0w-40 Mobil 1 is their best oil IMO.


I don't doubt it's their best oil. I wonder if it is their most expensive to produce as well?

Are the zinc and phosphorous levels the only thing that preclude it from meeting GF-4 /SM?

Can this be used in a '95 Toyota Camry safely?

Being a 40wt is enough to prevent it from being GF-4. >30wt cannot be GF-4

I switched my X3 truck from 0W-40 to 5W-40 TDT to see if the UOAs look any better. That said, the 0W-40 does fine on an OCI of around 8,000 miles. I still run 0W-40 in the Club Sport, and I've had no problems with it in that application either.

5w-30 Havoline Syn is thinner in the cold than Mobil 1 0w-40


5w-30

0f=426
-10f=858
-20f=1937

0w-40

0f=571
-10f=1127
-20f=3046

A lot of misunderstanding on this issue.

When people see that "0w" they start assuming things.

I'm using it in both of my cars, '05 Opel Astra Wagon 1.8 and '96 Audi S6 2.2 Avant, since it has the right approvals from GM and Audi/VW.

I'm currently 4000 mi. into a run of M1 0w-40 in my SRT-4.
I usually run a 5w-30 but last time was Brad Penn 0w-30.

The only difference I notice is the pcv catch can is filling up extremely fast (every 1000 mi) with the M1 where the last fill took the whole oci (5000 mi.)

That, and it won't meet GF-4 starburst fuel economy requirements.
