PG6311EX Extended Life Oil Filter up to 10,000 Miles - Pack of 6

Our review of the PG6311EX Extended Life Oil Filter finds it best suited for owners of compatible Toyota, Lexus, Pontiac and Scion models who want longer change intervals without sacrificing protection. The single biggest reason to buy is the filter media engineered to support up to 10,000 miles of service when used with synthetic oil, which reduces maintenance frequency while maintaining engine protection. Fit and material choices like a silicone anti-drain back valve and silicone gasket give confidence that the filter will perform in varied temperatures and repeated start-stop conditions.

Key Features

• Extended life media: Synthetic blend resin media is designed to deliver up to 10,000 miles of filter life with synthetic oil, helping owners extend service intervals.
• High efficiency filtration: The EX Series captures particles down to about 25 microns and claims 99% multi-pass efficiency, reducing contaminant circulation over the filter life.
• Start-up protection: A silicone anti-drain back valve helps prevent oil starvation on cold starts and stop-and-go driving by retaining oil in the filter.
• Temperature resilience: Silicone gasket and valve materials resist extreme heat and perform better in winter start-ups than more conventional components.
• OEM fit replacements: Marketed as a replacement for several OEM part numbers, it is intended to fit a range of 1.8L engines across Toyota, Lexus, Scion and Pontiac models when fitment is checked.

Who It's For

This oil filter is aimed at drivers who use synthetic oil or a synthetic blend and want the convenience of longer service intervals, especially owners of 2009-2018 Toyota Corolla, 2010-2018 Prius, 2011-2017 Lexus CT200h, 2009-2010 Pontiac Vibe and 2016 Scion iM models with compatible engines. It also suits DIY mechanics and small fleets seeking consistent fit and value across multiple vehicles since this listing is a pack of six.

Drivers using only conventional oil infrequently or those who follow shorter, manufacturer-mandated change intervals may prefer a standard lifespan filter. Always verify fitment with the vehicle filter tool before purchase to ensure correct application.
