VYII Calais 5.7 V8 Economy
I'd like to share my fuel economy readings for comparison.
I recently purchased a 2004 VYII Calais 5.7 V8 (obviously an auto) and am well please with my purchase...well done GM Holden.
Whilst I knew it would be a bit thirsty, it never gets economy like the AS (Australain Standards) specs you see listed in motor magazines, or on Redbook eg. Hwy 8.5L/100km, City 13.5L/100km. ( I would love to find out the exact testing procedure used
).
I am a normally conservative driver and travel a mix of light traffic 60 & 80 kph zones, and some 90-110 kph zones, I average 14-15L/100km. This is for light acceleration keeping up with the general traffic flow. Of course pressing heavily on the "loud pedal" sends the fuel usage into the clouds
As the Calais has a multi-display trip computer, I usually have the average economy display on, and notice whilst cruising on a freeway section of 100-100kph, it will sit on about 11-12L/100km...or in a 90kph section it can drop to 9-10L/100km.
I'm sure this is normal, as it's recently been serviced, but would be interested to know othe peoples figures.
I have long term plans (having done some internet researching) to install a cold air induction kit, K&N air filter, which I would expect to power, economy and bottom end torque....any suggestions?
p.s. I am impressed by the communtiy spirit to share and solve questions from members in this forum, well done people
