AMSOIL Signature Series went UP Blackstone oil analysis report: 10,580-Mile AMSOIL Signature Series UOA on a 2025 Maverick 2.0 EcoBoost MPC (Non-GPF)

While many oils are changing… AMSOIL Signature Series went UP

Been following all the recent oil reformulations and honestly this one surprised me.

Many oils are being reformulated today, some apparently becoming a little more cost driven. But AMSOIL seems to have gone the other direction with the new 2026 Signature Series.

Here is the old vs new Signature Series 5W-30 that I’ll be using in my 2.0 EcoBoost Maverick:

AMSOIL Signature Series 5W-30​	Previous​	New 2026​
Viscosity @ 100°C	10.3 cSt	10.5 cSt
Viscosity Index	162	165
CCS @ -30°C	3968 cP	3791 cP
Flash Point	220°C	242°C
NOACK Volatility	6.7%	5.3%
HTHS	3.11	3.0
TBN	12.5	10.4
API / ILSAC	SP / GF-6A	SQ / GF-7A

The 5.3% NOACK and 242°C flash point really got my attention, especially for a turbocharged EcoBoost My Maverick is now around 38K miles and the engine honestly feels better than ever. Strong, smooth and zero reason for me to change what I'm doing.

I have also changed my thinking a little about oil analysis. Blackstone is still my choice for following the long-term wear trend on this engine, because I already have the history there. But Oil Analyzers I may try them

Next experiment: I'm planning to take this new Signature Series formulation to approximately 12,000–13,000 miles, assuming everything remains normal, then send another sample for UOA.

So... we'll have some real data instead of just arguing about oil on the internet Probably 10 months from now. I'll update this same thread with the results. Cheers








I wanted to share my latest Blackstone report and a little background on this truck.

This is one of the early 2025 Maverick 2.0 EcoBoost MPC engines produced before Ford started adding the GPF. The truck currently has 32,092 miles, so in my opinion the engine is still relatively new and just finishing its break-in period.

Oil history:

• 495 miles
• 4,005 miles
• 8,002 miles
• 10,580 miles (current sample

All oil changes have been done with AMSOIL Signature Series 5W-30.

Current results:

• 10,580 miles on oil
• TBN: 4.2
• TAN: 4.5
• Fuel dilution: <0.5%
• Flashpoint: 440°F
• Insolubles: 0.1%
• Iron: 8 ppm
• Aluminum: 5 ppm
• Copper: 2 ppm

Blackstone’s comments were very encouraging. They stated that the oil held up just fine, wear remains healthy, fuel dilution is not an issue, and there is still plenty of active additive remaining. They even suggested trying a 12,500-mile interval next.

What I find most interesting is that this engine is still very young at only 32k miles. Wear metals remain low, oil condition remains strong, and the trend continues to improve with mileage.

For anyone interested in long-term ownership of the 2.0 EcoBoost, I think this is a useful real-world data point.

My goal is to keep this truck for a very long time, and so far the results have been extremely encouraging.

A 2025 Maverick with 32K on the clock. This works for you and that is great. Me? 2023 Mav with 8.5K on the clock. Whole different world. My oil changes are calendar driven.

I’m not surprised of this BStone report. Why? Your viscosity is low. And BStone hinted of shearing. No fuel in the oil. And flash point. They seem to indicate typical for this engine.

And that of full synthetic oils!

I agree. There are no notable differences here from the prior generation 2.0L Ecoboost in the 2022-2024 Mavericks.

Curious what your OLM had gotten to with that many miles?

But it sounds like nothing harsh in the driving you did?
What season was that during?

Amsoil is a great product.
I have used the oil and their filters in everything I own for over 25 years with ZERO issues.
I change the oil every year or 15k miles whichever comes first, numerous vehicles with well over 100k miles over the years.
Thanks for the data.

Yup. Mine is a 24 with 3K on it. It is just over 1 year old and had its first oil change. Normally would not have bothered, but hope to keep it for a very long time.

Good observation. I also noticed the low viscosity and Blackstone's comment regarding shear. What's interesting is that the flash point doesn't suggest significant fuel dilution. That's why I think trending multiple reports is more valuable than looking at a single sample. PAO/ESTER oils simple-the-best -quality for TurboEcoboost engines

I agree. There are no notable differences here from the prior generation 2.0L Ecoboost in the 2022-2024 Mavericks.

The current Maverick 2.0L is much more than an early EcoBoost derivative. 10-15 years of development can result in major differences in durability, efficiency, emissions performance and lubrication requirements, even when the basic architecture "appears" similar

The OLM was actually at -2% when I changed it 70-80% highway driving, very little idling, no towing, and no heavy loads. a lot of SPORT mode . That's one reason I was interested in seeing how the oil held up from both a wear and viscosity standpoint.

268K on my BMW M54 6 inline engine, and going strong . NEVER a problem . AMSOIL oils are incredible good.

I fully understand. That's a long term ownership mindset, Sometimes an early oil change is more about peace of mind and future durability than immediate necessity

I'm quite familiar with the multiple generations of 2.0L Ecoboosts, the archtectural differences and the advantages and disadvantages of each generational development.

I was commenting on the Blackstone results and their similarity to those from the prior generation that I own. I was likewise not surprised by the results as CajunMick stated, and that is why I quoted and agreed with his post.

There's no need to get defensive. Believe it or not, there are other owners on this site such as myself who do regular oil analysis and aren't out to crucify you for wanting the data and sharing it.

On this forum (our forum?) there is a mild “tension” between Hybrid owners & EB owners. Not sure if “tension” is the correct term.

I also sense a mild tension, sometimes, between the EB owners depending on which generation their Maverick has.

Still waiting to see any “tension” develop between the Hybrid owners towards owners with the new improved eCVT in the latest Gen Hybrid. Major upgrade there to be frank.
