    You know the funny thing is at this point my MAZDA is the slowest of all my cars. Everything else is either BLOWN or TURBO CHARGED...I even have a PT Cruiser that will do 0-60mph in about 6 seconds. LOL The MAZDA does not even handle half as good as two of my other cars .They are MINI's But hey my sound system in the MAZDA keeps me enjoying every trip I do in with it long or short.
    I have a Z06 and everyone one those pages always talk about how they had a run in Mexico last night...yet some live more than 1000 miles away from Mexico... it's all legal in Mexico...LOL

    No scientific analysis here, but after testing both 93 and 87 octane in my new GTR, I feel no difference whatsoever in daily driving. I can cruise at 75-80 on the highway and still easily accelerate to pass someone as needed. It runs as smooth and has the same feeling of pep off the line, regardless of which fuel I used. Looks like 87 going forward for me......

    2.5T's power curves with 93 and 87 AKI gasolines published by Mazda prove exactly the same thing. "To prevent unnecessary spending on premium fuel, both power ratings are published".

    That's a HUGE advantage the 2.5T has over most other makers' turbos.

    For now my wife is under strict orders to use 92(the highest available in my region). Over time we may switch to 87 or 89. She drives easy and I drive for fun😁

    Iíve using the Costco premium gas here in Ontario Canada. I havenít put regular gas in it yet since owning it only at just under 2k km on odometer. Costco sells premium for the same price as reg at other gas stations so it makes sense as I live 1.5km from it. Loving this ride so far!

    Not sure if because my car is still fairly new with 800 miles but I switched to 92 to try it out and my mpg went down even though my driving habits stayed the same compared to using 87. I'll stick with 87 for now as I didn't notice anything different from 92 except worse gas mileage.
