WebStep 2: The PFPE grease was tested for oil separation at 400'F for 200 hours and gave a better result than Li-Complex grease which was tested at 400'F for only 24 hours. Step 3: The remaining PFPE grease from Step 2 gave almost the same result when tested for torque at -100°F, but the Li-Complex grease becomes frozen at -100°F. WebMixing of grease can be determined by looking at thickener type and additives. Contamination is given a red rating. The FTIR shows mixing of two incompatible thickeners in the sample. Mixing of polyurea and lithium complex grease caused the oil to run out of the grease leaving only the thickeners to do the lubricating.
