if you are handy with a spanner and have a half decent socket set, I'd recommend you DIY the service. Only downfall to this is if there are any ECU updates available, you wont be getting them. However, on the whole, you could probably get 3 or more services DIY compared to a dealer. Just maek sure you stick to genuine Honda parts only. If buying on ebay, internet, etc, just make sure the parts are genuine. We are also lucky enough to have a good deal with an oil supplier thanks to Andy. 25 litre tank of oil 0w 30 for about £90 quid i think, do a search and it should come up.
