yes the volume is one litre between min and max mark as mentioned in the manual. i think i will get the compression checked but its impossible to find a good garage in our area so will have to wait for some time. thanks. italia just opened the spark plugs but cud not take them out as i did not have the proper tool. i could only reach to the top end of the plugs. will take the car to my mechanic and ask him to check. you guys are really helpful. besides i googled for the causes of oil consumption and nowhere is it mentioned EGR can be the cause. are you sure 1.4 has a EGR. then i will surely like to get it cleaned.
