Items: Building and track equipment Fuel: 2-cycle glow fuel with 20%-25% nitromethane, 16% lubricant- 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.
