After a trip from
Canberra to Parkes returning via the Blue Mountains and south coast i am now totallyamazed in the difference in performance in fuels. I used to use Woolworths diesel because I could get plenty of 4 cent vouchers. Then Coles &
Shell got into discounting and I now use
Shell. I have to my amazement discovered that the
Shell gives me far more power that I can only measure by throttle position and an increase in economy that is stagering.. with woolies I could get an average of around 5-7 km / litre with
Shell im getting around 8-9 km/litre. Both of these while towing my Van. Maybe despite woolies claims their fuel is somehow inferior or contains ethanol.. I just dont know ... maybe someone on the
forum has some inside knowledge.

I also use
shell, and have noticed FAR better fuel economy with it, costs more, but who cares, car is happier, wallet is fatter.
YMMV

I find it costs about the same...plus I get a double whamy with "award" points... buy on my plastic card & flash the flybuys.. so many points that for my trip to FNQ in June I have so many points that I'm gonna trade them for a
Caltex card.... I'm still curious as to why it makes such a difference.

After using
Ampol (
caltex) diesel I must say there is a difference. I notice it with the amount of smoke I pollute the atmosphere with!
Ampol is cheap and half way between work and
home (with no other fuel stops in my 45min drive!!) so it is always easy to go there, however after a few weeks of filling up there I start producing lots'o smoke. Go back to BP for a few tanks and whamo she barley puffs at all... you gotta wonder... I had not used
shell because of a bad experience running my bike on their "premium" which was just total crap. But if there diesel is good, might be worth a try!

I totally agree. I have been using the same discount petrol station for years now and have noticed a drop in performance, and consequently ks per tank on standard unleaded, since Woolworths and
Shell started discounting. I get the same poor performance from
Caltex, but good results from
Shell ULP and Optimax and BP.
Isn't there some government body that govern the quality of fuel?

Yep ... I agree. I started using Woolies for petrol in December last year after using BP exclusively for the previous 2 years.
The difference came about gradually, to the point where my petrol Jack was beaten off the mark by Tdi Disco. Not trying to discredit the Disco, but something was drastically wrong with my vehicle.
Ran fuel injector cleaner concentrate through the system, started filling up with
Shell or BP (depending on the day's price) and over the next few fills, the perfomance improvement was there. I'm now looking for a rematch with that Disco.

After my original post I've been doing some research.
Shell,
Caltex & BP have tech data sheets that I downloaded. Wool worths have yet to answer my query..."is there any ethanol in woolworths petrol or diesel".
Caltex states quite clearly that they sell ethanol blends thru Bogas and BP and
Shell also sell blends but they are clearly labled. Phoned my diesel mech who says that Ethanol in diesel in very small amounts 0.01% is benificial re algae but in larger doses does cause loss of power and corrosion.

I have used Safeway & other discount voucher fuels in 2.5td Triton & recently tried
Shell. The motor seems noisier, more clatter all the time around town but it is going
well & economy is good so maybe its putting out more KW's.

you'll find the poor performing fuel has a low API, which is a measure of the useable energy in the fuel. Diesels are particulary sensitive to the energy level in the fuel. In Australia, we traditionally run crappier fuel than what the engines were designed for. As a rule,
Shell Mobil, and BP, were all pretty good with BP usually setting the standard. Wouldn't touch discounted fuel servo's or many of the supermarkets if you broke both my arms. Never had much success with them. As to the contents of the fuel, I'd be interested to learn more as
well
Cheers

I always thought fuel came from the same place but judging from these posts maybe not. I was comuting between Kalgoorlie and leinster for work (800k roubnd trip) and filling up both tanks to take advantage of woolies cheap fuel in Kal (dont need to fill up in leinster) and my wagon has been smoking like that tassie polly . The most likly reason is injectors but now coles has got on board with
shell in this Wait Awhile state with the cheap fuel I will give it a go on my
Easter sojurn this arvo (
Thomas river 120k east of
Esperance)

I thought in WA everything came from the sole (BP) refinery in Kwinana, just re-branded, with the exception of some imported stuff which the independants sell.

Funny how different vehicles respond to different fuels.I have used Woolies fuel often in my TD Jackeroo and found it way down on power and economy,wont be using it any more.Mobil down on power but good economy.Caltex,good power and economy and
Shell ,good power and economy 9.4l/100k so I guess fuels aint fuels.
