To clean a petrol or diesel fuel system, you may safely add Sea Foam to your fuel. Indeed, the more Sea Foam you add to the fuel, the more effective it is in cleaning!

Pour Sea Foam into the fuel tank to clean and lubricate the entire fuel system. It works by acting on injectors and carburettors by removing harmful residues and deposits caused by the passage of fuel through the intake valves, pistons and chamber areas.

Made with petroleum ingredients, Sea Foam is safe and effective to use with all types of petrol, diesel or blended fuels. Sea Foam does not contain any abrasive cleaners or chemicals that can damage engine or fuel system components.
