This might be dumb or weird to ask but is high mileage oil safe to use? I read someone on Reddit say that it could potentially damage your engine since the extra detergent and other high mileage additives are potentially adding more weight to the oil thus putting more weight on strain/stress on your engine ? Is this true? With that being said if it’s not, is high mileage oil even worth it?
High mileage oils won't damage anything but they don't have any real benefit either. (The seal conditioners included might help lube up old seals, but even that is questionable.)
There is a lot of hearsay, marketing and propaganda on the internet. Most of it BS.
The only source of data I could find was this page:

The guy claims to have some high-falutin credentials, but ironically he won't put his own name on it. Just goes by "540 RAT". Season with salt as required.

Reddit's not exactly the kind of thing I'd trust at face value. Scotty uses that logo as his picture in picture sometimes when he's talking about people who don't know what they're talking about.
I once accidentally put 5W-20 high mileage Pennzoil Platinum in my 2017 Mustang when I did its first oil change at 3,000 miles. It didn't do any damage to the motor. I use high mileage oil in my 1999 Ranger with 272k miles and also my 1979 Catalina as well. No issues.
To answer your question - Do I smell livestock in here?
