How big is the gas tank on a 1999 RX300?
The 1999 Lexus RX300 uses a fuel tank with a capacity of about 19.8 gallons (75 liters). This is the widely cited figure in manuals and manufacturer specifications for the first-generation RX300.
Understanding this capacity helps owners estimate range between fill-ups and plan for refueling, especially given the era’s typical fuel economy and the availability of both front-wheel drive and all-wheel drive versions. The following notes break down the official figure and real-world implications for this model year.
Official capacity and documentation
The official capacity for the 1999 RX300's gas tank is listed as 19.8 gallons, equivalent to about 75 liters. Service manuals and Lexus/Toyota documentation for the XU20 RX300 generation consistently cite this capacity across model years in the late 1990s and early 2000s.
Notes on variation
There can be slight variations in capacity between different markets or production runs, but in the United States and most general reference materials, 19.8 gallons is the standard figure. Some sources may round to 19.5 or 19.6 gallons; the practical difference is minimal and primarily affects precise calculations rather than everyday use.
Practical implications: driving range
With typical mixed driving, the RX300’s fuel efficiency has historically ranged in the high teens to around 20 mpg, depending on drivetrain (AWD vs. FWD) and conditions. A full 19.8-gallon tank would therefore yield on the order of 320–400 miles (515–645 kilometers) before refueling in general use. Real-world range varies with driving habits, terrain, and maintenance.
Summary
The 1999 RX300 uses a 19.8-gallon (75-liter) fuel tank, a figure well-supported by official documentation for the era. This capacity typically translates to several hundred miles of range per tank, with actual range dependent on drivetrain and driving conditions. For owners, this means planning refuels around roughly the 320–400 mile mark under ordinary mixed driving.
