Since its introduction in 2005, technicians worldwide have used BG EPR as part of service routines to address engines showing low compression, noisy operation, or excessive oil consumption without immediate disassembly.\u003c\/p\u003e\n\n\u003ch3\u003eHow does BG EPR affect engine compression and drivability?\u003c\/h3\u003e\n\n\u003cp\u003eBG EPR acts during an oil change cycle to chemically soften and dissolve sludge and varnish that bind piston rings and obstruct oil passages. By freeing stuck rings and clearing restricted micro‑passageways, the product can allow rings to reseat and restore more even compression across cylinders, often improving power delivery and quieting noisy engines.\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003eSoftens deposits that prevent piston rings from sealing.\u003c\/li\u003e\n  \u003cli\u003eClears micro‑passages feeding hydraulic valve lifters and turbo actuators.\u003c\/li\u003e\n  \u003cli\u003eApplied during oil change—no engine teardown required.\u003c\/li\u003e\n  \u003cli\u003eProven in before\/after compression tests to raise cylinder pressures.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat is the correct way to use BG109 BG EPR during service?\u003c\/h3\u003e\n\n\u003cp\u003eBG EPR is used as part of a standard oil change: add the product to the engine oil, run the engine per instructions, then perform one or more oil and filter changes to remove dissolved deposits.

BG109 BG EPR is formulated for professional shops, technicians, and knowledgeable DIYers who want a chemical restoration option during an oil change to improve compression and restore smoother engine performance without immediate disassembly. It suits gasoline and compatible engines showing deposit buildup or compression loss; always follow vehicle manufacturer recommendations and product label instructions before use. The can is stamped with the latest production date and comes as an 11 oz (325 mL) unit, making it easy to store in a service bay or toolbox for targeted restoration jobs.\u003c\/p\u003e\n\n\u003ch3\u003eIngredients\u003c\/h3\u003e\n\u003cp\u003eBG109 Compression Engine Performance Restore BG EPR\u003c\/p\u003e\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Will BG EPR fix any engine with low compression?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: BG EPR can restore compression when deposits or stuck rings are the cause, but it cannot repair mechanical damage like scored cylinders or broken components.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: How many oil changes are needed with BG109?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Typically one treatment with a subsequent oil and filter change is recommended; a second change may be needed for heavy deposits per product instructions.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/section\u003e","brand":"BG","offers":[{"title":"Default Title","offer_id":48086979346590,"sku":"B00IAPLIDK","price":33.12,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0781\/2041\/9486\/files\/bg109-front-can-bg-epr.jpg?v=1785911881","url":"https:\/\/northtrailauto.ca\/products\/bg-engine-performance-restore-bg109-11-oz-oil-treatment-restores-compression-dissolves-piston-ring-deposits","provider":"North Trail Auto","version":"1.0","type":"link"}
