I'm wondering about the tradeoffs about Mobil 1 5-30 and 10-30.
Since the 10-30 has a narrower viscosity range, would it most likely be more shear stable over the life of the oil?
And since M1 does not thicken at colder temps to the same degree as dino oil, might the 10w at the low end still offer nearly the same great cold start pumpability as the 5w?
How much difference is there between the cold pumpability of these two choices (or even of the 0-30 m1)?
Toyota recommends 5-30 for my 04 camry 4cyl. But this is a broad recommendation that does not distinquish between synthetics and dino oil.
What would be the tradeoffs between using 5-30 versus 10-30 in this car?
Thanks for your thoughts,
Harry
