Magellan International Oil System Cleaner is designed to remove the damaging and lifespan reducing deposits that typically remain in engine even after oil and filter changes. Intended for use prior to an oil change, Magellan International Oil System Cleaner loosens varnish, carbon, sludge and other contaminants, dissolving them in the old oil so that they are easily removed upon draining. This allows the new oil to perform to its full potential — rather than start off instantly contaminated.
Add directly to existing engine oil prior to oil change. Run engine for 15 minutes, drain oil and replace.
