It takes about 0.5l of diesel fuel to regenerate a dpf. 0.5l every 300 miles or more isn't anything that would concern me, and certainly not if the HVO100 is more expensive than regular diesel fuel. Even if you can halve the DPF regens there's no savings from fuel in it over the lifetime of a vehicle.It's not supposed to be like the regular biodiesel. Hydrogenated vegetable oil, and at 100% they call it synthetic diesel with no amount of regular diesel. It is renewable, and here in Sweden made of leftovers from ethanol and butchers leavings. I know Mercedes has tested it in their new 2,0 CDI engine in the taxi cars, and Volvo and PSA is using it. It should reduce the soot alot, so the DPF is working less, with less need to regenerate, and that alone will net consumption. Some rumors that it has a slightly better cetane number, but that I hoped someone knew more about. It is said to reduce the emissions by 80-90% over the regular B7 that is sold here. And the HVO should have a summer and winter version. Anyone has more insight in this? And tested it? What happens to the motor oil with this? I was thinking of trying it in my older V6 CDI engine.Originally Posted by Randwould that be similar to b100? upto 5% biodiesel is common, 20% less common, 100% nearly unheard of for various reasons. but it varies widely by region.
