We have already discussed the positive effects on fuel economy that synthetic motor oil and transmission fluid have. Now we will touch upon their other positive effects, namely increasing horsepower and torque, reducing operating temperatures, and long service life.
Synthetic Motor Oil
As mentioned in the motor oil for fuel mileage section, synthetic motor oil can increase horsepower by reducing friction between the moving parts of an internal combustion engine. This includes but is not limited to the cylinder wall to piston interface, camshaft lobes, engine bearings, and valve springs. The smaller, more uniform molecules of the synthetic oil provide increased lubricity to motor parts allowing them to operate more freely. Increased torque and horsepower to the drive wheels is the result.
Synthetic motor oil also has the ability to dissipate heat away from engine components more effectively than regular motor oil. The smaller oil molecules allow heat transfer to occur at a quicker rate than with standard motor oil keeping the engine cooler. This will reduce wear in the long run that is caused by temperatures that put additional stress on engine parts.
