Fuel Consumption

**azn_k3nt** · 17-04-2011 01:42 PM

I've been getting 8.0lt/100km oO been getting about 740-800km off a tank, 34psi on all 4 wheels and BP 98 ultimate

Driving from station > home via backstreet and the occassion trips to the city and westside on weekends but mind you, driving on weekend nights is no different 2 driving in peakhour =="

i recently got my 05 euro luxury manual stock filled up 55L bp unleaded 95, drove till warning light came on filled again was 54L distance travelled 674km, so consumption would be 8.3L/100km?

driving to work on 60/80/100kmh roads, lead foot few times, hopefully on this 2nd tank i can lower it since im use to the car now hehe xD

54 litres divided by 6.74 hundred kilometres = 8.0118 L/100km.

For those that are interested; in the old-ancient pre-1971 measurement: 8.0118 divided by 4.54 (litres in an Imperial gallon) = 1.7647 gallons. 100km divided by 1.6093 (km in a mile) = 62.139 miles. 62.1389 miles divided by 1.7647 gallons = 35.2 miles per gallon. Or you can use the constant 282.2 and divide by the L/100km i.e. 282.2 divided by 8.0118 = 35.2 miles per gallon.

I don't know why we use L/100km. Why not km/L? Surely most people would rather know how far they can go on each litre of fuel. In this case it would be 12.5 km/L. So if you'd estimated that your car had 10 litres of fuel remaining, you could easily calculate 12.5 x 10 = 125 km range.

If you like to play with figures try this from my CU2 Auto - 989kms / 61.63 lts

On my current tank I have 879kms & the low fuel light is not yet on / last fill was 11th April / average speed on this tank is 85kph.

o.o man ur lucky

to be that fuel efficient LOL

That's cos his mainly freeway driving... His average kph is 85km/h.

**buddah51au** · 09-05-2011 11:08 AM

Sorry to disappoint you mate, but there are no freeways where I drive. I will add that for 300km on my current tank the car was fully loaded with helping someone move. I could not have fitted anything more at all in the boot, the back seat was loaded almost to the roof & 2 full milk crates tied to passengers seat.

For those of you that know QLD, the current tank is 3 trips between Hervey Bay & Gladstone, so about 85% on the Bruce Goat Track.

Bruce is still a highway, with load or not at 80-100kph it's always the fuel consumption sweet spot, especially with CU2's gearing. Your consumption will always be significantly lower tha us metro folk.

Sure, driving the Bruce Goat Track will give better consumption than driving in the city, but it is a poor excuse for a hwy. Potholes & roadworks everywhere makes the trip a pain in the butt. Don't forget the Gin Gin Range kills fuel consumption. I have already lost 1 rim to a pothole, so night driving is a big no no at the moment.

A major problem for Metro driving is the Auto wont pick up top gear below 75kph.

If you want KM/L that's easy, as of my last fill 36,628kms / 2592.22Lts = 14.12997353 km/L. Is that good enough?
