can i filter waste oil good enough to mix with deisel fuel to safely run my case 1845 skidsteer
simple answer is yes, but you need a heater and a 1 to 2 micro filter. I looked into this and found it to be too expensive.
Best thing I have found is to heat my shop with it then the money I save can be used to buy new oil and fuel ware needed. There is more BTU in waste oil then #2 heating fuel. so 55 gal of waste oil lasts about 1/4 longer then #2 in my place.
