Hi Guys
My wife owns a resturant. I thought I would take advantage of her and steal her used oil to use in my powerstroke. The only problem is she only go's through 8 to 10 gal. a week. I normally use 25-30 gals of fuel myself per week. Can diesel fuel be mixed with the bio at a 50/50 mix? Has anyone dont this? I would need to find 3 other resturants willing to give me there oil to make this work.

Thanks for your Time
