BG MOA Advanced Formula Engine Oil Conditioner is designed to enhance engine oil and extend engine oil life. The unique blend of additives in the product maintains engine cleanliness and performance under high load conditions.
Modern operating conditions of a car in the urban cycle (warm-ups, start-stop, short trips, extended intervals between oil changes) and high operating temperatures lead to a rapid depletion of the required additive package in the engine oil. This leads to the accumulation of more unburned fuel and other combustion products in the engine oil, which leads to the rapid oxidation of engine oils. Oxidation causes oil to thicken and deposits in the crankcase, oil filter, oil passages and other critical internal engine surfaces.
BG Advanced Formula MOA® Engine Oil Conditioner is designed to maximize the performance of synthetic and mineral engine oils and extend engine oil life.
The product prevents oxidation and an increase in the viscosity of the engine oil even under high load conditions.
Keeps compression rings, lifters, tensioners and other engine components clean for long engine life and lowers maintenance costs.
Excellent for gasoline engine use.
Compatible with synthetic and mineral motor oils.
Benefits:
increases the strength of the oil film
prevents oxidation and oil thickening
prevents the formation of sludge and varnish deposits when driving in the urban cycle
protects against rust and corrosion
provides increased power and performance
reduces harmful emissions into the atmosphere
Excellent long-term protection of engine parts against wear!
Used by:
Restoring the elasticity of the elements of the oil system of a gasoline engine

HOW IS A BMC FILTER REGENERATED?
We recommend using original BMC kits only, as other products may not be effective or may damage the filter permanently, thus invalidating the warranty.
We recommend regenerating the filter (washing + oil application) every 20.000 – 25.000 km to ensure best performance and long service life.
This value is a rough estimate and can vary based on the climatic conditions and the ground on which the vehicle is used (sand, dirt roads, etc.).
The various steps to be carried out in order to regenerate the filtering element are indicated in the instructions contained in the regeneration kit.

BMC air filters are designed and produced to ensure a higher air flow than original paper filters. In F1, for example, BMC cotton filters minimize the loss of air flow pressure passing through the air filter; this way ensures the best conditions for full exploitation of maximum power. Therefore the benefits of replacing the original paper filter with BMC cotton air filter, produced using the same technology and materials as the F1 air filters, are evident.
DESIGN AND MATERIALS
Qualified engineers using advanced software and expert technicians using the latest technologies produce BMC air filters. An F1 filter must be very light, must be made of the best raw materials and must improve performance. For this reason we use only alloy mesh with epoxy coating to ensure protection from petrol fumes and from oxidization due to the humidity of the air. The filtering material is composed of a special cotton gauze soaked with low-viscosity oil to give you the best air permeability.

Why Are Porsche Service Parts Important?
Porsches are high-performance sports cars, engineered
to precise tolerances. Every component plays a role in ensuring your car
delivers the driving experience it’s known for. Over time, even the
best-engineered parts wear down through:
- Heat
and friction (spark plugs, ignition coils, belts)
- Fluid
degradation (engine oil, coolant, lubricants)
- Environmental exposure (filters, wipers, seals)
Replacing worn parts with high-quality service items helps
maintain:
- Peak
Performance – keeping your Porsche responsive and reliable
- Safety
– ensuring brakes, steering, and ignition components function properly
- Longevity – protecting the engine, gearbox, and major systems from unnecessary wear
How to Know Which Service Parts You Need
The best way to determine what your Porsche requires is to book a service with a Porsche specialist garage. Trained technicians can diagnose issues and advise on necessary replacements with accuracy. A Porsche is not just another car - it’s a finely tuned performance machine that demands the expertise of specialists to maintain properly.
During routine servicing, additional work is often identified, especially on Porsches over 15 years old. Their build quality means they last for decades, but when TLC is needed, addressing issues early is essential to avoid more serious (and costly) problems down the road.

Service Part Fitment, System Compatibility and Quality
Correct fitment and system compatibility are essential to maintain Porsche reliability, efficiency, and long-term durability. Every component supplied by Design911 is engineered to meet original Porsche specifications, ensuring accurate installation and dependable operation across all service systems.
Matched to Original Porsche Service Standards
Routine service components must operate within strict tolerances to maintain engine protection and performance. Genuine and OEM-approved parts ensure proper filtration, ignition performance, lubrication flow, and cooling system operation across both classic and modern Porsche models.
Designed for Complete Service System Integration
Modern Porsche servicing relies on multiple interconnected systems working together efficiently. Engine protection is maintained through correctly specified engine oils and lubricants, supported by high-quality filtration and ignition components. Cooling performance is maintained with coolant and antifreeze, while visibility and safety are supported through correctly fitting front wiper blades and rear wiper components.
Supporting Lubrication, Cooling and Gearbox Maintenance
Long-term reliability also depends on servicing drivetrain and auxiliary systems correctly. Components such as gearbox service parts, power steering oil, and specialist lubricants help maintain smooth operation, reduce wear, and protect critical components under varying driving conditions.
Reducing Wear and Long-Term Mechanical Stress
Using incorrectly specified service parts can lead to premature wear, contamination, reduced efficiency, or system failure. Design911 helps minimise these risks with factory-correct service components, lubricants, and maintenance products designed specifically for Porsche vehicles.
Porsche Service Part Maintenance and Longevity
Routine servicing is essential to maintain Porsche performance, reliability, and efficiency over time.
