How much is that oil-doggie in the window?
« on: August 09, 2019, 05:56:35 pm »
I had a C10 for 80K once upon a time, and I don't recall this sort of thing happening.
So my "barn find" '99 has gotten three oil+filter changes in the first few days since rescuing it from the sidewalk where it had taken root for some unknown period of time.
Each time and still, I'm having a devil of a time getting the oil level right.  The first couple times, I add the new oil til the level showing in the window was about 2/3 of the way up.  Come back later and it's apparently overfilled by some amount, which I drained off.
Now that I have the bike running enough to go a few tentative miles it's still doing that: I set the oil level at 1/4 up from the bottom and the next day, it's over the top of the window.  Yes, I've waited some period of time before adding oil.
Is this some sort of characteristic I don't recall?

Are you completely draining the oil from BOTH the drain plugs, or just the rear one...?
when doing a filter change, and completely drained from both plugs, and filter removed/replaced,
the actual "fill amount" is 3 quarts + 5 ounces...
I seldom check the "window", as my bikes did not leak, only would "glance occasionally...."

I do this with the bike in the upright position, or on the center stand.

might want to measure just how much oil you "drained out" before filling..next time also.

Windows are inaccurate. Drain and filter change properly. 3qt and move on to other things.

Yes, the oil was changed properly.
I guess I'll just move on and not give it any more thought.

I had asked similar question after my first C10 oil change. Concensus here was just go by measure on changing and ignore site glass as noted by some above.

I have found since that the early morning check before start up gives a halfway mark in window. After running all bets are off and window reads all over the place till the bike cools and sits a considerable time.

Some one mentioned as explanation back then that oil has a convoluted return path back to sump glass and midway fill level. Never like the explanation as it does not explain "full" window. But that morning check always puts the dog to bed.

It helps to have a spot that is relatively level. When checking oil I the sight glass in my garage for instance I use the same spot for both my bikes because I found other places can lie. While the floor looks level, it really isn't when trying to get precise sight gauge measurements. Also, if the oil level is between the two marks you are good. But if you are like most people it has to be filled to the top line.

My current spot in the garage I can fill to the top line and I don't blow out oil. I'm sure there better scientific ways of checking flatness of he cement but I don't have time to mess with it. Rid safe Tim

I do the 3qts or 3 liters if I have an extra qt when I drain from both plugs and new filter. When I first got the bike I tried chasing the level at the sight glass until I checked here, now I don't bother.

3 quarts and then forget about it until the next oil change. 
Connies don't leak oil (generally), so no worries.

Yep #29 for when I ever put an unfilled C10 in service. Must confess as a C10 newbie first oil change was based on erronous info. Based on info still am over filling as in using 3.3 qts with filter change. Will have to rectify that on next change for sure. COG to the rescue again!
