Buick shares its platforms with other GM brands — LaCrosse and Lucerne with Impala and DTS, Enclave with Traverse and Acadia, Encore with Chevrolet Trax — but Buick trims add their own lighting, trim and suspension packages. A large share of the Buick parts we quote are for 1995–2011 LeSabre, Park Avenue, Century and LaCrosse with the 3.8-liter V6, plus classics from the 1960s and 1970s, so year and engine drive the fitment.
What’s different about Buick filters and fluids
- The 3800 V6 takes conventional 5W-30 and a common GM spin-on filter, while the 3.6 direct-injection engine requires dexos1 synthetic and a cartridge filter; the 1.4 turbo in Encore uses a cartridge filter and is sensitive to oil change intervals.
- Front-drive Buicks use the 4T65-E transmission (through 2009) with DEXRON VI and a pan-gasket filter kit, while later 6T40/6T70 transmissions use a different filter and DEXRON VI; DEX-COOL orange coolant is standard from the mid-1990s on.
- Cabin air filters are behind the glovebox on Enclave, LaCrosse, Regal and Encore, and many older LeSabre and Park Avenue models have a cowl-mounted filter that owners never knew existed.
