If it is an i-DSi, remember they have 8 plugs, with four at the rear of the engine.

I must have picked up on your statement,

"At normal motorway speeds the engine has to do a lot of work and that means it has to consume a lot of fuel."

Which I do not agree with.

We all use cars, they use fuel, how much only matters to the driver, or not in my case. As long as my car is in the ballpark for normal use I am happy, if not I will get it fixed. To date my car has varied between 37 mpg and 45 mpg depending on use. I have not done a long journey yet but will be doing an 800 mile round trip in a couple of weeks that will give an indication of motorway consumption.
Honda Jazz Mk3 2015 - / Priority Phone Bluetooth Connection

I wonder if there are any whizz kids out there?

I have a new Jazz with the Infotainment system without buttons (just a touchscreen)

I have paired both my phone and my wife's phone. However, I have to remember to connect to my phone when I use the car.

I was looking for a setting that would allow me to set my phone as the priority phone, so if both our phones are in the car it would connect to mine, but when my wife is in the car alone it would not find my phone and would connect to hers.

I can't seem to find a way to do this, it seems very limiting if I have to remember to set the phone to mine manually every time we are both in the car.

According to the Haynes manual the Manual Transmission needs an oil change every 48,000 miles or 4 years, the handbook I got with the car says 75,000 miles or 6 years (Except EU), and the service book that came with the car (the one with the dealer stamps in it) says 75,000 miles or 8 years. It says the same for AT, so as I assume that is the i-shift, as it also gives numbers for the CVT.

I disagree. An engine is lightly loaded cruising at motorway speeds. It is acceleration, shifting a lump of metal and its contents up to speed that uses fuel. My MT 1.3 engine ran at about 2,500 revs at 60 mph and 3,000 revs at 70 mph. My 1.5 CVT engine runs at about 2,000 revs at 60 mph and 2,500 revs at 70 mph although this varies with gradient.. Cars use less fuel on motorways because there is no acceleration from a standstill and the engine is lightly loaded.
They use less than they would around town, true. However drag squares as speed doubles so there is roughly 30% more drag at 70mph than at 60mph. At 80mph the car is having to fight 60% more drag than it would at 60mph. And at least at 60mph the Jazz can operate its engine in the efficient Atkinson cycle mode.

So assuming the engine I using almost 100% of its power to cruise at 110 mph (which it can) what proportion of its power will it be using cruising at 60 mph? Would it be relatively lightly loaded at this speed or even 70 mph compared to 110 mph or accelerating from 0 to 60 on a wide open throttle?

You have to think about an engines capabilities, not how people use it. Most drivers never heavily load their engine even though it is designed to withstand it.
I think you're over complicating this and possibly just failed to understand my original post. A summary of what I wrote was that in order of 'least fuel consumed per mile' travelled we have:

* Steady 60mph.
* Steady 70mph.
* Urban driving.

You're not going to find anyone that would disagree with that statement. The extent to which those three differ in 'fuel consumed per mile driven' will vary by vehicle but very few vehicles (probably none at all) will break that pattern. I honestly don't know why you're trying to argue with me because you seem to have made up something to object to that I never posted.

At no point have I suggested that motorway driving at any steady normal speed is less efficient than urban driving. All I've ever said is that 70mph uses more fuel than 60mph.

Easy job to do but my Dealer in Plymouth said the oil needed changing 10 yrs???? ten thousand miles??? and to use MTF Fluid only NOT ATF you could do it yourself as to any sensor  never heard of it the awkward thing id the main drain plug  you will need a long wrench to shift it, take out the top filler plug first easy to do

Yes One owner a young lady I spoke to her and asked about the car it was her shopping trolley from day one, the car has just been serviced at non Honda garage new pads all round, all oils been changed only last month. 
Given its age (not going on mileage) I will be changing the plugs
 Just washed and clayed then Boora polish next wash will be followed by Boora sealant.

My 1.5 uses a little more fuel than my 1.3 did but it is worth every penny!

I second that, I love the extra power of the 1.5 engine for filtering into traffic lanes on the motorway and pulling away on roundabouts. Not as economical as the 1.3 but pretty good for a petrol engine.

As far as I am aware, the i-shift gearbox is exactly the same as my manual box, except for automatic electrical actuation, and an oil change is no more difficult than a standard gearbox oil change.
