[Field Marshal Dr. Opti]

I regularly drive the 400 mile round trip from Lincolnshire to Powys in my 2.6 MV6. Petrol consumption is ALWAYS in the region of 31/33 MPG according to the trip computer.

I've just recorded a piss poor 25.8 MPG for the exact same trip.........(less traffic than usual, too.)

Any idea why, chaps?.

No warning lights showing, and she is running faultlessly. Air filter?....

[Darth Loo-knee]

Are the multi rams working?

[Andy H]

Thermostat sticking open?

When was the car last serviced.

[Field Marshal Dr. Opti]

Are the multi rams working?

How can I tell Mr DLK?

[Field Marshal Dr. Opti]

Thermostat sticking open?

Possible.

 Ticking over on the drive the fans will eventually cut in. In normal driving the temperature needle barely gets off it's stop......especially with the AC working.

I assume all tyre pressures were checked.

Why not PM him - am sure that 'The Great One' will impart his vast knowledge

[noel]

fuel filter maybe  ??

[Michael2.6]

You can tell if the multi rams work by a good blast of the throttle

you should see multi ram move on the bag pipes

Thats not going to help, you need a new thermostat for a start

How about a rubbish tank of petrol?  There is some about.  I've not had problems with the Omega but the bike has pointed me to avoiding one particular outlet due to abysmal running.

Definitely.  In my very recent experience a dead thermostat wipes off 4 or 5 mpg straight away.  Keep the A/C off - as you imply, the extra cooling caused by the heater matrix trying to warm the cooled cabin air is enough to push the engine temperature down noticeably this weather.

Lies deep between the creamy bosoms of the lusty V6 if memory serves . Why do Vauxhall make it so inaccessible to the novice mechanic such as myself.... ?


I should have asked Mark to replace it when he fitted a new oil cooler for me......DOH....
