Before You Buy Oil
How to Use This Model Page
Choose the exact model year first, then match the engine shown on your emission label, VIN decode, or owner manual.
The capacity values are listed with a new oil filter. No-filter refill amounts may be lower when the source publishes them.
Use the detail page for filter part numbers, change intervals, torque specs, and source notes when available.
Why RL oil capacity can change
The Acura RL nameplate can cover multiple engines, redesigns, trims, and service procedures. These checks help avoid using the right model but the wrong engine or year.
Generation changes
A redesign can bring a new engine, oil pan, filter housing, or hybrid system that changes the refill amount.
Engine options
Turbo, hybrid, diesel, V6, and base engines may share the same model name but require different oil quantities.
Oil type requirements
Known viscosities on this page include 5W-20; still check the manual for any approval code.
Final level check
After the first refill, run the engine briefly, wait for drain-back, then confirm the oil level before driving.
