The oil makes your car run better with respect to the engine, transmission and engine parts. Is the lubricating fluid that allows all parties to continue working without damage? Given technology, synthetic oil has been developed with better results and a longer life before needing changes in the fluid. In some cases it may take longer than mineral oil (traditional oil based), but in other cases, the rate of change is the same.
Why use synthetic?
Well-maintained vehicles have regularly been able to make up to 200,000 miles (321,868 kilometers) of travel, many of which have been converted into synthetic oil to prolong performance. So the product has proven to keep old cars running history. Given that older engines work with worn parts, lubrication becomes even more critical to protect these components.
Why does the synthetic more and requires less changes
The petroleum-based oil has a tendency to degrade under normal use of the engine. Over time it gets very hot and reaches a gaseous state, so it is useless for purposes of lubrication. Instead, the engine burning the residue is commonly known as carbon accumulation or burned. When the oil, some of it is washed adheres to engine parts, reducing yield. Frequently it needed oil changes to avoid this problem (every 3000-5000 miles; or 4828-8046 kilometers). The durability of the synthetic oil in the engine temperature it makes it a product of better performance because the synthetic still remains in liquid form, and usable. This temperature tolerance means that the oil can remain in the engine and can last as long as 7,000 miles (11,265 kilometers) before changing it.
Frequency of change
Most of the oils put guarantees a maximum length of mileage before a change 7,500 miles or 12,000 kilometers (many cars are closer to 5000 miles or 8,000 kilometers, even with better engines today). Because of the heat tolerance properties of synthetic oil 7,500 miles (12,000 km) are not a problem. That said, the frequency of oil change is a personal and financial decision.
You get a longer mileage with a synthetic oil, but you pay more per bottle because the price is usually more expensive. So you save money economically. Other reasons for the synthetic oil have nothing to do with the frequency, as some owners will partially synthetic oil put their cars.
Be careful when changing the oil types
If you are changing the oil frequently to extend the shelf life is not as simple as changing a new synthetic oil with an old mineral oil. You need to clean the system even after it is drained to confirm that no mixture is not formed. After washing, the first oil change should be around 2,000 to 3,000 miles (3218-4828 km) and other changes to get rid of waste from the final mixture.
