Silicone sprayed in the intake can poison O2 sensor
With all the spraying on ISV's etc going on, just thought I would mention silicone oil even in tiny amounts can poison the o2 sensor, which stops working and needs replacing.

The WD40 website won't say what is in their product, but they do say what is not in it. They claim it contains no silicone. See link:
