Depending on the type of synthetic, other advantages of synthetic lubricants (beyond the high- and low-temperature advantage) may include:
Improved energy efficiency (less than 1 percent) due to better low-temperature properties
Higher oil film strength with some synthetics
Extended warranties by some equipment manufacturers
Lower engine hydrocarbon emissions
Extended drain intervals in some (clean) applications
Biodegradability with some synthetics (esters)
Natural detergency
Higher viscosity index
Fire resistance (phosphate esters)
