I used Fuel Map to monitor our fuel usage for our trips each year. It gives fuel economy for individual fills and also fills between any amount of fills between two dates. The screenshots below show total fuel figures, as well as individual fills
Our trip this year was 6284km, up from 5402km in 2017, 5427km in 2016, 6204km in 2015, all four trips were for 6 weeks duration.
This year I have upgraded my Colorado to an Iveco Daily. It is also about one tonne heavier and I thought this would have some bearing on our fuel figures
Fuel economy for our 2018 trip was 6.50km/l or (15.48 l/100km). Fuel economy ranged from 5.76km/l or (17.36 l/100km) to 7.92km/l or (12.63l/100km).
Fuel economy for our 2017 trip was 6.29km/l or (15.94 l/100km). Fuel economy ranged from 5.8km/l or (17.23 l/100km) to 7.24km/l or (13.82 l/100km).
The fuel consumption was started when I filled up in Ulverstone, approximately 15km after I left home and ended in Burnie after I had unloaded and unhooked and driven approximately 15km to a service station. The Iveco was loaded to around 7000kg, which was checked on the local weighbridge, however I misplaced the weights which were well under total legal limits, except the 5th wheeler was just over its legal weight when I weighed it. I did transfer some weight onto the Iveco, however I never reweighed.
I was extremely happy with the figures, as they were a little better than last year and we were about one tonne heavier. These figures were achieved by driving at 87km/h, checked with GPS. which was 93km/h on the speedo, a little slower than the 90km/h with the GPS in the Colorado. We also slowed down if the road surface deteriorated. There is a lot of very rough bitumen roads once you leave the main highways.
We started fuel consumption at Ulverstone Tasmania on the way to the Spirit with 56641km on the 16th June 2018 and ended after I refilled the day after I returned home in Burnie Tasmania with 62925km. This gives true round trip statistics and was 62284km in total.
Normally I am a big believer in just filling up when getting close to empty or around 1/4 tank when towing, unless we are in the outback. This year Dianne and I travelled with another couple, Phillip and Sandra Cowmeadow. Phil hates to let his fuel tank get under 1/2 tank, even when in populated areas and has access to plenty of places to refill. We even had one time when we were planning to refill early the next morning. Phil then came across a service station, five minutes after our conversation over the UHF, he proceeded to enter the servo and refill even though he still had plenty of fuel left. It was very comical at times. I did try to source cheaper fuel this year, especially when not towing.
As I have now upgraded to an Iveco Daily, a new vehicle and am now carrying a bit of extra weight will make for an interesting read over the next couple of years
