Whilst I enjoy trying to get a good return from fuel i try not to be a bore and bang on about it - but today I have driven from Lanarkshire to Hampshire, a distance of 392 miles, at an average speed of 60mph and average fuel consumption of 61.4mpg.

The last tankful, 590miles at an average of 59.9mpg (that was filling up in Lancaster on the way north on Monday).

 

I was gob-smacked!

 

A tidily 1.0 engine / mild-hybrid DSG in a big-ish estate car at the legal limit wherever UK motorway traffic permitted, impressed!

 

This is a loan car whilst mine is ‘in dock’ so I am hoping that when I get my 1.5TSI (manual) back it will be somewhere in the mid-50s mpg at least.

60mpg at 60mph average is very good for a petrol engine and the 1.0tsi is a comparatively efficient unit but based on my limited experience of driving on UK motorways, I think it is about right in near ideal temps.

If you are a naturally economical driver who does not brake much then I don't think the 48volt mild hybrid system would have contributed very much to your results.

I see no reason why you will not get similar consumption, maybe better, from your manual 1.5tsi (with cylinder deactivation) in similar circumstances.

The mk4 has exceptional aerodynamics for its class and that has got to help at higher average speeds.

Most of the way when North of Manchester then.

Absolutely - and stunning scenery alongside the M74 & northern end of the M6. 

 

It was the M42 east of Birmingham that slowed me down - anything from 40mph to a standstill. Not what I wanted in the midst of a 6+ hour journey. Plus side is the Octavia Mk4 is a nice place to be; and another nice surprise for me, & a plus point for the 1.0 e-Tec, is that it doesn’t sound stressed or laboured even on long climbs such as Shap or Beattock even though its a small three cylinder motor.

That was your "big mistake"; you should have used the M42 west to the M5 rather than east to the M6(either). The M6(toll) southbound is rather better since the M42 west is slow to ok rather than dead slow to stopped.

I've also been very impressed with my 1.5 TSI manual which can achieve averages of 60mpg when driving at 50mph on the motorway (there's an average speed limit for most of this journey with a mile either side of 30mph roads). ATC is active for a lot of this but it shows just how much economy you can get from the engine.

 

Other shorter or faster journeys are usually in the 45/55 mpg range.

Even my petrol vrs gets ~50mpg on long journeys, must be very aerodynamic!

@Mark Hiscock @Darkness22 thank you, encouraging to hear that my 1.5 is likely to return good figures too.

Just spent a week in scotland with me plus 3 in the car and a boot full of luggage.

Sticking to the speed limits i'm getting 60-65mpg using the brim method to calculate, that's from my 2.0D 150PS love this car,.
