Anyone know if there is a 2 dollar benifit for 5 quarts of extended HM over regular HM ?
Better base stock ?
Or just a waste of money.
I wiound only be going 7500 on the oil regatdless of which one I go with.
The published specs are so close

Huge difference. It's called marketing.

All depends on how important that $2 difference is. The EP is a stronger oil.
I'll be using strong oils for only 4 and 5k OCIs. But I keep my rides from birth thru old age, junkyard retirement.

Do all EP variants have a pao base stock? I too have wondered what the EP has that the vanilla doesn't.

Stronger? Better film strength or supposed to last longer.

Is $2 really that big of a deal to you?

Nope. Would never miss it, is extended worth any $ extra. Will it reduce wear under normal non extended drains of 7500 miles or is it equal to the regular ?
I see zinc and phosferous is the same.
Does EP have more real synthetic base stock ?

Two ways to look at it: $2 is peanuts, or with a 7500 mile oci, either oil will be fine. Both viewpoints are true...you can’t go wrong with either.

The only advantage I can see with the EP HM is that it has the API Starburst so maybe it's a bit more fuel efficient. Other than that I'll just use the regular stuff. Both are mostly GTL and have higher percentages of AN AFAIK...

Maybe not
The Vanilla Mobil-1 may be shot at 7.5k. The EP may have a few thousand left in life.

There is a reason why EP sells for more money. It's a better, all-around oil. To me, I'm saving $2.... not spending extra $2 for it.
Yesterday's original Mobil-1 Vanilla is today's Mobil-1 EP.

I read somewhere the 5W-20 EP HM had a very high PAO content. Something like 80% that may mean it's VII Free and actually an SAE 20. Might work really well in engines that tend to be hard on oil.
