  1. My Cat Pump calls for an ISO 68 hydraulic oil, is the Mag 1 safe to use in Cat Pumps?

    1. SAE 30W oil is rated at ISO 100. ISO 68 is equivalent to SAE 20W oil like the Cat pressure washer oil item 22158 shown below.

      Helpful?

    2. order pt # 22158 special for Cat pumps. Mag 1 is not good for a Cat pump

      Helpful?

  2. safe for general pumps? 4000psi 4gpm

    1. This pressure washer pump oil is safe for any pump that can be used with a 30 weight, non-detergent oil, which will cover the vast majority of pumps out there.

      Helpful?

    2. This Pressure Washer pump oil is safe for all pressure washer pumps.

      Helpful?

  3. Correct oil for Compressor's?

    My Honda air compressor manual states to use this oil (#4043) for the compressor pump oil. However the description here states it is for presser washer pumps. Can this be used for Air Compressors. My model is 459222.

    Thanks

    1. This is universal oil that can be used in an air compressor or a pressure washer pump.
