Query about petrol consumption

[andrewsmith]

In my experience, an HEV gets better consumption because the electric motor supplements the engine so it (the engine) is always trying to work in its most economical mode. Also, the electric motor can take over and the engine stops. Braking also feeds the battery so that helps too (my wife brakes more than I do - and gets better fuel consumption, whereas I try and drive without using the brakes as I was taught).

So, yes, I get 41-45 mpg during the summer. In winter, it does go down because the battery really suffers when the temp is below 10c.

I'm getting 48 MPG in summer and 47 MPG in winter - I'm trying to get to 50 MPG but my driving style annoys my wife and all the drivers backed up behind me. Still.

49 mpg brim to brim in my hybrid. Using eco mode not sport obviously

With a couple of long motorway journeys bagged I'm at 49.5MPG. So close.

Some contributors make claims about fuel economy based on numbers they have spotted in the instrument cluster. Those claims are usually presented to portray the claimant as some kind of eco magician who is simply better at driving than other owners. In reality, the only true consumption figures are gleaned by recording the amount of fuel required to replenish the tank to the same point the fuel level was at when last refuelled.

Numbers projected on to the instrument panel should only be viewed as indicative and are actually ever-changing according to the various hindrances that militate against a fabulous average. To quote the nonsensical addition made by many that goes along the lines of......’but it does 80 mpg on a run!’ Totally pointless! Just check your bank or credit card statement and a bit of primary school arithmetic will demonstrate that your real fuel consumption was nowhere near the amazing number you tell the guys down the pub. PHEVs can produce great economy figures but only if they are charged regularly - many are rarely charged, some not at all! As for the rest; HEV, MHEV, regular petrol, the claims are nothing but bull shine.

For all practical purposes, brim-to-brim refuelling and basic arithmetic is as close as most of us will ever get to discovering our average fuel economy. Only by constant monitoring over all four seasons and taking account of all journey types do we get a proper working average consumption figure; not a scientific average but a credible average figure that takes account of most scenarios we encounter over a full year.

I use an app called "Fuelio" to record all my fillups. The average for my car since I bought it is 41.996mpg over 18,000+ miles. The last fillup was 46.42 mpg. If I look back to my winter fillups, it's much less (38 ish) so I can see why my overall consumption is lowere than the last few fillups (46,44,45,43),

Those figures sound entirely realistic, ‘alan sh’. Clearly, you are not one of the braggarts to be found on every car forum who just can’t help posting their unhelpful nonsense.
