Now the FS version now is available here + old formulation is still on the shelves.
Mobil1 is my favourite one due to its
1. great cleaning effect
2. excellent antiwear pack
3. high HTHS number
4. low cold start viscosity
so I'm curious about the difference before trying in my flat tappet light turbo aspirated 5 cylinders S60 petrol engine (B5204T)
Interesting for me: FS has
1. lower viscosity at 100°C and 40°C
2. lower MRV at -40°C by 30% (!)
3. higher TBN
4. lower HTHS
5. slightly higher sulphated ash content
6. lower density and flash point
So I'm cofused now: is it designed for older or newer car?
Based on UOA shared here: can't keep weel its vicosity after 5K miles UOA: M1 FS vs. Castrol Edge
