New formulation of the original Friction Proofing launched 70 years ago.

• New fully synthetic formula is compatible with synthetic, semi-synthetic and mineral oil-based engine oils.
• Specially formulated to reduce friction and wear, improve oxidation and stability, increase engine cleanliness and improve fuel economy.
• Features cutting edge technology to improve engine oil performance without exceeding the American Petroleum Institute (API) SM limits on sulfur and phosphorus.

Formulated with premium PI SJ/ILSAC GF-2 additive technology.

• Cleans varnish and sludge deposits from the engine.
• Reduces oil oxidation between regular oil change services.
• Neutralizes harmful acids caused by combustion blow-by.
• Prevents rust caused by harmful acids.
• U.S. Patent No. 4,557,841 Each kit contains: #61610 OilSystem Cleaner & Conditioner and #64328B Supreme +Plus+ Oil Treatment.

Products also sold separately.

Add contents to engine oil.

• Prolong engine life by reducing friction and engine wear.
• Inhibit oil oxidation.
• Protect against rust and corrosion.

• Guard against contamination of new oil by more completely removing the old oil normally left in the crankcase during a conventional oil change process.
• Safely dissolve and remove sludge and varnish.
• Improve compression and reduce oil consumption.
• Reduce contamination of new oil so that oil stays cleaner, longer.
• Prolong the life of new oil and decrease oil oxidation.
• Protects the engine from excessive wear during and following the service.
• Reduces deposits build up that can block oil lines and screens and restrict proper engine lubrication.
• Five micron filters safely remove particulates and debris that the standard oil filter leaves behind.

U.S. Patent No. 4,557,841

• Removes up to 20% (3/4 quart) additional used oil versus conventional oil change so that oil stays cleaner, longer.
