My car only has a ten gallon tank. Would it be safe to add the whole bottle?

You can use the whole bottle, or make it go farther buy using half a bottle and two full tanks of gas

Does it work in diesels?

I would contact the company & ask them. Here is the link to their contact information: https://lucasoil.com/contact
