Drop in fuel economy

[curlywurly1971]

Hi, I'm new to posting on this forum.

I have a 2017 , 1.6 HDI Berlingo and my fuel economy has dropped from a normal 58 mpg to a 53 mpg ( so 520 to 400 miles per 3/4 tank) in the last couple of weeks, I'm doing they same journey day in day out on the same road, I've checked the tyre pressures , fluids etc.  Does anyone have any ideas what could have caused this.

Many thanks

What kind of mileage has your Berlingo covered? I'm asking as a higher mileage example [or even a low mileage example that only does short journeys] could be suffering from a clogged DPF which can cause MPG to drop. Has the vehicle been doing a number of regens?

Hi Multispacer,

My car has just gone over the 86000 mark and I normally do journeys to work of 25 miles each way, 4 times a week, with a short trip shopping of 10 miles each way once a week. I nearly all of my journeys on a main A Road doing 60mph.

Thanks

I agree with Evdama and possible binding calipers, have had that affecting MPG a few times over the years, especially in winter due road salt etc.

Also agree with Shtu about the colder weather in general - and then consider it could be caused by ‘winter diesel’ being used just now in the UK, some folk suggest that increases fuel consumption slightly..?

It's cold.

Totally agree with this - last week temps most days were below 0 degrees, even the older B9's take a good 10 miles to warm up. Also don't forget diesel fuel will be on its winter grade now and wont be as efficient

Every day is a school day, I never realised that there was such a thing as winter diesel.
