Direct answer

- • Oil/filter kit starts with: Engine oil (check owner's manual for type/quantity)
- • Keep the drain plug torque and change-interval notes in view while you work.
- • Approved brands and filter part details belong in the final fitment check, not the guesswork stage.
Before you order
Make the service method match the car
Oil jobs fail when the buyer grabs the wrong drain hardware or ignores the service method the car actually uses.
- • Confirm the filter and drain hardware listed on the page before checkout.
- • Use the service notes for your exact vehicle rather than a generic oil recommendation.
- • Keep the change interval and approved-brand notes on screen while you compare listings.
Next step

The 2012 SRX's direct-injected 3.6L LFX V6 holds a full 6.0 quarts of 5W-30 dexos1 oil and uses a cartridge-style filter in a cap on the passenger side of the engine. The 15mm drain plug is at the rear of the aluminum pan.
Engine oil: SAE 5W-30 dexos1 synthetic blend or full synthetic — capacity with filter is 6.0 qt (5.7 L)
Oil filter: ACDelco PF63E cartridge with O-ring — cap is on the passenger side of the engine near the front
Filter cap wrench: 32mm socket or ACDelco cap wrench — the cap is plastic and will crack if overtightened
Drain plug: 15mm hex head at the rear of the oil pan — torque to 18 ft-lb with a new gasket (GM 3536966)
Fill through the valve cover cap and wait 5 minutes before checking the dipstick — the LFX holds a lot of oil in the heads

What the Pros Prefer: 2012 Cadillac Srx Oil Service Workflow
Zero-mess shop procedure, drain plug safety, and filter gasket verification.
Engine Warm-Up & Safe Lift
Shop Tip:Run the engine for 3 to 5 minutes before draining. Warm oil flows much faster and suspends sludge and microscopic carbon particles for a complete drain.
Drain Plug Removal & Crush Washer
Shop Tip:Always replace the crush washer (aluminum or copper). Thread the drain plug in several turns by hand before applying a wrench to eliminate cross-threading.
Oil Filter Spin-Off & Pre-Lube
Shop Tip:Coat the rubber gasket of the new filter with a film of clean motor oil. Hand-tighten until the gasket touches the engine flange, then turn 3/4 turn further—never overtighten with a tool.
Refill & Level Verification
Shop Tip:Pour in 1/2 quart less than specified capacity first. Run engine 60 seconds, shut down on level ground for 3 minutes, then read dipstick to adjust to the top hash mark.
