Scientists are adding microscopic particles of graphene—sheets of carbon just one atom thick—to regular motor oils to create super-slippery nano-lubricants. These tiny graphene flakes act like molecular ball bearings, rolling between metal surfaces and reducing friction by up to 30% more than conventional oils alone. In tests, engines using graphene-enhanced oils showed significantly less wear on pistons and cylinders, potentially extending engine life by years. Researchers discovered that graphene naturally forms a protective film on metal surfaces that's stronger than steel but smoother than ice.
