Lexus GX fluid capacities by year
Capacity is year- and engine-specific. Figures are service fills verified against factory service specifications; a dash means that configuration isn't verified yet, so check your owner's manual. Automatic transmissions are left out on purpose: they use a temperature-controlled check-level fill with no honest single number.
