Questions about WMO in 7.3 IDI, airplane engine oil... - Diesel Forum

First things first... in my sig you see what I drive... 7.3 IDI 222k miles and she runs beatifully.

I have HUNDREDs and HUNDREDS of gallons of engine oil from airplanes sitting around, and this whole WMO is very new (and interesting) to me. Airplane oil rarely has much water in it, or coolant, and the oil I have has been sitting for a loonngg time... upwards of 6 months.

I am not planning on running 100%, just 50/50 in both tanks... or 100% diesel in front and 50/50 in the rear tank. Is that nessessary, or is 50/50 in both fine? Im from FL, rarely gets too cold here, so is heating entirely needed too??

Here is my issue.... filtering. I am no handyman when it comes to building 55 gallon drum filtering systems. It would have to be bare-bones easy for me to do this. What is going to be the easiest way for me to filter it. I know about the 1 micron filter "sheets" you can buy, but what is the most effective way for a non experienced guy to do this. I dont WANT to go out and buy a bunch of stuff to do it either if thats possible, since I dont know if I would keep this filtering oil deal up for very long!!

Thanks for your time!

Do a search for the threads I have been involved in re: WMO. Search for my name.

I'm doing it now and I drive a sister to what you drive. Within the last month, I've posted quite a bit about my (mis)adventures using oil. I haven't been able to get it to work right all the time but for the overall price, well, you know,,,, it's worth a try.

Just got back from a 300 mile trip Saturday and only burned 10 gallons of diesel. Had some problems along the way and I have been posting my experiences and asking plenty of questions but not many people have had definitive answers. Some post things like "you shouldn't have....". Kinda disappointing but it's all part of the learning curve.

There's a fella around the different boards, not sure if he's on this board or not - JSKI55 - who runs MO and has been doing it for a while, and I plan to find him and ask some questions.

My filtering setup was simple, call it CRUDE. I gravity fed thru a garden hose to a Fram PF8 (Ford engine oil filter) then thru a whole house rope wound water filter. That gave me 10 microns. Or maybe it was 5. I disremember. But I was only able to get about 5 gallons a day thru it but at that point I was patient and hadn't gotten the truck set up to carry the fuel yet. I have since added a 50 gallon tank in the bed and then I filled it with my filtered gold. Since then, I have built a pump from a 4 cylinder Chevy S10 engine to drive the filters. That should increase my throughput.

Anyway, do some reading and post back here to let us me know what you might have found that could help us both.

Whenever I discover something that might help us out, it's gonna be posted here.

I've got a guy who is giving me the oil he collects off of a group of old rotary piston engines from a few planes he cares for.

He said it could be very dirty, but nothing i can't clean out.

He also told me about an aircraft oil that is used somewhere, i'll have to ask the name of it again, but its very corrosive outside of the engines it was designed for. He said it would tear the hell out of my fuel system and all related parts very quickly. I'll get more info in the next few days when i see him again.

I assume your airplane oil is from recips and not jets. If recips should be OK unless you having some exoctic oil if from jets don't use it. Jet oil will eat your seals.

Yes definately search the threads because much has been discussed about using WMO. All good from my end. Naysayers are out there though heheheheh

Airplane oil is probably the best alt fuel to use next to watf.

A. It's thinner, synthetic
B. It is very clean oil.
C. if you have a source it will always keep coming, usually in 5 -25 gallon batches per pickup.

My buddy that gives me his uses k&n oil and he says it has to be changed every 35 running hours. So it barely gets broken down before it gets changed. When I get it you can still see through it, no black at all.
