This supports reliable oil pressure and helps the engine operate smoothly under typical driving conditions.

• 5W cold rating enables faster oil circulation at startup.
• 30 high-temperature rating keeps viscosity stable under load.
• Synthetic base resists breakdown during long highway runs.
• OEM formulation aligns with Subaru factory tolerances.

• Bottle size: 5 quarts — suitable for most full oil changes.

Can I mix this OEM 5W-30 with other oils, and how often should I change it?

Mixing different oil brands or viscosities is generally safe in emergencies but not recommended for optimal performance; best practice is to use the same specification oil throughout the engine. Change intervals depend on driving conditions and manufacturer recommendations — consult your vehicle’s maintenance schedule.

• Avoid mixing different viscosities; stick to 5W-30 when specified.
• Mixing brands can dilute additive packages; consistent oil is preferred.
• Follow Subaru’s recommended oil-change intervals for your model/year.
• Severe driving (track, towing, dusty conditions) may require shorter intervals.
