Johnsen’s Premium Starting Fluid delivers fast, dependable ignition for hard-to-start gasoline and diesel engines. Its 50% ether blend fires quickly to shorten crank time and ease battery load, while an upper-cylinder lubricant helps protect rings, pistons, and valve seats during dry starts. Ideal for passenger vehicles, fleet trucks, tractors, construction equipment, and standby generators, it’s the go-to solution when engines have been sitting or conditions are demanding. Each can is 10.7 oz, and it is available in cases of 12 or cases of 48 to suit various operational needs.
