Follow these steps carefully
The 2016–2022 RX 350 (4th gen AL20, 3.5L 2GR-FKS V6) takes 0W-20, 5.7–5.8 quarts. CRITICAL: CARTRIDGE filter (not spin-on) — 04152-YZZA1 element kit and cap wrench. You'll need: 6 quarts, 14mm socket. Capacity: 5.8 qt WITH tow package, 5.7 qt WITHOUT — check yours.
Remove the underbody panel for drain plug access. Position the drain pan under the 14mm drain plug and remove it. The 5.7–5.8 qt sump takes a while — ensure your pan holds 6+ quarts. While it drains, locate the cartridge filter housing under the engine.
Remove the plastic cartridge housing cap with the correct cap wrench — the plastic cap is known to CRACK, so don't overtighten. Remove the old cartridge (04152-YZZA1), install the new element with the O-ring properly seated, and reinstall the cap snugly.
That plastic housing cap is the RX 350's Achilles' heel — I've seen them split from one ham-fisted turn with the wrong wrench. Use the proper cap wrench, snug it, and stop. Or just buy the aluminum cap once and never think about it again.
Reinstall the drain plug with a NEW gasket and torque to 30 N·m (22 ft-lb). Use an OE drain plug. Don't over-tighten — 30 N·m (22 ft-lb) with a fresh gasket is the spec.
Add 0W-20: 5.8 quarts with the tow package, 5.7 without. Check the dipstick — it should read at the full mark. Don't overfill — the 0.1 qt matters on the dipstick.
Start the engine and check for leaks (cartridge housing and drain plug), then recheck the level after 30 seconds — the cartridge absorbs oil. Top up if needed. Lexus interval: 10,000 miles / 12 months with synthetic.
Test your repair before closing everything up. If something doesn't work right, double-check your steps.
