Hmm hope I didn't do a bad thing

The crankcase actually has 5.2 quarts in it, including the transmission. You only drain 4.1 quarts when you include the filter on a regular oil change. If you added 1/5 of a quart (or .2 quarts) to make it good, you still had 5 quarts in the motor (or just over 96% of its rated capacity). I'm with Ferret, your good.

HUH?

HUH? Look in the owners manual. An oil change doesn't get ALL the oil out (and I wish it did). It removes about 80% of it when replacing the oil filter. The only way to get 100% of the oil out is to disassemble the motor.

As far as the 96% figure I came up with was having 5 of the 5.2 total quarts equals 96% (5/5.2=.96).

We dilute the remaining quart or so still in the motor with the 4 new quarts we put in at an oil change. If you wanted to get more of that old oil out without disassembly, here's what you do... Change the oil and filter. Take a couple mile trip. Change the oil (not the filter) again. Now you have removed 80% of the 'old' remaining quart out. Here's why...

The couple mile trip caused you to mix or infuse the original new oil change with the oil quart still in the motor, making your oil change a mix of 80% new and 20% old. With the second oil change, now you have removed 80% of the oil again but now the remaining quart that didn't come out is an 80% new/20% old mix. That translates to about 6-7 ounces of old oil out of a 166 ounce total in the motor, a greater peace of mind AND an expensive but extra clean oil change.

+1 it's why if you've ever looked at the "new" oil in the site glass after just about a 30 minute ride, it's already looking dingy.

All true. If you ever do an engine 'rebuild' you'll need that much oil to bring it to 'normal'.
