I tried mine with 89 & 93 octane...
to tell u the truth...I don't see any big difference...
But some oil company said ur engine will be cleaner if u use higher octane gas.
Personally, I think 89 octane is good enough...
Just found this fm my honda's owner's manual
"Unleaded gasoline, pump octane # 86 or higher".
Y pay extra for premium gas?? |
