How To Choose Car Lubricants

Car lubricant is an essential component of your car's engine. Not having any oil in your engine will result in having a "knock" in your engine - if the engine is too dry, the moving parts inside will scrape against each other and ruin the engine completely. These days, physicists are constantly developing new types of car lubricants to satisfy the needs of today's more demanding automobiles, as well as answering the need for a reduction in harmful exhaust emissions. These lubricants keep the engine from rusting out, control friction within the engine, protect the main oil, and keep your engine's pistons cool. How do you choose which car lubricant is the best for your car?

There are three major points to consider when choosing lubricants for your car. You will need to take note of your car's age, the type of car you are driving and of course, your own personal style of driving. These three factors have a direct impact on the daily wear and tear that you subject your car's engine to.

Higher-grade lubricants are thick and viscous. The lubricant will be working in a high temperature, high pressure environment, and the right lubricant must be able to withstand the heat and oxidation, giving the metal parts of your engine a thick protective coating. Lubricants fall into two major classes, monograde or multigrade lubricants. An SAE rating, from the Society of Automotive Engineers, classifies these lubricants. You may encounter lubricants that are labeled SAE-20W/30 monograde. The first number is a measure of the lubricant's viscosity or thickness at low temperatures, while the second number measures the lubricant's viscosity at 100 degree Celsius. To put it into practical terms, you are looking for a lubricant that is thin enough at low temperatures, such as when you are starting your car in the winter, and thick enough at high temperatures, such as when you have been running your car engine the entire day. A good lubricant is able to adjust itself to both the temperature within the engine and the external climate factors in your area that affect your engine as well.

The use of lubricants is not confined to the engine area alone. Lubricants should also be applied to your car's gearbox. Like the engine, the gearbox is also one part of your car that involves moving metal parts at high temperatures over a long period of time. More often than not, the lubricants for the gearbox are only applied once, and this should be enough to provide a lasting coat to protect the gearbox from wear and tear. If you are unsure as to whether or not your gearbox needs a new coat of lubricant, speak to your local mechanic and have him assess the situation from a professional standpoint.

Car engine lubricants have definitely come a long way from a few years ago. Along with bigger, faster engines came the demand for better synthetic engine oils and lubricants. Apart from what was initially discussed, it also wouldn't hurt to make sure that you get outside opinions, as well, on which type of lubricant would be best for your car.
