91 minimum.
87 octane would be the minimum but 91 would be more ideal.
I had an 1986 Honda shadow VT1100 (loved it) and I ran mid grade with no problems. You can run 87 octane with no problems.
I would use 91 octane gas. That is what I used in my Honda Elite 150.
regular... octane 87
Regular should work just fine. If you hear it knock a little, then use super.
87 octane
answer 87 octane
87 octane
87 octane unleaded. There is no benefit to running higher octane fuel in the VLX. The only caution is fuel with a heavy ethanol content as the ethanol can attract water when sitting for a while which will cause problems with the carburetor. (Personal experience.)
87 octane regular
The gas octane that would be the best in a Honda CR-V from 2009 is 87 octane. Higher octane gas will improve its performance, but it is only necessary to have 87.
