How many km in full tank of Toyota sienna?

Answer 1

There can be no direct conversion. A kilometre is a measure of length in 1-dimensional space while a tank contains a volume in 3-dimensional space. The two measure different characteristics and, according to the most basic principles of dimensional analysis, any attempts at comparisons or conversions between the two are fundamentally flawed.
If you are looking for the distance that can be driven on a full tank, the answer depends on many factors. These include:

• your driving style,
• the condition (tuning) of the car's engine,
• the road condition,
• whether or not you have the air-on on
• the condition of the car's tyres,
• how many passengers and other weight you are carrying.
