Restore Ring Function by Removing Hard-to-Reach Engine Deposits.
BG EPR® Engine Performance Restoration® is a professional crankcase cleaning treatment formulated to soften, emulsify and dissolve stubborn fuel gums and engine-oil deposits that can restrict piston-ring movement.
Restricted piston rings may not seal the combustion chamber effectively, contributing to oil consumption, blow-by, reduced compression and power loss.
BG states that EPR also cleans micro passageways supporting hydraulic functions in valve-train actuators and turbochargers. It suspends loosened contamination in the old oil so it can be drained during the oil change.
Four Core Benefits of BG EPR®
EPR targets deposit-related ring restriction and oil-flow contamination that can affect compression, oil control and hydraulic engine functions.
Helps Eliminate Oil Consumption Issues
By removing deposits and restoring piston-ring movement, EPR can help reduce oil consumption that is related to stuck or restricted rings.
Removes Fuel Gums & Engine-Oil Deposits
Softens, emulsifies and dissolves hard-to-remove fuel gums and oil deposits that can clog piston rings and interfere with normal ring function.
Dramatically Improves Compression
Cleaner, freer-moving piston rings can seal the combustion chamber more effectively, helping restore compression and reduce blow-by.
Cleans Critical Micro Passageways
Helps maintain vital hydraulic functions in components such as valve-train actuators and turbochargers by cleaning restrictive internal passageways.
What BG EPR® Is Designed to Restore
BG positions EPR as an engine-restoration treatment for ring cleanliness and compression.
Restricted Piston Rings Can Affect More Than Oil Consumption.
Ring deposits can affect compression, crankcase contamination and overall engine efficiency.
Compression Loss
Deposits can prevent piston rings from expanding and sealing properly against the cylinder wall, allowing compression to escape.
Oil Consumption
Restricted oil-control rings can allow engine oil to move into the combustion chamber and burn instead of returning properly to the crankcase.
Blow-By & Oil Dilution
Poor ring sealing can allow fuel and combustion gases to enter the crankcase, contaminating engine oil and reducing lubrication quality.
Restricted Hydraulic Functions
Deposits in small oil passageways can interfere with the hydraulic operation of components such as valve-train actuators and turbochargers.
BG EPR® Is Used Before the Oil Is Drained.
Unlike a leave-in oil fortifier, EPR performs its cleaning work in the old engine oil and is removed during the same service.
Confirm Engine Condition & Capacity
We verify crankcase capacity and make sure the engine is an appropriate candidate for EPR. BG specifically warns against use in engines with excessive sludge.
Add the Correct Amount of EPR
For a typical 4–6 quart crankcase, BG specifies one 11 fl. oz. can. Dosage changes with crankcase capacity.
Circulate at Operating Temperature
For 4–6 quart engines, BG directs the engine to run at 1,200 RPM for 10 minutes; GDI engines and small light-duty passenger diesels require at least 20 minutes.
Drain, Replace Filter & Refill
The old oil and suspended contamination are drained, the oil filter is replaced and the crankcase is refilled with the correct fresh engine oil.
When an EPR® Service May Be Worth Discussing With Our Team.
Oil Consumption
If deposit-restricted oil-control rings are contributing to oil consumption, EPR may help restore ring function and reduce oil use.
Reduced Compression or Power
Deposit-related ring sealing problems can reduce compression and engine output. EPR is designed to restore ring movement and sealing.
Fuel Smell in Engine Oil
Blow-by can allow fuel contamination into the crankcase. Restoring ring sealing can help reduce oil dilution when deposits are part of the cause.
Preventive Engine Performance Service
BG recommends EPR as part of professional engine performance maintenance and lists it for gasoline, hybrid and diesel service procedures.
EPR Cleans Before the Oil Change — It Does Not Replace One.
BG EPR is a pre-oil-change cleaning treatment. Its purpose is to dissolve and suspend deposits in the old engine oil so those contaminants leave the engine when the oil is drained.
A leave-in oil fortifier such as BG Advanced Formula MOA® serves a different role after the cleaning step.
EPR® Can Be Part of a Qualifying BG Engine Plus Service.
BG currently lists PN 109 together with BG Advanced Formula MOA® PN 115 in its qualifying Engine Plus Service for gasoline and hybrid vehicles, and with BG DOC® PN 112 for qualifying diesel applications.
The current plan lists a 10,000-mile service interval for the Engine Plus Service with maximum coverage of $6,000 under Plan 1 and $3,000 under Plan 2. Coverage applies only when the complete qualifying BG service is performed according to current program requirements.
EPR by itself does not automatically create Lifetime BG Protection Plan® coverage. Vehicle eligibility, first-service mileage, service history, approved procedures and required repeat intervals all matter. BG also states that oil-consumption claims themselves are not covered under engine coverage.
Engine Cleaning With Professional Evaluation.
Oil consumption and compression concerns can come from deposits, wear or leaks. EPR is most useful when deposit restriction is involved.
Our team can evaluate the vehicle, confirm capacity and perform the correct EPR procedure with the required oil and filter service.
Common Questions About BG EPR®
BG EPR® is a crankcase cleaner designed to soften, emulsify and dissolve fuel gums, carbon and engine-oil deposits that can restrict piston rings and small oil passageways.
BG states that EPR can reduce oil consumption by restoring piston-ring function when deposits are preventing the rings from moving and sealing properly. Oil consumption caused by mechanical wear or leaks still requires diagnosis.
By removing deposits that restrict piston rings, EPR helps the rings seal the combustion chamber more effectively. BG states that this can restore compression and reduce blow-by.
BG describes small engine-oil passageways that support hydraulic components such as valve-train actuators and turbochargers. EPR is formulated to clean these restrictive oil pathways.
No. EPR is circulated in the old engine oil for the specified cleaning period, then the oil is drained and the oil filter is replaced. BG specifically advises against leaving EPR in the engine until the next oil change.
For a typical 4–6 quart engine, BG specifies 10 minutes at 1,200 RPM, or at least 20 minutes for GDI and small light-duty passenger diesel engines.
BG includes EPR in published gasoline, hybrid and light-duty diesel service procedures.
No. BG lists PN 109 as part of qualifying Engine Plus and Engine Performance service combinations, but eligibility depends on the complete approved service, vehicle eligibility and current BG Protection Plan requirements.
