Well I'm pretty sure my mpg reflects my lead foot as well as the Range Rover I have a 300C getting about 15mpg on LPG.
If it isn't a silly question considering the amount of Detroit Iron you have, is that a Chrysler or Nissan 300C? If it's the Nissan and you're only getting 15mpg out of it, you need much lighter wellies!
If it's the Chrysler 300C, they're also a big V8 if memory serves (last one i had anything to do with had a diseasel lump in it but the owners saving grace was they also had a V10 Crossfire.........
) so probably about right.
At least we'll knot argue about a mile being a bit longer over the sea
In a lot of US cars for the European market, such as my old 2001 Grand Voyager, you can select either US or metric measurements.. but in my car the one setting controls both the fuel computer and the climate control / temperature readings and I'm not sure if the mpg reading actually is US (like the computer says) or Imperial (modded for UK market, save the computer still reading US). In the UK we all use mpg rather than L/100Km but the younger generations use degC rather than degF, so neither setting is ideal for them.. Even if I preferred degC over degF, because I am vastly less familiar with L/100km than I am with mpg I would still set the computer to US. The girlfriend is a bit younger than me and in this hot weather when I've pointed out the high 80's readings she's asked what that is in 'real temps' i.e degC... Easier and quicker to do the conversion maths in head rather than switch the computer between US and metric while driving but having only the one setting could be considered a bit of a negative by younger UK users... not that they'd buy a Grand Voyager!
Dad reckoned teachers back in the late 50's didn't always seem qualified and some probably weren't
. Brought back memories of the next door neighbour when I was a kid, previously a WW2 bomber pilot he taught my dad at school (qualified?) and still smoked what was probably the same pipe he smoked in class. Apparently he regularly dished out punishment to dad and his mates but they were on good terms as neighbours, dad reckoned he deserved what he got at school
Agreed with your range guestimating method. Installers are always being asked how much range a particular tank will give, it's best to turn the question around and ask how many mpg the owner gets on petrol and calculate from there.
I find the easiest way of converting degF to deg C is to work from 82F/28C. If converting 20C to Fahrenheit, the difference would be 8C so double it, take 10% off then subtract that figure from 82F. In other words the start point is 28C, subtract 20C to get the difference 8C as already mentioned, double it to 16C, take off 10% which is roughly 2 (1.6 but let's "knot" argue) and it becomes 14 - subtract that from 82F and it's 68F (or 68.4 if you want that decimal point back!). While it may not be 100% accurate, it's a very close ready reckoner without going into the add/subtract 32 and multiply/divide by 9/5 as i was also taught at school.
May not work for everyone but works for me.
The range guestimate method was the way i would do it, seems the most logical. Still reckon he needs lighter wellies though!
