  1. This is a good wrap up of the situation we are in at the moment. 66th in the world for fuel quality... Straya. https://www.theguardian.com/environment/2019/nov/16/wrong-turn-why-australias-vehicle-emissions-are-rising?CMP=Share_iOSApp_Other
  2. I’m not angry, just disappointed ☹️
  3. To see if there is an actual practical and useful difference - as opposed to a technical difference on paper. Does RS tuner test a sample for its octane number I wonder? meh. Petrol and internal combustion needs to be killed off anyway... Even if we did drag our fuel quality out of third world standards it’s still a shitty way of propelling a car....
  4. Never ever cheap out on Shiraz!! My god man, were not savages... Never said they were the same - the additive packs on the proprietary blends will alone make some change to the way they operate (not always for the better as you note). I’m just saying they’re not worth it, and very few cars (such as yours) even need it. If it’s 96 octane that’s still a difference you’ll see on a computer log, but not convinced it’s worth the dollars - especially if you paid for 98. And maybe some retailers are closer to 98 and if you’re tuned for it you’ll a difference. Stock road cars are not generally that sensitive and don’t see an advantage with fuels beyond what they’ve been mapped for. Would be fun to some blind butt dyno testing Get your missus to randomly choose a grade to fill up with and not tell you.
  5. I’m not exactly sure, I’d be inclined to write to them and ask them how that works and if there is a more recent study... Averaged results like that can have all manner of stories buried in them... Maybe they’re dumping 98 in the 95 bucket, maybe a few 91 pumps had been filled with 95 like our friend mentioned. Dunno. It certainly doesn’t help with 98 pumps specifically were tested at... Sorry, that’s all I got - I’m working off pers comms so you’ll have to make your own call on it. I’m a cynic about the marketing and mark up on “proprietary fuels” that are unregulated for any claims above 95 and the manufacturer of my cars spent millions on tuning my engine for the base 95. That’s good enough for me.
  6. Not specifically - I didn't ask for proof, I just know he knows what he is talking about. Sorry, like I said the lack of a standard is the main one for me. https://www.legislation.gov.au/Details/F2019L00455 This may well be a Mexican standoff of pers comms with out industry friend There is this from some time ago, wonder if its been done more recently - but back then there were some failures to comply. Cant see here though if 98 is tested to 98 or 95 standards though, or if its tested at all. It might not for a statutory test like this, they test to the standards and with no standard for 98... https://www.environment.gov.au/protection/fuel-quality/compliance/monitoring/national-fuel-sampling-programme
  7. Sorry, no can do on the name etc on a public forum without his ok. That’s fine, just relaying what I heard - make up your own mind. For me the lack of a standard is good enough for me to apply some cynicism about what is a heavily marketed and marked up product as opposed to what they’re legally required to provide. If you’re happy to accept the marketing at face value no worries. 95 is the minimum grade fuel in many countries (we are unusual in still having shitty 91 grade...) so it’s mandated that is be provided. It’s a very very very small number of specialist cars “required” to run 98 (some STis I think?) but to meet the needs of “consumers” 95 is it - and hence regulated. 98 is just a “premium” product designed to make more money. I wonder if our industry friend can say what the profit margin is on each grade? There are statutory penalties I believe for failing to meet 91 and 95, but for 98 it only needs to meet the requirements of 95 legally speaking. As I understand it anyway - if anyone has a better familiarity with the Fuel Quality Standards Act 2000 and wants to correct me than I’m all ears. For me - 98 never presented any improvements in cars I’ve used and I’m ok using the fuel it was designed to use.
  8. Sorry, what did I miss? I thought you were being pretty aggro, I was just curious as to what the reason for your somewhat abrupt assertion was... Thought I asked nicely...? Still not seeing anything that supports your claim though? Any publicly available reports from independent testing of fuel from retail sources?
  9. Righto. What industry is that? Care to share testing results?
  10. Also worth noting that there is a Determination (technical standards) under the Australian Fuel Quality Standards that provides the standard for 91 and 95 octane fuel that suppliers are legally obliged to meet. There is no standard for 98 and it’s left to commercial interests - how much do trust oil companies to provide products as advertised?
  11. I believe so. Variations of course as well but more like what is written on the tin. There are a handful of suppliers and the premium stuff I think all comes in from Singapore (I think... A lot of our fuel does I know for sure though), the only differences is that the different retailers drop i their own additives. Back in the day when I had carburettors and points ignition, I could “tune” it for the different fuel grades (unleaded or super) but these days just look at the label, find a servo without crap in their tanks and enjoy. Be more concerned with the disgusting levels of sulphur and the lack of Euro 6 and 6B engines available here... And the lack of a co2 emissions standard (we are the only country in the OECD without one) for new cars that would have saved the public billions in reduced fuel costs but was shelved after lobbying from car importers who feared less profits from selling old school engined cars
  12. Know someone involved in fuel testing, and it turns out most 98 in Australia is very rarely 98c - usually 94-96 at best. Save your money, just use 95. Alfa 1.4 Multiair turbo and the very highly strung Clio 0.9 3 pot turbo couldn’t care less if it was 95 or 98. No difference at all. Use the minimum rated, don’t get contaminated fuel and call it a day. The engine engineers spend a lot of time and money making it behave on the rated fuel, and anything else the ecu will do for protection (that’s an annoying trick Subaru does not reverting to normal after a bad fuel event!). You have to remember that all grades of fuel contain the same energy - it’s only the resistance to self ignition that differs, so any changes are dependant on the engine design. If the engine’s map has been held back for 95 with the deliberately designed ability to advance more with 98, rock and roll. But I’d love to see that written down from someone from Renault or a timing light out on a car on a dyno with controlled tests with both grades...
  13. And learn the language of the ACCC and Australian Consumer laws.
