I know we just got done with a blending thread but I wanted to ask one more question.
If I get only 5 gallons of waste oil per week can I just filter that and add it to my tank along with 16 gallons of diesel?
Also, do I need to hand blend it or is just adding it to my tank and letting the movement of the car do the blending enough?
About May 15 is the time in Denver when the temp stays above 40 even at night so I'd probably start trying this about 2 weeks from now.
Thanks to all,
