i hate to answer my own question but ,i did a little research. some people heat it above 160 f and use it straight ,others mix it in various combinations with diesel fuel. i even found epa regulations on how much wholesalers can legally mix with low sulfur diesel fuel . we probably have had some in our tanks from time to time without knowing it. it does not have the glycerin that veggy oils have so you don't need methyl or lie to process it. it seems to be a filtering and viscosity issue.this deserves more research!

some pour it from the oil pan into the tank.... Ive heard others who strain it first and then into the tank... thats my plan, strain down to 10u and into the tank.

i filtered some today and mixed it 25% with 75% diesel i drove 80 miles with it in my 96 f350 7.3. it ran great no difference in smoke a little better mileage.i went ahead and upped the concentration to 50-50 it runs great.i left straight diesel in my rear tank,5 minutes before i shut down i switch tanks so theres straight diesel in the filter bowl when i start up cold. so far so good

I'm curious, do you think it'll work with common rail???? If I get too much 2stroke in the mix she seems a little slower, I can't imagine straight used oil no matter the blend.

i am no expert but i just read that new 2 stroke oil has additives and that used oil has broken down the additives making it better for the injectors. i haven't tried it in my kubota 7040 yet i have to wait till the warranty is up in august. i am going to try it in my 466 int and my 1984 6.9 diesel. also my truck is programmed edge evolution extreme setting i don't know if that makes any difference or not. i'm a novice whats common rail?

You got to remember that WEO doesn't have the lubricity of new engine oil or 2 cycle oil. So you might have to add a bit of fresh oil to it to keep the HFRR value low...

Basicaly there both the same for HFRR. But I'm pretty sure the Standyne cost more... But not by much...
