You recommend 'ordinary machine oil' for 3cfm pump. Any oil? For this pump can it be synthethic Mobil1 0w40 or rather compressor oil or maybe half-synthethic Milers 5w30?

Answer This Question

The requirements for the vacuum pump are not high. You can use Mobil 1 0w40 oil, compressor oil, or semi-synthetic Milers 5w30 oil. There is no problem with these. It is best to use vacuum pump lubricant.
