Tal vez estoy hilando muy delgado con el tema que voy a mencionar pero creo que es pertinente. Con todo este alboroto de la trampa de VW y sus motores diesel, de repente Subaru of America (SOA) ha emitido un TSB (Technical Service Bulletin) en el que cambia de posición respecto del arreglo que se debe hacer en los motores que han presentado un alto consumo de aceite.
Digo "de repente y cambio de posición" porque el problema de consumo de aceite ha sido evidente y de larga data, y las quejas de los propietarios de los vehículos afectados no eran atendidas de manera que los dejara satisfechos. El arreglo a que eran sometidos los vehículos se limitaba a cambiar los anillos de control de aceite en los pistones y sin embargo el problema persistía. Me late que para evitar problemas como el de VW (guardadas proporciones, obviamente) decidieron dar su brazo a torcer y ahora el arreglo es más de fondo y costoso, cambiar el "short block" del motor.
Me pregunto, ¿será que algún propietario de vehículo Subaru aquí en Colombia, de los modelos mencionados en el TSB, tiene este problema?

Surface Treatment Change To Oil Control Piston Rings
2013-2014 Subaru Legacy and Outback Models with 2.5L FB Engine

2012-2013 Subaru Impreza and 2013MY XV Crosstrek Models with 2.0L FB Engine
Information regarding a major change to the repair procedures previously outlined in Service Bulletins 02-143-13R, 02-144-13R and 02-145-13R. These bulletins provided a repair procedure for the replacement of the piston rings to address verified concerns of unusual engine oil consumption.
Vehicles confirmed as having this condition which are within the supplied VIN ranges will no longer be repaired with piston ring replacement.
The revised repair procedure to address verified unusual oil consumption concerns on these specific vehicles will consist of replacing the engine short block assembly.
It is critical to understand the nature of the concern as reported by the customer and to confirm the actual condition prior to attempting repairs. Some oil consumption can and should be expected as a by-product of engine operation even where no concern exists.
Failure to recognize this and correctly diagnose the condition presented can result in unnecessary repairs.
For example: a vehicle which is presented with a report of a low engine oil level (as read on engine dipstick/ gauge or indicated by illumination of the low engine oil level warning lamp), which is at or near the time / mileage of the next service interval (based upon the date / mileage of the most recent oil change), is not representative of unusual oil consumption.
The information supplied in this bulletin is only applicable to vehicles within the specific production ranges of this publication exhibiting the condition(s) previously described.
IMPORTANT: Read and understand this bulletin COMPLETELY before starting an oil consumption test or initiating any repairs.
Concerns related to a possible oil consumption condition are generally initiated when the customer believes the engine oil level on the dipstick has dropped since the last time it was checked or when the low oil lamp illuminates. These types of complaints by themselves do not directly indicate a concern with the vehicle exists.
It is important to understand all the factors involved in order to make a sound decision regarding whether or not a repair is required or if an oil consumption test should even be started.
When speaking with customers about a reported or suspected oil consumption concern, always keep the following in mind:
Some engine oil will always be consumed as part of normal engine operation. How much and when it is consumed varies according to manufacturing tolerances, wear, and vehicle usage patterns.
