I sent a sample to Carter Cat labs for VOA. I feel like these results are not true. Isn't a V100 of 13.8 a 40w?

SAE 30 is SAE 40 is Per SAE J300.

Maybe the results are true and your oil is heavier than you thought.
Maybe the results are false and the lab bungled the analysis.

Who knows?!?!?

I know something is wrong. I poured it myself from a sealed motorcraft quart.

The fact that you poured it yourself from a sealed Motorcraft quart is both true and irrelevant.
The original question that you posted was around the VOA viscosity analysis results.
Right now you have no idea if the oil is thicker than expected or if the analysis was goofed.

I go with the later.
 
I'd call them and make them re run it...I'm surprised that 100c value wasn't flagged because that's clearly an SAE40 value (-and also, i don't believe SAE40 can be RC, which this MC oil is labeled as such).

Curious, do you have a 40c value to compare it to PQIA?
