with the price of fuel i have taken particular note of milage recently.
It seems in the last couple of months (i exclesively use shell fuel) that efficency has dropped by at least 10-15% .
does anyone know if now shell is being rebranded "Z" if they have changed the fuel blend and are now pumping biofuel.
i have had the same results on 3 vehicles so it has nothing to do with tuning ect.

shell used to be the worst crap lets hope they change the fuel. Try caltex that fuel has the best punch in my opinion for my cars.

Wealman.thing is it has SUDDENLY dropped .just happens to coincide with rebranding excercise.susppicious eh
EG motorcycle was 52MPG now 44 MPG.notheing else changed .i use the motorcycle example becasue its a small tank so real easy to keep a check on ie fill exactly the same each time.

My falcon runs mint on 91 but runs like ass on 95 or 98 bp branding and shell. Whats up with that!

I think maybe it's the switch from summer fuel to winter fuel, have you tried filling up at non-shell service stations and extensively recorded results there too!

Ill agree with that on most engines, but i have noticed that Mobil's 98 is VERY good for Turbo engines, I prefer to use it even on my cars when i can get it

Nope its about the name change fish, but in saying that 95 is much better. Always run it in pretty much anything unless its designed for 91. But watch your speed if you decide to flog it.

Ok mate will do, Always have run my cars on 95 but it was shit when I tried it. Will put a few tank fulls through and see how I go. Cheers.

Yup but watch your speed.

The Falcons have a self learning thing in the ECU which would of learned to run 91. As melissa said if ya run it for a while it will re-learn and will get better with the higher octane . or you could just Reset it if your near a Ford Dealer, would only take them no more then 5 mins to do

How can this fuel be so bad , its all the samejust with their own octane booster in ( which is probably the same ). Refined at Marsden Point . Gull is only 1 imported direct now , Challenge (importeddirect )was a good fuel but is now Caltex.Believechecks are carried outperiodically on its quality .I run my M328 on shell & have occasionally tried BP &Caltexwith no discernible difference in economy or performance

I road tested all the fuels some years ago, found Shell 96 (5) was best for my engine. I am still using fuel I bought a month ago with a 20c voucher. I fill the tank and a 20ltr container, normally around 85-90 litres. It'll be interesting to check this new stuff! Who reckons the 'Z' logo looks like an 8!
