Today's motors are bigger, lighter, and more create more horsepower per cubic inch than previously, and hold less oil quantity, stressing the motors oil to the max.
Horsepower increasing additions like turbocharging and charging are very common location. Insert in stricter emissions controls together with all the stop and go cruising common in today's congested cities and you've got working conditions which are overburdened to the cars motor oil.

So what qualities does motor oil need to have to be able to survive these conditions and still provide proper protection? As they say, "the devil really is in the details" when it comes to a properly formulated motor oil.
We'll start with issues dealing with viscosity. Good motor oil must be able to maintain a constant viscosity when exposed to temperature changes. It is also very important that the oil be able to maintain its proper viscosity for the entire duration of its intended drain interval.
A oils pour point tells you how well it handles cold temperatures without gelling (solidifying). Oils that contain too much paraffin; a wax found in petroleum motor oils tend to gel at low temperatures.
Oils with poorly designed additives or low-quality viscosity index improvers will also have this problem. Modern engines have tight tolerances and need engine oil to flow quickly at low temperatures to minimize wear at startup.
