📖Buick Encore GX I: stylish subcompact crossover demanding strict wet-belt and oil discipline

Positioned above the standard Encore, the first-generation Buick Encore GX arrived in 2019 on GM's VSS-F platform, offering sharper styling, increased passenger room and modern driver aids. Combining agile urban proportions with refined motorway cruising manners, it targets small families and commuters. Ensuring lasting reliability requires methodical Buick Encore GX maintenance, particularly concerning engine lubrication and transmission care.

Engine choices comprise the 1.2-litre (LIH) and 1.3-litre (L3T) three-cylinder Ecotec turbo engines. Crucially, these engines utilise a specialised wet timing belt running in engine oil, making strict adherence to GM dexos1 Gen 3 oil specifications essential to avoid belt degradation. Front-wheel-drive models use a continuously variable transmission, while all-wheel-drive variants feature a responsive 9-speed automatic gearbox.

When inspecting a pre-owned Encore GX, examine the oil filler neck for rubber particulate residue, test low-speed transmission smoothness, and ensure the electronic brake booster operates without warning chimes. A well-serviced Encore GX provides quiet, economical everyday transportation.
