The Importance and Difference of Engine Service with BG Fluids

Engine oil changes are the most common automotive maintenance service. However, a BG Oil Service offers much more: reliable engine performance and longer oil life, saving you money in repairs and at the pump. Keeping the inside of your engine clean and lubricated is critical for its proper function. But why is it so important to have a clean engine?

Why a Clean Engine Matters

Your engine’s horsepower and overall performance can drop when internal components get dirty. These dirty engines are inevitable, as residues including carbon deposits, fuel gums, varnish, and sludge build up inside the engine. Over time, these contaminants can severely impact engine performance and longevity.

Consequences of a Dirty Engine:

  • Reduced Horsepower: Deposits can obstruct airflow and fuel injection, causing a loss of power.
  • Decreased Fuel Efficiency: A dirty engine works harder, consuming more fuel.
  • Increased Wear and Tear: Residues cause abrasion and corrosion, leading to premature wear.

How a BG Oil Service Cleans and Protects Your Engine

The BG Oil Service is more than a standard oil change. It’s a deep-cleaning process that restores engine performance and protects against damaging carbon deposits.

Key Benefits of a BG Oil Service:

  • Cleans Stubborn Oil Deposits: BG EPR® Engine Performance Restoration® is added before each oil change to dissolve carbon deposits throughout your engine and on piston rings.
  • Stabilizes Oil Viscosity: Proper oil viscosity is maintained, ensuring optimal engine lubrication.
  • Improves Spark Plug Life: Cleaner engines reduce spark plug fouling.
  • Reduces Engine Wear: By removing harmful deposits, the engine components experience less friction and wear.
  • Prevents Sludge and Varnish: BG Advanced Formula MOA® is added to fresh oil to prevent sludge buildup and oil oxidation.
  • Prevents Excessive Oil Loss: Evaporative loss of oil is minimized, maintaining engine protection between oil changes.

BG EPR® Engine Performance Restoration®

BG EPR® is a powerful additive used before oil changes to dissolve carbon deposits and other residues. When the used oil is drained, the dissolved contaminants are removed, leaving the engine cleaner.

Benefits of BG EPR®:

  • Dissolves Hard Deposits: Targets tough-to-remove deposits that standard oil changes miss.
  • Restores Fuel Economy: Cleaner engines run more efficiently.
  • Maintains Hydraulic Functions: Keeps critical components such as valve train actuators and turbochargers functioning optimally.

BG Advanced Formula MOA®

After draining the old oil and adding fresh oil, BG Advanced Formula MOA® is included to maintain peak engine protection. This additive prevents the formation of sludge and varnish while stabilizing oil viscosity.

Benefits of BG Advanced Formula MOA®:

  • Keeps Piston Rings from Sticking: Ensures smooth engine operation.
  • Reduces Wear: Extends the life of engine components.
  • Prevents Increased Exhaust Emissions: Cleaner engines produce fewer emissions.

Upgrading to BG Engine Service Packages

Given today’s engine technology, with hotter combustion temperatures, higher cylinder pressures, and tighter tolerances, just an oil change is no longer sufficient for long-term engine efficiency. Main Street Mechanic has upgraded its oil changes to various Engine Service packages.

Package Options:

  1. Basic Engine Service Package: Includes BG Full Synthetic or BG Synthetic Blend Engine Oil and BG Advanced Formula MOA®.
  2. Advanced Engine Service Package: Adds BG EPR® to dissolve hard deposits and restore engine performance.
  3. Premium Engine Service Package: Incorporates BG Platinum® 44K® Fuel System Cleaner for thorough cleaning and optimal fuel economy.
  4. BG Engine Performance Service: A comprehensive package including all three additives plus a three-part deep cleaning of vital engine components.
