Synthetic or Base petroleum Lubricants which works Better for you

The technical advantages of synthetic motor oils include:

• Measurably better low and high temperature viscosity performance^{[citation needed]}
• Better chemical & shear stability
• Decreased evaporative loss^{[citation needed]}
• Resistance to oxidation, thermal breakdown and oil sludge problems
• Extended drain intervals with the environmental benefit of less oil waste.^{[citation needed]}
• Improved fuel economy in certain engine configurations.^{[citation needed]}

The disadvantages of synthetic motor oils include:

• Initial costs are usually four times greater than petroleum-based oils, though at one time, man-made oils cost ten times more than petroleum^{[citation needed]}. Initial costs are often mitigated by extended change intervals, which individuals may confirm through used oil analysis (UOA).
