Study Your Motor Oil

ONE of the new things for owners of new cars to learn is the importance of specifying the right grade of oil for the engine, and of being certain that they get what they ask for. The grade of oil is getting to be just as important a factor as the brand. Top heavy an oil will cause an engine to overheat. In addition to causing overheating too light an oil will encourage bearing troubles.

.Generally, speaking, with the high speed engines of to-day it is more dangerous to risk using too light an oil than one that is too heavy. Oil must sbe heavy enough to stand the higher connecting rod pressure caused by higher compression. If the oil breaks down under the load the situation is just as bad as if the oil was of an inferior brand or as if the quality failed to take care of all needs.
