Is this normal?

crannersEL · 29-01-2006, 10:32 PM

Hey guys, ive only had my P's for about 3 weeks and im noticing how much petrol i use and how often i fill up. I usually put one full tank in it once a week.

Last week i put normal unleaded fuel in her and got 379Km's from the tank.

So this week i decided to put in BP Ultimate, costed an extra $6 for the tank but im investigating whether or not i can get more K's from my tank.

So my question is, is 379Km's for a full tank in an Auto 97 EL Gli 4.0ltre normal or bad??

My car sits in economy all the time also

Thanks Paul

i think that is good, im only getting about 350 from a full tank

InitialD · 29-01-2006, 10:36 PM

400ks per tank is about normal apparently

I get around that normally, but if Im booting it everywhere i get around 350

gthofan · 29-01-2006, 10:38 PM

how u drive it will also effect the economy, ive noticed with highly spirited driving the economy is way down :( but 379k's is quite good for an auto. the real test should be the shell optimax extreme (100 ron) compared to regular unleaded

crannersEL · 29-01-2006, 10:40 PM

So BP Ultimate isnt in the same league as shell optimax? It says better fuel economy when using Ultimate is this true?

Also when you get your licence back Scotty?

gthofan · 29-01-2006, 10:43 PM

bp ultimate is 98ron avaliable everywhere, but optimax extreme is 100ron with 5%ethanol, yes, the magic word, but the closest to us mate, is ferntree gully.
and ive only got 5 days left hoorah, driving legally, i cant wait

PULLY6 · 29-01-2006, 10:43 PM

379 is bad man. I get nearly 500 every time, "highly spirited" driving or no.

crannersEL · 29-01-2006, 10:45 PM

Pully6 what could be causing me to be obtaining such poor figures with the fuel??

-jjM- · 29-01-2006, 10:48 PM

weve had a few threads like this, i remember, some were the same

i guess its prity normal, i know u dont flog ur car at the lights ur prity good, i get around the same, around the mark, been a while since iv filled up lol

gthofan · 29-01-2006, 10:48 PM

one thing to keep in mind.
the area you do most of your driving in makes a hell of a difference.

crannersEL · 29-01-2006, 10:53 PM

I drive to and from work each day which is about 15kms there and back, do abit of cruisen on the weekends, but as Joe mentioned i dont thrash my car so i should be getting more from my tanks. The cars ideling like a dog atm, the car shutters when im sitting at the lights which im guessing isn't too good. I'll have to get a mechanic to look at it because its not really good enough atm.

When i got my exhaust done i was told that the stock cat would hold up and it would be all good with the extractors, and yes the car has lost some power, i dont really push it that hard so i havent noticed it greatly.

5L · 29-01-2006, 10:55 PM

sounds rough, yeh my figures are spirited driving, i get bored otherwise

efgiar · 29-01-2006, 11:00 PM

i get about 600km's to a tank. well i get like 450-490 with just under a quartor left and says i can do another 160 odd km's more. and averages out to about 10.6L per 100km's

gthofan · 29-01-2006, 11:00 PM

hmmm, id keep an eye on the cat, altering the cat t fit the extractors could have loosened the guts and now its beginning to fail, causing back pressure. u may start to hear rattling under the car if it is the problem

crannersEL · 29-01-2006, 11:04 PM

If i cant get more K's from a tank within the next month or so i might have to get rid of the Falcon and buy a small car, i start Uni in a month and thats when i become a poor Uni bum

Psycho Chicken · 29-01-2006, 11:34 PM

Annnnnd the e-series club random diagonosis of the month is a blocked cat converter!

380 odd is low, but not that low. If you're really worried about it, do plugs/filters. Clean out the ISC to see if that helps you idle issue. Then perhaps change the oxygen sensors. For god's sake don't go jumping in the deep end and changing the cat! If the cat is blocked you will know about it.

stay Tuned next week for the return of

O2 Sensor!

Damo · 29-01-2006, 11:37 PM

i get around 350-400 k's from $50, never fill it right up just put $50 in. That's in my EA completly stock. The EB was getting about the same, maybe more like 300-350. So 380 from a full tank is pretty crap, start with the basics as Psycho mentioned.

EDXR6T · 29-01-2006, 11:52 PM

dont sell her cranners just put her o n gas:P

i wouldent hav e clue wut mines getting wen i drive it consistenlly enuff il let u no

gthofan · 29-01-2006, 11:53 PM

yeah paul, just get a quote from steve at auzgas in bayswater, he does some good work. im pretty sure he can do a second hand system cheap

crannersEL · 29-01-2006, 11:54 PM

Ill book it in tomorrow at the mechanic for a check over, even tho it was serviced and tuned about 5 weeks ago. Then ill make a decision on whats next, whether it stays or go's.

I used to get 540-560 when it was stock

crannersEL · 30-01-2006, 12:02 AM

Maybe i need Dandenong Engine Reconditioning to have a look at her, i cant see how anymore than 500k's is possible

As the name suggests they recondition engines... Perhaps you should contact AFF sponsors Jim Mock Motorsport and get your car tuned on the dyno

It is if you drive your car properly and keep it in tune and regularly serviced/maintained... That's just common sense stuff

I took it to Heathcote from Deer Park when it was stock as a rock, did 28 passes and drove home and to and from work for the next two days on a tank of Mobil regular unleaded

Psycho Chicken · 30-01-2006, 12:07 AM

500km is possible. It all depends on where you live and what driving you're doing.

I'm guessing from your location you're doing a fair bit of driving in hilly areas? That won't be helping.

347Stroker · 30-01-2006, 12:18 AM

Fook me, I run a fairly healthy 5.0 in my ute, with a trailer weighing in excess of 1 ton and more commonly referred to as "the parachute" and still get 330 odd k per tank.....

And my driving style would not be referred to as spirited, it would be more like "raping it"
I mean smoking the tyres across intersections with a car trailer and car on the back.....

I'm with Matt. I have to give my 5.0 Ghia a REALLY hard time to get less than 350 a tank.
