 miles on and haven't changed my fuel filters yet.

Talking WVO general info, please...

Hi y'all

I haven't searched the forum, and am a newbi to it in any case. I happened across this thread... and not wanting to hijack it, y'all can email me direct at vileine18sq at hotmail.com

If y'all would, I'd certainly appreciate any direction to general info about WVO.

So far my information indication is that WVO needs blending/heating and addition of methoxide to knock off glycerin?

What's y'all's processing tips?

My situation: I live in coastal Miz'sippi (min temps in high 20s). Car is an 87 300 TDT. It has been run on B100 before and is running fine.

Thanks in advance,
tami

WVO will not clean out your tank. Live in NE PA-I start in April burning home made bio.Then in May burn 5 gal of WVO and 1 quart of gas. Change your clear filter every 3000 miles and spin on filter every 5000 miles. Have about 16000 miles on WVO. If you feel a power loss change the clear filter.

Interesting english. You type like you talk?

This page has its critics but there is good info there.

this is about the best, non biased fourm for running on grease OR making bio=http://biodiesel.infopop.cc/groupee/forums

do not use methoxide if you are running a blend/ straight veggie in your tank. you will make bio in there, and end up with a mess.

this thread is regarding running wvo with diesel, or gasoline, without doing a two tank convertion.

this is not something you would want to do if you are not familiar with your car. this is not recommended by many, many people. this is risking seriuos engine damage.

that said, I've been doing it for about 15K, long enough to pay for a used engine for my ol' beater.
