Engine Oil - Castrol 5W-40 Edge Diesel or any quality 5W-30 or 10W-40
Oil FIlter- Genuine Honda
Gearbox oil - Honda MTF
Diff Oil - Castrol Syntrax 75W-90 (I think thats the weight)
Airfilter - Is is dirty?
Plugs - NGK (PFR7G-11) or Denso (PK22PR-L11).
Coolant is only every 7 years in my service manual - you can do it if you want though.
Plugs the same. Just inspect them
