What is the advantages and pitfalls between synthetic oil and mineral oil?

Some said that synthetic oil can last more longer.


Lets say... it can sustain up to 10,000KM meanwhile mineral oil needed to change at every interval of 5000KM.





How true it is?





Have you heard about semi-synthetic oil? How do we know whether the oil that we purchasing was semi-synthetic oil?


Are the manufacturers goin to label there?





And what the hell they created semi-synthetic oil?


If they wanted to create a man, just create it and not something in-between. That was totally ridiculous.What is the advantages and pitfalls between synthetic oil and mineral oil?
Before synblend, I often used both Mobil One http://www.mobiloil.com and standard petroleum mixed together because they always have been compatible. Mostly I used full synthetic Mobil One since the 60's on all my cars and I've never had any major engine work in over 200,000 miles on all the cars. However, full synthetics are now $5 a quart even at price clubs, so a synblend will give you much of the same performance at a lesser cost. Ford now does all it's oil changes using Motorcraft synblend. Since I have many Fords, I go to the dealer and get the synlube and a Motorcraft oil filter for about $23. Not a bad deal considering your getting dealer quality parts and service. I believe Ford allows 7500 mile extended service oil changes using it's Motorcraft synblend oil.What is the advantages and pitfalls between synthetic oil and mineral oil?
Overall, synthetic oil is better than normal engine oil. The only negatives are the price and if you have an oil leak, usually synthetic will leak out faster because it flows better. Synthetic oil won't break down as fast as regular oil and you can go a little longer between changes. I usually run 1 quart of synthetic with my regular oil. I get some of the benefit without spending the extra money.
