I'd highly recommend a cleaning dose of FP60 in gas, then maintenance dose thereafter and use top tier gas, like Shell. I'd also highly recommend doing two clean/rinse phases with Auto-RX & conventional oil. http://www.auto-rx.com/ http://www.lubecontrol.com/fuel.htm
I just checked on my Honda E-catalog (the same software the dealer uses) and got different numbers for the VX/CX model as compared to the rest of the models.
