Having to use it daily
#1
![Default](/forum/images/icons/icon1.gif)
I'm having to use the Jag daily and it's killing me at 17ish to the gal, as I wrote in another post about a duff 02 sensor, if that is what's causing this then fair enough but using it daily is hellish.
I also have a Golf Mk4 tdi but can't use it just now, so the quicker I can get an 02 sensor in this behemoth the better. I know it's not going to be night/day mpg being a 3.2 v8 but it will hopefully help.
Then again maybe if I get the Golf running it won't use the Jag again.
Thinking about it, I don't need a 3.2 v8 to run about it, yes I wanted back to an auto but this thing, nope.

Replacing the O2S should help. Other common cause of reduced fuel economy is a stuck-open engine coolant thermostat or a failed engine coolant temperature sensor. If the engine does not reach full operating temperature, or if the ECTS is misreporting the coolant as cold, the engine control module will continue to apply cold-start fuel enrichment even with the engine hot, leading to rich running and poor economy. If your scan tool can display Live Data, look at the coolant temperature parameter to see if it seems colder than it should.

Our member WhiteXKR has designed a kit called RealGauge that converts the "dumb" temperature gauge to show actual relative temperature. Check it out at thejagwrangler.com

Again thanks for the reply
I'll have a look at that site, I'm used to having a temp gauge though but also know they are not always accurate.
But as I said at the start, I really am thinking hard if I can justify having a 3.2 v8 tank to ideally use a daily, I know nobody here can make that decision though.

The most regrettable issue that too many of these cars suffer from is negligence by owners who don't bother to resolve simple issues like replacing faulty oxygen sensors and thermostats and other basic maintenance items, which leads to problems that are more serious and expensive, and sometimes catastrophic.
Any car you own will need an oxygen sensor or thermostat replaced from time to time.

Don

Yes you're absolutely right and I have fixed and replaced many parts of various cars like yourself and others through the years. What I simply meant was that I am trying to justify having a 3.2 v8 as a daily, i think it's just stupid especially as I only do about 10 miles a day and that's not everyday.
Sure it's nice to travel in comfort ect but it's not the be all ect, not to me. I am going to have to think about things.
cheers

When new it may have served well as a daily driver for those affluent enough to afford to have purchased it new, but I think even then most buyers used it as a luxury item rather than a commuter vehicle.
I think if you try to continue to use your vehicle as a daily driver you will find that the cost necessary on such a vehicle to simply bring it up to "daily driver" status, and the on-going cost in gasoline/petrol expenses will prove to be imprudent. Maybe it would be better to sell the vehicle to someone who wants to preserve the Jaguar as a "Sunday driver", and you maybe buy an older Fiat Panda, or a Ford Fiesta, or Vauxhall Astra as a commuter car?

I guess the plan should be to get the Golf fixed asap?

I also think I haven't said things properly too, I do like the XJ8 and have been using it and yes I would love to keep it as a second car but will need to think about that.
I also realise anything at that age will probably need some tlc unless it has been well cared for and mine hasn't, well it kind of has but not fully.
I'll see where things go from here, I also got the Golf running again and will use it as you also rightly say regarding the price of fuel in the UK, it's a rip off compared to other countries.
I would like to keep the Jag as piece of British heritage.

This I can assure you... your jag much appreciated being driven daily while the Golf was down. Jags don’t like to sit much. If you got the Golf running, kudos to you. Be appreciative that it ran for you while while you fixed the VW. I know petrol is very expensive across the pond and you probably already know about the alternative fuel conversions as well. Just remember, there’s nothing more expensive than a cheap Jaguar.
