1) Ive been searching for a set of OE tires but so far had no joy unfortunately. That said I took off all the wheels to give them a good clean tonight and all the tires have loads of tread left so I wont be throwing them away just yet. I set the pressures to 38psi all round too. Im not really into squeezing every possible mpg out of it, I do value grip and safety too. All were between 25 and 30 when I checked them though so even that will make an improvement.
2) Car was serviced at Honda just over 1k miles ago including all filters etc. Ive bought a job lot of oil filters and oil as well though so I can do interim changes myself. Ive still got a 25 ltr container of MTF too from Hondas of old to slowly work my way through.
3) Will read up on the earth strap thing. Car seems to run ok so doubt it will have any codes, will have a check anyway though.
3.5) Rear brakes are spot on
4) Have new cluster, but as yet my manual has not arrived. Should be here Monday hopefully.
5) Ive got at least a couple of months to make some blanks up surely?!
6) Have a ramp booked next week so will do that then.
7) Already becoming an mpg nerd!! Ive taken the majority of honda people I know out in it today and there has not been one who was not seriously impressed. In all honesty though I think I'll just drive it as a normal car and not have to worry about chasing that extra 10mpg. Im more than happy getting 60 odd.

Been playing with the lean burn thing. Think Ive sussed it but the roads and too rolly around here to stay in it for more than 10 seconds. It seems as soon as it goes in I either loose speed fast, or there is another hill in the way!!
9) More like fill up once a week as opposed to every other day!!
