Is this really that different from other M1 Products?
Isn't sulfated ash for other M1 products around 0.8%?
Yes SA is about 0.8% in dexos1 Mobil1 oils too.
M1 ESP 0w20, 0w30, 0w40, 5w30 oils all meet higher tougher German oil or Corvette specs, although Mobil1 Annual Protection 0w20 is all-PAO anyway and might come very close to M1 ESP x2 0w20 in performance, but we don't know for certain.
Very good VI. Do you have a link where this oil can be purchased?
Google shopping says SunCoast Porsche website sales, and ebay sometimes has some. Maybe local porsche dealerships use it too. I might start getting that oil later on for my VW 508 application.
Like JohnnyJohnson above, Google Shopping is also ignorant about the diffs between M1 EP and M1 ESP, so both appear in the shopping list.
Make sure you get the ESP one. I read a post the other day where a diesel Mercedes (almost new car) owner used M1 AFE 0w30 for years without knowing or caring if its the right oil.
