Your statement is only adding to the dis-information/lack of knowledge on the subject. How do you explain my 50k miles using up to 30% WVO in summer and 20% SVO all winter? You are assuming everyone has a common rail type engine, I may risk 20% SVO in a UK summer with common rail but this is still a risk. Saying you cannot use oil without modifications is basically wrong, an old Mercedes in a warm climate will cope with 100% SVO. Indirect injection using Bosch fuel equipment and glow plugs with after start heating makes for an engine which is very tollerant of vegetable oil. Most other vehicles need a thinner fuel though, blending is one way of reducing viscosity, so is chemically thinning (biodiesel), and the other way is by heating (twin tanks or electric heating).
