what is going to happen when this new ultra low sulphur diesel comes out? Am i going to have to put something in every tank every time i fill up?

 

You should already be putting an additive in there to help lube the fuel system,every tank.

 

Yap, get used to using a good additive.

You should already be using something to provide lubrication to the IP and injectors.

Check with your fuel supplier to see what they are doing to improve the lubricity of their USLD, chances are if they don't know they don't add anything.
