Has anyone worked out the effect of weight on mpg while towing?
I currently have a trailer that weighs around 750kg empty and about 1100kg loaded. It doesn't need to be this heavy, but to buy a new one or build one up may take ages to recoup the cost in fuel. I was thinking of doing some work on my TDi for more performance, but thought weight reduction may have the same result, but the cost may or may not work out.

SubscriberI dont have any calculations but over Easter i took my camper to Bendigo and while there filled every available space with firewood to bring home (from SIL's property).
I did notice the weight in corner and while braking but didnt notice any real increase in fuel consumption but may not have been long enough a journey to check.
Once rolling at speed i didnt even notice it but hills killed the speed especially running 32's.

At a constant speed, the weight would have little effect. The wind resistance might even be greater.
With a lot of acceleration and braking or a lot of hills, the effect would be much greater.
I don't think there is a single, simple answer that would be correct in all situations.

I think a constant speed is a near impossibility with a 300 TDi, especially when towing some weight, there are hills you would never feel otherwise
