Hi
how to know petrol is reached to reserve point in Wagon R VXI
If any indication is displayed.
What is reserve tank capacity.

Please answer.

Dear,
pls read the booklet/ service manual you got with your vehicle. The reserve is generally 4-5 litres but do not depend on that coz the ''Kachra'' means fime particles (residual) rests at the bottom & they may damage your engine. So better full your tank & move it gives good avarage on tank full.

The reserve fuel is indicated as the remainder fuel in the bottom of the tank which is in the shape of a trough,now all the residual matter like some solid particles that may have entered into the tank by some means r also present in this zone.The reserve capacity when in use the car is fuel meter needle will be just below the lower red line indicating that the fuel tank has gone empty & needs a fill as soon as possible.

Do not risk using the reserve fuel,it is not a good practice.Might do damage to engine if air were to flow into it.
