2015 Subaru Crosstrek Excessive Oil Consumption (FB20): What It Really Costs to Fix
Quick answer: 2015 Subaru Crosstrek excessive oil consumption (fb20) typically costs $50 to $4,500 at an independent shop, depending on which component failed.
Applies to: 2013, or 2014-2015 manual only. Other versions of the 2015 Subaru Crosstrek do not have this problem.
What the Issue Is
The GP Crosstrek (badged XV Crosstrek in these years) runs the FB20 2.0-liter boxer, and the FB family's oil-consumption problem came with it: oil getting past the piston rings into the combustion chambers, regular top-ups between changes, and a low-oil warning that becomes a familiar sight. The Yaeger v. Subaru class action, settled with final approval on August 31, 2016, gave covered cars 8 years/100,000 miles of coverage for consumption repairs, with a replacement short block as the definitive fix. For the Crosstrek it covered 2013 cars with the CVT (within VIN ranges) and 2013 to 2015 cars with the manual, so a 2015 Crosstrek was inside it only with the manual transmission.
Post-settlement economics follow the family script: the coverage has aged out, short blocks cost engine money, and managing consumption with top-ups is the cheaper path on an engine that otherwise serves typical Subaru spans. The Crosstrek's used-market position sharpens the stakes: entry-level pricing draws first-car and budget buyers who may not run monthly dipstick checks, which is exactly the ownership style consumption punishes.
Diligence runs the FB protocol: paperwork first, because a settlement-era short-block invoice turns a specific car into a documented non-issue; then the dipstick-against-claimed-service check, the top-off candor interview, and the cold-start smoke watch. Note the gearbox on 2014 and 2015 cars, since only manuals were in the settlement. A stable-level FB20 with records is simply a small Subaru with the model's usual virtues; a thirsty one is a manageable but priceable top-off lifestyle.
Symptoms to Watch For
- 1.Low-oil warnings between scheduled changes
- 2.Quart-scale top-offs between oil changes
- 3.Blue startup smoke after sitting (progressed cases)
- 4.Plug fouling at intervals
- 5.Top-off bottles in the cargo area and candor in the interview
Real Repair Costs
Managed top-offs are the cheap path; short-block replacement is the definitive fix at engine prices. The settlement coverage has expired, and a 2014 or 2015 Crosstrek with the CVT was never part of it.
| Repair | Typical Cost (installed) |
|---|---|
| Managed consumption (top-offs)per year | $50-$150 |
| Oil consumption test (measured verdict) | $50-$150 |
| Short block replacement, installedthe definitive fix | $3,000-$4,500 |
Moderate issue. Ranges are US independent-shop estimates with quality parts. Use them as negotiation grounding, not a quote.
Mechanic's Tip: Spot It Before You Buy
Run the FB interview in order: records first, because a settlement-era short-block invoice settles the question outright; then pull the dipstick against the claimed last-change date and mileage, since a full change 2,000 miles ago reading low is the defect announcing itself. Ask the direct question casually: how much oil does it use between changes? Finish with a cold-start watch for blue smoke after the car has sat through your paperwork review. Stable level plus records buys the model's virtues; a thirsty example is negotiable, not disqualifying, so price the vigilance lifestyle and the short-block ceiling.
The Bigger Ownership Picture
Beyond this specific issue, budget roughly $900-$1,400 per year for scheduled maintenance and repairs on a 2015 Subaru Crosstrek. That is a typical US range from Avturo's ownership-cost table, an estimate rather than a quote, and it excludes insurance, fuel, and financing.

Frequently Asked Questions
Does the Subaru Crosstrek burn oil?▼
Early GP cars share the FB engine family's documented ring-pack problem. The Yaeger v. Subaru settlement covered 2013 Crosstreks with the CVT (within VIN ranges) and 2013 to 2015 Crosstreks with the manual; a 2014 or 2015 CVT car was outside it. Not every engine consumes, which is why per-car verification beats model-level fear.
What does the oil consumption fix cost?▼
The definitive fix, a replacement short block, runs about $3,000 to $4,500 installed at independents now that settlement coverage has expired. The alternative is managed consumption: $50 to $150 a year in top-offs plus a checking habit. The short block is engine-scale money that only pencils out on an otherwise excellent car.
Is oil consumption dangerous for the engine?▼
Consumption managed is a nuisance; consumption ignored is how these engines die, because run low, a boxer wears its bearings and cooks itself like anything else. The real risk is behavioral: owners who check monthly and top off promptly keep the engine safe, which makes the dipstick habit the entire difference between annoyance and catastrophe.
How do I know if a used Crosstrek had the short block replaced?▼
Invoices name it explicitly (short block assembly, gaskets, and labor at engine-job scale), and a Subaru dealer can often confirm warranty engine work by VIN. That paperwork converts the model's defining risk into a documented non-issue on the specific car and is worth paying a premium over an undocumented equivalent.
