Most of the fuels we carry meet or exceed the lubricant content
required for optimum performance and maximum engine life. 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.
