Just did my first oil change. I have been using Rotella T6 5-40 synthetic with a MO rating in my ST and XX and put it in the CB. Warming it up on the center stand after the change to fill the filter I noticed a knock in the lower end. Not a valve tick from the top. Taking it off the center stand onto the side stand it increased from the right side. Knock went away and went for a short ride 20mi. I noticed the recovery in the site glass was very slow. Put her on the center stand and ran it for about 10 minutes looking at the site glass. No oil in the window on level ground, turned off the motor and waited at least 30 seconds for oil to appear and then slowly inched up tho the full mark. The factory oil came out like water, this came out much thicker. This oil is much to heavy for this bike, either moving to slow through the oil cooler or returning from the top end.
Went to Dealer for Honda 10-30 synthetic & new filter. . Ran engine again on center stand even when cold you could see the oil level in the site glass bathing the lower end and when I turned the motor off return to the full mark was just about 10-15 seconds. Quite evident this bike requires a very thin motor oil.
Needless to say all bikes received oil changes today.
Please be careful and aware when using different oil then recommended.
I have read through the post in my thread. This is a HELP THREAD has nothing to do with what oil you should use or to promote same. I'm not a newbie, been around the block a few times and belong to a few forums. I only post things that have meat to them and may be helpful to others.

Interesting.
I use Honda oil in my Hondas and Honda filters too,( always have) but in 30,000 miles in my FZ-1 all I ever used was Shell Rotella T 5w40 and Walmart 7317 Supertech Filters.

Very interesting, too.
For the first oil change I went with Shell Rotella dino 15w-40 since its always warm here.
Have had good results using conventional Rotella in a Suzuki Bandit 1250 and second generation Yamaha FZ-1 and I was just researching switching to the full synthetic after 5,000 miles.
Will have to check out how the oil drains down after shutdown now.
UPDATE: This got me worried enough to go outside to the garage to check the oil level on the center stand (right on the mid point in the glass), crank up the motor (oil sucked into the system, not super fast but rapid enough), but yes after shut down I kept checking the glass and only after 3 minutes did I see some of the oil start pooling at the bottom of the glass.
I know the Shell Rotella both syn and conventional are good quality oils so must be something about the viscosity of the 40. Think I better go to Lowe's where I just spotted the conventional 10w-30 available to do a quick oil change before I ride again, then again maybe I'll go to O'Reilly's where they carry the Castrol motorcycle specific oils.
Just changed the oil and have maybe 100 -200 miles on it but I'm going to be safe and go with the next lighter grade of oil. Thankfully its still in the upper 80's here so maybe that's why I never heard any knocks. I stuck my ear right up to the engine just now when I did the quick test and no knocking so I hope I'm lucky.
Aloha,

FYI, ideally when you do an oil change you should try to manually fill the oil filter with as much oil as you can (without making a mess) before you install the filter. Then, after you've filled the engine with the proper amount of oil, turn over the engine with the kill switch off (if you have a bike that allows you to do this) to build up oil pressure (you'll know you're good to go when the oil pressure light goes off). Then flick the kill switch off and start the engine as per usual.
FWIW, I use Rotella T 5W-40 in my Honda Hawk GT and have had no issues.

use a length of heater hose up to your ear and probe the engine like a doctor and stethoscope.... You'll hear all kinds of stuff.

Not possible on the CB1100.

Went full synthetic on my first change. Noticed a difference quite quickly. Now just need to amortize the cost of 4 quarts of Honda Synthetic every service interval.

I'm not worried about the cost increase because not only will the fuel mileage be increased, but more importantly the longevity of the engine and transmission will be greatly increased. That makes it worth it to me.

Been using rotella for some time, just doesn't work with this motor. Lower end knock came 5 minutes after startup nothing to do with the build of oil pressure.

Oil is simply beyond my ability to fully understand. Since Honda Motor Co. has people they pay specifically for this purpose and who know what oil to use in this bike, why would you not just use what they recommend and your dealer sells?
