topaz, - not to drag this out - but I'm happy you're happy with your choice in oil.
but to assert this is a better oil when you have no data to purport that other than just "that's how I feel" is what is probably causing the reaction you're seeing here.
Anyway, you wrote "Simple math here...." - but you actually haven't given us any math to go on...
It sounds like you made a purchase decision on this oil, and you want to share that with other readers - that's fine. But I think in order for you to share that this is somehow "better" oil will require more hard data.

I agree with everything you said, and unfortunately I don't have any hard data to back up my statements. I won't be getting any either as I don't plan to get any analysis done on the oil as I will most likely be selling the car come spring.

To the OP; The absolute end all motor oil for the 996 is JG DT40. It has real research and proof behind it done by none other than the most recognized M96 expert in North America, Jake Raby and Flat 6I. Dont BS yourself or anyone else about some miracle crap oil. You wont understand squat about oil for the M96 until you read JR's info.

I never said it was miracle oil, and I have read JR's information on the subject. Good read.
Did anyone actually have a problem with m1 on this board ? It's relatively cheap and easy to find. Oc interval is more critical. If total is Porsche approved knock yourself out. But French oil in German car ? Indie might just be using since cheaper / higher margins for him than m1 ?
I really enjoy these oil threads I work for one of the large oil companies ( i wont mention which, and i am not in the lubricants department) and this sort of debate I personally thought had died in the 60s. Oil/fuel makes a difference at the very highest levels of motorsport, F1, indy cars etc. In my personal view the manufacturer will spec an oil viscosity/synthetic etc for the engine requirements and general performance matrix. if the oil spec is 0-40 it really isnt going to make alot of difference what bottle it comes out of. Similar to 40% alcohol. a shot of 40% vodka is going to much the same to you as 40% whiskey. Yes i know this is a whole other argument. but my point the spec is the same, and function is the same. Or 100 octane fuel from one or the other retailers.
In my particular oil company the selection of oil from a Car manufacture is generally managed by marketing or b2b. Not the car labs performance centres. Its not hard to see which car manufactures have a contract with which oil suppliers, porsche - exxon- mobil, Ferrari - Shell, Merc- Mobil or Total depending on what car and sponsorship deal. Yes there is different spec oils from all these manufactures which may aid certain aspects of that engine design, but really is a high performance ferrari engine really that different to a high performance porsche engine that a particular brand is better. Spec of oil is much more important then the brand.
To further explain my logic. There are refineries for all super majors, some of them shared/JVs some of them do have IP tech. But they all trade(for gasoline the oil barrel has been traded around 30x before you buy it) additives are added before they reach retail stations to differentiate. Do you really know which refinery made your bottle of oil? yes it will be made to manufacture tolerances. but original oil/feedstock could be quite varied and refineries quite operationally different.
A good quality refined oil from any of the majors and some independents that matched the manufactures specifications, or enhanced specification from a race team/ engine builder will work. dont get me wrong i am not suggesting putting olive oil into your engine. look at the spec, and logically ask your self is this any different to mobil, helix, total etc. Should i pay more for the bottle.
I buy the best oil at the best price and less worried about the brand that sold it to me. I however will continue to enjoy the oil threads
I switched from m1 0w40 to LiquiMoly (on Amazon) 5w40 and it definitely cut oil consumption for my California climate 75k mile 996 in half - having said that never had a bad uoa with the m1 - including after running it at the track. I think the key is also to change oil more frequently than Porsche recommended interval - depends how you drive as to how often - but I wouldn't go over 10k ....
Both my Boxster and 996 use virtually no oil between changes.
The 996 get changed at 5k and the Boxster at 5k unless it has > 2500 miles and I am going to the track and then I change it before the track weekend

i got my car at 55k miles
and it was always using 1qt for 1k miles - which apparently is in spec - yep change oil at 1 yr/5k - LiquiMoly is not much more expensive on Amazon and cut that consumption by at least a 1/2 ...
A30/VW504 & MB 229.51 are the two Mid SAPS specs, but usually come in 5w-30, with the notable exception of Mobil 1 5w-40 ESP, found at VW dealers used in TDi
I made a chart specific for you guys. As you see, MB 229.5 exceeds A40, and A30 being even better, but needing low sulphur gas to do it.
There's two oils to consider, one costs double the other. Also maybe consider Castrol 0w-40 with a host of mfg specs and the new titanium dioxide nano additive. It gets worked into the engine block's metal lattice. I believe this is a must-try product.
I have these old Porsche temp graph I'll throw in as a bonus...

My car burned the DT 40 faster than any oil ive used, by far. The best oil I've used is Motul.
