I bought a gallon a few yrs ago, guessing before KungFlu and was a little over $20, now $55. + tax at my dist guess I’m going to be shopping this around since I like to keep clean oil in my 6 cfm JB and 7 cfm Yellow Jacket Bullet vac pumps, few days ago I found the same parts at a different Goodman supplier at around 50% less so pays to shop these F’d up days
