The SHC Formula LA is primarily formulated for MB while Mobil 1 ESP Formula is Mobil's new "top-product" for European car requiring low-SAPS oil.
I have seen Mobil 1 ESP at 70 Euro/4litres at the warehouse.
Most of people who buy these new cars do not change their oil themself, so it does not matter to them whether they pay 15 Euro/L for regular M1 or maybe 20 Euro/L for ESP at the dealer.
Primus, ESP will work in "older" engines, but not better than for example regular M1 0w-40. I think low-SAPS oils are waste of money. Again, deposits created by some additives are only an effect of (high) oil consupmtion. Even in a new car, I would use a "normal ash oil" (provided it shows low oil consumption), rather than a new untraditional and expensive oil.
The last 20 years (or more) oil companies told us to use their premium engine oils with, typically with 1,2 - 1,5 % sulfated ash content. New cars/engines (especially the exhaust gas aftertreatments) may require different oil technologies. Hence, changes in oil technology are basically no longer quality enhancing.
I don't know about oil pricing in Ukraine. Compared to The States, most of the known PCEO's are overpriced here in Germany. If you need a good Xw-30, consider Castrol SLX 0w-30.
Sorry, only my opinion.
