Fuel Consumption (merged topic)

[Guest Maniac]

Hi all,

I'm really starting to get annoyed with the amount of petrol my car is drinking. I have been doing highway driving and all I get is 300km out of a tank. A mixed traffic/highway driving with an occational squirt will get me 230km MAX out of a FULL TANK!

Is there anything I should check or use to try and fix this problem?

I fill up using Optimax mostly, but BP Ultimate every so often. I don't understand.

Any help would be appreciated.

Cheers,

George

I average about 15ltrs per 100 around town, you have a bad problem unles you are in a highly modified example.

300kms from a full tank on the highway??

What does you instantaneous fuel consumption read when cruising at 100km/h?

Just for reference, I managed a highway stretch last week where I averaged 9.65l/100kms. Around town in heavy traffic I rarely see anything above 15l/100km. Get it checked as assuming you are not extremely excessive on the accelerator, something is NQR.

I thought he might be looking at his instantaneous, but his tank is sucking through pretty quick

I do roughly 60% highway and 40% city on a tank and get on average 500k out of a tank. (3 Tanks per week)

avg fuel is approx 12.6 around town and 10 odd on the hwy.

BTW I always use Optimax and find that it does not give me any extra kays out of a tank than any other fuel.

Sounds like thers a problem there,I get 400k out of a tank putting around town.

I get around 380-400 in city driving and that's running near 300 rwkw's

Something definitely wrong unless your driving like your nick.... :lol:

I get about 360-380 out of a full tank, use optimax or ultimate and do about 50/50 city/highway driving. I also have to travel up a mountain everyday which would use up a little more fuel, but Maniac you have a problem and would get it checked out cause that's pretty bad economy.

Dazza.

I avaeraged 12.8 on dash display and actual 12.2 lt per 100 before K&N and CAI.

it now sits on 11.3 on Dash display and I did 11.2 for last tank which included 200km in Sydney driving and three dyno runs, so hardly driving for economy.

I would get it checked out maybe do a run on a dyno and have a look at the AFR etc

I am absolutely freaked out.

I remember when I first purchased it, on a thrashing it would go on like 12.0L per 100km...maybe 13.0L per 100km.

Now, If I hit it hard, it will go on 21L per 100km....otherwise it will stick on 19.0 / 20.0L.

Have you guys ever used fuel additives?

Eg: Nulan total fuel system cleaner or Octane Boost Pro ?

I haven't though I have had friends who have used these products in their JAP cars and they get better economy and more power.

Whats the feedback - how does our T's handle with these products?
