About STP Oil Filters
STP started in the 1950s. The brand is popular for oil additives, car cleaners, and filters. STP oil filters are available worldwide. Drivers like STP because the brand is easy to find and affordable.
Types of STP Oil Filters
1. Standard Oil Filters
These filters work for daily city and highway driving. They protect the engine from normal dirt and particles.
2. Premium Oil Filters
Premium filters have stronger filter paper. They can trap smaller particles. These filters last longer and protect the engine better during heavy use.
3. High-Performance Oil Filters
High-performance filters are for sports cars, trucks, or cars that carry heavy loads. They filter faster and hold more dirt before clogging.
How STP Oil Filters Work?
Filtration Technology
STP uses paper or synthetic filter media inside the filter. Oil passes through this media. Dirt, dust, and metal particles stay in the filter. Clean oil goes back to the engine.
Anti-Drainback Valve
Many STP filters have a small valve called an anti-drainback valve. It stops oil from draining out when the engine is off. This keeps the engine ready to run at startup.
Strong Filter Case
The metal case of the filter is strong. It can handle high pressure inside the engine. This prevents leaks and filter damage.
Performance of STP Oil Filters

Dirt Holding Capacity
STP filters hold a good amount of dirt before they need replacement. Standard filters may hold less dirt than premium filters. This is why frequent oil changes are important.
Flow Rate
Flow rate means how fast oil can pass through the filter. STP filters allow enough oil to reach the engine quickly. This keeps the engine lubricated and prevents overheating.
Engine Protection
Clean oil prevents engine wear. STP filters remove harmful particles. This helps the engine last longer and run smoothly.
