Oil again

[tahoe healey]

Just read the label on the "high mileage" (green container) Castlol container. I seemed to me the only difference was that it was better for the catalytic system. I found no other apparent other differences. I've always used 20w-50 in the white container. Am I missing something?

Here's a good write-up (disregard the attachment, I went OT for a bit): https://www.autoguide.com/auto-news/2014/05/use-high-mileage-oil-car.html

I'm using Pennzoil High Mileage in my Saturn Vue with 115K. It definitely stops a lot of the oil leaks. Am adding maybe 1.5 qts between 5k changes vs 2.5 or more.
