Long-lasting synthetic oils. Conventional oils are not long-lasting, which generates waste oil. Frequently disposing of large quantities of oil is hazardous to human health and the environment due to its composition of lead, nickel, and other heavy metals. AMSOIL's long-lasting oil extends its lifespan to 11 times longer than conventional oils; pairing this oil with an oil analysis program can further extend its life span. AMSOIL achieves this by removing impurities and allowing molecules to slip more easily over one another, reducing energy lost to friction and maximizing fuel economy. These oils also have higher resistance to volatilization, reducing tailpipe emissions and consumption when exposed to high heat. This gives the oil high-temperature performance and efficiency. This oil also forms a more durable fluid film that reduces engine wear and is more fluid at colder temperatures.
