There are also a lot of other duties on petrol and diesel that paraffin is exempt from.

However, you can use untaxed LPG perfectly legally!

True, and even though the milage is 64k I have asked the dealer to change the timing belt too.

I once had a timing belt snap on a diesel Fiesta, similar weather and time of day to my latest scenario except that it was Christmas week in the middle of Cardiff and at a very busy set of traffic lights

Damned expensive repair as I am sure many of us know, new valves etc etc, the £'s soon add up.

I'm not sure if the RAV 4 is full electric PAS or not; I would expect it to be 13 years ago.
Yes I'm having them fully check the alternator too.

Now, I fully accept the variables involved, particularly the driver, but it is well known that some manufacturers figures are far more accurate than others!

Vauxhall in particular seem to have a bad reputation for this. Our Vauxhall Corsa 1.4 rarely betters 40 MPG on the computer, which equates to about 37 MPG if you calculate actual fuel used and allow for milometer inaccuracies.

To be fair it will manage around 48 MPG on a very, very long run, and with careful driving, but this is still nowhere near the 60.5 MPG claimed for extra-urban driving.

Meanwhile, the same driver (me) consistently manages a recorded 60 MPG or better in his 'gas-guzzling' 3 Litre Jag, even though the true figure is closer to 55 MPG, which is still better than claimed by JLR if I recall.

Coming back to my question of Petrochemist about fuels and additives:

Our old Mk V 1.6 Astra was supposed to do 45 MPG. The only time we have ever seen that was over a long journey using Shell regular unleaded with Redex added to the tank. Without the Redex it would do about 41 MPG. I have occasionally tried it with V-Power unleased, but it runs like a three legged camel every time!

The Corsa engine would seem to be almost identical apart from its slightly smaller capacity, yet it runs much better and smoother on V-Power than regular unleaded, and even manages an extra 2 or 3 MPG. However, Redex makes no noticeable difference.
The test cycles are designed to simulate a "typical" - idealized, if you like - urban drive, an extra-urban drive, and then there is the combination, which, IIRC, is a simulated combination. They originally came out of developing for USA EPA and Californian EPA requirements. Sure they have been modified over the years, but they aren't much like a real driving situation. Just as an example, there are one or two full throttle accelerations in the urban cycle; where can you do that for real these days? The industry has never regarded or presented them as truly representative of 'real' conditions, because they aren't. And, as I remember, even the government says they are to allow the customer to compare vehicles.

Another point is that test fuel of precisely known quality is used for the test cycles (in order to accurately measure emissions), but who out there uses test fuel for real driving?

Cars are not like aeroplanes: fuel for the latter can be precisely quantified given load, wind, speed, etc. You can drive exactly the same route two or three times and get different results each time. The only accurate measure of fuel consumption is by weight of fuel consumed, not volume. Fuel density varies greatly with temperature, and that variable alone causes big changes to apparent consumption.

Temperature gauges, like fuel gauges, don't give an accurate measure anyway. Accurate water temperature (along with fuel temperature, mass air temperature, air density or equivalent, etc) are all fed into the engine ECM and made proper use of. When you think the temperature gauge is reading a little higher than usual, what are you going to do with the information?

True Keith, but then it's been a Toyota main dealer that has maintained the car since new.

I am perfectly happy to work on most cars but there is little pleasure in it these days, and the manufacturers like to make it difficult by using oddball fasteners in special sizes that make them difficult to remove.

As far as insurance is concerned there is no legal reason not to work on these things as long as you are 'a competent person'. Believe it or not, that even includes gas work in your own home provided you are not a Landlord and are not charging for the work, although I wouldn't recommend it.
Define a competent person.

Come on Keith, I'm not suggesting carrying out work that would be safety critical, it would be foolish to do so if you do not have the skills or knowledge and I have after all had the dealer to do all work when needed. But basic routine maintenance used to be easy to do, not any longer.

I had a Toyota Carina E 2.0 Exec some years ago, and that went to the main dealer that I bought it from. It didn't let me down, but that dealer was always trying to find ways to wangle more money out of me - like claiming, supported by a 'computer printout' that the spare tyre had worn by over 2 mm between services - and it hadn't been anywhere near the road! That dealer actually went bankrupt at a later date, and closed down.

The problem is that modern cars are so reliable that dealers don't make enough profit from repairs (even though main dealers these days charge over £100 per hour); so most have their pet ways of trying to get more money out of customers, including charging for work that has not been done. An example: after the Carina, I bought a Citroen BX, which proved to have an apparent clutch problem. The garage I bought it from sent it to a Citroen dealer for the warranty work. The latter claimed they had taken the clutch out, and there was 'nothing wrong with it'. They couldn't have, because, (a) it's an 8 hour job, and the car wasn't there that long, and (b) the paint seals on the clutch housing were intact. The problem turned out eventually to be a kinked clutch cable, BTW.

You aren't necessarily going to know what is rated safety critical or not. Routine maintenance is possible: oil and filter change, aircon filter change, checking brake pads, fluid levels, bulbs, battery condition (unless sealed), if you have a system checker (or even without) you can check for fault codes. Apart from visual inspections, there aren't really that many more things that the garage will do.

Would you change brake pads, for instance? And if you did, would you check disc thickness? A lot of people do change brake pads, but I doubt any check discs! And how many people would bother to change the fluid at the recommended intervals?

Very true, then again most dealers reckon they don't make much money on new car sales either. So where do they make their money from?

(In the past I did; but it's now illegal to do electrics in the bathroom where it may come into contact with water, if you aren't a qualified electrician. And all work has to be certified.)
