The weirdest thing happened to my 2001 Nissan Altima. I was changing the oil and afterward, I put in oil treatment into the engine - and when I started to drive, the power steering started to make the steering wheel harder to turn. Any ideas?
EDIT: It's probably not the oil treatment that made the power steering worse. There might be other factors. I'll look into it when I have more time.
EDIT 2: It might be the power steering belt. Going to check when I can.
This was linked, which I find interesting: How much power (HP) do the components on the engine belt generally use?
