Pennzoil Ultra Platinum 5w30

[DerFahrer]

Has anyone noticed the new jugs are not labeled "Made from Natural gas" whereas the older ones were?
Perhaps due to the Pearl GTL plant offline? Shell saving limited GTL base for Euro oils? Just opening up for discussion.

Yes it’s been noticed, back in March:

Thread 'Pennzoil Ultra Platinum no longer GTL base?'

When did SOPUS stop marketing, or halt using, GTL base oil in Ultra Platinum? I guess with Pearl GTL Qatar getting hit, this may have been a proactive change.

From Walmart yesterday (but was on sale cheap)

Hmm, I'm wondering why they changed cap color.

Because the oil went to the dark side.

Joking aside, I thought the color was grade specific? Those two in the pix are same grade.

I also noticed that Mobil 1 massively upped all their their pour points listed on the PDS'. For instance, Advance Clean 5W-30 now shows a very pedestrian -33C PP that was previously around -45C. But I could also be completely insane...

Ok, I googled "Pennzoil bottle cap color meaning" and it seems silver cap indicated top quality synth oil while black cap is for conventional?!

So the old bait and switch deal.

This has been discussed a bunch. It's still GTL. It's just a marketing change. Pennzoil didn't think people understood the significance of it, so they just removed it from the label.

There's also the disclaimers about variance in different production batches, different manufacturing locations, and subject to change without notice in Mobil's PDS documents.

Was that an AI response?
