VF Series 2 V8 Fuel Consumption

[Hq King]

Pollutey in another way: E10 and E85 both generate more carbon on short trips than higher octane fuels. It may have a "higher" octane rating, but that doesn't mean it will provide improved economy. E10 and E85 is virtually sugar cane with ethanol added — I don't know what the attraction is, and for what it's worth, you won't find either "fuels" in outback Australia, only LPG, diesel, 91, 95 and 98, with progressively higher (stagnant) prices for each

Extremely hard to get e 85 in nz and expensive but some real gains to be had for forced induction and engines built to suit but 98 is what I put in mostly

Are you sure it’s less pollutey? It’s theoretically more sustainable because that 10% ethanol isn’t made out of dinosaurs that aren’t coming back; but given you use >10% more of it than 98 & our current ethanol production methods burn fossil fuels, I dunno that it’s actually less pollutey ...

OK you forced me to use Wiki , make up your own mind https://en.wikipedia.org/wiki/Ethanol#Engine_fuel
EDIT : OK now i read it i "could be wrong" on some aspects

... If I’m gonna have a 1.8T 6L V8 car, I guess that’s a bit irrelephant...

Yep, it's truely irrelevant discussing old tech LS3 and fuel consumption in the same breath. Token AFM improvements in the 6lt doesn't count in the big scheme...

It's especially irrelevant when modern tech allows you to just as easily be stuck in stop/start traffic and still get 4ltr/100kms

Sometimes, reading parts of this thread could be similar to the discussion within a room full of obese people talking about their favorite foods

I'm more concerned with fuel going off.

That’s my concern too. I use this stuff as a result. Keeps the juice fresh for 12mths:

1/16 build manual VFSS never reset the fuel since new 8500kms now fuel average at 12.5 at 43kms/h avg, tuned at 3000kms with full exhaust and otr.

I dont watch fuel economy much but have noticed how much better it is when you dont let engine labour in 6th and 5th when in hilly areas

Going for a long road trip down south next week, this should see my fuel consumption drop down to around 10L/100km lol

5 year average is 15.2 mpg however I'm not light on the accelerator! btw, 2015 VF with LS3, manual

I track fuel usage every time I drive. This allows me to tweak how I drive. It aslo helps me dial in the custom tune.
Fuel consumption is directly proportional to average speed, and whether you thrash it off the line often.
A graph that I have created, tells me whether I am being economical or heavy footed.
Fuel around town @ 40kmph gives about 14.5l/100km
Highway, dead flat road instantaneous fuel 7.0l/100km.
Trip average 10ish depending on how hilly it is.

What app is that?

Also, Auto ls3. When I drive, I average 17/100. Don't do much Highway.
