Since I've found this:

Site gives more of a technical overview of each series, a bit like the old book "45 years of Holden" I have at home that finishes at VR.

Reading further on the net, I've come across some astounding owner fuel consumption claims, VX base model sedans getting highway consumptions in the 5's and 6's... although 7's are more typical.

Dad's VY wagon will sit on high 7's with a combined of about 8.4 last time for country and some town driving. I did Syd to Melb once in a diesel XTrail hire car and that returned high 7's, so it really makes the torquey Aussie 3.8 and 4.0 with a 4 speed auto look pretty good, considering petrol is cheaper than diesel and is far cheaper to maintain.

Has anyone here achieved 6L/100km highway figures with the Ecotec?
I've got a cammed 5L Caprice - I put a VT distributor in it to give it CKP and CMP sensors and converted to 8x LS2 truck coils and sequential injection from batch fire with a Wolf V550 and it dropped fuel usage from 17.5L/100km to just under 14L/100km on highway and picked up a lot of torque in part throttle driving.

The sensor resolution from a distributor for both triggers isn't the best but it works.

7L/100km would be nice but a cam and 8.4:1 compression ratio isn't a recipe for using fuel efficiently

I'm tempted to pick up an L67 Caprice as well to have some fun with.
