BG RF7 Engine Oil Treatment 11oz can — viscosity improver & seal conditioner for improved compression

BG RF7 #107 Engine Oil Treatment is a professional-grade 11oz additive formulated to increase oil viscosity, help improve compression, condition seals, and protect internal engine parts.

Designed for workshop use and advanced DIY maintenance, BG RF7 adjusts oil thickness to support tighter ring sealing and improved oil pressure without compromising additive balance. The formula contains stabilizers to resist oxidation and protect engine components from corrosive wear. Use as directed by BG; note this product carries a California Proposition 65 warning for potential exposure to chemicals known to the State of California to cause cancer or reproductive harm.

How does BG RF7 improve engine compression and performance?

BG RF7 increases the effective viscosity of engine oil, which helps form a firmer lubricant film and encourages piston rings to seal more tightly. Better sealing reduces blow-by and can translate to steadier compression readings and improved throttle response in engines with worn rings. Results depend on engine condition, operating temperatures, and the type of base oil being treated.

• Viscosity improver boosts oil film thickness under operating loads
• Ring-sealing agents help reduce combustion gas blow-by
• Improved oil pressure supports consistent lubrication

Will BG RF7 protect internal parts and resist oil degradation?

The formula includes anti-oxidants and corrosion inhibitors to slow oil thickening from oxidation and to protect metal surfaces from corrosive attack. It also contains wear-reducing additives that support moving parts during start-up and steady-state operation. Regularly monitoring oil condition remains important when using any additive.

• Anti-oxidant components reduce sludge and varnish formation
• Corrosion inhibitors shield bearings and journals
• Wear modifiers enhance film strength at contact points

How should I use this 11oz can of BG RF7 in my vehicle?

BG RF7 is intended as a concentrated treatment added to the crankcase oil per BG’s instructions or a professional technician’s recommendation. Use the specified dose relative to oil capacity—too much product can excessively alter oil properties. After adding, run the engine to ensure thorough mixing and verify performance changes with appropriate diagnostics.

• Follow BG dosing guidelines for engine oil capacity
• Mix by running engine briefly after addition
• Check oil pressure and compression readings before/after use

Are there safety or regulatory considerations I need to know?

Handle BG RF7 with standard shop safety precautions: work in a ventilated area, avoid skin contact, and store away from flames. Dispose of contaminated rags and used oil in accordance with local hazardous-waste rules. This product carries a California Proposition 65 notice; consult the Safety Data Sheet for full hazard and handling details.

• Use gloves and eye protection during handling
• Keep away from open flames and high heat sources
• Refer to BG SDS for detailed hazard information

Who is this for: BG RF7 #107 is aimed at professional technicians, performance shops, and experienced DIYers who need a targeted viscosity improver and ring-conditioning treatment for engines showing reduced compression or low oil pressure. It’s best used where controlled, measured additive application and follow-up diagnostics are practical; it’s not a substitute for mechanical repair when severe wear or damage is present.
