Understanding PF66 Filter Compatibility
Although different brands use different part numbers, PF66 equivalents share the same critical specifications. This ensures that the replacement filter seals properly, maintains oil pressure, and protects engine components.
Most PF66-compatible filters are designed for:
- Gasoline engines
- Standard oil change intervals
- Passenger vehicles and light trucks
Always verify your vehicle’s year, engine size, and oil capacity before installing a replacement filter.Related Valvoline Oil Filter Cross Reference Chart(For All Brands)

Some drivers prefer premium brands due to filtration media, construction quality, or extended oil change intervals.
Cost Control
Aftermarket filters often provide the same fitment at a lower price, especially for routine maintenance.
Performance Options
Some equivalents offer high-efficiency synthetic media or extended-service designs for longer oil change intervals.

How to Choose the Right PF66 Replacement
1. Confirm engine compatibility
Even if the filter cross references correctly, always verify it matches your exact engine configuration.
2. Match your oil change interval
Choose standard filters for short intervals and extended-life filters for long-drain schedules.
3. Check filter dimensions if space is limited
Some vehicles have tight clearance around the oil filter mount.
4. Avoid mixing filter types
Always use a filter rated for the oil type and service interval you intend to run.

While applications vary by year and engine, PF66-style filters are commonly found on:
- Chevrolet sedans and SUVs
