Lexus IS Oil Type & Capacity (2014–2027)

What Type of Oil Does a Lexus IS Take?

Every Lexus IS built since 2014 takes full synthetic oil. Which grade depends on the engine under the hood.

SAE 0W-20 — the 3.5L V6 and the 2.0L turbo

The 3.5L V6 takes SAE 0W-20. That covers every IS 350 since 2014, every IS 300 AWD, and the 2026 and 2027 IS 350, which is now the only IS offered. The 2.0L turbocharged four-cylinder also takes SAE 0W-20. That engine powered the IS 200t and the rear-wheel-drive IS 300 through the 2025 model year.

SAE 5W-30 — the IS 500 only

The 5.0L V8 in the 2022–2025 IS 500 F Sport Performance takes SAE 5W-30. It is the one engine in the IS range that does not use 0W-20, and 0W-20 is not an approved grade for it.

Which brands meet the Lexus specification?

Lexus does not publish an approved-brand list. The requirement is the specification, not the label. Use a full synthetic in the correct grade that carries the API Certification Mark — the starburst symbol on the front of the bottle. Any oil carrying that mark in the right viscosity meets the factory requirement. Genuine Lexus Motor Oil is formulated to it.

One point that confuses owners: the IS owner’s manual lists the oil grade as ILSAC GF-5. API retired GF-5 licensing on May 1, 2021, so you will not find a new GF-5 bottle on a shelf today. The categories that replaced it are backward compatible by design. A current API-certified 0W-20 satisfies the manual’s requirement.

What if 0W-20 isn’t available?

Lexus permits SAE 5W-20 as a temporary substitute during an emergency top-up. It must be drained and replaced with 0W-20 at the next scheduled oil change. That restores cold-start protection and the engine’s rated fuel economy.

Lexus IS Oil Capacity by Engine and Drivetrain

This is where most oil capacity guides get the Lexus IS wrong, in two ways.

First, drivetrain. On every V6 in the range, the all-wheel-drive car uses an enlarged oil pan to clear the front differential. It holds more oil than the rear-wheel-drive version of the same model.

Second, model year. The IS 350 switched from the 2GR-FSE V6 to the updated 2GR-FKS for the 2018 model year. The rear-wheel-drive capacity dropped by more than half a quart when it did. Fill a 2018-or-newer RWD IS 350 to the older figure and you overfill it.

Every figure above is the fill quantity with a new filter element. A drain performed without changing the filter takes less. The IS owner’s manual puts that difference at 0.2 quart on the rear-wheel-drive IS 350 and 0.5 quart on the all-wheel-drive car. Replacing the element at every service is standard procedure either way, so the with-filter figure is the one to work from. The dipstick is the final authority on any fill.

Which Oil Filter Does a Lexus IS Use?

The modern Lexus IS uses a cartridge-style filter element in a reusable housing cap. It is not a spin-on metal canister.

One element covers most of the range. Lexus specifies 04152-YZZA1 for both the 2.0L turbocharged four-cylinder and the 3.5L V6. That part number supersedes two older ones still in circulation, which is where a lot of ordering confusion comes from.

The genuine Lexus kit includes the pleated filter element, the O-ring for the housing cap, and the drain plug gasket. The plastic drain tool used to empty residual oil from the housing is a separate item, not part of the kit.

A non-OEM element can seat improperly, collapse under oil pressure, or filter less effectively than the engine was designed around. For more on how genuine components compare, see our guide to Lexus OEM parts versus aftermarket parts.

How Often Should You Change the Oil in a Lexus IS?

Because the Lexus IS requires 0W-20 full synthetic, it qualifies for the extended oil change interval.

Lexus defines special operating conditions specifically. They are driving off-road or on dirt roads, towing a trailer, making repeated short trips in temperatures below 32°F, and extensive idling. If none of those describe how you drive, the 10,000-mile interval applies.

One point that gets missed: the extended oil interval does not eliminate the 5,000-mile service visit. That visit still happens. It covers tire rotation, fluid checks, and inspection. The oil change simply moves to every other one. Our Lexus maintenance schedule guide lays out what happens at each interval.

How to Check the Oil Level in Your Lexus IS

1. Park on level ground and bring the engine to normal operating temperature.
2. Shut the engine off. Wait at least five minutes for oil to drain back into the pan.
3. Pull the dipstick and wipe it with a lint-free cloth. Reinsert it completely, then withdraw it again.
4. Read the level. It should sit between the lower and upper marks on the dipstick blade.

If the level reads above the upper mark, the engine is overfilled and oil should be removed. Overfilling can aerate the oil and stress seals. If you are not sure which capacity applies to your car, a VIN lookup settles it. Our service team can run one in a minute over the phone.

Common Questions About Lexus IS Engine Oil

What happens if you use 5W-20 instead of 0W-20 in a Lexus IS?

Lexus permits SAE 5W-20 as a temporary substitute when 0W-20 is unavailable. It will not harm the engine in the short term. But 0W-20 flows faster at cold startup and supports the engine’s rated fuel economy, so it should be drained and replaced with 0W-20 at the next scheduled oil change.

Does a Lexus IS 350 take the same amount of oil in RWD and AWD?

No. The all-wheel-drive IS 350 uses an enlarged oil pan to clear the front differential and holds 6.8 quarts with a filter change. A rear-wheel-drive IS 350 from 2018 or later holds 6.0 quarts, and a 2014 to 2017 car holds 6.6 quarts. The 2014 to 2015 IS 250 follows the older pattern at 6.8 quarts AWD and 6.6 quarts RWD. Verify on the dipstick after any fill.

Does replacing the oil filter change how much oil the engine needs?

Yes. The capacity figures published for the Lexus IS assume a new filter element, because the housing itself holds oil. The owner’s manual puts the difference at 0.2 quart on a rear-wheel-drive IS 350 and 0.5 quart on the all-wheel-drive car. Replacing the element at every oil change is standard procedure, so the with-filter figure is the one to use.

How often should the oil be changed under severe driving conditions?

Every 5,000 miles or 6 months, regardless of which oil is used. Lexus defines those conditions as off-road or dirt-road driving, towing a trailer, repeated short trips in temperatures below 32°F, and extensive idling.

What oil does the Lexus IS 500 take?

The 5.0L V8 in the 2022 to 2025 IS 500 F Sport Performance takes SAE 5W-30 full synthetic. It does not use the 0W-20 specified throughout the rest of the IS lineup. Confirm the exact fill quantity for your car by VIN with our parts department before servicing.
