Use full synthetic 10w30 weight.
2.6 if you are just replacing the old oil 3 to 3.5 if you have just rebuilt the engine
If you mean a different weight then you're not very wise. Use the exact weight oil that Honda recommends. If you are referring to the brand of oil, you do not have to use Honda oil. In fact Honda does not even make oil their oil is refined by another company. You can use any major brand oil of your choice, as long as it is the correct weight.
30 Weight Non-detergent Oil
you can use standard ATV oil from places like tractor supply. or you could use a 30 weight oil
5wt oil. Use Honda oil.
10w30 weight any major brand.
The type of oil grade to use on a VT1100 Honda shadow is 10w 40. There are several brands available that carry this weight and the best choice depends on the riders choices themselves.
Any name brand 5w30 weight oil and a quality filter such as Wix or Purolator. I use Pennzoil oil and Purolator filter.
Most use any 10w30 weight oil. You can also use 5w30 either will do the job.Hope this helps. Michael
5w-30
10w
Any JASO-MA or MA2 approved oil of weight 10-40 W or 15-40 W will do.
