The manufacture has just changed the color of the bottle after decades of it being orange. It is a little of putting after being so used to the orange bottle. We are unsure at the moment if this has been caused by a shortage of bottles in the supply chain or if it is here to stay. But be assured it is the same product from the manufacture. Same part number and still the best oil to use available. **Q: Mil spec?** A: Yes an exact fit ## Customer Reviews ### ⭐⭐⭐⭐⭐ Have to have it *by S***0 on December 29, 2025* Not much to say, but we have to use this when servicing a seastar system.
