2020 Lexus RX Maintenance Schedule
Here are the 2020 Lexus RX's service intervals, drawn from the manufacturer's published maintenance schedule — the key services, when each is due, and what each one does. Add your Lexus RXto your free BoxKitz garage to track exactly what's due based on your mileage and build a parts kit with price comparisons.
Service intervals
| Service | Every (km / mi) | Or every |
|---|---|---|
| Oil & Filter Change | 16,000 km / 10,000 miFull synthetic (grade varies by engine — see Fluids & capacities below). Toyota's severe-service schedule (short trips, towing, dusty roads) shortens this to 8,000 km / 5,000 mi or 6 months. | 12 months |
| Tire Rotation | 8,000 km / 5,000 mi | 6 months |
| Engine Air Filter | 48,000 km / 30,000 miMore often in dusty conditions. | — |
| Cabin Air Filter | 48,000 km / 30,000 miMore often if you drive in dust or heavy pollen. | — |
| Spark Plugs (Iridium) | 192,000 km / 120,000 mi | — |
| Engine Coolant (SLLC) | 160,000 km / 100,000 miFirst change at 160,000 km / 100,000 mi or 10 years; every 80,000 km / 50,000 mi thereafter. | 120 months |
| Transmission Fluid | —Toyota fills these for life and lists inspection only — no scheduled change under normal use. Consider a change around 96,000 km / 60,000 mi if you tow or drive in severe conditions. | — |
| Brake Fluid | —Toyota inspects brake fluid at each service rather than on a fixed interval; a change every ~3 years is common practice. | — |

| Tire Rotation | 2.5×/yr | $0–$0/yr |
Rough estimates in CAD for scheduled-maintenance parts and fluids, based on typical prices — not live retailer quotes, and your costs will vary. Wear/replacement items (brakes, tires, battery) and diagnostics aren't included.
Fluids & capacities
Capacities are "with filter" and vary by engine — check your Lexus RX's engine option below.
| Engine oil | 0W-20 full synthetic — 6.4 qt (6.1 L) |
| Engine coolant | Toyota Super Long Life Coolant (SLLC, pink) |
| Spark plugs | Iridium, ~120,000 mi service life |
| Automatic transmission fluid | Toyota Genuine ATF WS8-speed automatic. |
| Differential / transfer case | 75W-85 GL-5 gear oil (4WD/AWD)AWD models. |
| Brake fluid | DOT 3 |
Confirm the grade and capacity against your owner's manual before servicing — figures can differ by trim, drivetrain and market.
What each service does
Oil & Filter Change
Fresh oil and a new filter keep the engine lubricated and cooled. Toyota specifies a low-viscosity full-synthetic oil on these engines.
Tire Rotation
Rotating tires every 8,000 km / 5,000 mi (about every second oil change) evens out tread wear so they last longer and grip predictably.
Engine Air Filter
A clogged air filter chokes the engine and hurts fuel economy. Toyota schedules replacement around 48,000 km / 30,000 mi.
Cabin Air Filter
Filters dust and pollen from the air inside the cabin. Toyota lists replacement around 48,000 km / 30,000 mi.
Spark Plugs (Iridium)
Toyota's long-life iridium plugs are rated for about 192,000 km / 120,000 mi. Worn plugs cause misfires, rough idle and poor economy.
Engine Coolant (SLLC)
Toyota Super Long Life Coolant is designed for an extended first interval, then more frequent changes to keep its corrosion protection.
Transmission Fluid
Clean fluid keeps shifts smooth and protects the transmission. Toyota does not publish a fixed replacement interval for normal driving.
Brake Fluid
Brake fluid absorbs moisture over time, which lowers its boiling point and softens the pedal.
These intervals are drawn from the 2020 Lexus RX's manufacturer maintenance schedule for normal service. Your vehicle's owner's manual remains the final authority, especially for "severe service" conditions like towing, short trips or dusty roads. BoxKitz links you straight to the manufacturer's manual and live recall data once you add the vehicle.
