QS Full Synthetic vs. QS Ultimate differences?

[GaryMX5]

Are there significant differences between QS Full Synthetic and QS Ultimate protection oils?

I have been a dedicated user of QS full synthetic oil for years now (and QS Ultimate Durability before the name change) in all my Mazdas (8 to date). The full synthetic is getting harder to find either due to popularity ( lower cost) or maybe declining sales at my local Walmarts. I liked the increased levels of moly (which Mazda seems to continue to incorporate in their oils) in the QS full synthetic. Does anyone know if the QS Ultimate Protection has increased moly levels or comparable moly levels to QS full syn? Ultimate Protection is more readily available and might be my future option. Thanks

In a couple VOA samples on each of them contain around 140PPM Moly. Not much different in that regard. The UP is a 20K oil so kind of for extended drain intervals. I use it, but always drain at 5K. The Ultimate protection may have a better base oil (GTL I think, similar to Pennzoil.)

Somewhere I saw where QS said QS Ultimate Durability uses a GTL base oil I think it was on QS website.

QS, Pennzoil, Shell are under the same parent company

Probably to stop infighting among the Shell brands...

Don't think Menard's reaches out as far as Colorado----but for people w/a Menard's near them; Menards stocks QS Full Syn at very competitive prices
