Such as? Going thinner doesn't concern you for wear/protection?
Such as 0w30 Mobil 1 and no I'm not concern for wear...
If there is one thing an owner has control over its the viscosity of their oil...
viscosity of oil is rated in ctS which describes a fluid's resistance to flow... it ain't
a thinner or thicker measurement of the molecular size of oil... if you think of oil as
freer flowing or not then you can judge the benefits of a 30wt over the 40wt which are:
1More HP to enjoy because there is less oil drag...
2Lower operating temps because the oil flows more...
3Less wear at start up because the oil pumps quicker...
4)The higher flow works harder to separate the engine parts that are
under very high stress because the relationship between pressure and
flow is in opposition. If you change your oil to a thicker formula the
pressure will go up. It goes up because the resistance to flow is
greater and in fact the flow must go down in order for the pressure to
go up. They are inversely related. Conversely if you choose a thinner
oil then the pressure will go down. This can only occur if the flow
Less flowing oil DOES NOT automatically provide better wear protection
than freer flowing oils. Extensive dynamic wear testing under load of
dozens and dozens of motor oils, has shown that the base oil and its
additive package as a whole, is what determines an oils wear
protection capability, NOT its viscosity. For example, some 5W20 oils
have proven to provide OUTSTANDING wear protection, while some 15W50
oils have only been able to provide MODEST wear protection. So, do not
run so called "thicker oil" under the false assumption that it can provide
better wear protection for our engines.
