Better bring a few extra gallon size jugs of oil to the strip.
Better bring a few extra gallon size jugs of oil to the strip.as fer how much oil mist the compressor needs it doesnt require much but PAG oil is thicker for high heat...besides being a much better lubricant...but the beuty of this lowbuck Compressor vacum pump, is that it'* on a clutch
...so a 1/2 qt of oil every few minutes would translate into about 8+ 1/4 runs before you needed to drain the oil catch tank/breathedr can.... and even then a properly designed system, this wouldnt be required (see my thread involving Ron V)Oh BTW my idea is to actually use the variable displacment compressor to an advantage since at high rpm the displacment can be lowered to reduce drag, but still maintain max crankcase vacum...
