Regular Gas?

leepeen · 06-02-2009, 12:22 AM

When i picked up my 370z at the dealership, they've also filled my Z's tank with 89

octane gas, eventhough the minimum recommendation for octane usage is 91.

However, i don't think it damaged my engine at all, but i can ensure you that when you

fill your Z's tank with 91 octane, you can feel minor improvement compare to 89.(only if

you are extreamly sensitive person.)Personally, i put premium gas(94octane) everytime i

fill my Z's tank, and i can feel way better power than 89 octane. Occasionally, i put

Lucas octane booster with premium gas(94), which it might be raise the octane number

up to 98(approxi), and it makes me think that i've moded my Z

eventhough it's 100% stock. Just opinion
