Find GX470 oil type and capacity
The short answer
The Lexus GX470 was sold for the 2003 to 2009 model years. It uses the 2UZ-FE, a 4.7-liter V8 gasoline engine. Commonly published service figures list SAE 5W-30 engine oil and a capacity of about 6.6 US quarts (roughly 6.2 liters) when the oil filter is replaced at the same time.
No owner's manual or factory service data was supplied for this article, so these figures are not verified against Lexus documentation here. Confirm them in the owner's manual for your model year and market before you buy oil or refill the engine.

Details that can change the answer
Filter change or not: The published capacity assumes a new filter. A drain without a filter change takes slightly less oil. Oil grade and certification: The manual names an API service category or ILSAC standard as well as a viscosity. The required grade can depend on model year, and this article had no source data to confirm it. Climate and market: Some owner's manuals allow alternative viscosities for particular temperature ranges or regions. Check the temperature chart in the manual for your vehicle. Refill amount versus listed capacity: Oil left in the engine after draining means the exact amount you need can differ from the listed figure. Treat the dipstick reading as the final check.
How to confirm the specification on your vehicle
Owner's manual: Look in the specifications or maintenance section for engine oil capacity and recommended viscosity. This is the primary source for your vehicle. Oil filler cap: On many Toyota and Lexus engines, the cap on top of the engine is marked with the recommended viscosity. Check whether yours has a marking, and if it does, compare it with the manual. Model and model year: The model year is on the vehicle registration and title. The VIN plate is visible through the lower corner of the windshield on the driver's side. Use the model year to make sure you are reading the correct manual or service data. Dealer or service records: A Lexus dealer can look up the factory specification from the VIN if the manual is missing.
Checking the oil level after a refill
Add slightly less than the listed capacity first. Run the engine briefly and check around the filter and drain plug for leaks. Then switch the engine off and wait a few minutes so the oil drains back into the pan. With the vehicle on level ground, pull the dipstick, wipe it, reinsert it fully, and read the level against the low and full marks. Top up in small amounts until the level reaches the full mark, and do not overfill.
This article does not describe the exact dipstick or filter locations on the GX470 because no layout documentation was supplied. Consult the owner's manual or a model-specific service guide for those locations, and for any underbody panel you need to remove to reach the filter.
