Reply to "Contaminant identification."

Dear Ariel,

Other way to determine the problem could be:

Run a spechtometric analysis to your new ISO VG 220, new ISO VG 46 and your current oil with viscosity of 150 Cts. Then, you can compare the presence of additives in the samples (Ca, P, Zn, etc), and to determine, if you have had any contamination.

The oil could be contaminated (with gasses, fuels, deppending of the application), and viscosity has decreased. For this, you should run a typical tests package (TAN, Flash Point, Particle Count, Water, Metals, etc)

It would be very important to know a little more about the application, and the industry where this problem has happened.

Best Regards
