Default Oil Quantity/Draining Question.

Just curious...how much oil is left in the engine and how much completely makes it to the tank? This is on a '15 Slim. I noticed a drain plug on the bottom right side of the engine case just underneath from the cam cover that looks identical to the tranny drain plug. Didn't know if this was possibly to get out any last bit of oil that sits in the crank. Just a thought. I thought this motor took more than three quarts. Thanks for the help guys.

Leave that plug alone unless you suspect sumping. My 09 takes less than 2.5 quarts for a change so don't be too concerned about that.

I do a complete oil change when I do mine and I get a little over 3 1/2 quarts out of it. I have a oil cooler and a little extra line so that might add a tiny bit to it. I have a ton of money in my motor and I will not leave any bad, dirty oil in it at all, ever!

Define "complete oil change" then if you're doing something above and beyond draining the tank and changing the filter.

I accidentally removed mine when I did my first oil change, thinking that was the main drain plug. Less than half a quart came out. You are not supposed to remove it if possible as it can crack the case easily if you over tighten it, or you could strip it easily.

The tank drain is on the right side of the bike...the kickstand is on the left...if you drain the oil with the bike on the kickstand...you will leave a lot of oil in the tank...

Default oil drain

Check out some of the threads about the oil scavenger. I think that method works great. I like getting all of the dirty oil out before refilling. Just my opinion.
