Max Kms Out Of Tank

[Dr.304]

hey
i have a 1990 VN Calais, and i dont know what the norm is for kms out of a full tank, but i am only getting like 315? What is everyone else getting. If you wouldnt mind, if your car has any mods to help save economy and any tips on how to do it.
I just have a stock 3800, with K&N Panel filter in the standard air box with the front of the air box cut out....
i dunno i thought i would at least get 350 or 370??

thanks

You should be getting a lot more than that. I filled my tank the other day and set the trip meter. I've done a little over 100km, and it's only just under full. When I re-fill it, I'll see what the km's says.

But you should get better economy than that.

yeh im not sure if the trip computer is calibrated properly...any advice on how to maximise fuel economy?

[wayvr]

yeah you should be getting heaps more then that .. how is your driving tho .. if you give your car a hoon all the time then it will be crap but if you just crusing then that ant right but then i can not talk lol i only get 350 to a tank thanks to my engine and exhaust plus extras lol and my driving hahaha

Drive with a lighter foot.

How long since it's had a service?

[Dr.304]

i give her a bit here and there but not too much, i dunno im refilling when the trip computer says i have used about 45 litres, but isnt there 60 litres in the tank? and btw the fuel light comes on....i dont understand..

[Dr.304]

i got a service like 1500 kms ago?! i dont have a heavy foot, im trying to see how many kms i can get max!

[wayvr]

there is still heaps of petrol left in when the warning light comes on put not good idea to run it down that low.. picks up all the crap at the bottom of the tank ... could be a few things that cause it or just how the car is ment to run

what tyoe of drving do you do like highway counrty city ?? cause if you are doing city and urban areas you are stoping and starting alot ....

[Dr.304]

yeh i am stopping and starting alot, my average fuel is 13L/100kms, i dunno whether i should trust the trip computer.
The O2 sensor ill replace and same with the fuel filter but i was reading in the vn owners manual about how to recalibrate the trip computer. I do rely on it becuase when i fill the car up i reset the trip computer and it tells me how many litres ive used...it must be off cause the fuel light comes on at 45 litres used....

It's starting to sound like something wrong with the system that gets the information on your fuel.

While it does make a difference, it should make that much of one. I do mainly city driving.

[wayvr]

that might be noraml for vns??? should see how much it is to get it check out prob wont cost to much if it is bothering you that much thats what i would do

[Dr.304]

vn gal i agree, ill have to recalibrate it according to the owners manual..its annoying cause when i fill her up, it says "470kms until empty" but only lasts upto 310kms...annoying!

[wayvr]

remember your car is like 15 years old or so things start to go wrong with it and that

[Dr.304]

of course its just looking at everyone else they are getting like 380 - 450 kms out of a tank n **** im just frustrated!

[shumway]

id be happy to get 315km to a tank the stroker with 3.9 gears im only getting 280km thats running bp ultimate with nos racing octane booster.A tank of fuel usually cost me about $110 and im using 2 tanks a week,so dont feel bad with 315km

[wayvr]

lol take it easy it is just the pick of the car .. my mate got a vr commodore wagon and every thing that can go wrong has gone wrong and i got a vr to and i give mine hell and nothing has gone wrong not even one drop of oil and that is hard to believe .. best thing to do would get someone to check it out and that wont cost much prob anything and then see what they say and get it fix if you can afford it thats what i would do and i m sure that is what alot of people would do to ..

caltex 98 vortex a good petrol to use ?

[Dr.304]

ill do that...thanks for the advice guys well appreciated.

[wayvr]

no worries post again or pm me if you would not mind .. i m curious to see if it is the trip comp or what is wrong with it cheers

I get about 10L/100km with about 60% Hwy 40% City. Dont rely on the trip computer as it is probably wildly inaccurate after all these years. Do it the old fashioned way and use the odometer on the next fill. If you still come up with 310km per tank then I would look at the oxygen sensor.

I got 680km out of 60ltr's...

530km Average ^_^

Was that on gas or petrol Mat?

I get between 400 and 500 city, and about 750km highway. But mines a 5sp manual so i think i save a bit there.
