Can any diesel engine use B5?

Yes. B5 can be used in any diesel engine without modification. In fact, biodiesel improves the lubricity of diesel fuel (especially ultra low sulfur diesel) which enhances engine performance and can prolong engine life. All engine manufacturers accept B5 as a standard fuel.
