Is high mileage synthetic oil really worth it?

[tolian21]

Seal conditioners are esters. Therefore, HM oils have higher mounts of esters in their formulations

Then how come many HM oils are being sold at exactly same price? Should this stuff cost more?

I've not had an improvement using it.
Going back to regular syn.
Just as well off using a good syn oil and changing it on time

Here’s a question. Since the esters cause the seals to swell; would switching back to regular synthetic cause the seals to shrink and then leak?

Negative

Only few big stores sell at same price like Walmart and Amazon etc but auto parts stores they expensive then non high mileage.

Hi,
My 2017 Hyundai Elantra Value Edition just turned over to 75,000 miles. The car has been flawless and I still get 36MPG traveling in on the roads in central NJ, NOT even highway driving. I just purchased Pennzoil 5W-20 full synthetic for high mileage cars over 75,000 miles. The price is the same as the standard full synthetic and I was just wondering if the high mileage version can really be beneficial to use, or just stick with the regular full synthetic?
Thanks
Michael in Central NJ

It’s worth it when it’s on clearance like at TSC stores
