How much oil does a Lexus GS 300 take?

Most Lexus GS300 models take about 5.9 quarts (5.6 liters) of engine oil for a full change with a new filter; exact capacity varies by year and engine variant.


Engine variants and oil capacity basics


The GS 300 has used several iterations of a 3.0-liter V6, most commonly the 2JZ-GE family. Oil capacity figures are quoted for a standard change with the filter; if you replace the filter, you still reach the same total capacity, but the precise number can shift slightly depending on the engine and market.


Capacity by typical GS300 configurations


Below is a representative range for common GS300 engines. These figures assume a full oil change with a new filter and using the manufacturer-recommended viscosity.



  • 2JZ-GE 3.0L V6 (the engine used in most GS300 models): approximately 5.9 quarts (5.6 liters) of engine oil, including the filter.


Note: Some markets or model years may show slight variation, typically within a half-quart. If your vehicle has a different engine variant or a performance-tuned version, the capacity may differ slightly.


How to confirm your exact capacity


To be certain, check the owner's manual under Specifications > Engine oil capacity, or consult a Lexus service document for your specific VIN. If you don’t have the manual handy, a dealership or trusted repair shop can confirm the exact figure for your vehicle.


Practical tips for changing the oil


Always use the correct oil viscosity as recommended by Lexus for your year and engine variant. After adding oil, run the engine briefly, let it settle, then recheck with the dipstick to ensure the level is within the proper range when the engine is warm.


Summary


In general, expect about 5.9 quarts (5.6 liters) of oil for a full GS300 oil change with a new filter. Exact capacity can vary slightly by model year and engine variant, so verify against your owner's manual or a service bulletin for your specific vehicle.

What oil does a Lexus GS 300 take?


The recommended oil for a Lexus GS300 is a 5W-30 viscosity grade, with most models preferring full synthetic oil. The required amount varies by model year, but it's typically around 5.7 to 6.8 quarts when replacing the filter. Always double-check your owner's manual or the oil cap for the most accurate specifications for your specific vehicle. 
Oil type and viscosity

  • Recommended: SAE 5W-30 is the preferred viscosity for most GS300 models. 
  • Type: Full synthetic oil is recommended for optimal performance and engine protection. 
  • Note: Some sources indicate that 10W-30 may be acceptable, but 5W-30 is generally the safer and more common recommendation. 

Oil capacity (with filter)
  • 2000 GS300: 5.7 quarts
  • 2006 GS300 (AWD): 6.8 quarts
  • 2006 GS300 (RWD): 6.7 quarts
  • 2003 GS300: Approximately 6.4 quarts (6.1 liters) 

Important tips
  • Check the cap: The oil cap on your engine often has the recommended viscosity printed on it. 
  • Verify with the owner's manual: Always consult your vehicle's owner's manual for the most accurate and specific information.
  • Change the filter: Always replace the oil filter when changing the oil. 
  • Don't overfill: After refilling, check the oil level and add more if needed. Do not overfill. 



How many quarts of oil does a 3.6 L V6 take?


A 3.6L V6 engine typically takes between 5 and 6 quarts of oil, but the exact amount varies by vehicle model, so you must check your owner's manual or the oil fill cap for the precise capacity. For example, some models like a 2013 Jeep JK require 6 quarts, while newer models like a 2020 Jeep Wrangler or 2018+ Jeep Wrangler JL may only take 5 quarts. 
Here are some general guidelines:

  • Check your owner's manual: This is the most reliable source for your specific vehicle. 
  • Look at the oil fill cap: It may have the required viscosity and capacity printed on it. 
  • Consider the model year: Newer vehicles, especially certain Jeep models, have different oil capacities than older ones. 
  • Change the oil filter: Always include an oil filter change, as this is part of the full oil capacity. 
  • After refilling, check the level: After you've filled the engine with oil, use the dipstick to check the oil level and add more if needed to reach the "full" line. 



How many quarts of oil does a Lexus GS300 take?


A Lexus GS300 takes 5.7 quarts of oil with a filter change, according to AMSOIL. This is for models with the 2JZ-GE engine, such as the 1999-2004 models. Always check the oil level after refilling to ensure it is within the correct range. 

  • For 1999-2004 Lexus GS300 models: The capacity is 5.7 quarts when the filter is changed.
  • Always check the level: After you pour in the oil, check the dipstick and add more as needed to reach the "full" mark without overfilling.
