I’ve considered using air tool oil on my air-operated windshield wipers, which have been hesitant and intermittent. During a recent trip to OysterFest with heavy rain, the wipers got a good workout and seemed to improve, but they could still perform better. I’ve switched to a small 12V pump for the washer system instead of the outdated air-operated washers, and now I get plenty of water and solution on the windshield.
