If an engine lubricating oils viscosity is given as SAE 20W as compared to SAE 20, what is the significant difference between the two lubricating oils? |
A) The SAE 20W oil is primarily designed for year-round (low and high ambient temperature service) and SAE 20 oil is primarily intended for low ambient temperature service. |
B) The SAE 20W oil is primarily intended for low ambient temperature service, and the SAE 20 oil is primarily intended for high ambient temperature service. |
C) The SAE 20W oil is primarily designed for year-round (low and high ambient temperature service) and SAE 20 oil is primarily intended for high ambient temperature service. |
D) The SAE 20W oil is primarily intended for high ambient temperature service, and the SAE 20 oil is primarily intended for low ambient temperature service. |
