Hello
Does anyone know what the difference the fuel economy is between a 2.6 and 3.2 would be. The reason being i would eventually like to get a 3.2 estate if the correct one came up.
Cheers sorry can't get smiley faces, damn computer.

I'm not sure Kieran, but as you've probably guessed it will be slightly lower mpg. Not as much as you might expect because the engine doesn't need to work as hard.

Fuel economy is more about "how you drive" rather than "what you drive".

Do you mind me asking why you want to move to a 3.2? What gains do you need?

If you want more power and speed, then I suspect that the mpg will be considerably lower then you'd hope for and not really something you should be worried about.

As far as I can tell that would be the only reason for moving to the bigger engine, and if you do do that then fuel consumption / economy is a bit of a misnomer.

The other reason to consider the bigger engine might be towing, again fuel economy is going to suffer with a caravan on the back no matter what you drive.

I really fancy trying to get and hold on for a long time the best Omega built. A 3.2 Elite estate would be brillant with all the toys.Some do come up and really fancy one. It would be a long term car.Yes i do tow a caravan fully loaded. The real reason i am asking is the missus will want to know so i have to be prepared with answers or lies to justify a purchase
Cheers

..indeed they do..

if consumption is an issue and its a long term purchase, lpging seems to be the way to go - several on here have done it.

Kevin Wood is your man on the LPG front. If you do a search you'll see that someone somewhere on here (with too much time on their hands) has shown that it pays for itself in about 2 to 3 years. With a caravan probably sooner.

LPG would be the way to go and being a long termer it would pay for itself eventually. Coming from NZ where we had Holden Commodores a large engine appeals to me and they have been using LPG and CNG for about thirty years or so.

Like has already been said, it all depends on the way you drive it.

I've just checked out the fuel consumption from my Miggy since I last filled up, and it's returned just a smidge under 38mpg - not bad for a 3.2!  But ours has a manual box, and was covering mainly motorways with a bit of town driving.

Filled up with LPG today after 260 odd miles of mixed urban and extra-urban driving and it cost £27.something. so between 10 and 11p a mile for mixed driving. My LPG conversion has almost paid for itself already in 7,000 miles.

The only downside with an estate is that it's less easy to hide the tank. You might end up having to settle for a spare wheel tank with relatively small capacity. Then again, if a 2.6 on petrol is affordable a 3.2 won't be too much worse. You'll already be in the top road tax bracket so no nasty surprises there either.

In a way, it's pointless discussing MPG ad nauseum as the biggest factor is driving style, especially in a powerful, heavy, automatic car. Suffice it to say that if your driving style stays the same, you will probably only lose out by 1 or 2 MPG. Of course, you might be tempted into letting it slip a bit more than that.

I've never towed with a 2.6 but a 3.2 might well make a worthwhile difference. More torque might mean being able to use lower revs, thrashing the engine less may even improve MPG.

Mine happily cruises at 55-60 with a full towing load at just over 2k RPM locked up in top, changing down on the uphill sections. Does about 18-20 MPG on petrol under such circumstances IME.

BTW: Did you resolve the MAF sensor issue, Kieran?

Hi ya Kevin
Fitted the new MAF sensor about two weeks ago and checked any fault codes on a cheap scanner and nothing came up so hopefully all fixed,fingers crossed . Don't know if Albatross fixed his problem thou.
