OE: 12605566 Oil Filter for Buick Excelle | Buick

Overview

Buick Excelle oil filter supports stable engine lubrication for GM compact sedan platforms.
For this reason, Buick specifies controlled filtration performance for this component.
The filter regulates oil flow while retaining contaminants generated during normal operation.
As a result, internal engine components receive cleaner and more consistent lubrication.

Vehicle Compatibility and Applications

Buick applies this oil filter across mainstream Excelle configurations.
Typical vehicles include Buick Excelle models produced from approximately 2015 onward.
Moreover, these vehicles commonly use naturally aspirated petrol engines.
The most frequent application appears on 1.5L engine variants used in mass-market trims.
In addition, the lubrication layout aligns with other GM small-displacement petrol platforms.

Material and Structural Design

The filter housing uses corrosion-resistant steel material.
Therefore, the exterior maintains strength under oil pressure and thermal cycling.
A precision-threaded metal base ensures secure installation.
At the same time, the sealing surface supports reliable contact with the engine block.
This construction supports consistent fitment during repeated service intervals.

Filtration Stability and Engine Protection

Stable oil circulation depends on controlled filtration.
For this reason, the filter supports consistent oil pressure during cold starts.
As a result, wear on bearings and valve train components remains controlled.
Moreover, reliable filtration helps protect timing and valvetrain systems.
This balance supports predictable engine performance in daily driving conditions.

OE Reference Integration

General Motors assigns OE number 12605566 to this oil filter.
This reference corresponds to ACDelco PF52E specifications.
It appears across multiple GM small-displacement petrol engine applications, including Buick Excelle.
However, engine-specific verification remains recommended before installation.

Maintenance and Replacement Guidance

Engine oil quality degrades with mileage and operating conditions.
Therefore, technicians replace the oil filter during every scheduled oil change.
GM service schedules typically align replacement with standard oil service intervals.
As a result, regular replacement supports long-term engine reliability.
Always follow official Buick maintenance documentation.

Installation and Fitment Notes

This oil filter installs directly onto factory mounting threads.
Moreover, original sealing surfaces remain unchanged during installation.
No modification to surrounding components is required.
Consequently, installation remains straightforward for professional technicians.
