Gas, Diesel, WMO

[k_williams1982]

As I was telling everyone, when I got my '85 it has gas mixed in with the diesel. I pumped about 22 gallons out of it and put fresh diesel in the tanks before I started the engine. Judging by the smell of the old stuff, I thought that it was mostly gas. My brother decided he wanted to run it in his three-wheeler (it's a two stroke, so the diesel shouldn't of hurt it). The problem is that there is more diesel in it than originally thought because the fuel fouled his plug and gummed up his carb. I have about 10 gallons of WMO and used ATF in gallon jugs in my garage. How much should I add to the gas/diesel mixture so that it won't foul up my engine? What's the cheapest way to filter the WMO before I mix it with the fuel? Can I use an electric fuel pump to pump the WMO through an inline fuel filter and then into a clean container? I have about 20 gallons of this gas/diesel mixture left in my garage and have no way to dispose of it, so I'd rather use it and get rid of some of this WMO in the garage at the same time. It's starting to get a little cold around here at night and in the mornings, so I don't want to mix it too much and have the truck not want to start for me in the mornings.

mix the old stuff about 10% and you should be ok---you could also add some of the atf--gallon to 15 gal-----gas is "dry"--hence the atf provides the lube factor for the ip---

So I should be fine if I mix 1 gallon of WMO with 9 gallons of the gas/diesel mix and then add 1 gallon of ATF to every 15 gallons of the "new" mixture? I just want to make sure that I understood correctly. Thank you for the advice.

Anyone know if my idea on filtering the WMO will mork?

no reason an inline filter and pump wont work just check the micron rating on it, you want to be around 10 microns at the minimum. honestly you can get away with more than 10%, they say you can run 10% gas to strait diesel, so being that you have atf and wmo i would blend the wmo and atf 50/50 and then run 50% W O and 50% diesel/gas.

If you think its pretty heavy on the gas to diesel mix I would use atleast 1/2 WMO or tranny fluid or both. If your worried about starting in the cold use one tank with straight #2 and use the other for the blend. Start on #2 and switch back a few miles before shutting off so the filter and IP is full of #2.

The last week or two I have had access to lots of WMO but no money for a good filter set up with any sort of micron rating....Just get two 5 gallon pails, cut a hole in the bottom of one attach some cloth, jeans, sheets etc, double layered and pour the oil through.

I'm going to start by pouring through a coffee filter into a clean 5 gallon jug. Then I'm going to pump it from that jug through two inline filters and into another jug. I'll take the filtered WMO and mix 2 gallons of it with 3 gallons of the gas/diesel mixture and see how it does. I talked to Towcat this morning on the phone and he told me to check out his link in the Biodiesel section. I don't have the money to buy the setup right now (I intend to soon), so I just put some straight #2 in both tanks this morning (I now have about 1/4 tank in the rear which is the tank I'm going to put the WMO mix into). I was told that this ULSF diesel is ******* our older engines, so I've been adding Diesel Kleen to my fuel already. Is it better to run "offroad" (dyed) fuel in these or not? The other morning the gas attendant put the dyed fuel in the truck and it seemed to run better and have more power. I'm heading out to see how messy I can get myself and the garage floor.

BE VERY CAREFULL RUNNING DYED FUEL i'm not sure how it is up in oregon but down here if you get cought running it they will practically hang you. aside from that it does run better, IIRC off highway is 500PPM and the new highway fuel is 15PPM. it is not actually the sulfur that is the lube in the fuel but certain particles that tend to cling to sulfur, so when the take it out of the fuel all these little particles go away with the sulfur. the fuel companies claim they put addiquate lubricity addatives in this ULSD but i dont buy it.

I have had a similar event. Seems my 78 (soon to be 79) year old father and 74 (soon to be 75) year old mother decided to top off their boat on the way home from the lake recently resulting in about 35 gal of diesel mixed with 35 gal of gas. We didn't want to risk using it in any other application so I used it to help rid myself of some building material and old wood that had been cut off my property. This pile (very large) was in a drainage area (low area) and was the last thing I needed to do to have cleaned the entire piece of ground. One should note that the fumes remained in the low lying area and created a somewhat less than appealing explosion for the homes closest to mine (removing some pictures from walls) and resulted in the local law enforcement being called. Needless to say, I'll not be lighting off any larger quantities of fuel in the near future.

Oregon isn't too strict on the dyed fuel. Accually Bend doesn't even enforce DEQ. A person can be fined for running it here, but nobody checks the pickups running around. A friend of mine would fill one tank with #2 diesel and the other with dyed fuel. He'd run the dyed fuel out in the woods getting firewood and switch tanks on the way back to town.

I filtered out 3.5 gallons of WMO and mixed it with 3.5 gallons of the gas/diesel mixture and dumped it into the rear tank with about 5 gallons of #2 diesel. I took off on diesel to get it up to operating temp and then switched over to the "cocktail" that I had mixed. It ran fine with no noticable difference in power. After about 20 miles, it started to "rattle" a little bit and seemed louder than normal, but stayed running. I called Towcat worried I'd just messed something up and he said that's most likely the gas in the mix "pre-igniting", so I'm going to add 2 more gallons of straight WMO to dilute the gas a little more. I'll keep everyone updated as I continue to play with the mixture.

P.S.
I don't recommend using an electric fuel pump to pump oil through... I burned up two today, and one was designed for diesel applications. I filtered the oil through a coffee filter first, and then gravity flowed it through an inline fuel filter into my mixing container.

Not that I have any useful info to add, but this was an insightful read thru.......just figured I'd add that.

If you do a search online there's a farmer in the mid-west who makes fuel from pressing sunflower seeds he grows and cuts it with RUG (reg. unleaded gas). He runs it in all his tractors & trucks. He gets a lot better fuel efficiently . I forget how I found his site, but he gets great results & has been doing it for awhile.
I knew I should have bookmarked the page.

Here's the final mixture results...

I made one hell of a "cocktail" and I'm pretty impressed with the results.
5.75 gallons of the gas/diesel mixture
8.75 gallons of WMO (7.5 gallons of 10W30 and 15W40 - 1.25 used ATF)
4.00 gallons of #2 diesel

I ran the truck 68 miles on the final mixture and pulled into the fuel station (I topped it off with #2 diesel just to have an accurate measurement of usage). It took 3.5 gallons to top it back off. I averaged 19.4 mpg on my "cocktail". Taking into account the amounts of the mixture that I'm running, that means the whole trip only cost me between $1.40-$1.60 (my out of pocket cost). The truck ran great with what felt like more power and didn't run any louder (no more pre-ignition).

I think that's pretty good mileage considering that I have a C6 automatic and 4.11 gears. I ran the turck at between 55-60mph for most of that mileage.

Isn't 1 gallon of gas equivelent to 1 stick of dynamite or something like that, when properly vaporized? Yet, I bet you did get some attention.

That's what I was always told. Then again, I've also been told that the vapor is more flammable than the liquid.

The fact that you lit 70 gallons of fuel on your own property makes you my personal hero!
