Yes, it's completely pointless comparing diesel & petrol economy figures, even more so comparing a 2.2 petrol with a modern direct injection dieslel like the 2.2 DTi.

However, the 2.2 petrol should still be doing better than 300 miles to a tank full. That equates to 300ml to 60l;

300ml to 13.2 gallons;

22 miles per gallon?! Do you ever rev below 2000 rpm or change up to 5th??!!!

Somethings majorly wrong here, and not just the cambelt!

The cam chain has been confirmed not to be one of the affected ones. Even when I drive it very carefully I only manage about 330 miles to a tank. Always stopping at petrol stations.

I would like to share my disappointments, with regard to the clutch wearing out on my sri. The car was bought from new in September 2004. after 51,000 miles my clutch began to slip. I took it into a vauxhall dealer only to find a &950.00 bill.

Apparently the flywheel had to be replaced. Surely this is a manufacturers defect if a wear and tear item has reached the end of its life (51,000 miles???) This should not lead to a Flywheel suffering from hair line cracks. I suggest Vauxhall review the mechanical wear and tear of the clutch assembly to prevent extensive cost to us (the customer)

I have a Vectra 2.2 DTi SRi on a 2001.

Sometimes it runs fine, then other times it cuts out and won't start for ages, or it jumps when driving and get's a loss of power.

I have had the car serviced, and had it on the computer to look for any problems, but nothing comes up.

Any ideas what it could be?

300 miles per tank seems very low. I'm getting around 360 per tank in my 2001 2.2 petrol SRi and that's a mix of town and motorway driving.

I have a 2.2 Vectra on a 2001, had it now for 5 yrs and hate the thought of getting rid of it, but near Xmas 2007 disaster struck; the chain went.

Took it to Vauxhall for an assessment, but it was no good, new engine required. It's been sitting up the drive for almost 6 months now as the pennies for a replacement keep going on other things, but that's my sob story, back on track.

I used to get between 310-340 miles per tank, town and motorway, and pulled the caravan as if it wasn't even there. Lovely car I recommend them to anyone, but watch out for the chain, it's a known fault.. apparently.

I have a Vectra 150 2.2 X reg, I get on urban journeys 32-34 mpg and on motorways 38mpg. I use super unleaded and get 380-410 miles per tank. my car also has a low carbon footprint too off 47% take into account its modified as well. She drives like a dream and love driving long distances too. been to Spain and back and that 39mpg on average. I always recommend super unleaded as I believe you do get more mileage in your tank.

Can you help? I have recently bought a 51 plate Vectra SRi 150 that has only covered 47000 miles and has been fine. Recently though, about every month or so, it loses power when you rev it past 3 or 4 000 revs, but never cuts out and always starts fine every time. This problem lasts about 2 or 3 days, then is perfect again for about another month until it happens again? Does anyone know why this is?

Cheers Rich.

Hi folks,

Before I make a total idiot of myself at my local garage, can anybody answer this question?

Have a standard Vectra 2.2 SRi 150 2000; front coil springs replaced, and the car seems very high compared to the rear.

Am I correct in saying that the springs are not the same as the other models, even other SRi's, (being a lower car)?

Please help as my car now looks rather crap, and I've got to fit new ones to the rear. Don't want an off road Vectra!!!

Cheers, Neil.

I have just purchased a 2002 SRi Vectra 2.2, and I love it. I'm averaging 350 miles per tank with 28 mpg. I have recommended an SRi to my friends!

I have a Vauxhall Vectra petrol 2.2 SRI 51 plate with 81.000 on clock. The last owner replaced the cam belt at 66.000 miles.

The only problem now is it runs lumpy and drinks oil. 1 litre every 700 miles. I changed everything 02 sensors, EGR valve, fuel filter, plugs, coil pack to no avail. It can only be the ECU now have no faults on the dash. Got the mechanic to plug in his diagnostic thing but no codes came up and no lights ever come or stay on the dash, but it's very annoying.

I don't think I would ever buy another one had 4 Cavaliers and had no problems like this crap car.


24th Jun 2011, 21:46

I've been driving a 2.2 diesel SRi Vectra for about 10 years now. Had Cav's before it. Have to say the Cav's were better, but love my Vectra.

I bought my Vectra 2.2 SRi 150 about 2 months ago, and to be honest I didn't expect it to be as quick as it was.

I don't think the car was completely standard when I bought it.

It looked pretty standard from the outside apart from the paintwork, new exhaust, and rims. Under the bonnet was all changed and replaced before I got the car.

Speeds in the gears were pretty impressive as well:

1ST- 30mph

2ND- 60mph

3RD- 95mph (gonna push it to try and get 100mph)

I haven't tried 4th and 5th to the max yet, but have had the car at about 120 mph easy so far, and it was still pulling strong.

I'll take a video of me driving the car at the speeds above in those gears, and post a link in a comment.

I couldn't see the top speed for the car only being 135mph.

What do you all think?

30th Oct 2011, 23:17

To be honest, what a lot of websites say the top speed of a car is, is normally a load of crap.

My mate's Vectra 1.8 - 130mph.

My Vectra B 2.2 SRi 150; I think it's good to go about 145/150mph.

The look on most boy racer's faces in their Corsas and Saxos, as I accelerate away and leave them behind, is awesome.

Does anyone get tiny drops of water on the oil filler cap on a 2.2 SRi?

28th Jan 2012, 02:01

Probably condensation due to having a complete alloy cylinder head.

This could be a fuel air ratio problem, and can be fixed by replacing the MAF sensor (mass air flow). Systematically check the connections to the sensor, and all air and fuel pipes for leaks and splits. Replace any worn brittle pipes, as these systems work on a vacuum pressure to operate. One crude way to check the pressure is to open the fuel cap and listen for a rush or gust of air being sucked in. Try starting the vehicle with the fuel cap open; if it starts and runs fine, you know what area the problem lies, and it can be traced to the source by systematic replacement of the parts.

What type of engine oil do I need for a Vectra 2.2 SRi?

21st May 2014, 10:43

Most Vauxhalls use oil spec GM-LL-A-025 (AKA Dexos 2).

17th Nov 2014, 16:18

I am thinking of buying a Vauxhall Omega 2.2 petrol estate. How many miles to the gallon should I expect it to do?

16th May 2015, 07:24

The timing must be out and also the piston rings must be done in...
