June!
New Amsoil formulation?
- Thread starter Klutch9
- Start date
I like the labels more too.
I doubt they will tell us more about the formulation, but I would like to know.
Pablo - maybe send a VOA?
You think it’s going to be API??
Not formally of course but compliant like the last X years
What do you mean by compliant? As compared to being “non-compliant” and stout? Additive levels?
Meeting requirements but not listed as OE and others are specifically listed
What others are listed? You think it will say it meets API requirements??
OE XL HM and Blend
I see it as a niche product because it is optimized for cleaning but makes no claims regarding extended drain intervals. The latter has always been central to the marketing strategy for Mobil1 oils. Valvoline has changed the conversation. Personally I favor an oil that can handle extended drain intervals but others may have different priorities.
I don’t think that’s an accurate characterization. People seem to think that because it cleans it somehow loses other powers or something. It is an excellent API spec oil that also happens to clean and restore your engine back for factory levels of cleanliness. They say to follow your owner’s manual. So if your OM says you can do 10k OCIs then you can do it with VRP. And there have been absolutely pristine, as-good-as-it-gets UOAs with VRP on 10k OCIs.
You are correct in that the extended OCI is Mobil 1’s “marketing strategy.” You are falling prey to the marketing. If you actually go on their website and read the fine print behind that asterisk behind the 20k “guarantee” it says to follow your owner’s manual….just like Valvoline says up front. If anything, Valvoline is just being honest from the start.
What does any of that have to do with a new Amsoil Signature Series formula? I feel like we are way off topic now.
Yes
I don’t think this link was posted yet:

At a glance, seems like they are claiming that the new Signature Series it has it “all” (shear stability, long drain interval, pistons stay clean, etc etc) with the exception that they do not claim to clean existing deposits à la Restore and Protect.

I have the 0w-40 SS coming tommorow for my Daughter's Expedition. But I would doubt it is the new formulation. Did not have the EA oil filter. I just bought the Wix oil filter with the oil.
You had my curiosity. Now you have my attention.
Pablo - any details on the dyno setup? Just highway miles? Or any stop and go traffic?
Heck ya!!
“AA: It is better in every way. Specifically, next-generation Signature Series provides 12.5% better results in Cold Cranking Simulator testing. In the Thermo-Oxidation Engine Oil Simulation Test, the TEOST, it performed three times better than the old formula. In Sequence IIIH, we saw a 16%
improvement in weighted piston deposits versus the old formula, and that’s a big deal. Dealers who have been around for a while know that we ran a double-length Sequence IIIH on the last version of Signature Series and the results were outstanding. Well, we did it again and the results are even better.”
