Fuel Economy - What do you get out of a tank? (3rd gens only)

[Billy Mason PI]

I posted somewhere that I gave E10 another go but Maggie drained the tank quick smart. So I decided to put some Mobil 8000 (98 Octane) in the other day and see how she went with that. The DTE at the time said I would get 200km out of what I put in. However, I managed about 260km, which is the equivalent of a one way trip to work for me. Looked promising, so I filled it to the brim with Mobil 8000 yesterday and will post back how many kays I get out of it once it runs out.

Well I pretty much emptied the tank of 98 PULP last night and managed to get precisely one week of driving out of a tank. (Filled up last Thursday night 9/8/2007 and refilled last night but with ULP)

Dist. Travelled 724.4km

Litres of fuel: 64.82 (this was on the receipt)

Litres/100km (average): 9.2L/100 (however the trip computer read between 10.1 & 10.4 all week)

Using google map, I calculated that 22.9km of a one way journey is suburban/town (50-70kph) driving and 44km is freeway (90/110kph). Therefore, 34.2% is suburban with 65.7% freeway for those who care. In summary, the 98 PULP provided no benefit in fuel ecomony over 91 ULP which is what everybody probably already knows. I can get these figures on ULP (best of 789km). Interesting to test it anyway.

yes this is a good result but i was under the assumption that 98 was better for your car then 91??is this true

To get average fuel consumption figure divade fuel used with kilometres travelled and multiply result with 100.

64.82/724.4=0.0894*100=8.94 or simpler 6482/724.4=8.94

It is too. I used this calculator but I must have punched in a wrong digit. https://home.iprimus.com.au/foo7/fuel.html Thanks, I will remember the formula for now on though.
