Long time Amsoil user since 2004 90% of the time. Amsoil is 14 and some change with preferred pricing. Since HPL is 2.00 more is it worth switching?
Amsoil vs HPL; cost difference worth it?

No, I would and will stick with Amsoil. Plus I normally buy in gallon cases which is less than that a quart.
The API Royal Purple at Walmart is a "step up" from Amsoil?
Royal Purple would definitely be my choice if I chose boutique oil.
Royal Purple is not exactly on the level of Amsoil and HPL.
I use High Performance Lubricants, I have also used Amsoil. Either are top shelf choices. Can't go wrong with either brand.
Were it me I would go with HPL based on their willingness to interact with folks from this forum and general transparency (plus I disagree with Amsoil's marketing/sales strategy).
That said, I barely put 5k miles a year on my car so it's Valvoline Restore and Protect or nothing for me.

I’ve read before here that AMSOIL Signature Series would fall between HPL premium plus and premium
I think the difference in the premium plus and premium , is the amount of PAO. I'm not sure the ad-pack is that different.
@High Performance Lubricants may can explain.
Then again neither am I lol
How many more 10's of thousands of miles engine life will AMSOIL Signature Series, Royal Purple or HPL going to give you over say Quaker State or Mobil 1 on sale with a rebate?
Well that depends imo. OCI of 5K miles? Probably not much. If one is looking to extend intervals to the higher OEM recs or beyond, maybe quite a bit. Not sure what a rebate has to do with extending engine life
Yes, I believe base oil composition along with VII type are the differences

What's your OCI plan?
What equipment do you run it in?
What environment?
What are the drive cycles like?
If you're like many boutique oil users, it won't matter because you're probably already wasting it by changing way too early anyway.

Makes the oil cheaper try to find much of a sale or rebate on AMSOIL Signature Series, Royal Purple or HPL
Honestly, Royal Purple, as it is now formulated, under new management, is a step down from AMSOIL. It may be your choice, but it isn’t what it used to be. It’s made more cheaply, isn’t designed for extended drain, and has little to recommend it ahead of something like Mobil 1. Save your money.
