Oil change places and shady mechanics are all over in the industry. Oil change places especially LOVE to scare and upsell people on services they do not need. All one has to do is look in their manual to find out they’re being peddled services that are often unnecessary. The NTSB and various manufacturers even issued warnings that these services often damage your vehicle.
Honestly, this info is all over in the manual, but it was great to find this info in one place.
