Why?
I really think that there are some great M1 oils but that’s in their higher tier offerings (such as EP and ESP and the Euro and Supercar stuff). I have no real concrete evidence to back up my feelings here though, it’s more of an educated hunch to be honest. But given the fact that M1s higher tier products are not really all that expensive, I think it’s worth it to go for them over their more entry level stuff anyway.
Many prefer a name brand synthetic over a generic synthetic. There is nothing wrong with the oil from Warren distribution that Amazon, Costco and Walmart all put their name on, but the same probably goes for synthetic oil from Mobil, even the base version. It certainly still meets the criteria to be called a full synthetic, just with an actual name brand and Dexos certification like some other full synthetics, including SuperTech.
It's interesting that Mobil Full Synthetic 5w30 and 0w20 have the dexos cert but 5w20 does not. I wonder if it does not meet the spec or if they choose not to pay Mobil for this grade.
It’s unfortunate, but there is no way you know if the oil had mechanical shear of the VM or how much fuel dilution there is in the sample. They are useless for that determination.
Yeah, I do not discount fuel dilution being a factor but I have used other oils with higher fuel dilution that still stayed in grade.
Then they must have a higher starting viscosity.
Interesting. I would probably use this in my cars calling for 0/5w20 then
I would not “condemn” an oil for viscosity based on a Blackstone UOA.
I like to use 5w30 anyway. Just gives me more reason to.
Yes and pretty similar to the Warren oils (supertech, Kirkland, mag1, etc)
