Yup, that was the reason why.

I knew some members would have fun at my expense. No problem though, i'm self-deprecating too.

Does anyone know what base oil do they use? Is it GTL or PAO?

Not sure because it is higher in Zinc makes it quieter or not.
This oil is quite high in Zinc, 1000+ ppm. If you are concerned with the Zinc, may be bad for the catalytic converters.

The amount of zinc in a oil won't make it quieter.

^correct. It can't be more than that or it wouldn't meet SN/GF-5.

Basing it off from the old specs from PQIA.

Those wouldn't be Rotella Gas Truck but Rotella diesel and mixed fleet oils.
