Mobil 1 ESP (SQ rated) 0W-30

Interesting to note: High Boron, Excellent Flashpoint...Low Magnesium though! Comments on Oxidation and Nitration?

 

[GW.]

Thanks. Formula remains unchanged. Oxidation of 45 indicates ester.

Nice looking numbers right there……..glad to see the “Bean counters” didn’t play with the formula and kept it as is

It just occurred to me...This oil (even its viscosity range) is targeted to European vehicles. It has German automaker approvals from Porsche, MB and VW. If I remember correctly, it is illegal in Germany to label an oil as synthetic if it contains Group III base oils. This would leave Groups 4 and 5 to market an oil as 100% synthetic. The Germans - don't mess with their beer or their engine oil - they have to be pure. So that might explain partially why the base oils in ESP 0W-30 probably consist of primarily Groups 4 and 5 base oils.

Perhaps someone that understands current German laws can correct me if I am wrong.

This oil is not "API SQ Rated" It does however pass all API SQ Engine testing requirements.

Not sure. But this isn’t Germany, and things get different packages and labels depending on where it’ll be sold.

 

[Marcozi]

You are correct. In Germany an oil can be labeled as "synthetic" only if the oil's base stock is a group 4 or 5. Check out the German LiquiMoly website. Nowhere does the website say "synthetic."

Great oil readily available.

Looking at the VOA makes me excited to try this oil out on my next oil change in my Fiesta ST.

What specifically gets you excited?

Not anything to do with the VOA, but it’s good to see the numbers. I haven’t used a high end euro spec oil in my fiesta ST yet and I’ve heard only great things about this oil. I’ve been using the black bottle Castrol edge 5w30.

Added to the VOA Database. It does look the same as VOAs from 2023 and 2025 so @incognito_2u is spot on with his assessment.

The viscosity is low at 11.?? Previous reports including Mobil 1 data sheet it’s 12.2 @100c

Viscosity can vary from one batch to the next. Also, Blackstone is terrible for accuracy

0ppm chromium got me just rockin this morning

Thinking about this for my hemi ......

Is that Calcium level too high for a small turbocharged engine?

No. Passes all SQ engine performance tests including LSPI.

The boron is probably a borate ester, which is also showing up in the high oxidation.

I’d personally like to see more Mg, but an oil is a complete recipe, not just a handful of ingredients. Mobil knows what they’re doing.

I was too worried about that a month or 2 ago when changing the oil in my 2.7 Silverado and went with the ESP 5w30.

I hear over and over again how Calcium causes LSPI and the fact that it was API SL worried me.
