No way!
It's just some generic oil rebranded for Walmart. They use different suppliers based on region, but all of them are quality oils

ST motor oil?
Since it meets current API specs, no.
While it may not be AMSOIL Signature Series or HPL, it will do no harm.
I didn’t think so but someone on another forum did, figured I would see what others had to say. Thanks
In order to meet SAE grade SP, motor oil must pass tests that ensure their compatibility with various common seals used in engines. ASTM D7216 is one such test.
If you pour it on a Seal, its almost certainly won't be good. Almost no animals can tolerate an oil spill
Ha! Lol
Don't feed seals motor oil, they may die or get hurt for sure. Lol
The person on the other forum is one of the following.
1. Lying
2. Switched from conventional/synthetic blend to a full synthetic which can cause build up to be cleaned up around seals resulting in a already bad seal to start leaking because that build up which was blocking the leak is cleaned up.
3. Just now noticed a prior existing leak.
Supertech is not going to harm seals, no licensed oil is going to harm seals.
My uncles twin brothers step father knew a guy who knew a guy who's cousin that ran Supertech in 2007 make a seal leak in his 1986 Fiero leak .
Told to your friend by someone with a million mile beater..........that leaks.
In your case, a Supreme Possum.
If there is an issue Amazon Basics, Costco Kirkland are in trouble along with Walmart. But no, there are no issues with these quality oils which are identical.
I highly doubt it. I would bet the engines affected had seals that were not in the best shape.
No one is forcing anyone to use super tech oil why the blasphemy?

One should first test for seal clap-ability
Been using Super Tech for years, never had an issue with it degrading seals. It meets the specs for the engines I use it in.
Oil spills have been known to hurt seals.
