Hi all, 
 
	 
 
	Recently just bought my nissan, 
 
	 
 
	Been driving round for a week now after getting back from work i checked the oil level on this amazing dip stick. 
 
	 
 
	I let the engine cool down 15 mins or so at least. 
 
	 
 
	Level on dipstick from the L position was around say 1-2 letter above that.
 
	 
 
	I have now put around 400ml of oil in. 
 
	 
 
	Now after letting her cool down Reading is about 1 letter higher than the H, 
 
	 
 
	Do I have a real problem on my hand and need to drain ASAP?
