Amsoil Signature Series & GF-7

[buster]

Per Amsoil Magazine:

"....Amsoil Signature Series is undergoing a revolutionary reformulation that promises to usher in the next generation of motor-oil technology."

For the Amsoil Extended Life, Amsoil High Mileage and Amsoil OE - already meets or exceeds Gf-7 and SQ standards.

Just an FYI. I was curious if/when Amsoil was going to reformulate Amsoil Signature Series.

When was the last time Amsoil Signature Series was reformulated?

I hope they do not mess with the NOACK numbers on their 5w30 and 10w30 oil. I will be copying down the numbers tonight! I have no use for the other weights!

2018 or so when they went to SN+ then SP. Not much has changed from what I can tell in at least 6 years.

"Revolutionary...."

Interesting. I’m old skool . Hope it’s not too revolutionary…

I know Amsoil doesn't half azzz anything, I’m sure it’ll be amazing! Hopefully they have a whole new sequence of testing beating the highest industry standards by even more!

I’m in love! j/k but it’s gonna be good. I trust Amsoil.

Wonder if their testing capacity combined with data from their partnership with Lingenfelter is going to make the Signature Series line even better.

Castrol has shown us that it is possible to develop a 25K mile extended drain oil (with the help of their additive suppliers) while maintaining GM and MB approvals. So, it'll be interesting to see what a "modern spin" on boutique oils will look like.

Amsoil has been modernizing their entire line-up and formulation strategy in recent years. I'm really curious to see how far they will push the boundaries this time since they have historically avoided API and OEM licensing on their signature series line.

I'm currently running AMSOIL Signature Series 0w20 in the new Pilot, but seriously thinking of switching to HPL Premium Plus PCMO. I've used Amsoil products for almost 50 years. From what I've been able to find related to HPL, they are quicker to incorporate the newest additive advancements and often have even more robust packages.

The amount of experience and wisdom on this forum is staggering and I'd appreciate hearing your thoughts on using one over the other. Thank you.

Both are amazing oils and most likely the best money can buy. HPL is very open with base oil/additive selection, Amsoil has a warranty they back up and chosen by Lingenfelter after testing the best oils available. Tough call.

And ultimately, it’s about the performance that matters the most.

Roughly Q4 of 2017.

A lot has changed since then. That's why I'm curious whether or not HPL may be quicker to incorporate the newest additive packages... and whether it truly matters between these two products.

I would not be so sure of that. I mean that might be the latest time they announced it. I can't read the whole article, but this does not mean there were no changes or tweaks since 2017.

With how well amsoil already performs in their engine testing, im curious to see what will be improved upon

That's the keyword. It performed well in the tests that were important to Amsoil, which may or may not align with what OEMs desire.

I look forward to seeing what they do. They always put out a quality product in whatever they do.

If you truly think about it. No other company in the oil business is as scrutinized.

All the “scamsoil” guys would pounce if they ever put out an inferior product.

I’ve usually been a Valvoline guy but will change for fun (current fill is Castrol Extended) and use only Schaefer’s in my diesels but I do use Amsoil occasionally.

I’ll be one of the first to try the new stuff

March 2026 rollout for the new Signature Series!

I confirmed with Amsoil via email. No other details.

Is this to better match their SS oil to the quality of their filters?
