I know this can of worms has been opened several times on here, i did a search. What is the best oil to use for these compressors? I have read to use rc car shock oil, treadmill belt lube, yada yada yada. Could I just use pb blaster silicone spray put the nozzle in the oiler hole and give it a short squirt? Crossman airgun oil? Air Venturi compressor oil? As always any and all help is appreciated. Cheers
