Oil changes are clearly an important part of vehicle maintenance but choosing the optimal motor oil can be a bit challenging at times. This is especially true for those who have not yet learned to read viscosity ratings. Fortunately, however, this does not take too much effort.

The oil's viscosity when your engine is at a relatively low temperature is indicated by the first number in the rating, and it is followed by a "W". The oil's viscosity while your car's engine is at a comparatively hotter temperature is conveyed by the second number in the rating.

Hopefully, a rating similar to "10W-30" will be much easier to read if you see it on your next bottle of motor oil. If you are looking to put this viscosity rating knowledge to use at your next oil change in Council Grove, KS, then stop by the helpful service department at Bolton Chrysler Dodge Ram Jeep soon.
