Change the Oil in your Automobile: Which Oil to Choose?
When you have a car sooner or later you face the problem of oil changing. You might have already heard that there are quite a number of oil types. So, the questions are the following: what oil type do I need and how to change oil?
One more thing that might puzzles you mind is whether each car needs a different type of oil. And if you go to autozone, will they help you?
Oil change issue becomes even more acute if your car has been standing idle for some time. The other day I’ve read about a man who wanted to change oil in his car which has completely run out of it and has been standing idle over 7 years.
The folks advices him to flush out the engine with 10w30 oil and engine flush if he can start the car. They said that all oil (plus antifreeze and brake fluid) should be flushed through the system.
But it didn’t resolve the oil question. Which oil to use? Some say it is 10w30, the others stick to 5w30. So what is the solution to the problem?
In fact, the solution is the nature of oil. All conventional oil comes from…the ground. The major difference between different types of oils is what kendall puts in it thats different from castrol, valvoline or the generic stuff. The things that makes one kind of oil different from the other are additives and detergents. The viscosity rating (those 10w30/5w30 numbers etc.) basically Is the realitive thickness and slipperiness of the oil in cold and hot temperatures. Actually they show:
- How well the oil behaves in a cold engine
- How well it behaves in normal conditions
- How well the oil holds up/breaks down under high temperatures
One can find dozens of comparing charts that show where one weight fits compared to another. Most new cars come with the recommended oil 5w30, because the temperature range fits the temperature range of the whole country. For instance, 10w30 is for the hotter climate.
Another aspect as the wear of the engine has to taken into consideration. If your engine has high wear then you’d better choose a thicker oil like 10w40 or even 20w50.
Synthetic oil is another story. From the beginning of the manufacturing process it is engineered. It is made so that you could have a lubricated start up. At the same type this type of oil is a little more slippery than the conventional.
As for the above described situation, 10w30 seems the most probable way out.
As for autozone cooperation, I think that they will be very helpful.
