Whats is the difference between synthetic oil and regular oil?

Synthetic is man made while the rest comes out of the ground. Synthetic is longer lasting and a better lubricant, although it's quite a bit more expensive. If you change your oil frequently the cheaper stuff is fine, but if you forget you are better off with Synthetic.Whats is the difference between synthetic oil and regular oil?

synthetic oil is man made unlike regular oil which is fossil based and refined. based on usage it is better to use synthetic specially on older cars. It is not carbon based hence it doesnt burn and turn black due to use. you can only use regular oil for like 3000 - 4000 miles between changes. unlike synthetic oils which are more viscous and bonds to your engine parts. They can be used as rated for 80,000 to 100,000 miles without changes on regular use. I have personally used Mobil 1 on my 1997 Nissan Sentra and am driving in tropical climates of the Philippines and have used it without change for 2 yrs or about 10,000 miles. I dont drive that far but traffic is gruelling and horendous in the Philippines. Depends on you driving habits and use these numbers can go lower or higher but definetly you will have fewer oil changes in a year. its a worthwhile investment.
