Noticeable drop in MPG after service...

[Booner!]

Not a biggy... but my MPG has dropped since my last small service.

For example, my mpg reader would say: 67mpg cruising at about 30 in 4th gear, now it says: 45mpg or lower..

Thicker oil or tyre pressures come to mind... but I am no expert... any ideas? Doesn't bother me too much because I just about get 35mpg on daily commute still (poor I know...)

This is based on day to day usage over the passed few months and I have it up on the dash all the time to remind me not to boot it. Usually it goes to 67mpg ish with my foot at cruising position....now it seems to rest at about 45-53mpg at the same foot positon.

I know it's very inaccurate, but when you drive to work on the same roads doing the same thing every day there is patterns.... my pattern has changed and only since my service.

So based on the above, what could cause this? or have I turned into an OCD freak.

 

[Booner!]

Yes yes I know.... I get an AVERAGE of 35mpg on the 15mile journey, which is frankly terrible etc.

What I mean is, the onboard active MPG reader shows roughly 67mpg upon cruising....whether it's doing this I don't know....but now it's doing 45-53ish on the active mpg reader....which affects the average slightly.... this has only happened since my service...that is all. I just wanted to know why it would do this?

Do I need to take a photo of what I mean?? *wipes sweat from forehead*

I find it useful to prevent me using my heavy foot from making my asthmatic engine cry any further.

booner..

out of interest, what do you get on a motorway trip?


need to replace my old vectra with something that has sensible MPG soon.

to work & back, i average around (15 miles to work) 36mpg (lots of stop/starting and a bit of motoroway)
on motorway & bit of a roads trip (110 miles) 55.2 -70mph top speed
on motorway & bit of a roads trip (110 miles) 42.4 -80-85mph top speed

I get something like 39-41mpg MAX on a motorway trip doing about 80mph fluctuating. Avoid the golf if you want MPG satisfaction, you have pretty good figures already (in comparison).

This is why I use the real-time MPG dial to control throttle/economy

The analogue needle is the best one to use, not the digital one

I don't have an analogue, it's not a feature on the dash.

Here's a tip for you guys... instead of driving with your eyes glued to a dial or digital read out try looking further up the road. You'll save much more fuel by anticipating the road up ahead

Thanks for that, I never learnt that in my legoland driving experience. I know the roads to work so well that I am engine braking and anticipating every day, which has saved my brakes and fuel considerably over my driving a year ago. But thanks for the tip

My average trip to work gets me 35-36mpg. If I take the dual carriageway I would get 38mpg max
