VF Series 2 V8 Fuel Consumption

[tml678]

its a massive jump.
thats with a series 1 (6.0) i couldn't see there being to much difference between them tho.

i dunno, i just got out of an L98 VE (non-afm) and it was definitely using less. I would get around 430kms purely urban and easily over 500kms with a mix of urban/freeway. anyhow, like i say hopefully time and a few more kms under its belt might reign it in a bit lol.

There will be if you have a series 1 with AFM active and do a fair amount of part throttle driving - eg freeway

I'm not convinced that's not just advertising.
Totally different car from a totally different era, I know, but our (good condition low km) VS Ecomoo was about 6.5L/100km on cruise-control on the freeway vs ~15L/100km in our usual 'round-the-burbs usage. The VF1 uses about the same 'round-the-burbs.

Since the 6.2 has been around for a few months now, it would be interesting to see what fuel consumption figures people are getting.

My W375 auto is averaging 12.6 / 100 best result over 500kms is 10.0. I'm doing about 65% of driving on the hwy and always run 98RON mostly from a major servo like Caltex or BP. Some of the independent servos fuel is a lower density grade and when I've used it I've noticed consumption increase. Spend a bit more on good premium 98 at the pump & you'll be better off for it. I'm surprised at some of the figures posted in this topic. My VF series 1 SS m6 was averaging about 11.8 so I'm pretty stoked with my series 2 economy

Calais V 6.2lt v8.
after about 1500kms, avg speed 58kms, 12.3l/100kms, 70% hwy / 30% city on 91ron fuel.
Seems as though the trip computer in the vf are more accurate than other commodores I've had.
Have done manual fuel economy calculations from the day I got it, and the numbers work out to within +/- 0.1l/ 100kms.
Hell of alot more accurate than what my vs and vz commodore were.

VF I SSV Ute, 17000 km after one year, average speed 60.7 km/hr, averaging 12.7 litres/100km. Haven't reset the computer from new, using 98 petrol. Fuel consumption is getting lower as the engine loosens up. Last tank did 11.9 litres/100 km.

I am seeing on average around 1-2litres per 100km more since I had the tune and shut the AFM off. Though it could be coz I'm giving it more stick now that it's got more power


People need to take into account that these are near on 2 ton cars with 6.2lt pushrod V8's. They are going to be a bit thirsty.

I used to have an XD 351 which had 149kw when it was stock. I was averaging 33lt per 100km.

I'm now getting 13-14lt in a car with near on 300kw.

My recollection from road test in the 70's was a 302 V8 around 14mpg (20l/ 100Km) and 351 about 11mpg (I think that would be about 25l/ 100Km). I don't have a VFII, but I think the consumption of the V8's are pretty good at least on the highway.

A mate of mine had a 4spd 351C XD, mostly highway usage (Sydney to Wollongong) he was getting about 15L/100km out of it.
EFI is a marvellous thing, try to run a carby 351 at anything like the ~10L/100 you'd get out of a V8 VE or VF under those conditions & you'd be melting pistons ...

My wallet would attest to the 33lt/100km. I think in the old language it was around 8mpg. I wouldn't even see 300km out of an 80 lt tank . I don't want to think what it drank after I put a 780 Holley on it :unsure:
