About 20K, formulated like most motorcycle oils but far less expensive. Used it for all my bikes starting with my 2007 Triumph Tiger 1050. Also meets Honda standard for the CB1100 stated in the service manual.

I also have been running Rotella T6 5w-40 for probably a combined 50,000 miles over my two CBs, the last one got to almost 40k before I totaled it in a little slide and it never had any problems at all. Engines running like a top.

Same here. Rotella T6 and OEM filters since oil change #2 on my CB1100. Just did my 10th oil change at 34K miles. Same with the CB750, which is still running like a top at 55K miles. I used to use the non-synth version on the 750, but oil analysis showed the synthetic held up much better in our extreme desert heat. Worth the extra few bucks. For $21 a gallon at Wally World, it's a great deal.

I run two different grades of Motul Oil in both of my CB's.
In the 2013 CB, I use Motul 4T 7100 10W40 100% Synthetic Ester, and either a Honda OEM oil filter or a K&N.
In the 2017 CB I switched to Motul 300V Factory Line Road Racing 4T 10W40 Ester Core, 100% Synthetic, and a Honda OEM Oil filter or K&N.
I have been using K&N Oil Filters since about 2003 and never had a problem with any of them on any bike.
I was using the same Motul Oil, the 4T 7100 10W40 in both bikes, but the newer Honda was making noticeable clunks occasionally. I was already using the 300V Factory Line in my Z900RS with awesome results, quiet shifting and no clunks!
So I switched the 2017 CB1100EX to the 300V last oil change. It is getting quieter each time I ride it, I change oil usually by time not miles, because riding three different bikes, it takes a while to hit some magical mile marker to change oil. So I change oil on each bike after about 3 months. A little pricey, but these are my babies and I pamper them.

Made a trip to the Honda Powersport dealership because I wanted to be sure to get the right oil for my 2013 CB1100. The guy comes back with 10W-40. I tell him it says 10W-30 in the manual. He says " I know but they are telling us to use 10W-40 now." I question him a bit further. He is adamant. I buy the 10W-40. Driving home I'm thinking "who should I be listening to, the engineers in Japan who designed this bike and fully understand the difference between 10W-30 and 10W-40, or some kid in the parts department?" Either the engineers were wrong or oil has somehow changed or...
Does anyone have any insight or opinion on this? I'm thinking it is not a big deal and don't feel like driving back to exchange the oil so I'm going ahead with the oil change, but thought I'd check in with you all anyway.
Thanks!

I know this an old thread/answer is late, but I have been changing oil in Motorcycles since 1969. I have heard the argument that engineers know all about oil, BUT they do not ride where the daytime temperatures hit 110F like they do in South Texas. So, I change weight with air temperature in my cars and in my bikes to a lesser degree. 10W30 in winter, about 3 months here, and 10W40 for the remaining 9 months of the year. I have never had an engine seize or fail, ever in my cars or motorcycles. Hope this helps.

Mike, Honda does allow for 40w, but not in the owners manual. This is in the service manual: http://cb1100forum.com/forum/showthread....#pid261600

Howdy, I did not get any info, book or manual when I bought my CB1100EX with 1200 miles on it. Heck, I did not even get a 2nd key. 10W-40 is what I ran in my last couple bikes, the 2003 Speedmaster and 1998 Suzuki 1400 Intruder. I did however, buy off ebay the 2013-2017 Honda Service Manual for all CB1100's from 2013 to 2017, models A/SA/CA/NA for about $69. It says pretty much what I have been doing all of my motorcycle life, adjust weight of oil for air temperature. USE 10W-30 from about 18F to about 70F, and 10W-40 to 110F, which is me in the Summer in South Texas. Which is shown in the link you shared.
For $69, best Service Manual I have ever bought!
I have to add I teach Physics and Chemistry, so I have a little more knowledge about the Physics of motorcycles than the average cyclist.
