Q&A

• How does using synthetic oil with a 5W-40 rating provide better engine protection compared to conventional oil?

  Using synthetic oil for a 5W-40 rating retains viscosity properties for a longer duration, providing better engine protection compared to conventional oil. Synthetic base oil is crucial for achieving a lower viscosity rating, and the viscosity difference between used and new synthetic oil is minimal, while the difference is significant with conventional oil, ensuring better engine protection towards the end of the oil drain interval.

• Do both synthetic and conventional motor oils require regular replacement, and why?

  Both synthetic and conventional motor oils have different viscosity characteristics but require regular replacement due to the wear of additives over time. Although synthetic oils provide better protection toward the end of the oil change interval due to viscosity differences, car manufacturers' recommended oil change intervals should always be followed to maintain the optimal performance of the engine.

• How does synthetic motor oil provide better protection at the end of the oil change interval compared to conventional oil?

  Synthetic motor oil provides better protection at the end of the oil change interval compared to conventional oil due to its reduced breakdown and better viscosity performance. The resistance to breakdown and viscosity changes over time is superior in synthetic oil, ensuring better engine protection at the end of the oil change interval.

• What are the additives used in motor oil, and how do they affect viscosity?

  Additives like pour point depressants lower viscosity at low temperatures, while viscosity index improvers increase viscosity at high temperatures. Synthetic motor oils have a multi-grade characteristic from the base oil formulation, reducing the need for additional viscosity-modifying additives. Additives like pour point depressants and viscosity index improvers are used to modify oil viscosity at different temperatures, but synthetic motor oils already have a multi-grade characteristic, reducing the need for additional viscosity-modifying additives.

• How is motor oil viscosity graded, and what are multi-grade oils?

  Motor oils are graded based on viscosity, and multi-grade oils have properties of both thinner and thicker viscosity oils. They provide good startup performance and engine protection at operating temperature. Viscosity is graded based on temperature, and multi-grade oils have characteristics of both thinner and thicker viscosity oils, providing good startup performance and engine protection at operating temperature. Additives are used to create multi-grade conventional motor oil.

• What are the benefits of synthetic motor oil over conventional motor oil?

  Synthetic motor oil offers benefits over conventional motor oil due to differences in viscosity. Viscosity refers to the oil's resistance to flow, with higher viscosity indicating thicker oil and lower viscosity indicating thinner oil. The rating system for motor oils includes a cold rating (e.g. 5W) and an operating temperature rating (e.g. SAE 30). Synthetic motor oils, such as Pennzoil Platinum derived from natural gas, demonstrate superior performance in terms of viscosity and temperature ratings.
