hI, im tryin to find out why my fuel economy has droped. i have a 1997 vx 3.4 fuel/gas,
i use to get 400ks up to 435 out of a tank of gas from full to empty . at the moment when i fill up with about 73 lts of gas im batterling to get 365 out of it.
is it somthing to do with worm / v cold weather . or as there maybe somthing not corect .... motors done 200000 and ive noticed this over the last 2 to 3 months. same driving conditions. just cant sqeeze as much out of it as i could.... idd like to get it back up to getting 400 out of a tank agan. i once read somwhere about some sencer that can muck up economy ..... plug were done and oil change about 1 month ago.
any help would be great.
