I always drain when warm and let it stand for about an hour.  Clean all the surfaces before installing the covers.  Soak the new filter.  Install two quarts of the oil of your choice and four ounces of marvel mystery oil.  This should suffice for about 2500 miles.  Works for me now over seven thousand miles on the C-5---I feel the marvel oil greatly improves the shifting.

Scotty Brown - You may want to use caution when adding Marvel to your wet clutch system on your bike.

This is directly from the Marvel Mechanics Forum: http://www.marvelmysteryoil.com/index.php/forums/viewthread/372/

“While Marvel Mystery Oil is compatible with synthetic, semi-synthetic and petroleum based oils, we do not recommend that it be used in motorcycles with a wet clutch.  Marvel Mystery Oil is such a good friction modifier that it could have an impact on the transmission and caused some shifting concerns.”

I measured how much oil was drained from by GT:  About 5 5/8 pints measured using a graduated pitcher used to mix 2-stroke fuel.  That converts to about 2.6 quarts.  Silly me, I thought the 2 quarts of lube I got from nField in their oil change kit was enough since I found the kit in the "Continental GT 2014  >   Oils  >   Filters & Chemicals  >  Complete Oil Change Kit" page of their on-line catalog and I didn't read the fine print there.  The fine print:

"**The G5 kit is for G5 models fitted with 2-hole oil filter cover. If your G5 has a 3 hole oil filter cover, order the C5,B5,GT kit (Z92102)**

 ** Newer models will have a second oil drain plug; in some instances this style of case will require more than 2 quarts of oil. We have added a 3 quart option for customers that may need more oil.** 

It's also in the owner's manual: 2.75 quarts (dry fill) which I also didn't look up before hand.  My bad, all round. Sorry!

For those doing an oil change for the first time, here's a helpful narration published in "Motorcycle Classics" magazine, which is on my short list of great magazines:

Very interesting and cool article.  My 2014 C5 will blow oil into the air cleaner with 2.5 quarts of oil put back in it, so I stick to 2 quarts and end up in the same spot on the sight glass as the picture in the article. 

I can't imagine the bottom end is different in the GT, but the air cleaner assembly sure is. 

Good to know.

I'm disappointed in that "how-to" article.  I guess it's mostly ok, but I'm mildly annoyed that they couldn't identify the tiny o-ring from the oil filter cap - that gets a 

But I'm seriously concerned about the paragraph which begins,

The other thing that struck us is the poor location of the crankcase breather tube, which is mounted directly forward of the screw-in oil filler cap. That wouldn’t be so bad if the tube didn’t immediately elbow 90 degrees rearward. Because of its location, it has to be pushed out of the way to remove and install the filler cap.

This gets a  !  Whoever wrote the article can't tell the difference between a breather tube and a bundle of wires?!?  C'mon, guys...

[gizzo]

yeah, but we know what they meant....

[phoenixt]

I noticed the breather tube mistake too. I just figured that they probably wrote the article from memory a few days or weeks after the oil change and forgot the location of each.

At least I would hope.

If the smallest O-ring in the kit is meant for the oil filler cap, then it isn't meant for a Continental GT which has an oil filler cap with a diameter of around an inch:


I was caused a lot of trouble by this kit because it isn't specifically for GTs but shows up in the section of nField's online catalog with other parts specifically for GTs (can I be sure?), and I trusted nField Gear to get it right. They could cause us a lot fewer of these difficulties if they would have the "complete oil change kit" for GTs that's in the GT section of the catalog showing 3 quarts of oil and one less O-ring, with the associated part number. 

Including comprehensive instructions written in American or Commonwealth English would help as well, since a lot of "GTers" are far removed from dealers and on their own for maintenance.

[REpozer]

Wow!
I thought the tricky things were, rebuilding front shocks, trying to dial in carburetor jets, stop a primary leak, etc.
Oil change?
Never you mind all that.

[Guaire]

The small O ring fits behind the bolt holding the spring.

[Guaire]

nField Gear has it right. My o ring was visible as its edge was peeking out from behind the bolt. Usually it isn't necessary to change it out every oil change, but mine needed to go.
  "...that o ring. Mine was deformed and sticking out between the plate and the screw. That's why the o ring is deformed in the photo. Thought it could eventually break up. After buying the 5 pack, I've got a lot of o rings to throw around."

Uncle Billy - just in case this is a reply to my comment... I wrote oil filter cap, not oil filler cap.  I had to double check to make sure I didn't misspell it!  The filter cap has the small o-ring sandwiched in the stack.

[Uncle Billy]

Right, my mistake.  Been a lot of them lately...

[ROVERMAN]

Regarding MMM oil. I have used it in my engine/trans and fuel tank from day one, no complaints here.
