T32 Petrol (4WD) Fuel Economy
I was asked by Jalaski to start a T32 fuel economy thread so we can all share our figures.
Naturally conditions and driving styles have a big effect on that. Fuel also plays a big part as well.
I’ve tried many brands and types. The worst being the smaller independent ones that use 10% ethanol blend, or even their standard unleaded. With my car there is even a difference between the majors as well. The one I find best for standard 91 octane is Shell, but best of all fuels is BP Ultimate 98. Shell Vortex 98 is only marginally less than BP (around 50klm at most) and their prices are the same.
The difference between an independent and BP Ultimate 98 is between 150 -200klm klm per tank – that’s a huge difference. 7 Eleven 98 octane (Mobil) gives me the same range as Shell 91, as does Caltex 98, so fuels aren’t fuels as they say. I have found the extra you pay for BP 98 or Shell 98 is worth the expense over the tank compared to Shell 91 or the independants and you get the cleaning additive in the 98.
I’ve been involved in fuel testing at work and when the tests were done BP 98 was the only fuel that consistently had at least and in some cases over 98 octane.
My average since I got the car is 7.2 litres per 100 klm and I’m now over 23,00klm. It was reading 7.0 but then I had a lot of work to do with the new house, so did quite a few heavy trailer loads over quite a distance. It jumped to 7.1 pretty quickly then settled on 7.2 and hasn't dropped back since.
You'll notice 855 to empty in the shot above, that was just after filling up and travelling 8.2 klm to work through the suburbs. At the servo straight off the freeway it said 880. By the time I get home this arvo it will still be on around 850, but I will have travelled 75klm to home. 980klm is the best range I have seen on the readout. The best I've got is 6.1 per 100klm according to the readout and that was a trip from work to home (75klm) -
I pretty well use a fuel conserving driving style nearly all the time. I do roughly 800-1,000klm a week so fuel is quite an expense. The only relief I get is if I feel like riding the Harley to work on fine days, it gets around 4.5 litres per 100klm haha.
I don’t race off the lights. I don’t dawdle either but only use around half throttle. I also lift off just as I approach the crest of a hill as well, as soon as it starts to pick up I back off to maintain speed. I also only use as much throttle to maintain speed on a climb as necessary, you can put your foot down a bit further and gain no extra speed, but the readout jumps up higher because you are putting more fuel than necessary into the engine to maintain that speed.
I try to keep a steady throttle with as small a change as necessary in traffic to keep up and use cruise control whenever I can. I also do a lot of freeway driving. Around town just going to the shops and back home will get as high as 8-10, so pretty much on par with everybody else.
You'll see a couple of shop runs in the second picture, up around 7-8. A run from home right into the heart of Brisbane will show around 7.5-8.5 average over the trip depending on the traffic.
There is a school of thought that says get up to the speed you want to do as quickly as possible. This is OK in theory but heavy acceleration drops your range to empty very quickly. Slower acceleration to speed is the better way to conserve range. Also I find it better to just leave it in auto. If you use the manual shift at speeds above about 50kph it locks the converter in and you use more throttle to gain speed compared to just leaving it in auto and letting the converter slip.
Let’s see what others are finding out, post your figures and fuel thoughts so we can compare and share driving tips for better economy.
