The 1996 Buick Skylark has no open NHTSA recalls. Owners report 8 recurring issue clusters, led by “Engine coolant leaks and head gasket damage.” Buick uses the GM Oil Life System: an algorithm tracks engine revolutions and temperature, then lights the change-oil message — typically every 7,500 miles in mixed driving, capped at 12 months, using dexos-approved oil. Current Encore GX and Envista run 1.2/1.3L turbo three-cylinders where oil quality matters more than volume drivers expect (the sump is small and turbo-heated). Front-drive models pair to a CVT with a published fluid interval — it is not a lifetime part.
No open recalls on file. NHTSA lists no unrepaired safety recalls for this year, make and model. A recall can be issued at any time, and a specific car can still have one open — check yours by VIN at nhtsa.gov/recalls.

Critical for safety and preventing major damage
Change when the Oil Life System calls it — typically around 7,500 miles, never beyond 12 months. dexos1 0W-20 on modern engines. Small-displacement turbos (Encore GX, Envista): don't stretch the indicator.
Estimated cost — typical U.S. ranges
Dealer
~$120–$160
Shop
~$85–$115
DIY
~$25–$55
Full synthetic costs more than conventional. 5-quart 0W-20 + filter is the typical bill.
Rotate every 7,500 miles with the oil change — GM pairs the two in its schedule.
Estimated cost — typical U.S. ranges
Dealer

Shop
~$60

Free
Often free at the shop where you bought the tires — worth asking before paying.
Inspect pads, rotors, and lines at every service. Older Centurys: check rear drum adjustment and parking-brake cables, which seize with age.

Free
Most shops do this free as a courtesy with any service. Don't pay separately if you can avoid it.
FWD Encore GX and Envista use a CVT: GM schedules fluid replacement around 45,000 miles under severe service — which includes most city commuting. AWD Encore GX uses a 9-speed automatic instead (see transmission fluid).
Estimated cost — typical U.S. ranges
Dealer
~$360–$500
Shop
~$255–$355
DIY
~$80–$180
CVT fluid is manufacturer-specific and pricey — do NOT substitute conventional ATF.
Keeps your vehicle running smoothly and efficiently
Conventional automatics (Century's 4T65-E, Regal's Aisin, AWD Encore GX's 9-speed): GM lists 45,000 miles severe / longer normal. Older Buicks respond well to a simple drain-and-fill — avoid pressure flushes on high-mile units.
Estimated cost — typical U.S. ranges
Dealer
~$330–$500
Shop
~$235–$355
DIY
~$60–$180
Some sealed transmissions have no dipstick — fill is precise and best left to a shop. Many drivers can still DIY drain-and-fill.
Small-turbo three-cylinders (Encore GX, Envista): roughly every 60,000 miles — check the manual. Older 3.1/3.8 V6s: iridium plugs last to 100,000 miles.
Estimated cost — typical U.S. ranges
Dealer
~$285–$390
Shop
~$200–$275
DIY
~$25–$100
Iridium plugs cost more but last 100k+ miles. V6/V8 access varies wildly — some are tough.
GM schedules replacement around 45,000 miles; inspect at every oil change in dusty regions.
Estimated cost — typical U.S. ranges
Dealer
~$60–$95
Shop
~$45–$70
DIY
~$15–$40
5-minute job on most cars; the airbox lid usually has clips, no tools needed.
Inspect from 60,000 miles; replace on cracking or glazing rather than mileage alone.
Estimated cost — typical U.S. ranges
Dealer
~$195–$235
Shop
~$135–$165
DIY
~$20–$50
DIY-friendly if you can reach the tensioner. Inspect for cracks rather than swap on a strict mileage interval.
Extends the life of your vehicle and improves comfort
Replace roughly every 22,500 miles per GM's schedule — behind the glovebox on modern Buicks.
Estimated cost — typical U.S. ranges
Dealer
~$60–$95
Shop
~$45–$70
DIY
~$15–$40
Usually behind the glovebox. Shops charge labor for a 10-minute job — easy DIY win.
Dex-Cool is rated 5 years / 150,000 miles. On older 3.1/3.8 V6s, intake-gasket seepage was the classic failure — check coolant level and condition at every oil change on a Century.
Estimated cost — typical U.S. ranges
Dealer
~$285–$330
Shop
~$200–$235
DIY
~$25–$60
Use the manufacturer-specified coolant — wrong color/chemistry can damage the cooling system.
Test annually after year 3. Stop-start-equipped Encore GX/Envista use AGM batteries — replace like-for-like, not with a cheaper flooded battery.
Estimated cost — typical U.S. ranges
Dealer
~$225–$390
Shop
~$160–$280
DIY
~$130–$250
Most auto-parts stores test and install batteries free with purchase. Skip the dealer markup.
