has any one got any ideas on how to bring the fuel consumption backfrom 15L/100km round town and about 13L/100km on the open road! ive being driving worse than a grandma (and yes its been painful lol) with not alot of difference. is there any sencors i could clean to drop it back abit. i know these motors were not the cheapest to run but isnt this is getting abit steep! any advice! thanks

Remove the supercharger drive belt.

I can't understand why anyone would buy a big car like a supercharged V6 Commodore and then freak over the fuel consumption.

Farmers in my local area keep buying brand new tractors and f.ing Range Rovers (diesels) and rave on about how much cheaper they are to run than older models despite spending hundreds of thousands of dollars on purchasing them. *Facepalm*

thanks for that bit of rare and helpful info .who does that and where can i gt it done.you would have thought your 8 and my s/c 6 should have roughly the same fuel consumption aye! look forward to your reply. thanks

have you done the air filter! regular maintanance will help your cause.

I;ve heard it is recommended to replace oxygen sensors every 80,000 - 100,000kms. Not sure how much truth there is in that, but considering they do play a pretty important part in fuel injection operation, it might not hurt to look into that more!

Just out of curiosity, I can understand that restrictive airflow from a blocked filter will work like a choke on a carburetted engine, but with a fuel injected setup, would a blocked filter actually cause more fuel usage as a direct consequence or would it just mean a sluggish engine resultign in a heavier boot from the driver!

This is the reason they have 02 sensors.need I say more. Ok I will because if I dont ,I will get an unusuall response. They used an air filter for a reason and then recommended you change then every 5 to 10,000 kms. Restriction in airflow results in increased fuel usage carbed or injected.

Just done a trip from Tauranga to North Shore and back and got an average of 9.2l / 100km

that will just cause it to run like a bag of shit, i have a Super 6 running a 10psi pulley with the cat converters removed maybe you have blocked cats! that will add to your fuel consumption i get 13.5 L per 100km around town and 8.4 L per 100km on the open road driving to Kaikoura and Nelson most weekends no bullshit, and that's boosting it pretty often.

if an 02 sensor fails on a L67 engine it will throw a check engine light straight away, like mine did (due to blatant driver abuse getting the exhaust gas temp too hot due to doing skids in a paddock for about 1/2 an hour.

thanks guys for all ya info . as i said before i know that they use more gas being a s/c but not 15L/100km round town! i will remove the cat i think. oh in doing so will they fail it when it goes for its next wof! thanks

No it wont fail a wof for running rich,unless its blowing choads of fuel smoke.

check your plug as wellthey are only about 40 bucks from holden

just done plugs and new leads. i mean will they fail a wof if i take out the cat coverters! thanks

Do those engines run a airflow meter or map sensor!

Bollocks! Get your figures right by comparing 2 cars of the same year. And irritating whine!. cant say my mates one has an irritating whine.

What tyre pressures are you running and do you check them often!

typical Ford owner he forgot to mention that a Super 6 Commodore comes standard with Independent rear suspension and side airbags (which are still optional on the FG by the way) i will line up any XR6 in my Super 6 Commodore and i assure you the XR6 owner will go home with his tail between his legs, the whine is far from irritating it is an awesome sound esp when you wind the boost up.

and Fordie failed to mention the torque figure of the L67 which is 375nm at 2000 rpm and don't forget Holden watered down the performance of this engine so it wouldn't embarrass the V8's in standard tune, remove the cats and add a 10psi pulley even intercool it and run 18psi if you have the balls, the Holden L67 is one of the most underrated performance engines of all time, that can be obtained and modified for stuff all coin.

Thanks, but I dont think that sounds 100% right. I know that an oxygen sensor gives feedback to tell the engine how rich or lean the burn is, so that tells me that a restricted intake just means less air, so the ECU should compensate by injecting less fuel. I think I might stick with my second guess to my original question, seems most likely

scotty20001 did you notice and good increase with the 10psi upgraded pulley
