I apologize for asking this in an Insight forum, but I can't find a Civic Hybrid forum to ask this and I figured you Insight guys would probably have an answer... (I also searched but didn't see this addressed directly)
I bought a 2005 Civic Hybrid in late November and was getting 47 mpg on "regular" grade gas (86 octane).
I was curious what kind of difference a higher octane might produce since the Civic Hybrid has a high-compression engine so I put tank number three in with 88 octane.
I'm now showing 54.1 mpg with 210 miles so far on this tank. This is higher than the EPA rating which is surprising to me. Also, I'm not babying the car and am actually speeding a bit (mostly highway for that 210 miles and 65-70 mph). These are round trips too so it's not like I've just been driving down hill.
So I was wondering, have you guys experimented with higher octane to help mileage? Does the Insight use a high-compression engine where the octane might allow the engine to develop more power and get better mileage? Anyone else seen this dramatic of a difference by upping the gas a grade?
