Oil leak

Are you losing oil over time? If I didn't see spots on the driveway from a leak, maybe you're burning oil? If oil level is OK I wound't worry about it. If your losing oil over time you need to determine if it's a leak or if your burning it.

first of all thank you for the fast response! and i dont know if im losing oil as i just got this car a day ago. but oil seems low but i dont know how to read a dipstick so maybe im wrong lol. and the guy i bought if from said the mechanic said dont worry about it as long as the oils topped up. but if i dont fix it and just keep topping up, would i cause damage to the engine? thanks

Oil leaks would start with minimal leak and then progress on to bigger and faster leaks in due course. You might not need to worry for now but sooner or later you would still need to have it rectified.

If you don't see any oil on the floor, it means the leak could still be new.

As to cost, you need to verify locally as prices differs according to location and th shop you take to.
