How big is the gas tank on a RX300?
The gas tank on a RX300 is about 19 gallons (roughly 72 liters), with small variations depending on the model year and market. This article lays out typical capacities and what can cause minor differences.
Overview of tank size and what affects it
The RX300’s fuel capacity generally hovers around the 19-gallon mark. Exact capacity can vary slightly by year, regional market, and measurement standard (US gallons versus liters).
The following figures reflect common specifications for RX300 models sold in North America and nearby markets, noting that exact numbers can differ by production run and country.
- US-spec RX300 (model years 2003–2006): approximately 19.0 gallons (about 72 liters).
- Other markets and occasional late-year variants: commonly about 18.5–19.0 gallons (roughly 70–72 liters).
Before listing the typical capacities, note that most RX300s built for the U.S. market have a tank close to 19.0 gallons (about 72 liters).
These figures represent standard factory tank sizes and may vary slightly due to production tolerances, optional equipment, or regional specifications.
Why tank size matters for RX300 owners
A vehicle’s fuel capacity influences driving range, refueling frequency, and trip planning. On an RX300, real-world range depends on driving conditions, payload, and driving style, so two identical cars could show small differences in how far they can go on a full tank.
Practical tips for verifying your exact capacity
To confirm the precise tank size for a specific RX300, consult the owner’s manual, check the original window sticker, or contact a Lexus dealer with the vehicle’s VIN. Dealers can pull exact specifications for a given production run and market.
Summary
In short: the RX300 typically features a 19-gallon fuel tank (about 72 liters), with minor variations by year and market. For exact figures on a particular vehicle, verify via official documentation or a VIN-specific spec sheet.
