Oil & filter for the 2024 Lexus IS
You need 0W-20 oil (6.8 quarts with a filter change). Buy the oil and a filter together; a DIY oil change takes about 30 minutes, or any shop can do it.

Oil is sold in 5-quart jugs and single-quart bottles, and almost no engine takes a round number, so a single jug is usually either not enough or more than you need. Here is the plan for each engine in this vehicle:
| Engine | Needs | Buy | Left over |
|---|---|---|---|
| 200t ASE30 | 4.9 qt (4.6 L) | 1 × 5 qt jug | 0.1 qt |
| 250 2WD USE30/GSE31 | 6.6 qt (6.2 L) | 1 × 5 qt jug + 2 × 1 qt | 0.4 qt |
| 250 AWD USE30/GSE31 | 6.8 qt (6.4 L) | 1 × 5 qt jug + 2 × 1 qt | 0.2 qt |
| 300h AVE30 | 4.8 qt (4.5 L) | 1 × 5 qt jug | 0.2 qt |
| 350 2WD GSE30 | 6 qt (5.7 L) | 1 × 5 qt jug + 1 × 1 qt | none |
At 4.9 quarts this sits close to the 5.5-quart median across the vehicles we hold, so it is a typical, inexpensive oil change. These figures include a filter change. If you are only draining the sump and reusing the filter you will need slightly less, so add most of it, run the engine, and finish on the dipstick rather than pouring the whole amount in.
Which engine do you have?
The 2024 Lexus IS was sold with 5 different engines, and they do not hold the same amount of oil - the spread is 4.8 to 6.8 quarts, a difference of 2. Every engine takes the same grade, so the grade is not the risk here, the amount is. Check the engine badge or the label under the hood before you buy, and confirm on the dipstick after refilling rather than trusting the quart count alone.
What 0W-20 actually means
The 0W is the cold rating - the W stands for winter, and a lower number means the oil stays thin enough to pump on a freezing start, which is when most engine wear happens. The 20 is how thick the oil is once the engine is hot and at operating temperature. So 0W-20 flows like a 0-weight oil on a cold morning and protects like a 20-weight once warmed up.
0W-20 is one of the mainstream grades, covering 23.7% of the engines we hold specs for (5W-30 is the most common at 51.4%). Every parts store stocks it.
Full synthetic is worth it here, and at this point it is mostly what is on the shelf anyway. What matters more than the brand is that the bottle carries the current API service rating and the grade above. See how this grade compares across the US fleet.
Can you use a different weight than 0W-20?
Going thicker than 0W-20 is the common mistake, usually on the theory that heavier oil protects better. On an engine designed around a low-viscosity grade it does the opposite: the oil passages and variable-valve-timing hardware are sized for a thin oil, so a heavier grade flows more slowly on startup, costs you fuel economy, and on some engines gives the manufacturer a reason to decline a warranty claim. Use the specified grade.
The exception most people are thinking of is an older, high-mileage engine that has started using oil between changes. Going one grade heavier there is a real, if temporary, way to slow that down. It is a way of managing wear that has already happened, not a way of preventing it, and it is not a reason to deviate on a healthy engine.
When to change it
On full synthetic, most vehicles land in the 7,500-mile range under normal use and closer to 5,000 under severe use. Severe is not unusual driving - it means short trips that never fully warm the engine, stop-and-go traffic, towing, dust, or extreme heat or cold. If your car is mostly doing school runs and errands, you are in the severe column, which surprises people. If your car has an oil-life monitor, trust it over any fixed number, because it is watching how the engine is actually being used.
These are typical intervals for guidance. Your owner's manual is the authority for your exact vehicle - some engines, oils, and fluids have longer or shorter intervals.
Frequently asked
How much oil does a 2024 Lexus IS take?
It depends on the engine: 200t ASE30 takes 4.9 qt; 250 2WD USE30/GSE31 takes 6.6 qt; 250 AWD USE30/GSE31 takes 6.8 qt; 300h AVE30 takes 4.8 qt; 350 2WD GSE30 takes 6 qt.
What kind of oil does a 2024 Lexus IS use?
0W-20 full-synthetic motor oil.
How many jugs of oil do I need for a 2024 Lexus IS?
It depends on the engine. For the 200t ASE30: Buy 1 × 5-quart jug (5 quarts). That covers the 4.9 quarts this engine needs and leaves about 0.1 of a quart spare for topping up.
Can I use a thicker oil instead of 0W-20?
Going thicker than 0W-20 is the common mistake, usually on the theory that heavier oil protects better. On an engine designed around a low-viscosity grade it does the opposite: the oil passages and variable-valve-timing hardware are sized for a thin oil, so a heavier grade flows more slowly on startup, costs you fuel economy, and on some engines gives the manufacturer a reason to decline a warranty claim. Use the specified grade.
Is 0W-20 a common oil grade?
0W-20 is one of the mainstream grades, covering 23.7% of the engines we hold specs for (5W-30 is the most common at 51.4%). Every parts store stocks it.
Do all 2024 Lexus IS engines take the same amount of oil?
No. Capacity ranges from 4.8 to 6.8 quarts depending on which engine the car has, though they all use the same grade. Match your exact engine before buying.
How often should a 2024 Lexus IS have an oil change?
On full synthetic, plan on roughly 7,500 miles under normal driving and about 5,000 under severe use - short trips, stop-and-go, towing, dust, or extreme temperatures. If the car has an oil-life monitor, follow it rather than a fixed mileage, because it reacts to how the car is actually driven.
