Q 1. What is BG Engine Purge for?

A. BG Engine Purge is an oil-system flush that safely removes accumulated sludge, soot and varnish deposits from the engine before an oil change. Restores compression on engines where sludge is impeding ring or oil-control function.

Q 2. How is BG Engine Purge used?

A. Drain old oil, refill with fresh oil to operating temperature. Add 946ml per 4 litres of new oil, run at 1,200–1,500 RPM for 15–20 minutes, drain, refit filter and add fresh oil plus BG MOA (115).

Q 3. Why does the procedure say to fit fresh oil twice?

A. The first fresh-oil fill is the carrier for BG Engine Purge — it dissolves the sludge then leaves the engine with the dirty oil. The second fresh-oil fill is the clean service oil the engine runs on afterwards.

Q 4. What is the warning about overheating during the procedure?

A. BG instructs that if the engine overheats or oil pressure drops at any point during or after the Purge run, shut the engine off immediately and do not drive the vehicle until the Purge is drained and new oil added.

Q 5. Is BG Engine Purge safe for petrol, diesel and rotary engines?

A. Yes. BG Engine Purge is safe for use in conventional, diesel and rotary engines. It contains no chlorinated solvents and is environmentally safe.

Q 6. What is the difference between BG Engine Purge and BG EPR (109)?

A. BG Engine Purge flushes sludge from the oil galleries — used as a pre-clean. BG EPR dissolves carbon deposits on piston rings to restore compression. Often run in sequence: Purge first, then EPR with the fresh oil.

Q 7. Can BG Engine Purge restore compression on its own?

A. BG states that Engine Purge can restore compression where sludge has built up around the rings and prevented them sealing. For carbon-deposit ring sticking, BG EPR is the appropriate follow-on product.

Q 8. How often should BG Engine Purge be used?

A. BG Engine Purge is typically used as a one-off restorative on neglected or high-mileage engines, not at every service. For preventive oil-system maintenance at every oil change, use BG MOA (115) or BG DOC (112) instead.

Q 9. When will my order be dispatched?

A. In-stock orders placed before 14:30 Monday to Friday are usually dispatched the same day.
