Title: mpg of 2.2, 2.6 and 3.2 on petrol
Post by: tommoynihan on 02 November 2006, 23:14:44
I'm thinking of buying a late Omega (2003) and getting lpg installed.
I understand that LPG gives 10-15% less mpg than petrol (but obviously still has cost savings)

I've seen some owners on this site talking about the mpg on their 2.2, however there seems to be less information on the 2.6, and almost none on the 3.2.

Can anyone give me an idea of the urban/motorway petrol mpg comparison of the three engines ?

Thanks.

(p.s. I've looked at the Parkers figures, but they only give a combined figure, and all look suspiciously close to one another)

Sorry, mines only a 3.0l, but if it helps, I average 25mpg day to day, up to 33mpg on a long empty motorway run (at around 80 - 85mph)

I'm the same as TB.  

The smaller engines seem to have more of a benefit in town than on the Motorway.  Knowing what I know now, I'd probably get a 2.5/2.6 manual MV6.  However, the 3.0 Elite Auto is quite nice and I have no plans to trade it in.  I'm just still not used to the price of petrol over here  >:(

Daily average (50 miles to and from work) around 25 - 27 mpg. Long runs up to 32 - 33 mpg.

I get 30-32 in town and 35-38 on a long run: 2.5 manual.

Note, in general, the 3.2 gets the same as the 3.0 and the 2.6 gets the same as the 2.5

just came back to brackley today, reset the gauge when i left London.... 50 miles of motorway @ 75mph got 40.6 mpg.

Then cause it got rammed around Oxford i took to the lanes, several over takes up to 5k revs... generally doing 70 for about 20 miles of lanes and having to go via Banbury to drop off a freind... resulted in an average of 36mpg...

Not bad considering i was booting it several times, and the car was quite full....

Around town i generally get about 31mpg.

Note also that manuals get considerably better mpg than automatics....

31mpg in town  :o I reckon you must push it everywhere  ;D

How about 1/2 that figure for mine on lpg   :o

I've come to the conclusion that a 2.6 is probably the best option.....it doesnt seem to use much more fuel than a 2.2....plus youve got the extra horses  ;)

Only downside is if your getting it converted to lpg.....it will probably cost about £400 more for a V6.

Unless you diy it......Martin Imbers the one to ask about that......he diy'd his 2.6  :y

never used to bypass today, came back from Chacombe on the back lanes for a bit of fun!  :)

Think if my 2.2 gets written off for any reason by someone, I will replace it with a V6. Cause i wouldn't mind the extra power!

If i can't get a Diesel for my Euro trip car, then it will have to be a V6  :)

Actually your car did spring to mind....  ;)

Although i could get one off eBay i'd prefer one i knew the history of.

Plus yours must be one of the best maintained ones around.  :y

i don't often give mine stick, but coming back today down the back lanes past 2 slow moving cars, in 3rd ... with no one else in it, but me...(being 10 stone) it doesn't have shift! Really perks up now from 4.5k revs right up to 6k...

I have noticed that 97 octane gives me 40/50 extra mile per tank full as opposed to 95 octane.

Worth the extra 4p. :y

Unfortunately not much as i would like! - Got up at 7:30 today (yes thats AM!  :o) - and cycled into Uni, just over 5 miles... in London traffic it certainly wakes you up!! Feeling good about it though, done 175 miles since the start of October on my bike, but had a few near death experiences with drivers cutting me up. Why is it they assume your going dead slow? i cruise @ 20mph generally and nudge 28mph going down hills.

I was on some roundabout and a women in a Civic just did't brake and cut me up right in on the junction, she was quite surprised to see some guy literally bashing his hand on her drivers door window showing her the V sign doing 20mph....

Then you get people who are pi$$ed off you undertake them and try and ram you off the road! Ahh all good fun.


Anyway getting cracking on my Project for uni, i am making a Multimedia Map for theme parks that will run on mobile phones, in particular the phones that run the Symbian operating system (Nokia N70 N80ect...)

Its going to have a live up date queue system where using the software i am marking for the phone, when in a theme Park such as Thorpe Park it will give you live updates on ride queue times, navigation via maps to park facilities, and download technical info on the ride itself...

Got spurred on today by my project Supervisor who said if you continue the way you are, i will recommend your project to be showcased at the "Made in Brunel 2007" which shows the best work from Brunel University in Islington London  :)

I drive a 2.2 manual and get 24 mpg round town & 33 on motorway at 80 mph.  

Looking at the other posts I should ease off a bit - I blame the heated seats & aircon for the extra juice.

I wack mine on Eco around town... even more now that its so cold Eco seams fine. But it does tend to mist up more than on Auto. But on a motorway run i leave it on Auto....

I drive quite hard and most mileage is around town or commuting along country lanes with speed varying between 20 and a hell of a lot faster.

I get between 15 and 17 on gas, I also got 17 on gas from Okehampton to Worcester cruising at speed limit with a large van on the back - I got 11mpg through part of Cornwall, foot to floor off lights and up hill with the van.

Unfortunately I haven't done a long run on gas without a caravan but I'd guess around mid 20s to low 30s would be about right.

It still needs some tweaking however as the mixture is a bit out in a couple of places.

They say don't tow on gas and don't exceed 80 on gas, well I tow on gas happily and I can cruise on motorways happily.

I used to get 22 on petrol out of a 2.0 auto, same from a 2.0 Carlton GLi high comp. manual. Prior to that my Sunbeam anywhere from 20 to 35, but I did take on 2.0 cars and win.

The V6s are thirstier but not overly so and the 2.6 is an excellent comprimise not much slower than the bigger V6s and a little more economical, similar performance off the line due to gearing. 2.0 is underpowered but not painfully so. The extra power and torque is brilliant as it the engine note. A gas V6 is cheaper to run than the 4 and has similar costs to the 2.2 TD but I have an autobox, 2 more cylinders and 60 more bhp

Do you mean that a gas V6 is cheaper to run that a 4 cylinder on petrol ?

Yes - as said similar costs to the 2.2 TD
