I've run both,for performance I love waft.WMO is embrassing to drive around.Smell like you never a overhaul.You can blend 10% and not stink up the world.I also don't use used diesel oils because of black carbon.This carbon will act like lapping compound in your IP.I've used gasser oil up to 50%.
WATF though is rocket fuel for a diesel just filter and use.WMO is better for waste oil heaters,and Tugboats.

 

I think it is depends on the quality of the oil and oils ability to keep engine clean, i think 3 microns could be better enough to keep engine clean and run smoothly.

from what I have been reading here and on other posts there seems to be a consensus that .5 microns is the standard because of the tolerances in the injectors and the ip I am personally going to filter at .5 twice before I blend and if you use a dual tank with a heated system you can run up 90% if it is heated to 180 degrees if any one is doing this I would be intrigued on how you do your settling system and filtering and when I get mine set up I will do the same I also found this on ebay for the water

Do you use pressurized filter, or just let it drain through?

 

to all,

fwiw, i have a 1991 F-250, 7.3L IDI, with NO turbocharger.

is anyone here running such a IH-engined rig on STRAIGHT/filtered WMO
&
if so how many THOUSAND miles have you done so?

My 15 micron is a gravity flow,next 5 micron,then final stock 10 micron..5 would be good for a bag filter,but one on vehicle would starve the IP.

 

I can't use motor oil on my 2008 6.4 POWERSTROKE DIESEL for fuel, I think modern diesel engine with DPF will have problems

 

Thanks OS111. My son works at a parts store, so I can get a little extra sometimes. Just wanna know how to filter it.

 

I ussally run gasser oils,as the keep my fuel where I can see through it.
I,m going to experiment on used diesel oil and see if I can water wash it.

 

oldsinner111,

please let us/me know how that works out & how you did it. - at the current price of "pump diesel", i'm thinking seriously about using WMO, suitably filtered, for fuel for my 1991 Ford F-250 IDI.
