can you help with 2 problems. 1. when l put my foot on accelerator it makes a whirring noise, makes the car sound like a diesel engine.( but it is not) was told it is the tappets. ?? duh!!
no 2. how many miles do l get in the reserve tank.
why does mine have a r on the fuel gauge with a light that comes on. l only wanna know how far l get when the light comes on..

there only one tank you r playing games

when the fuel indicator is in the red expect to get around. 20miles, the most obvious thing causeing the noise would be an exhaust blow. as long as there is oil and water in the engine, should be ok to drive
but a mechanic will need to check over to besure

tappits are pushed up/down by the cams on a cam shaft
which inturn open/close valves to the cylinder head,
making sure oil is topped up should keep noise to a minimum, and noise usually dies down after engine has warmed and oil has circulated
8 valve engines do sound diesel like so do not worry to much
my n reg clio is the same it is done 77000 miles and still punchy for a 1.2

as for reserve fuel level i've never chanced it

hope this helps
