Hi all I've been offered a 2.5 diesel for a straight swap for my MV6 2.6 am I doing the right thing if I swap as I'm looking to lesson my monthly outgoings ie fuel + ins cheers in advance

[0795omega]

i had a diesel one once,didnt think it much better on mpg to be honest,and certainly not as quick,but your choice bud!

[Shackeng]

My chipped TD Auto only does about 25 on local runs, 33 on motorway journeys. Manuals are much better on fuel, just a pita to have to drive.

Test drive it first, then your mind will be made up for you.

Currently run one, and can't wait to get my V6 going again - as most OOFers can testify to, as I mention it in every other post 

Ok, for me I'd say good and bad...

V6
-Romance "I have a V6 quad cam 24v, don't you know"
-Throaty burble or sewing machine hum when you want it.
-Acceleration. mmmmm
-Actually decent mpg for what is it - partially as Vx deliberately made this engine 'understressed' and better at mpg than bhp. Not that powerful for an engine of this size.
-Bit 'delicate' in areas.  Several very minor issues that have a nasty habit of biting you unexpectedly and causing engine not want make happy brum-brum noise anymore - shortlist eg: ... crank sensor, timing belt, breathers > rocker gaskets > fill plugwells > short HTs > stuffed Coilpack, timing belt/pulley.


Turbo Weasel
-No-one really cares (aside from OOFers and Clarkson) that it's powered by the Devils juice. over 50% of new cars are diesel powered now.
-Blunt, rugged engineering. To be honest, in terms of reliability, I'd say there are three or four times as many V6 going wrong as there are the ex-BMW oil burner. I'm really not looking after mine as well as I should be, I know the oil's low, there's something wrong with the idle, massive drain when I use anything like heated rear window etc. - possible alternator going duff. But it still gets me home, albeit with a grumble.
-Thin film of black dust over EVERYTHING. Can't even check the washer fluid without having to wash my hands three times aftwerward 
-Economy. Being a diesel you can try pushing the noisy pedal through the floorpan, or drive like a nun with piles and to be honest it always returns about 25mpg. Which is about the same as the V6... but if you drive the V6 like you stole it, that mpg collapses to the teens.
-Still shifts if you want it to. Haven't been beaten off the lights yet in the Turbo Weasel. It does surprise boy racers. Especially as mine looks like an advert for the scrappage scheme.


So... hmmm, 'conclusion' - Ultimately, of course, it's your call, always will be. My insurance company gave me a lower quote for the more powerful, faster V6, amazingly.  Compare what each car offers, not just the engine - are they the same spec? MV6s (sometimes) don't have that much kit, to be honest, and without teaching you to suck eggs, mileage, overall condition, service history, tyres tread even. I'm ignoring the Weasel's issues in order to get the V6 back on the road as soon as I can, and soon as I do, the Weasel will be either sold for pence to an OOFer to strip and scrap, or webuyanycrap.com will be getting a call.

Ive had 3 all Estates, 2 x Autos and one Manual, they all died of economical repair in the end, The one that did stand me well was the Manual, (they need to be Manual to save on running cost), was used as a Works Van effectively carried all sorts of heavy Tat around plus Roof Box, Ladders etc.

I could .get (fully loaded) 34 mpg in and out and around London and about 42 mpg on a run without trying. Empty with just me and driving careful I could hit the magic 50 mpg on a long run.

In my book, there good work horses with 2.5 BMW Lumps, abeit a bit under powered compared to the same Lump in a real BM, although a £70 Chip can sort that,  definitely needs to be Manual if your after the MPG benefit, test drive it first, some are dogs with poor maintenance, Other option get or fined a V6 with LPG.

Thanks guys I'll probably stay with mine then after weighing up the pros and cons I don't think I'll be gaining anything fuel wise as mine does about 25 mpg around town about 35-40 on a run 👍

[relluf]

Over the last 1800 miles my manual estate, fully loaded all the time with all my tools ladders etc has returned according to the read out 38 mpg ,I quite often achieve 45/47 on the motorway /dual carriage way sometimes even hit 50mpg.
You do need to drop the oil on a regular basis apart from that its almost bullet proof.
Not chipped but its no slouch!!
HTH

Oooh Now you got me thinking again 😞

I had a year 2000 auto 2.5 estate in Opel trim. Didn't chip it as you need to change the gearbox first but IT was achieving 33_34 mpg overall. Mine did have a high diff, 3000 rpm was 93 mph

Should add, as mentioned above, a magic-feeling '50 at 50', so 50mpg at 50mph, which is something a V6 could only dream of. It is a nice feeling, if you are prepared to sit at a bit of a crawling pace, behind an HGV on the motorway/dual carriageway, for instance. Went on holiday to Harrogate last year and couldnt believe that after getting there how much was still left in the tank. Literally doing double-to-the-gallon what I was used to round town.

Currently my Weasel's name is mud, as the ignition barrel has jammed this morning, costing me a week's fuel budget in a taxi fare to work  But I confess that that's not really unique to Diesels, but all Omegas. 

[Goldy]

I loved mine.

[firemoth]

I hate mine at the minute. It's not being nice to me....

Ditto!!!

In standard form, the 2.5TD is a dog of a motor. Far too sluggish.  Chipped, its a decent motor, though still not a V6 beater.

Avoid the TD autos, its not a good combination for economy, and you're going diesel for economy.  As much as the Omega's manual box annoys me, manual is the only viable option for a TD.

I miss my old (auto) chipped TD Elite, it was a lovely motor, despite its "issues" when I bought it (a long running forum saga from 6 or 7 years ago ), I was a first class prat to sell it  , but it went to a good home with another OOF owner, and served them well until they part-ex it for a people carrier IIRC.

The TD, though, when it lets go, it does so quite spectacularly. Oil changes every 3k are essential.
