Auckland - Wellington In 30 Seconds

Our headline reads like' a misprint or an impossible exaggeralion, but it is strictly true if you, consider it like this. Under certain conditions, more wear can occur in the engine of a car in 30 seconds than would, result from a non-stop trip from Auckland to . Wellington. The conditions are known to the expert as “dry running" and the period during, which it occurs is immediately after starting the engine. A good lubricating oil forms a strong oil film between moving surfaces, which remains even when the ’ engine is at rest. On starting up, this provides a certain amount of protection, but it is not until the oil in the crankcase gets into full circulation that thorough protection from wear is provided. The “dry running” period after starting is responsible for most of the wear that occurs in a car engine, and it becomes particularly seri-' ous during the cold winter months,. Heavier bodied oils used for summer driving become sluggish during the cold weather and circulate too slowly. This prolongs “dry running” and produces excessive wear. The car also becomes difficult to start and a severe strain is placed on the battery. To reduce “dry running” period to a minimum, the Vacuum Oil Company recommends the use of a special light bodied winter oil known as Mobiioil Arctic. It is claimed from tests that ' this oil will give easier starting, a minimum of starting wear and at the same time thorough lubricating protection at all temperatures of engine operation. 1 ;
