Title: Another MPG Question!!!
Post by: Psychoca on 15 November 2011, 19:48:39
I know, looking at yet another topic covering MPG...  In a chipped 2.5 TD manual...

Through the many posts that I have read surround MPG, I feel that I have a high consumption...  I get in general around 32MPG, regardless of how I drive, which fuel I put in, even immediately after filter changes...

As I don't believe it to be fuel related, the only thing I can do is check the air intakes and ensure that all is as clear as it should be and possible drop the intercooler and give that a clean too...

Any other ideas would be greatly appreciated...

Thanks...

Sounds a bit poor if its a manual

Your quoted 32 mpg is about right for a chipped TD ;)

The TDs that I maintain, (one's chipped, the other ain't!), actually return 33 mpg constantly when used locally here in The Valleys. (imagine the terrain!).
So you've nowt to concern yourself with IMO - remember, you've got a near 2-ton car here!

Here's my proven fuel consumption figures:
Locally: 33 mpg
Spirited cross-country driving: 40 mpg
Steady motorway 70 mph cruising: 44 mpg

All things considered, I'm quite happy with those figures! :y

Fair enough, just keep seeing the high (high 30's) mpg's that get quoted about from time to time and just makes me wonder how some get their numbers...

sorry missed the manual bit!  :-[

Should, surely get near 50mpg with a manual tractor?

I reckon I could nudge 35/40 mpg sitting at 65/70 in the 3.2

Had a quick look at the intercooler and without a doubt, the fan is siezed solid, so, going to pull that off to see if that makes a diiference...

I got 34.9 in my 3.0 auto sat at 80, I reckon I could easily get that if I was only going 65/70

The 3.2 (at least base don what several have said here) seems markedly worse on consumption ;) The best I ever got was 28/29mpg sat at 75mph for an entire tank full..

I must be doing something badly wrong, I get about 28 mpg at 70ish mph in my 2.6

I got 28.9 with cruise set at 85 mph  :)

30+ would be easily achievable sub 70 i think

Chipped manual tractor, 32 sounds low. I used to get that from chipped auto tractor, which was always ragged.

STandard 3.2 Elite, best I ever managed over a tank was 30mpg, which was a (mostly) 80mph cruise back from Wales, until the red mist descended ::)

I mean, you're already doing 80...

Drive 2.2 petrol and traveled from Bristol to Liverpool  over the weekend got 35.9mpg according to the display averaging 80 mph well chuffed 2.2s not renowned for being fuel efficient but was please with it's return.

Get 23 local, just about 30 on a long run( Elite). Which is a major disappointment after constant 35's from the 24v Carlton I had, trashing the guts out of it constantly, that's progress for ya  :y

Post by: albitz on 16 November 2011, 21:52:36
Same figures as I get from my 2.5, which is worse than my 24v Senny used to do.And it was driven a lot harder. As you say - progress. ::)

I always found my 2.5 to be quite thirsty,the Merc I run now is quite a bit better on fuel  :y

How much did the Senator weigh?

To be honest, I reckon all the green do-gooder shite fitted to modern engines hurts MPG.  Certainly, without any shadow of a doubt, the 2.6/3.2 aren't as economical as 2.5/3.0

Another factor is, even 10yrs ago, the trunk roads were empty, allowing decent cruise MPG. Howadays every cock sits in outside lane going slow.
Title: Re: Another MPG Question!!!
Post by: albitz on 17 November 2011, 18:21:17
Pretty sure the Senator was similar weight to an Omega.May have even been a bit heavier as it was bigger.Traffic levels were bad 10 years ago.Now however,they are appalling,could be a factor. :y
Straight six was also a far better engine though. :y ;D

I had a feeling the Senator was lighter. Didn't have to lug about all the saftey shite.

We'll never agree on which engine was 'best' (best for what though?) :y

Best for everything. :P ;D............must do a bit of research on Senator weight,Im curious now. :-\
Wouldnt want to try and bore a V6 out to 3.6 and put a couple of turbos on it. ;)

Somewhat lighter.
According to Mr Haynes :- kerb weight of a 2.5 man was 1445kg & a proper 3.0 24v with a/c was 1575kg  :y :y :y

If you've ever removed a front seat from an Elite you'll know how heavy they are.  :o

The do-gooders have ruined that sort of inovation  >:(

Probably the do-gooders were the reason for the lack of v8 Miggy, as the official excuse seems poor.

1575kg is a bit lighter,but not really enough to notice I wouldnt have thought. Talking of heavy seats,CD spec drivers seat isnt exactly light.I fell over backwards while carrying one a year or so ago.It land on top of me and cracked a rib. ::) ;D

Just to get back on subject, spoil-sport I know, doesn't help that the poxy auto box is forever swapping cogs! The 5 speed in the Carlton could go from 17-18mph to 120 in top without thinking about it, just a brilliant pairing and made auto irrelevent! ;D

i am currently doing my own little ECO/MPG test.

mine's a petrol 2.5v6 CD. filled up from almost empty (the trip comp. flashing telling me i only  had 26 miles left on the fuel in the tank and gauge on bottom red rung)

filled up tut max and cost £78.97 yesterday.

i immediately reset the dash to 0. and am going to see, with careful drivin (and i mean not exceeding 2ooorpm) how many miles i can get out of it.

trip computer not filling me with joy..... full tank it reckons will give me 272 miles. with a 16.5 gallon tank that equates to 16mpg  :o :o :o :o

now i must stress that i'm purposely only doing town/urban driving for this real world test............ i know from doing long trips that the old girl actually works out pretty economical when sat on a motorway for 12 billion hours  :)

ill post results when empty if anyones interested!!!  :y :y :y :y :y
