I have a 3 month old Ford Fiesta 1 litre Eco car. When I check the oil the dip stick is over the maximum limit. I took it back to garage and they say that you do not check the oil when the engine has not been run, you run the engine for a couple of minutes and then check. They said the engine oil expands when stationary. This is contrary to the manual that states check when not in use. Which is correct?
You should start engine switch it off and check the oil level, the oil does not expand but all the oil drains back to the sump, but it should take a few hours for the oil to drain back. so start engine stop it and check the oil level,
