Pete, I cant give you an accurate figure on the Jack at 90 kph.
What I can tell you is that last year touring the outback, towing a
C/t consumption dropped from 5.5 k to a litre at 110 kph to
7k per L by staying under 100kph. I am assuming I can get it down to 8k/L by staying at around 90kph. That is the same as I get country driving, not towing, at 110kph. I think the auto does
about 2500 at 100kph. You may find the revs may not drop that much at 90kph as you may spend more time in 4th, but the savings come from reduced drag from the air & the motor perhaps
producing better torque at that speed. The Jack is only a touring
driver, the 2 Peugeots I use went from 13 k per L to 16k. That
equates to 6.25 L per 100k down from 7.7L/100. That is serious
diesel type economy, especially from a 2L auto 4 speed.
Mate ,I felt like I was stopped when first doing it, but now I am
used to it & find I'm not the only one doing it. I already save heaps by driving low value cars (no depreciation) & I reckon this
is the only way I can cut fuel use. Its useless complaining about
the price, look to what you do control. cheers...oldbaz
