[Euro] Fuel Consumption

Shell Extreme 100 is more expensive than 98RON yeah? Shouldnt it be cheaper than 98RON since it has Ethanol in it?

Seems like Shell are taking us for a ride :eek:

You hit it on the head and that's why I refuse to buy it. The IFS 95RON E10 fuels are 2c/ltr cheaper than normal 91RON fuel which is the way it's meant to be.

yup.. ethanol is meant to lower fuel cost..
but shell used it to riase RON level as a marketing weapon.

I wouldn't mind using the Shell Optimax Extreme 100RON if it was only 10c above normal 95 premium unleaded.

But its a massive 17c hike on top. As everyone noted, ethanol is cheaper, less dense, less mileage. But higher Octane (which also drops quicker).

There's actually one fuel I have never used yet but I should try, and that is the Mobil Synergy 6000 (96 Ron). I wonder if I'm wasting money using the 98Ron 8000!

Update, consumption improvement

Model: Euro 6Spd Manual
Mods that could impact consumption: VAFCii, K&N Typhoon CAI, ZORST, Tyres, Rims
Kms: 48,500kms
Highway kms = 280++ Kms
City Kms = 120+km

Used 31 Litres to travel 410 Kms

Average Consumption over this period: 7.56L

lol my euro hates 95RON fuel (tried Caltex this time), I used high gears and everything, the best I could get is 9.8L/100km (avg 10.5L/100km). Plus I definetely noticed a bit of a performance drop.
Just filled up with Vortex 98 yesterday, easily got it down to 8.6L/100km on suburban roads. (avg 9.2L/100km, and 6.5L/100km on the freeway@100km/h in 6th).

No more 95RON for me...

*laughs* I've filled up with BP ultimate since day-one from the dealer and my dealer still thought charging $15 for fuel-injector cleaner was kocher. Bastard.

So either BP ultimate doens't burn that clean or the dealer's full of crock.

Getting more 10.0L per 100km with a mix of peak-hour and non-peak traffic. I think they may have slightly overfilled my oil at my 5000km service which may also impart some higher fuel consumption levels?

I seem to remember reading somewhere in the owner's manual not to put any additives in the fuel. Your dealer is just getting a nice mark up on the fuel additive IF he put it in? BP guarantee the cleanliness of their fuel.

I'm the same as you Eurodude. I tried Caltex 95RON for three tanks and all three were in the 11's. Apart from those three tanks for the other 15000klm's I've used Mobil Synergy 8000 and my average is 10l/100klm. It's an auto as well.

hms not a fan of Mobil Synergy 8000, it gives me bad fuel consumption compared to the other 98RON brands (bp+caltex).

Quick update for the Auto Tranny users as well.

Last fill up i managed 7.6L/100km and the one before that was 8.5L/100km. ULtimate is so much better.

Went to the airport 4 times so maybe thats why.

Stop Go traffic when i was using Optimax was piss weak at 12.9L/100km even.

Bump: Synergy 8000 is now available on the Gold Coast. I filled up with a tank a couple weeks ago and found it the crappest 98RON fuel out there. Fuel economy was down about 40-50km's per tank, power delivery was down and vtec made a really odd noise. Back to BP/IFS for me. I filled up with 95RON BP the tank after and it's back to normal.
