For those who followed and contributed to a recent thread on lubing springs, I'd like to add this.

Weekly Service Letter (Chicago)

Spring Lubrication

"We received a number of front and rear springs which are returned as defective, the statement being made they are weak. Our inspections shows that they have been over lubricated with penetrating oil and that the interleaf friction is lost, with the result that the spring fatigues. We therefore urge the use of Spring Covers for proper spring lubrication, and the discontinuance of excessive spraying with penetrating oil, as springs affected in this way can not be considered defective."

So don't excessively lube and the "loss of interleaf friction resulting in spring fatigue" might explain why the manufacturers of new replacement springs suggest not lubing them today ???
