AUTO JOHNSON STARTING FLUID – JSF

JOHNSON STARTING FLUID JSF is built to take the stress out of cold-weather starting. It’s a 50% ether blend that gives engines the quick spark they need when temperatures drop, while the upper cylinder lubricant adds a layer of protection during those dry, high-friction first seconds of ignition. From daily drivers to heavy-duty diesel equipment and small engines, JSF delivers dependable performance across a wide range of applications. It also complies with federal low-sulfur diesel standards, making it a safe choice for both on-road and non-road diesel use.
