Many years ago a young lad who lived near me asked if could look at his car.
It was blowing clouds of thick blue smoke out.
I asked him what had he done recently, hoping to get an idea if he'd had any mechanical mishaps
He replied that he noticed that the oil was low and he'd topped it up .
We started the car, and sure enough, enough smoke was coming out the back to obscure half of england..
No mechanical noises were evident when running , just clouds of smoke ...
Worn bores & rings sprung to mind, I asked him if the car was consuming a lot of oil... he replied that it was the first time he'd topped it up in over a year.
hmmm
Anywway i pulled the dipstick and got my first warning sign,
the oil level was half way up the dip stick....
wiped it clean and popped it back in.. and pulled it out agian, and the reason for all the smoke was evident ...
Dark black oil on the bottom of the dipstick, and clear new oil all the way up the rest of the dipstick.
The lad thought you topped it up so the dark line moved up the dipstick, so had added 5 litres when in reality 1 litre would have done
We did an oil change, and normal non cloudy service was resumed lol
