I would be looking at a million other things to save fuel, rather than skimping on fuel quality. Which will probably save you nothing, may even work out more.

I run 1 heat range colder plugs 7's and they work fine.
The factory plugs are fairly cold by OEM standards as most OEM plugs are a 5 heat range compared to soarers/toyotas which are 6. Hence I wouldn't think you could get away with running 2 ranges cooler.
Which rpm range is there pining, if it is below 4000rpm the ECU should compensate.

Has the oxygen sensor been changed? Could be slow to react, ie lazy oxygen sensor.
My UZZ32 has drinking about 18litres per 100km in HEAVY peak our traffic. Once I change the original OLD oxygen sensor she does about about 13-14litres per 100km.
Heavy traffic means 1 hour 20mins to travel 25km.
