In the past, the conventional lubricant content used in fuel was 18%. But with new advanced technologies, fuels like Red Alert and O'Donnell for example, have a better quality of lubricants even though the percentages of lubricant content are lower. These high-tech lubricants provide exceptional cooling and protection.
