using too much oil

[The devil]

when I don't put the drain plug back in when refilling during an oil change....plonker

You only make the mistake once, and in the future you'll check it 10 times before re-filling.

Ask me how I know

Many years ago I glugged 4 litres of fresh Mobil1 over my parents driveway. The only reason it wasn't more was because I noticed as I bent down to pick up the next bottle! I then had to catch a bus to go to halfords and get more.

when i realised my mistake, in my rush to pump the trolley jack back up i hadn't tightened the jack handle so it wasn't pumping at all...lol
