I put too much oil in my diahatsu cuore, the oil level is about 9mm above the full level, what can i do? Please!
Hello A small amount of overfill like this isn't a particularly high amount possibly about 0.5 litres? however if you're worried then I'd simply open the drain plug on the sump ( with a gloved hand) and let it drain for a few seconds before replacing the plug then give it 10 minutes to settle and re-check the level

Thanks, ***** ***** help. I don't know how much it is, just how high the mark is on the dipstick. With removing the drain plug, is that something I can do easily? The call out mechanic seemed to think it needed to be raised up/taken to a garage.

Looking online, two pieces of advice I found were:
Drive it slowly.
Take the oil cap off and rev the engine for 5 seconds.
Would either of these work?
I'm not sure I'll be able to take the sump cap off.
Hello driving slowly and removing the oil filler cap and running the engine won't have any effect to access the drain plug you need a jack to lift the car up slightly, just enough to slide a washing up bowl underneath to catch the oil and then you'll see a large nut on the bottom of the engineundo this and the oil will gush out, then put the plug back in after the oil has run out for a few seconds if you're not confident doing this then any small garage can tackle it for you

Ok, I appreciate all your help. Unfortunately I have to leave for work before garages are open. I won't be able to jack the car up, so think I'm going to have to risk it. If you reckon being 9mm above the full line isn't too drastic (and I appreciate you can't give any guarantee) then I'll drive it and see what happens. Any advice for how I should drive it? Or what I should look for if something is wrong? If I stop when I see smoke, will I still have messed up my car?
hello you should be fine to drive it, providing you're not after any high speed runskeep the engine revs low and you should be fine at worst the engine will throw a lot of oil mist out through breather system which then gets drawn back into the engine so it may start to misfire if its particularly bad and hte spark plugs will then have to be removed and cleaned
