Mobil 1 Ext. Performance - SM? | Noria Message Boards

Read our primer articles on High Mileage Oil, Synthetic Oil and Kinematic Viscosity

Awhile back I was told by Mobil that they are working on a GF-4/SM rated Mobil 1 Extended Performance. About a month ago, their lead tech guy said that they are going to continue to make 2 Mobil 1's and that the regular M1 makes up about 70% of the sales.

So, does anyone think Mobil will go back to 1 Mobil 1 again and why havn't they done this to begin with? Cost? ZDDP is cheap so they say....

ISLAC GF-4 oils do not have the phos capped per se ...... It's the API SM designation that denotes a cap on phos .

Was that what you mean't to say ?

I can see that happening but one will take it's place most likely . Maybe like the A3 Euro version in the other thread or 5w-30 Truck and SUV

Thanks Motorbike. I wasn't clear on that. So I guess in time, the M1 EP will be SM and GF-4 rated. P is still too high for SM.

Check this out . Newer oils will do very well with low , low phos . Oils like the Euro Castrol and Mobil , Fuchs will pave the way .
