So the car on and off for a few weeks has showed up with the top up oil level on start up, theyre is abit of oil gathering around the spark plugs, checked with dipstick and oil is fine, so put it down to dodgy oil level reader as once driving around and starting the car again the next day for example it will say oil level correct, even after not topping it up, i keep checking the dipstick and all seems ok, am i right in thinking this is just a fault with the oil level reader? Got the car booked in for a service in 2 weeks so will have it checked over but should i be worried? Cheers
