This Comp Cams break-in additive is formulated to be mixed with conventional break-in oil to provide the controlled friction and film properties needed for correct ring bite and cam activation without long-term residue. It supplies a temporary, high-friction profile that slowly disperses as the rings seat and the engine completes its break-in cycles.\u003c\/p\u003e\n\n\u003ch3\u003eHow do I use this product during first startup?\u003c\/h3\u003e\n\u003cp\u003eUse the entire 12 oz. bottle mixed into the recommended volume of conventional break-in oil for your engine — typically in the sump before the very first start. Follow Comp Cams or your engine builder’s break-in RPM and duration guidelines to ensure safe seating and reliable performance during the run-in period.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eAdd full 12 oz. to the specified quantity of break-in oil in the crankcase before initial startup.\u003c\/li\u003e\n  \u003cli\u003eStart and run the engine per manufacturer or builder instructions for controlled RPM and load.\u003c\/li\u003e\n  \u003cli\u003eChange the oil and filter after the prescribed break-in interval to remove contaminants.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat benefits does this additive provide for new rings and cam lobes?\u003c\/h3\u003e\n\u003cp\u003eThe additive creates a temporary friction and film balance that helps rings form a better seal against cylinder walls without excessively reducing contact required for seating. It also supports controlled cam and lifter break-in by minimizing abrasive particles and providing a conditioning film during the critical early hours.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003ePromotes improved piston ring seating for better compression and reduced blow-by.\u003c\/li\u003e\n  \u003cli\u003eHelps condition cam lobes and lifters by controlling early wear characteristics.\u003c\/li\u003e\n  \u003cli\u003eFormulated to blend with conventional break-in oils and be removed at the first oil change.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eIs this compatible with synthetic oils, additives, or performance parts?\u003c\/h3\u003e\n\u003cp\u003eComp Cams 159 is intended for use with conventional break-in oils rather than full synthetics; consult your engine builder for any exceptions. Avoid mixing multiple specialty additives unless specifically recommended, and always follow parts manufacturers’ guidance for lifters, cam profiles, and coatings.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eDesigned primarily for conventional break-in oil systems used during initial run-in.\u003c\/li\u003e\n  \u003cli\u003eCheck compatibility with coated camshafts, roller lifters, or nonstandard materials before use.\u003c\/li\u003e\n  \u003cli\u003eDo not rely on it as a permanent lubricant — perform the recommended oil and filter change after break-in.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eHow do I know when to change the oil after using this additive?\u003c\/h3\u003e\n\u003cp\u003eAfter completing the prescribed break-in routine (time and RPM\/load per your builder’s instructions), drain the oil and replace the filter. Changing the oil removes the break-in additive and captured debris, returning the engine to normal lubrication with the chosen long-term oil.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eComplete the full engine break-in schedule before performing the oil change.\u003c\/li\u003e\n  \u003cli\u003eDrain oil, replace filter, and refill with your selected long-term engine oil grade.\u003c\/li\u003e\n  \u003cli\u003eInspect for metal particles or abnormal residues and consult your builder if found.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eWho is this for: Builders and enthusiasts installing new or rebuilt gasoline engines who want a purpose-built, temporary break-in aid to support piston ring seating and cam conditioning.
