I was getting back regulat 50mpg and up to 59mpg on long trips in my 64 reg automatic.
Then I boughtva spacesaver spare wheel and the extra weight knocked about 3mpg off.

I would expect lower air temps at this time of year to be more relevant.  If weight was that significant, you could get an extra 10mpg by leaving your other half at home.

Perhaps the spare wheel is full of cocaine

I think I really like our over 60 mpg piggy bank on wheels...

Went to Normandy abd back last weekend. 627 miles 60.3mpg. Did put 99 Octane in. The old bus likes it !!(1.3 68) did top up with some Sainsbury petrol in Portsmouth last year, almost immediate 5mpg reduction...

2017 Jazz 1.3 SE Automatic.

From Lemington Spa to Hatfield Galleria in Hertfordshire I managed 67.9 Mpg with cruise control set at 68mph.  I'm very happy with that.

Three years ago today I got a Mk3 1.3 EX CVT.

In first year I drove 8,500 miles at 52.6mpg (57.5mpg indicated).

Second year 7,800 miles at 55.1mpg

Third year 6,500 miles at 55.1mpg

Overall 22,700 miles at 54.1mpg, almost all with supermarket E10 petrol.

The above are "true" mpg, fibometer values are typically 5mpg higher.

Just did a 50 mile run from Colchester to London, 7oc, damp/wet roads door-to-door 66.4mpg although managed to hit 68.2mpg before I came off the M25.  Recently fit Goodyear efficient grip performance tyres and filled up with esso supreme 99.  If I'm going to do motorway driving I find the premium stuff pays for itself in better mpg, plus the driving experience is much better imo.

Did 360 miles yesterday mainly motorway and 52mpg. That's good enough for me.

I have a low-mile 2019 Jazz, 1.3l. Getting 33ish mpg now, i.e. 7.1 liters per 100km. Significantly worse than last year which was 5.9-6 per 100km. Totally clueless as to why since driving style, distances etc are identical.

After a month with my ,new to me 1.5 sport, mpg appears to be settling around 55 over average rural dual carriageway driving, About the same as our 2006 Mk i Jazz ??

Check spark plugs and air filter. They both may need replacing.
Technically plugs should last 75k miles but i've seen them start to degrade a little when they reach 60k.
Maybe time ffor a service.
