BG RF7 Engine Oil Treatment - 11oz Can, Viscosity Improver & Seal Conditioner

BG RF7 #107 Engine Oil Treatment is a professional-grade 11oz oil viscosity improver and seal-conditioning formula designed to raise oil viscosity, help restore compression and protect internal engine surfaces.

BG RF7 is formulated for mechanics and DIYers who need a targeted oil treatment to modify oil flow characteristics, condition seals, reduce blow-by and protect moving parts from wear and corrosion. The concentrated 11oz can is intended for use as an additive to existing engine oils where a viscosity boost and improved sealing are desired without changing the base oil.

How does BG RF7 improve engine compression?

BG RF7 thickens the oil film slightly to help reduce ring blow-by and restore more effective sealing between pistons and cylinder walls. It also contains ingredients that help condition piston rings and seals so compression losses from minor wear can be reduced.

• Viscosity improvers that increase oil film thickness under operating temperatures
• Seal conditioners that help swell and soften rubber components for better sealing
• Formulation intended to reduce blow-by and recover lost compression where wear is moderate

Will this product protect engine parts and reduce wear?

Yes—BG RF7 adds protective additives that help limit oxidation and corrosive damage while improving lubrication under stress. These ingredients supplement the vehicle's oil to provide extra protection for bearings, rings and other moving parts.

• Anti-oxidants to slow oil degradation and extend oil effectiveness
• Wear inhibitors that form a protective layer on metal surfaces
• Corrosion inhibitors that help protect internal components from acidic byproducts

Is BG RF7 safe and how should it be used?

Use BG RF7 as an engine oil additive following manufacturer recommendations for dosage and service intervals. It is formulated for professional and consumer use, but users should follow safety precautions and dispose of waste fluids properly.

• Add the 11oz can to the engine oil per label directions or technician guidance
• Observe standard handling precautions: avoid skin contact and ventilate during application
• Follow local regulations for disposal of used oil and any leftover product

How quickly will I notice differences after adding RF7?

Some drivers report measurable improvement in oil pressure and engine smoothness after one fill; results vary with engine condition and severity of wear. Best results occur in engines with moderate oil thinning or minor sealing issues rather than severe mechanical damage.

• Potential oil pressure gain visible on first drive cycle
• Smoother idle and reduced blow-by may develop over several heat cycles
• Not a substitute for mechanical repairs when major wear or damage exists

Who is this for: BG RF7 #107 is aimed at professional technicians and informed vehicle owners who want a concentrated, professional-use oil treatment to boost viscosity, condition seals and add protective additives. It is suitable for engines showing mild-to-moderate oil thinning, reduced compression or where extra protection against wear and oxidation is desired. Always consult your vehicle’s service recommendations before using oil additives, and follow all safety and environmental handling guidelines. Note: this product can expose you to chemicals known to the State of California to cause cancer and reproductive harm; handle with care and refer to the product Safety Data Sheet for full precautions.
