well create a timer like this

Код:

SetTimerEx("refillcar",1000,1,"d",playerid);

then create the "refillcar"

Код:

forward refillcar(playerid);
public refillcar(playerid)
{
Fuel[playerid]++;
}

note that this will refill and not stop refilling, to make it stop after x times you need to create 3 new variables, 1 for the amount it needs to refill, another to count up to that number and another one for the timer.
like this.

top of the script

Код:

new refilltimes[MAX_PLAYERS];
new refillcount[MAX_PLAYERS];
new refilltimer[MAX_PLAYERS];

then in the /refill command

Код:

refilltimes[playerid] = 100-Fuel[playerid];
refillcount[playerid] = 0;
killtimer(refilltimer[playerid]);
refilltimer[playerid] = SetTimerEx("refillcar",1000,1,"d",playerid);

then in the timer

Код:

if(refillcount[playerid] == refilltimes[playerid]) killtimer(refilltimer[playerid]);
refillcount[playerid]++;
