Keep your Subie Healthy with our 30/90k Service Package

Subaru 30k / 90k Service

This service includes:

Intake Valve Cleaning (BG) (Direct Injection Only)

Direct injection engines don’t wash intake valves with fuel, causing carbon buildup. PCV function helps reduce buildup, but periodic cleaning is still required.

Applies to:

2014+ Forester XT, 2019+ Forester, 2017+ Impreza, 2018+ Crosstrek, 2020+ Outback

(30k interval)

Front & Rear Differential Service

GL-5 75W-90 synthetic limited-slip fluid

(30k interval)

CVT Transmission Service

BG CVT fluid + conditioner, TCM relearn + adaptation reset

(30k interval)

Subaru recommends ~25k (severe) to 36k intervals. We follow a 30k interval for reliability.

Subaru of Japan and many other Subaru corporations say this is a 3 year or 36 interval for regular service. Even in America, they recommend changing it every 25k for severe service which would include mountain driving so we stick with 30k recommendations

*No fluid is lifetime fluid! This was a very harmful recommendation from Subaru of America that directly contradicted Subaru of Japan at the time.

Note:

Why TCM Relearn Matters (After CVT Service)

The transmission control module (TCM) adapts over time to fluid condition, pressure, and wear. Fresh fluid changes those characteristics.

Without a relearn, this can cause:

Harsh or delayed engagement

Shuddering or RPM flare

Excessive line pressure and added wear

While the system can relearn over time, performing a TCM relearn immediately ensures proper line pressure and shift behavior, reducing unnecessary stress and improving drivability.
