Unleaded Fuel Preference?

[T_BONES]

What's everybody's brand of unleaded fuel preference for their Octavia 162 tsi?

I've only ever put in BP Ultimate.

1. BP Ultimate (cleaner, less pinging, most power)
2. Caltex Vortex 98 (happy medium)
3. Shell V-Power (ok, most pinging, least power)

This is from previous multiple dyno runs in my S15 and having a Power FC hand controller to view live stats.

You got pinging with 98 Octane? I would have thought that very unlikely unless there was something way out of adjustment, excess carbon build-up...or something?

He said it was in his S15 (Nissan 200SX/Silvia) so I imagine it was tuned up a fair bit.

Hobbie2k is correct. 250kw@ the rear wheels. With the BP Ultimate...even on a 30 degree day...i could give it everything and was fine. With Shell v-power...the car would cough and splutter and hesitate. So i would drive off boost most of the time until i got rid of that fuel in tank. In replay mode...the power fc shows the ping go through the roof with shell.

Caltex vortex here. Haven't been a fan of BP as I used to track poor efficiency with it in previous cars. Have avoided she'll for a long time as they used benzene to bump up the octane rating. I use vortex diesel as well.

Oh, that was the 'something'.
I knew there had to be one.

good info to know ... any idea if this affects a stock turbo car as much as a tuned car ?

Over the years I have come across bits of information, largely unverified and conflicting, that have just confused me over fuel quality and various claims for performance/efficiency/economy.

When the fuel tanker (probably from Singapore) supplying Adelaide is late then ALL major brands fuel stations start running low/out, then the ship arrives the Shell/Mobile terminal at Port Adelaide and normal service is resumed soon after.
I conclude from that situation that the fuel is coming from one refinery, that the 98 Octane (and others) is the same at all three stated brands, and that it complies with the relevant octane rating.
The exceptions seem to be with the independents that ship in from interstate, usually a bit cheaper and have E10/E85 or whatever. Most mechanics have advised me to avoid those like the plague, which I have and so cannot comment on how good/bad they are.
I believe the fuels sold in Australia and sourced from East Asia contain very high sulphur levels and was a reason that many high performance diesels were not imported here until the refiners brought it down to acceptable levels due to government intervention.

So can anyone point me to an information source that can provide any sort of clarification???
