BG RF7 Engine Oil Treatment 11oz can — viscosity improver, ring conditioner for high‑mile engines

This 11oz can of BG RF-7 is formulated for professional use to increase oil viscosity and support better compression and oil pressure in worn or high-mileage engines. It combines viscosity-modifying polymers with corrosion inhibitors and seal conditioners to reduce internal leakage and slow oil oxidation without causing harmful thickening when used as directed.

How does BG RF7 help improve compression and reduce blow-by?

BG RF-7 thickens the lubrication film inside the engine just enough to help piston rings regain sealing performance, which can reduce the amount of combustion gases that pass the rings (blow-by). It does this through polymeric viscosity modifiers and ring-conditioning additives that temporarily improve ring-to-cylinder contact.

• Viscosity improvers increase oil film strength under compression.
• Seal conditioners soften and restore flexibility to aging seals.
• Ring-conditioning agents help achieve better ring seating.

Will using RF7 change my oil’s normal behavior or require special maintenance?

When used as directed, RF-7 is formulated to avoid permanent oil thickening or varnish buildup; it works with your current oil to provide short-term viscosity adjustment and protection. Routine oil and filter changes should continue on your regular schedule, and usage amounts follow BG recommendations for your oil capacity.

• Compatible with conventional and synthetic engine oils when used per instructions.
• Maintain regular oil change intervals; do not exceed recommended dosage.
• Follow BG application guidelines for engine size and condition.

What kinds of engine protection and anti-wear benefits does this product offer?

RF-7 contains corrosion inhibitors and anti-wear additives that form a protective layer on moving parts, helping limit metal-to-metal contact and reducing wear under load. It also resists oxidation to help keep oil performance stable under elevated temperatures and service intervals.

• Anti-wear components help protect bearings, rings, and valve train parts.
• Oxidation inhibitors help slow oil breakdown at high operating temperatures.
• Corrosion inhibitors guard critical components against acidic degradation.

How should I apply BG RF-7 and who should use it?

BG RF-7 is intended for professional or experienced users; add it to the crankcase at the recommended ratio based on engine oil capacity. Always follow the manufacturer’s instructions and safety precautions, and consult a technician if you are unsure about compatibility with your engine.

• Add to warm oil for best dispersion and mixing.
• Use the dosage that matches your engine’s oil volume and condition.
• Keep clear of ignition sources and observe safety warnings on the can.

Who is this for: BG RF7 #107 is aimed at professional technicians, automotive shops, and experienced DIYers who are restoring compression in aging engines, seeking short-term viscosity adjustment, or wanting extra anti-wear protection during service. It’s suited for engines showing mild blow-by, lower oil pressure, or where ring sealing improvement is desired. Note: this product contains chemicals known to the State of California to cause cancer and reproductive harm; handle per local safety rules.
