TeslaFi "Gas Saving" for the UK

[Compuguide]

Our peculiar system of Miles for Road distance measurement but Litres at the petrol pumps complicates things when trying to set up TeslaFi's "Gas Saving" feature.
For the uninitiated this is a TeslaFi statistic that is designed to show how much cheaper the cost of electricity is compared to what you were consuming on your old I.C.E
Now, in my case my previous car was a 16 year old Nisan Micra Tempest.
It was pretty inefficient, at about 35 miles per gallon
So here are my sums:-
miles per gallon 35
miles per litre 7.698924 [35/4.54609 (litres per imperial gallon)]
Kilometers per litre 12.39019 [7.698924*1.60934 (Kilometres per mile)]
Have I got this right?

Below are the numbers I have plugged into TeslaFi. (The "kWh Gas Equivalency" number of 9.7 for a litre of petrol I got from Google)
The "Gas Cost" of £1.25 per litre is from the forecourt of the garage I used to use


I'd be interested in anyone else's numbers.
Thanks

As an alternative route (which might validate the route you went?)

35MPG Nisan Micra Tempest

Petrol £1.25 a litre

1.25 * 4.546 = £5.6825 per (Imperial) gallon

35 Miles for £5.6825 = 16.24p per mile
35 miles is 56.32704 kilometres, 56.32704 km for £5.6825 = 10.09p per km

I think converting refined petrol to kWh of electricity is fraught ... I can grasp setting light to some petrol and releasing some energy , but what about well-head-to-wheels? or even from prospecting-to-wheels? vs. Dogger-bank-Wind-prospecting-to-wheels ...

BNP Paribas report touches on some of this, there are many ways to skin the cat like most things with EVs and power- efficiency,ecological impact etc.

This is what I got mine set as.

According to TeslaFi I already saved £2 from my pottering around last 2 days. We'll see what a weeks commute will be like

Not sure about your numbers. When I feed them into my TeslaFi the Gas saving is negligible

Not sure about your numbers.

Neither am I.

My old BMW had 27 MPG so I'm trying to compare to that. The fuel is in £ not pennies? so 1.25 is correct?

Then "imperial gallon of gasoline contains 28.0611 KWh"

Yes, I think 1.25 is correct but the black art of TeslaFi's underpinnings evade my simple brain (whada I know?)

 

[Mr Miserable]

I'm not sure putting 1.25 is correct when everything else refers to gallons.
I think you should put 5.675 in that box (1.25*4.54) ie cost per imperial gallon.

Thank makes sense, thanks.

That looks much better now.
