3 1/2 qt of oil is all you need to put in when doing a oil change, any more oil then that and you will get oil spitting out of the air cleaner. The
HD LCD dip stick is pretty much junk IMO and it is not accurate on oil level or oil temp. I have one and I just pull the dipstick to get a good reading and I have a in dash oil temp gauge that gives me a accurate reading.
