Different oils have a different thickness and this is also known as ‘viscosity'.For example, a viscosity rating on a bottle of oil might be written as 5w30. The ‘5w' refers to the thickness of the oil while the engine is cold - the lower the number the better.
The ‘30' refers to the thickness of the oil at operating temperature. The lower the number, the more efficiently your car will run.
Other types of oil
As well as looking at viscosity, you'll also need to know about the different types of oil that are available:
§ mineral oil - basic protection for older cars.
§ part synthetic oil - a good in-between oil.
§ fully synthetic oil - the ultimate in engine protection.
What does Engine Oil do?
Your engine oil performs many functions. It stops all the metal surfaces in your engine from grinding together and tearing themselves apart from friction, and it transfers heat away from the combustion cycle. Engine oil must also be able to hold in suspension all the nasty by-products of combustion like silica (silicon oxide) and acids. Finally, engine oil minimises the exposure to oxygen and thus oxidation at higher temperatures. It does all of these things under tremendous heat and pressure.
When must I change my engine Oil?
Manufacturers typically recommend that you change engine oil at least once every 7500 Miles. However, this is based upon optimum driving conditions. However , if you do a lot of stop-and-go driving in city or rush-hour traffic, make a lot of short trips each day and leave the car parked long enough to have your engine cool down between them, and don’t often get up to high speeds on a highway, then we’ d recommend that you change the oil as often every 1,000 to 3,000 miles on older vehicles. On new vehicles, follow the manufacturers’
In conclusion new vehicles can run longer on the same oil than older ones can, and improvements in motor oil have extended its efficiency over longer periods of time, to be on the safe side, you might want to change your oil every 5,000 miles or every six months. Changing your engine oil will vastly prolong your engine life, and we highly recommend doing so.
