Suitable for regular/synthetic motor oils Contains no solids to clog filters or inhibit flow. Will not harm oxygen sensors or catalytic convertors. Usage Directions Simply add entire contents to 3-5 litres of engine oil (10% treat rate), and leave the engine to run for 15 minutes. At the normal oil change interval drain as usual.
