Leave the STP on the shelf at Walmart.

With the size of bottle the oil will most likely stay in grade. Don't know if the winter rating will suffer. The add pack will be diluted though, can't escape that.

20% stp would make a 5w30 into the 10w50 light range.
KV100 for STP is approximately 200 cSt where a 5w30 is around 11 cSt KV100.

In most cases it actually dilutes ZDDP. You don't need ZDDP. Newer additives work better and don't make sludge.
Yes it will be dilute zddp since the concentration is below API SN minimum.
Here's the VOA

I think the recommended amount is 10% with STP. One 16oz (400 ml) bottle
for every 4 to 5 bottles of oil. They used to say that it make a 30 wt oil
into a 50 wt.at 10%

Seen a guy at Autozone buying some 10w40 and two bottles of STP. He said he was putting it all into his not very old 4 runner I saw in the parking lot. That brew is definitely thick.

Anyone know what impact Schaeffers #132 has on viscosity? It seems to have a similar viscosity to STP.

If someone can locate the data sheet and get the KV100 we can easily figure it out

Talk about sketchy information. This is about all I could find:
One pint of #132 Moly E.P. Oil Treatment to every 4 to 5 quarts of engine oil.
TYPICAL PROPERTIES
API Gravity 60F (ASTM D-287) 29.2
Specific Gravity .88
Flash Point F/C (ASTM D-92) 475/246
Fire Point F/C (ASTM D-92) 510/265.5

Schaeffer Oil #132 Moly EP Oil Treatment SDS
Right off their product page, the viscosity at 100C is between 250 cSt and 290 cSt.
Using a vis of 270 cSt for the #132 and an 11 cSt starting point:
1 pint added to 4 quarts should result in a 14.36 cSt blend.
1 pint added to 5 quarts should result in a 13.67 cSt blend.

Thanks, the PDS I pasted from showed what I posted above.
