Choose the right oil

Woooow ..! Hello my visitors! how are my visitors? certainly fine,, been 3 days I did not write an article on my blog, maybe you will be disappointed with this. no problem, in my explanation, I will write about how to select motor oil properly and appropriately . well, hopefully with my post today, all my visitors can be excited and happy! :) :)
In general, we assume that the main function merely as an engine lubricating oil. Though oil has another function that is not less important, namely, among others as a coolant, protection from rust, Cleaning and Closing Gaps in the wall machine.. The following explanation :

1). Consider packing lubricant
Buy a lubricant that is packed with good, still sealed with neat, there is a corporate identity and purpose of use. Avoid buying goods that are defective packaging. Buy a lubricant on the official agent or in places that can be trusted by you or recommendations from your colleagues ... Now you are certainly more aware than ever about the quality of the oil. We recommend that you use oil that has the highest API certification because it will give better results for your vehicle from either side of the vehicle performance and maintenance in the long run. Synthetic oil is more expensive than mineral oil but we can choose a semi-synthetic oil is better than more economical than the mineral and synthetic oil. 


2). Note the clue "SAE GRADE" on the packaging of the oil
Grade Lubricants are divided over singlegrade / monograde such as SAE 15 and SAE 50 (used at extreme temperatures) as well as multigrade SAE 5W-50 and 15W-50 is widely used (except at temperatures very hot or very cold) because the lubricant is sufficiently dilute to flow at low temperatures and thick enough to work satisfactorily at high temperatures.
More precisely we use the following illustration:
There are 3 oil, a multigrade, 2 monograde
An SAE 15 oil (diluted)
2 Oil SAE 50 (thick)
3 SAE 15W50 oil (multigrade)
- Oil was taken third place cold temperature then:
An oil (SAE 15) will be more viscous because of cold
Oil-2 (SAE 50) can be frozen because of origin has been condensed
Oli 3 (SAE15W50) Oil viscosity is equal to 1 (SAE15) 
- Now all three were brought Oli to a hot temperature, then:
An oil (SAE 15) becomes very dilute and even can evaporate all
Oil-2 (SAE 50) becomes more dilute
Oli 3 (SAE 15W50) Oil viscosity equal to 2 (SAE 50).

3). Select the proper viscosity lubricant
Lubricant viscosity level which is also called "Viscosity-Grade" is a measure of lubricant viscosity and the ability to flow at a given temperature. Oil is a form of identification code letters "SAE" which stands for the Society of Automotive Engineers. Furthermore, the numbers that follow behind, showing the level of oil viscosity. SAE 40 or SAE 15W-50, the larger numbers that follow the Code of oil, indicating that the more viscous the oil. The letter W is contained behind the initial digit, stands for Winter. SAE 15W-50, means the oil has a viscosity SAE 10 for the conditions of cold temperatures and SAE 50 in hot temperature conditions. With these conditions, oil will provide optimal protection when the engine is turned on even extreme conditions. While it is normal in hot conditions, oil will work ideally in the range of 40-50 viscosity number according to SAE standards.

So, this just might be that I can write in the post today. hopefully it all worthwhile and a reference material for you all,, And choose a nice oil according to your own choice, do not vote because coercion of others, a good choice is the choice of successful people!
