VZ Executive
Hi guys,

Recently purchased a VZ Executive seemed to be getting bad fuel economy. Looked up Holden spec’s they say that I should get 11/100km around town... but I only seem to get 18/100km....

Wondering whether this is normal economy or do I need to get it tuned or something…?

Also will putting an exhaust on it improve its economy or make it worse...?

Whoa, I thought 14/100 on my VZ wagon was bad!, I think most are getting between 10-12 city and 7-10 on highway.

Exhaust , tune and CAI will definately bring it down, that what i will be doing soon.

VZ Wagon
i get around 14 in my wagon, depends on your driving style. I have a bit of a lead foot, when my wife drives it she gets around 11 or 12, so it is completely subjective. I get around 9 highway driving.
If you are gunning it at every light change 18 wouldnt be out of the question

Are you working the formula correctly? How many kms do you get from a tank? Sure the handbrake isn't on? ;)

ive had mine sitting on 7.4L/100km (dipped to 7.2 on occasions) on the freeway the whole way from canberra, down the federal and hume highway, around town is usually around 12-14L but i do small km's in town, and they are short cold trips,



all depends on your driving, the kind of driving you do, and the environment you drive in, also dont judge the economy by the computer, its not usually accurate until you get a bit of driving behind it to get a long average out of it

acutrally highway driving and cruise control with the exhuast will bring it down, city driving with the full exhuast (extractors ect) will be higher
