Insignia towing mpg is rubbish
« on: 05 September 2018, 22:05:24 »
We used the insignia for towing last bank holiday,towed great plenty of torque but the mpg was worse then my discovery 300tdi,it was down to 26mpg . I expected more wasnt flooring it and used cruise control where i could,and even when its not towing it only gets 45mpg if were lucky,is there anything i can check etc to improve mpg,apart from getting a remap,its a 2.0cdti 160bhp auto sri.

Guess your disco is/was manual?

That would account for the difference I would think. That and all the emissions gubbins on the insignia.  :-\

Give it a good service, the 2.0 CDTi in the mum bus was just serviced by me. Oil filter, fuel filter, air filter etc.

Noticeable improvement in engine noise, pickup and mpg.

The air filter was shocking, never been changed.

Sounds not unreasonable for a small auto diesel...

The Terracan returns 27mpg towing a 26foot twin axle Elldis & you wouldn't even know it's on the back.

45mpg is about right for that engine, it's what I get with my auto.

Is that a 3litre diesel lump?

Think AA's is the 2.1 litre (220/250) variant.  :-\

Yup, I've heard good things.

A guy in my team recently bought a 2015 E220d saloon (last of the old shape). Performance in that combination is adequate, but its a nice place to sit.  :y

If I were splurging £25k on a car, it'd be hard to look past an s-class. Appeals to me far more than an XJ/A8 or similar.
