It’s somewhat annoying that LPG has not gone down at all, despite crude oil prices dropping through the floor. Talk about the biggest con! I assume it’s the same aroumd your way. Most Places up here are still charging 62-70p/L!

Mixed driving should always generally give 20+ mpg, especially with us gallons. If it doesn't - something is not right. Main culprits would be old o2 sensor, leaky injectors, tps not correctly setup, air leaks, fuel pressure regulator, etc, etc.

Well no US gallons here, we use real gallons but have more traffic lights than you can shake a stick at - I have to negotiate about a dozen intersections every few hundred yards on a cold engine before I get out of town and that does not help with the overall consumption.

Things that have been replaced :
o2 sensor
Maf
ICV
injectors
TPS calibrated
No air leaks
FPR.
Temp sensor
All other sensors etc
Air Filter
Intake cleaned out every spring.

I do drive rather "spiritedly" and tend to boot it at traffic lights :lol: but on a long run can get 12-13l/100k.

Keep in mind the Canadian cars are fitted with EGR and air pumps and I believe slightly lower compression than UK cars - plus I run regular gas not premium (and have for several years with no ill effects).



The only things that haven't been changed are the ECU and the catalytic converters, but I'm not short on power so it would take a lot of aggro to get me under there eff'ing around with exhaust clamps etc.

Main thing is, I really don't care about the MPG, it's just the cost of owning an XJ40 as a daily.

That’s a good point on the EGR/ emissions stuff. They do sap power, which means you have to push the pedal harder.
Can you get away with ditching it, or is that a big no no?
People in the U.K. (especially with Land Rovers) seem quite keen on EGR blanking/ delete over here.

Luckily I have an LPG station, 3 minutes from home and they have it for 55.9p for the past 2 years I think now.

That’s good going relatively, but the whole point with it, is it supposed to be priced in line with petrol prices. So it should have gone down, but of course hasn’t. Just watch though, they will happily put it up.
I was considering another Lpg vehicle, but I have held off for now.

I suppose I could plug the throttle body inlet and blank off the valve but to be honest, after all this time I don't feel motivated to potch about with the car ..she's running fine, starts right up and never lets me down.

What more can you ask of a 26 year old daily?

I feel compelled to make note that my 92 passed 182000 miles yesterday on a 100 mile round trip to the "nearest" jag dealer to get wheel seals for the XJS while Cruising at a Leisurely 75mph. Wife was with me though so I was not allowed to get a pic (as I have been trying to do). That car always makes me smirk. Even more so becasue of the mileage and the ease that it passes the miles Most Of The Time. The last time I checked fuel consumption on it, it was getting 23-25 which I am happy with.
