We put motor oil in our engines to serve several purposes. First, obviously, oil acts as a lubricant. If your engine is operating correctly, there is almost no metal to metal contact – everything is riding on a thin film of oil. However, oil has several other important jobs to do. Oil circulates throughout your engine, and cools parts that cannot get near a water jacket. For example, it’s becoming common in sport bikes to spray oil on the underside of the piston to cool it. There are no water jackets at all in your transmission. Motorcycle transmissions are oil cooled.
Your piston rings do not do a perfect job of sealing. Some combustion by products will slip past the rings into the engine. This can be little particles of carbon. Remember, diamond is carbon that was combined under heat and pressure. These little carbon particles can be quite damaging to your engine. Another job of your oil is to hold these particles in suspension until the oil filter can grab them. Also, if your gasoline has sulphur in it (it does), this sulphur can react with water and oxygen to make sulphuric acid. This is some stuff that is seriously bad for your engine. Your oil has special ingredients in it called buffers to neutralize acids. Finally, your engine can get internal build ups of tars, waxes, and other gunk. Your oil has solvents to try to dissolve this stuff and get and keep your engine clean.
Motor oil brands
There is plenty of motor oil companies out there to choose from. It can be a difficult task to pick which one is the best. Everyone has their own opinion about brands of motor oil. There are a couple of things to consider when choosing motor oil.
The history of every oil company should be investigated before you decide to use their oil in your vehicle. Vehicles are one of the most expensive investments of your life time, and the oil you choose is the life of your engine. Several oil companies have bad reputations for things they have done in the past regarding their oil. Some companies have used bad mixtures, inadequate lubrication properties, faulty chemicals, and other neglectful choices that lead to harm of your engine.
Credibility of the oil company you choose should be on the top of your list. Consider using the major oil companies that racing teams use. Racing teams should be your first indication of the quality of the oil you are considering to use in your vehicle. Of course there are the big name teams supporting garbage oil, but look into amateur racing teams and see what they say. These teams are on very tight budgets and will only use the best oil possible.
Also, talk to other car enthusiasts that have turbo forced induction vehicles. Owners of turbo cars that take special care in choosing oil will always know what the best oil to use is. Turbo forced induction vehicles put oil to the test by the heat created. If oil can withstand a highly tuned turbo vehicle, it’s a good bet it’s safe to use in the average car.
The market situation and current economic problems can cause oil companies to short change the consumer by adding chemicals that reduce the amount of oil per gallon purchased. This increase of additives reduces the life of the oil by creating more molecules that are susceptible to thermal breakdown and degradation. Larger companies aren’t always the best choice, because the bigger they are the harder they fall. When times are tough, all businesses tighten up and secure profits. Don’t let your motor oil become a victim of profiteering.
I drive a turbo forced induction vehicle and have been conducting research about oil for several years. It is my opinion that “Mobile 1″ full synthetic is the best motor oil for the money while “Royal Purple” synthetic is the best motor oil over all. Royal Purple synthetic is chosen by several racing and rally teams as their lubrication of choice. Mobile 1 is a highly regarded racing lubricant used in all forms of motor sports. The big guys choose Mobil 1, while the small racing teams and avid sports car enthusiasts prefer Royal Purple. If you can afford the Royal Purple, get it.
Either way, I strictly prefer synthetic oils over conventional and blend. Synthetic oils are made in a laboratory and therefore as close to perfect chemical composition as possible. Less amount of additives in synthetic oil also create a more stable lubricating product than that of counter parts containing several additives, detergents, etc. Synthetic oil also does not create as much energy strain on the environment because the oil you are using is not pumped out of the ground; it’s made in a lab.
