At what point is it no longer worth it?

if it works for you guys,THAT IS THE MOST IMPORTANT,
now this can be done to a modern piezo system,, one small button close to or on steering wheel,lets call it PUSH-TO-PASS button.
it would increase torque to around 450-500lbs.ft. HP up around 30% higher.
all that would be required, is a modified ECU, all stock tuning under all driving conditions(to clear MOT), but on hiway,or away from a standstill, push for much increase in power.
you know!! that sounds like a GOOD idea, would anyone be interested in such a device??
and could be tested with and without DPF and catylitic, for potential results.
and giving it some thought, it may require a bigger turbo, time will tell.
in Texas, we have at least two 1000mile interstate hiways, with almost nothing on them, one east to west,, other south to north. miles and miles of smiles.
and for some interesting stuff , Google TEXAS MILE
THX for your interest,, RON

Derdave,, in USA, there are some Chevy-GMC duramax diesels runnin a blend of 50-50%
used cookin oil and diesel ffuel with no bad effects, and they are hi-pressure PIEZO injector systems.
im betting that Jag 2.7D would handle a blend of fuels, course someone would have to step up and try it!!
its all about good maintinence and proper setup.

Caution:
• Do not use RME (bio diesel) except
in the case of those proprietary
diesel fuels which contain a mix of
up to 5%. Jaguar can accept no
responsibility for damage caused
by using RME in concentrations
greater than 5%.
• Do not use vegetable oil instead of
diesel. Jaguar can accept no
responsibility for damage caused
by using vegetable oil at any
concentration.

if you go EXACTLY by the book , what can one expect,OUT OF LIFE.
that is what we expect from the slave population!
all diesel engine manufactures say do not use anything other than recomended fuels!
actually there are a few veggie oil car clubs in UK, with some very good results.
chip burners,ETC. and the smell is more plesaent than diesel oder.

But would never use it at any ratio in the Jag or heard of anyone who has.

This is the sort of reasoning that car dealers don't want you to do :-).
I penciled out what it would cost me to use my XJR for occasional pleasure use and buy something more economical for daily use.
XJR/baseline
2000 miles/month @ 18mpg average= 111 gallons. 111 gallons x $3.75/gallon = $416/month in gasoline expense.
What if I bought a economy car for daily use and drove the Jag only on weekends?
Decent used economy car, 28 mpg average:
$5000 purchase price + $500 for typical after-purchase used car fix-its = $5500
1800 miles @ 28mpg average = 64 gallons @ $3.50/gallon (regular fuel) = $224/month in gasoline expense.
200 miles @ 18 mpg (Jag/weekends) = 11 gallons @ $3.75 = $41/month
$41 + $224 = $265/month gasoline expense.
$416 - $265 = $151/month in gasoline savings
Cost for minimal insurance on a second car = $50/month
$151 (gas savings) - $50 (insurance) = $101/month net savings
$5500 (purchase price)/$101 month (savings) = 54 months to break even :-)
Of course all of the above is predicated on *keeping* rather than *replacing* my Jaguar. I simply cannot be without a Jaguar. It won't happen!
One alternative would be to buy a more modern Jaguar that would give better fuel economy, thus allowing me to run just one car. Perhaps I'll browse the S-type section and see what kind of fuel economy I might expect.
