The Subaru Exiga relies primarily on the FB20 naturally aspirated petrol boxer across most UK grey import variants, with EJ20 turbo and rare EE20 diesel options. While generally robust, oil consumption from piston ring wear, timing chain tensioner rattle and CVT compatibility concerns dominate replacement enquiries. Every rebuilt engine supplied through...
FB20 Oil Consumption
Most affected vehicles
Subaru Exiga 2.0i, Crossover 7, S Package (2008-2018, FB20/FB20A)
Failure mileage range
70,000-100,000 miles on grey imports with incomplete service history
Typical failure window
Root cause
Early FB20 piston ring design allows oil to bypass into combustion chamber; worsened by Japanese short-trip driving patterns and infrequent oil changes.
Repair options & estimated costs (UK ranges)
| Repair tier | Dealer price | Specialist price | What it involves | Longevity / suitability |
|---|---|---|---|---|
| Intermediate - PCV & Seal Refresh | £450 - £750 | £280 - £480 | Replace PCV valve, valve cover gaskets, monitor oil consumption | Temporary reduction; does not address root piston ring issue |
| Full Replacement - Rebuilt FB20 with Upgraded Rings | £3,200 - £4,800 | £2,200 - £3,800 | Supply & fit rebuilt FB20 with revised piston rings, bench tested, 12-month warranty | Permanent solution; addresses root cause with upgraded components |
Our recommendation
On a grey import Exiga worth £4,000-£8,000, if oil consumption exceeds 1L per 1,000 miles, replacement with a rebuilt FB20 featuring upgraded rings at £2,200-£3,800 offers better long-term value than repeated top-ups and risk of catalytic converter damage.
