Motor Milk - new boutique?

Thank you for responding! I also prefer the “old school” performance based formulas utilizing PAO and Ester.

One thing BITOG really likes is transparency from a blender!

What percentage of PAO and Esters are you guys using?

Any other base oils like GTL(group 3) or AN’s being used?

Thanks again
yea let's get the popcorn out.

Mobil 1 gives you a 5 quart jug for the cost of their quart. Sorry at that cost it would be prohibitive for me to even consider.
figured this would come up again, try something new, think outside of the usual box, maybe this new oil is good in its perspective intention as Euro cars. hmm?

Transparency is nice. But for now, all things and price considered, I got more faith and higher chance of actual usage of HKS 7.5W-55.

Jk. On a slightly more serious note... If you guys at @Motor Milk actually mean it, then there are a few data nerds 🤓 on this forum, that supply tons of useful data for the rest of us. @TiGeo comes to mind, if he's willing to track/daily test the Motor Milk in the VW.
 
Hello Glenda W.,

Thank you for your kind words and for welcoming our response. We appreciate it. There is no need for the grasshopper emojis; we understand your insinuation there. Rest assured, we are just not as active on the forum here in Europe.

To answer your question: both yes and no, as it depends on the viscosity grade. For most of our products, we use esters and polyalphaolefins. However, for our 10W-60, for instance, we have not yet identified a formulation that allows what we consider to be the most advanced ZDDP package to fully dissolve and remain stable in our purely ester/PAO base oil system. Given that our core clientele is heavily focused on track-day driving and performance tuning, we place particularly stringent requirements on ZDDP together with viscosity control and thermal stability. The trade-offs when trying to pack an authentic additive package whilst striking a perfect balance between maintaining stability and racing/tuning viscosity specs continue to fascinate and intrigue us. This is not a new phenomenon, as you will know, and explains why essentially all other producers in this space have to rely on some Group III chemistry (to far greater extents/percentages than we do). That said, we are currently developing a new product range, and we expect that even the 10W-60 will eventually move away from its current low Group III base-oil content. All of our base stocks are sourced from the world’s leading suppliers. We have compared many to find the highest-purity ones as they arrive at the Port of Rotterdam!

We believe we have achieved really awesome formulations, and thus we are proud to share as many product characteristics as we can validate through third-party validation. Some here have already pointed out that we disclose much more data about our formulations than most conglomerates do. We'll continue to do so!

Thank you again for your interest.

Kind regards,

Günter @ Motor Milk™

For the record, someone claiming to be from Motor Milk reached out to me and offered me some of their product for free via DM. I would like to reply here first since this thread is the most relevant.

We would nevertheless like to address your new accusation. There is nothing opaque or improper about our company.
Some free advice and maybe some clarifications.

First, your pricing is astronomical. Sure your blender is pricey, whatever. If you can't meet the market, you're going to fail. At $207 to get 6L of oil to my door, that is higher than literally every other boutique oil I'm aware of, even before tariffs. Driven, HPL, LAT, Redline, even Motul or Ravenol. I get that you don't have the volume they do, but you also don't have the proven history those brands do in terms of years and years of sponsored cars. When I made my comments, you didn't have a single livery.

Second, your english product data sheets mention "approvals" which they obviously have none. Which makes sense, they are race oils. But listing them, particularly as "approvals" is a standard shady move by boutique labels that puts people off.

Lastly, (and maybe most importantly) your website has zero info that gives me confidence in your credibility as an oil blender. No pictures of the founders, no names of the founders, no credentials. All I know is your first name from these forum messages, which is still not enough to verify whether you or your partner actually have a PhD in a relevant field.

From your website: "Our CEO first recognised these troubling trends toward the end of his PhD studies and decided to act."
Did he finish the PhD studies? What field were they in? Where was this? Who is the CEO?

Looking up the Sebastiaan E J Asselberghs authoring your blog posts, I see someone in the netherlands who appears to have an studied for a PhD in vascular pathophysiology that lines up with the timeline.

If that's the same person, I understand why your site leaves that vague, but personally I find this rather discouraging, with extremely ambiguous wording letting the customer assume you have a PhD-credentialed chemist or tribologist on staff when it appears that your CEO failed to finish a medical-related course, and then pivoted to selling the most expensive engine lube on the planet while also running a burger joint! Humble beginnings indeed!
 
I think we are a little too harsh on them. Starting a new venture is hard, and it is understandable to make mistakes. Listing "approvals" the oil does not have is one. The terminology we use is "recommended for" if the product is not officially approved but you have confidence that it would meet or pass the requirements of a certification. Though a track oil does not really need one. I use motul 300v for track usage on my gr86, and I don't think they list any single approval (besides, it is not a good street oil anyways).

Good luck with your new venture. The pricing is really steep, but if you are marketing your product as a luxury good, that might even help you with higher sales, especially considering a brand recognition is lacking at the moment. What I usually see at that point would be launching a Halo line that is really expensive and high performing, which creates a good decoy effect for the main tier
