does this sound right ? ( fuel consumption)

there is something wrong here! fully loaded car shouldn't make it labor, Ive towed a vq statesman with a vs exc v6 on a trailer and it didn't relay labor, i knew it was there but had plenty of power to pull it. 5 people in the car shouldn't be noticeable.

is your fuel gauge accurate? my vr 2 wagon gauge is all over the place down the lower end of the tank, which is what all my vr's and the olds vs do.

80km is only 40km less than the half of the fuel you used to get 240 out of 30L if you get what im saying

 

Sounds about right. My car runs great but even with my lard ass 120kg Cousin its noticeable, 0-100 probly adds an extra 1-2secs. Drivin around town startn n stoppin with that much weight would do it. Plus doesnt really sound like the car had enough time to adjust to 95 octane to get any economy benefit, but i may be wrong there. 1st Gear is horrible on fuel. I have one hill on my regular drive that by doin 90 i use 15% less fuel than at 70k, you really need to average over time to get an answer on how economic your car is. Temperature also effects it a fair bit, I find in summer i use nearly 20% less fuel cause car is running leaner and doesnt take as long to heat up for short trips

 

i only got about 430 to 450 km out of a full tank and that's city drive top speed of 70kmh with a stuffed engine that had oil problems

 

does this sound right?

yes but no
which 95 octane did you buy.
use only the big 4 95 Octane (BP, Mobil, Shell & Caltex ) cause the other crap stations pump out **** and alot of them with water or ethanol with the petrol.
I only run on 95 and get the same kays roughly under all conditions.
if i now put in 91 unleaded i will get 80kms less out of a tank. No S**t
95 is smoother and you definately get that bit more power, ie instantly no hesitation.
Dont why it would be labouring then, like moffman said somethig else might be wrong.....

 

i put about 17 litres of 95 in and get about 120 ks around localtraffic lights and stuff and i give t to the car andi got ***ed lifters an i had 2 ppl in the car and that ethanol crap it really isnt worth getting at al its cheaper but you use twice as much and y car gos like crap on it

 

my fuel consuption is unbeilable barely 250km for 60ish litres not very happy gonna get new injectors and hopefully that will fix cause im pretty sure the little o rings on my injectors aint sealing properly and they look horrible

 

God with those poor economy figures i'd be either checking and/or replacing your camshaft sensors, get an efi tune or seriously be looking at your auto's and change your driving habits. I've got a VS-II Esteem and driving it normally gives us a good 10KPL+ and that's in varied loads/driving. We've got lots of country/highways and sharp corners that go for many K's. When we put in 20 litres of fuel, we easily do well over 200K's on it. We test it time and time again, and we're really amazed by the economy on her. She's got 230,000K's on the clock and hasn't had a major service in some time but still drives real well and delivers good performance.

regards!

 

dont have an auto haha all sensor have just been replaced and the engine has only done 160000 kms ill let you know how it goes after i change the injectors though my dad had the same problem and after changing them fuel economy went back up to around 700 kms a tank

 

I get 200 from half a tank and about 430 full Locally, 650 on freeway

but I think my oxygen sensor is buggered because its over fueling

 

Yeh I just reset my electronic fuel consumption each time I fill up and then watch that number climb to know when it is time to fill up again as the fuel gauge tends to be a bit all over the place

 

Im trying to figure out why my VR goes through 60L in 300KMs.. Should i look at fuel injectors and oxygen sensor like these guys?

 

yes you should because I get 500kms out of my tank and I use 91 fuel

 

4 people in a car you are deffinaly going to notice it. I mean fully grown blokes would be an average of say 85-90kg each? include urself and u have an in car weight of like nearly half a tonne. So to say having people in a car shouldnt make any difference is a load. As for the fuel, check your zorst for black soot, give the inside a clean and then drive it for a day or 2. If its all sooty again and you know its not burning oil then its unburnt fuel and its O2 sensor time. My VR O2 sensor was rooted and the chrome tip would turn solid painted black within 4 days

 

best i have gotten from a full tank of 95 unleaded was 380km's. driving as lightly as possible.

 

I'm lucky to get over 350k's to a full tank.

Usually around 300k's in flat out chokkas bumper to bumper city traffic.

 

i get 480k's out of a full tank city driving

 

Well what the hell an I doing wrong?

No error codes. Might have to clean the MAF.

 

A car under load always uses way more fuel than a car cruising. even if you're light on the foot, stopping and starting is gonna kill your economy, you need long stretches of cruising.
