Title: 2.3 16 v Economy?
Post by Phil_Waller on Oct 17th, 2004, 6:19pm
Hello

Could anyone else on here please let me know what kind of economy you get from your 2.3 16v? Automatic.

Whilst I am very pleased with the car I am not sure if the economy is right.. I have done 100 miles today on A roads 50-60 then a couple of motorway stints 70-80 mph.. Two adults the correct tyre pressures and the gearbox in E and the overdrive left on.

The trip computer says I averaged 30.1 mpg..

Is that right??

The OHB says 19.3 for symulated urban and 33.6 for outside city limits.. total 26.7

The car drives perfectly and Eric slapped the OBC diagnostics on it the other week with no faults found..

Just curious.

hi phil

that sounds about right. i've never got what you would call great mpg out of mine. best i've had is 28.3 @ 70mph (81mph on dash) on the way back up from derby. not too bad on lpg ;D, but not the 33/35mpg that is claimed. :(

Ok mate thanks for the update..


I found myself driving it back home like a fairy. I got rid of my 24v because of that reason. I know what the economy on the 24v was like and it was worse so I suppose with these big cars comes the cost and fact that they are big and even with the 2.0i the petrol is drunk...

hi phil

know what you're saying. i took the car down to devon last year via london and the derby meeting. don't have exact figures but it cost something like £250 :o for the round trip. i nearly got rid of it because it was costing so much. that's when i remembered about lpg. costs a bit for a good system, but pays you back big time. 19mpg around town = 38 mpg ( 37.9p to 42.9p per litre), same as a small car. something to think about. ;) http://www.fordscorpio.co.uk/lpg-conversion-23.htm

Hi Phil
I toured cornwall for 2 weeks in September with mi 2.3 16v manual

1800 miles
computer said average 36 mpg
wallet seemed to agree
I changed from  MK3 2.9i and really notice the difference in economy especially round town
hope this helps

I only get 21/22 MPG. That's 2/3 motorway/dual carriage, rural roads and the rest is city traffic, quite often of the gridlocked fashion! I am usually fairly light with the foot on the throttle unless I want to get ahead of someone at the lights  8)

Hi Phil,

I agree that your consumption seems about right. When I picked up my 2.3 and drove it home about 60 miles, I was horrified at the consumption. Made my old 2.0 carlton estate seem very economical. I have given up with the MPG being displayed on the dash as it makes me too depressed. I just watch the temp instead. Economical, Scorpio's are not! Still a great drive though.

I'm getting low 20's for town driving and up to 29 mpg for motorway for my 2.3. Gonna try cleaning the MAF to see if I can crack the 30 mpg barrier! It has done 202k miles so the motors probably a bit tired now. My mate has had 31 mpg recorded on his 2.9 cossie but that's with a lot of motorway cruising at a steady 70mph.

Title: Re: 2.3 16 v Economy?
Post by Phil_Waller on Oct 18th, 2004, 10:21am
Thanks gang!

Was a little concerned as I am still new with it. I think constant 70 it does about 35 mpg so it ties in with what you guys say.

I am looking at LPG conversion for this car as i think it will be worth it.

This still bothers me and I am wondering if my choice of engine was premature..............................

I should know as I had a Granada with a BOA 24v.. What are the Scorpios with the BOB like on consumption?

Title: Re: 2.3 16 v Economy?
Post by scorpio_man on Dec 17th, 2004, 5:14pm
hi phil

no, i don't think you were. too many scary stories about the 24valve, imho. the 2.3 is a cossie anyway. look at the sierra. how many 2.0 engine went bang? now i know member are on here mainly because of problem. but when you hear £800 just for the bits :o well scary!
go for the conversion. about £1600-£1800. gas and the gov bit is still the same....37p-42p. give http://www.autogas2000.co.uk a phone (leeds). ask for chris (owner), tell him you got his number from the ford scorpio site.

regards

still getting 19mpg @ 20mph around town = 38mpg. that's takes some beating even in the 2.5 tdi! ;D

Hello,
I have a 2.3 Estate. I drove up to the Midlands from Norfolk last weekend. I averaged 33 to the gallon on the round trip of about 350/400 miles. I use cruise control as much as possible. It doesn't seem to use much more fuel by driving quickly. Just uses a lot all the time !!
I generally average just under 30 mpg driving about on the country lanes of Norfolk. No motorways !
I have saved on fuel since the air con compressor gave up.

I seem to average about 23mpg long term with my 24v and a lot of that is the 5 mile run to the supermarket. I'll admit to driving the 0.7 miles to work about once a week too!

A long motorway run sees around 29mpg so not too bad.

It's a different story if you get stuck in traffic a lot though.

Post by JohnJ on Dec 21st, 2004, 8:42am
Just done 110miles last sunday and averaged 33mpg...used cruise most of the time and when the car tries to go up a steep hill i turn it off because it tries to go up it in second gear, it will do anything to keep the same speed.
But at the end of the day my mate gets 55mpg aout of a Passat and he gets that all day every day. and then teases me about it. ::)

John is yours auto? If so then that seems to be how it should be.

I put this post up in the Galaxy forum the results are interesting...

It kind of concludes that if there are no major faults in the engine management system then that is how the cookie crumbles with these engines!

Hi Phil,

I have been keeping an eye on the fuel consumption over the last couple of weeks and I havn't even got into the 20's yet. In fact I havn't got into the 20's since I bought it!!!
It still averages around 17. This is virtualy all urban at the moment. Did all the usual stuff when I bought it (MAF cleaning and OBD check-no faults). Lovely engine, just too thirsty. I really don't think it is much better than a 24V. At least you get performance with the 24V.

Ah well, better put in a bid for that full petrol tanker on e-bay ;D

Title: Re: 2.3 16 v Economy?
Post by scorpio_man on Jan 7th, 2005, 11:41am
hi there

when you did the obd scan, did you check the long term fuel trims etc? 17 seems a bit low to me. before i got my conversion, mines was 19mpg. have you checked out all the usual bits? fuel cut off loom, brakes, autobox fluid colour etc. one think i have noticed and i think this applies to all engines, is that it seems to use more fuel if you gently accelerate to a cruising speed. better to get to the cruising speed as quick as possible, imo.

btw, when did you last have the a/c serviced? if it's low on gas/oil, then that will increase your consumption.

Title: Re: 2.3 16 v Economy?
Post by TaperOne on Jan 7th, 2005, 12:28pm
Hi Scorpio,

Checked pretty much everything you mention. Air Con may need a charge but works pretty well, I tend to leave the CC in auto mode all the time. The thing is it drives realy well. No misfires, no rough idling, gearbox changes well-just thirsty. The best I have seeen so far is 18.5, and that was after some very 'nimble' (boring)driving. With regads to the long term fuel trims, the OBD checker I used cannot diagnose that far. I used the Sykes + P hand held from my mates garage which takes different modules for each vehicle and only allows reading and clearing of fault codes. Think I will invest in OBD lead and hook up to the Laptop. Might see a bit more info that way.

You need the PWM lead.

You get a lead and a code to use the software from there ;D

Got mine within a week :o

Post by Eric_R on Jan 10th, 2005, 7:54pm
Phil,
I think 30mpg is good for a big saloon with a 2.3 engine.

In fact, the balance shafts on the 2.3 were actually designed by Cosworth, so in a way you have a Cosworth too.

The best I ever get is 26 mpg on my 24v - and that's on a run. I never look at it on urban.   :o

Give me a ring and we'll check out your OBD again.

Incidentally, in 1924 the Ford Model T returned an average of 24 miles per American gallon.

So 30ish per english gallon.

Yes.

which lead? there was about 3 that were PWM also i need a USB plug as my laptop does not have the sockets that they show.
also because it's a US site it does not list the scorpio.
i seem to have downloaded the software ok but does the code come with the lead when you buy them?
would be grateful for more details on this.

Yeah, we did too. My old 2.9 12v K-plater got 33+ MPG on most runs. The 2.3 16v does around 26/27mpg.

the sian half of Sian_RK here, the one who drives the car all the time. :)  it is a 2.3 ultima, with auto, and is the '98 facelift model.

i get a consistant 25.8 (average, displayed) on my usual drive on scottish A/B roads (driving around 50-65 mph, with lots of slow corners and ludicrously rapid overtaking).  if i reset it before a nice fast, steady drive, i can get it as high as 32 (average, displayed).  it does best at a very consistant 70-80mph, and is totally apalling at lower speeds.  it displays enormous variation if i check the instant display, so i don't bother.

Cool, obviously cleaning your carb worked ;) Thats it, mines out for the Dremmel treatment later in the week ::)

Just checked the fule figures on my 2.0, 3000miles 23mpg, did have a broken IAT for most of that though so I'm expecting an improvement meself :o

Ps. looking like your missfire is electrical :-/

Title: Re: 2.3 16 v Economy?
Post by Eric_R on Jan 17th, 2005, 4:55pm
Guys,
What a very nice car Phil has there - good unmarked paintwork and an excellent metallic colour, too.  IMHO a very good buy - and I do like the 2.3 engine.

We checked out the OBD and found no diagnostric trouble codes at all. The engine bay is very clean and the engine runs very sweetly.  HO2S11 shows a good switching and the HO2S12 shows a steady line, indicating a very healthy catalyst. There is a 4% negative fuel trim, but this shows a very slightly rich fuelling rather than any air leak and may have been because the engine was not at full op temp, but we'll keep an eye on that.

However, I agree that there's a very slight misfire that Phil mentions. It was occasional and not serious, but knowing Phil he'll work at it until it's cured,  :D

We discussed some options. The EGR pipe is hot and solid and no sign of leaks, while the FCO wiring inside the plastic box over the fuel rail looks okay, but we ran out of daylight and didn't look under the cam cover.

A less fastidious owner might not even have noticed the miss and the Diagnostics shows no concern for it, so it is not endangering the catalyst.  Phil has changed the spark plugs recently and believes they are okay so we should be able to rule them out.  This still leaves the Fuel Cut Off Loom or the spark modules under the cam cover.  However, we ran a datalog on the MAF and other items and I'll compare these with other readings I have of 2.3 diagnostics and see if there are other anomolies.  After our fiddling the misfire at idle stopped altogether, so next time we'll check out the FCO loom thoroughly.

Very fine example of a 2.3 Ultima, Phil.   ;D

Post by Phil_Waller on Jan 18th, 2005, 7:10pm
Thanks for the compliments Eric..

Yes I am not going to rest (as long as it isnt a false economy) and get this sorted.

When I get paid I will be getting a new loom.

What about the fuel regulator? You mentioned?

Title: Re: 2.3 16 v Economy?
Post by Eric_R on Jan 21st, 2005, 4:18pm
Phil,
The 4% negative fuel trim at idle is well within the normal parameters for the adaptive strategy, so I don't think the fuel regulator would need changing - unless the FT goes much more negative. I mentioned it because a fault with this could cause the HO2S sensor to stop switching, but there's no sign of that on your car.

A negative FT also usually means that there are no air leaks to contend with.

A new Fuel Cutoff Loom must be favourite to fit first, especially if you remember that the engine stopped the slight misfire after we had fiddled with the FCO - a very good hint there, IMV.

Post by Phil_Waller on Jan 22nd, 2005, 12:09am

As you know I have purchased the loom and the regulator. As disscussed I will change the loom first then the regulator..

I have achieved an average of 33.5 MPG today 384 motorway miles 70-80 mph..

I think that is as good as it gets and I am well pleased.. Still havent fitted the loom yet plus I might have a slight exhaust leak...

hi phil

33.5mpg. that's not bad at all. best i've seen was 28.6mpg coming back from derby last year. do you think cleaning the throttle body has helped this? haven't tried car on a run since part cleaning mine, so don't know what difference it makes.


oh, did you reset the trip computer?
