Unleaded Fuel Preference?

I think you should all get a life and stop playing with your "willys" 98 is 98. It all comes from the same place and a petro-chemist would be flat out telling the difference.

Thanks for the constructive post. If people notice a difference, they notice a difference. It's probably more to do with the age and actual servo than the fuel. I also tend to avoid filling up if the tanker is there.

Average consumption over 154,000km = 6.7L/100km

That's excellent figures for a "tuned" saloon car Brad.
I'm only averaging 8.7 over 19,000kms in our Superb but that's with DSG and at least 80% city/suburbs driving. I suppose it's about 250kg heavier than the Octavia also..

75% of my driving is on the motorway in reasonably free-flowing traffic. The commute is so monotonous and heavily policed (I pass at least 4 HWP cars per day) that I make a game of trying to achieve maximum economy... and seeing how fast I can take the Narellan Rd/HumeHwy cloverleaf. My best "end of motorway" economy so far is 4.7L/100km. My best cloverleaf speed is 80kph. I could probably go quicker but a mate wrote of his car on the same corner when he had to swerve around some debris - it's always nice to have a buffer.

While the fuel may all be the same base and come from the same refinery, the additive packs are different. As one of the others said, Shell adds more benzene to increase the octane. There have also been significant changes to V-Power (and whatever Shell called it before that) over the years. Many motorcycles couldn't run V-Power when it first came out.

I think shell were forced to drop the benzene quite a while back, but I had stopped using it long before that due to the potential problems it can cause both mechanically and environmentally.

So much information and constructive posts to take onboard, awesome stuff. I've always been led to believe to steer away from servos in low lying areas after heavy rain or what Dzl_Dubba just mentioned in regards to not filing up when the tanker is there as it can stir up the sediment lying on the bottom of the tanks.

On a related note, what diesel do folks on here prefer? This being my first diesel car, I'm inclined to use Vortex (was my preferred 9, but would be keen to hear other people's views.

I already mentioned that one

I use the Vortex stuff as diesel is dirty already and anything with a higher grade can't be bad.
