I suggest using a low cost oil so that changing it doesn't hurt financially. Then problem solved well enough.
two samples...same pilI don’t know what you’re asking. Mechanical shear of the VM is dependent on several factors.
It depends on shear forces and specific circumstances. Most engines do not tend to shear the VM.two samples...same pil
one with fuel dilution
one without
krl test........
which one shears more?
what is VM?It depends on shear forces and specific circumstances. Most engines do not tend to shear the VM.
But also in general the presence of fuel is detrimental to the VII in the oil. Use an oil with no VM and there won’t be any shear regardless of fuel.
The viscosity modifier, or VII.what is VM?
Magicwhat is VM?
So if there is no VM, then fuel has no effect on shear stability?The viscosity modifier, or VII.

Do most common off the shelf brands use VMs?
Which do not?
HD30/hd20 and some 10w30 full synthetic oils.So if there is no VM, then fuel has no effect on shear stability?

I am not sure of what this means.The search function shows this:
It’s still in sump of my dad 11’ Focus with 98k on it. No consumption at all. Better than restore and protect think. Least I know what I’m buying
No, there is nothing to shear. Oil molecules will not shear in an engine, the shear forces are nowhere near great enough to do this.So if there is no VM, then fuel has no effect on shear stability?

As normal, I am misunderstanding something. Please help me understand.No, there is nothing to shear. Oil molecules will not shear in an engine, the shear forces are nowhere near great enough to do this.
As noted, nearly all oils use VII except monogrades and a couple muti-grade oils that could also be labeled as a monograde. But the shear stability is dependent on the quality of the VII as well as the tendency of a specific engine to cause shear.
Fuel dilution is essentially a lower viscosity fluid being mixed with one of a higher viscosity. If there is fuel in the oil then it will lower the viscosity of the oil just by being there regardless of whether it is a monograde oil with no VII or a multi-grade.As normal, I am misunderstanding something. Please help me understand.
If a motor oil starts off at viscX, and ends at viscX-1......that is due to viscosity modifiers "losing a battle"
If in an engine oil does not make oil shear, then what causes the viscosity to change?
Is it the fuel "attacking" the VMs and not the "oil"?????
Why not stick it in a pot on the stove for 20 minutes for the fuel to evaporate? Right next to the Christmas gravyWhy not just drive aggressively to build oil temperature to 220-240?
