Fuel Economy - What do you get out of a tank? (3rd gens only)

[matty.c]

cos i get on average 60km more to the tank thats costing me an extra $4.50 to fill.. 60km would use in my car about 5.08 L of petrol..

so 60L of regular gets 520km
and 60L of 98 get me usually over 580km (same mix of city/highway)

so in fact it's saving me money.. cos 5L of petrol (cos using normal 91 would need an extra 5L of it @ your 1.40) = $7 and it's only an extra $5.40 to fill it initially with 98 octane.. which would give you the extra 60km milage...

to thats a $1.60 saving per tank

.. fill up on tuesdays..

i usually go through about 40L per week.. and yes 11.8L is pretty bad.. i have 20's and it's already in the heavier KJ verada.. i don't think it's the best combination for economy!

but thanks for the input!

yeh sorry my point for using the 98.. is that i had noticed the car idle smoother after some good injector cleaner, t/b clean.. and now that i constantly use 98 octane the car rarley vibrates on idle..
