You will have to open it up to add the oil any way.
They are the exact same DL with a different label on the front of the can. When my Cantenna finally developed a slow leak because I had it placed under my house I went down to Home Depot and bought a new empty 1 gallon paint can. Popped top with the load on the new can filled with mineral oil (Walmart brand baby powder scented of course). So for $5 I have like new Cantenna. These things just about last forever.
