Welcome to Just Commodores, a site specifically designed for all people who share the same passion as yourself.
This is based on US fuel. Fuel in Australia is of less quality than the most developed countries overseas. I have tested a number of fuels over the last 15 years. I race and have tested various fuels in my racer and in my various DD cars over the years. Of all the fuel available in Adelaide at the time i found that Vortex had the best economy, as much as 10% above some 91s. I tested by filling to the top of the neck and drving 200km. I did this over a number of months and each time Vortex came out in top. 98 was the best but economy wise it was pretty much on par with Vortex 95, only marginally better. The cars i tested this in were not tuned for 95 or 98. One was a Jeep that no one can even tune using the stock ECM. The fuel thing has been debated 100s of times across 100s of forums and few people end up agreeing. I trust my testing over some mob who is going out of their way to disprove something. The issue with Aust fuel over other countries is the filtering, we simply don't get clean enough fuel in our 91. My bro in law blows out yellow - brown sludge from choked up fuel filters from customers that think like most, that all fuel is the same..... He was the one that opened my eyes. He told me BP is the best but i used the fuel that i get the best economy and is cleaner than the cheaper alternatives.Premium gas vs. regular: What's really better for your car? (CBC Marketplace)
