Choosing the Right Gas...Help!

Created December 16, 2007, at 7:03 am by Gman1964

Someone told me not to buy regular gas for my '06 HCH, ie., regular gasoline with up to 10% ethanol. I always buy this Regular Gas... but because I am getting such low gas mileage [average 30 mpg], I am beginning to wonder. Anyone up on this?

I would avoid any alcohol blends. We tanked up once with a blend, years ago, and I swore never again. The (carbuerated) car stumbled badly taking off, all the time. Could be things are different, but once bitten...

I don't think going to higher octane will improve your mileage. Higher octane gas's main function is to prevent pre-ignition, which is much more of a factor with high compression engines. None of the regular Honda's currently fall into this category.

Basically, higher octane gas is harder to light. I guess it's perceived as giving better "performance" because cars needing it, cars with high compression engines, tend to be performance models, pushing the limits.

As to your mileage, dunno. Do you do lots of short trips? Do you have the realtime mileage gauge showing? That helps me improve the mileage. There might be some mechanical issue too.
