Eighth generation Civics are the 2006 and later models.
As for what premium fuel will do to the engine, the jury is still out on this particular design, however, as a general rule, extra deposits will occur from consistent usage of fuel that is higher than the recommended AKI rating for any given engine.
Regarding fuel impurities, I'm not sure what you're getting at here.

to back up shipo, my (admittedly limited) understanding is that the primary difference between regular and premium fuels is only the level of octane in it. Think of it as having two barrels of regular fuel, then adding an octane booster to the one you're gonna call premium. No difference in processing and levels of impurities. It's just that higher-compression engines require a higher octane in the fuel.
for my take, i do recognize that there are (sometimes) some notable differences between certain brands of fuel. Such as how each company mixes their fuels, incl. detergents and other addatives they might use. I've found and use a certain local station that consistently has lower (-ish) prices, but also has a reputation for a better fuel mix, which I have also seen in my car's performance.
For your comparison, I have an '07 Si, and driving around normally (about 60/40 hwy/city), I get between 31-32 mpg pretty consistently. On solid highway drives, I'm up to about 35, and strictly city (or more "spirited" driving than normal) I get about 29. I've got ~7800 miles (over ~6 months), and have tracked my mileage pretty carefully over that time period.
#154 of 158 '07 Civic alarm silent activation?

Pretty simple. Just hit the remote lock button one time and the lights will flash (visual confirmation) letting you know that it is locked. If you hit it a second time (within a few seconds) it will give you the audible (horn) confirmation. You can also hit the power lock button when exiting the vehicle and the alarm will set automatically ( you will not get lights or horn). This is also the case if you use the key in the door to lock the vehicle. Make sense?
#156 of 158 Fuel Gauge
Dec 04, 2008 (5:16 pm)
The fuel gauge in my 2007 Civic always stays on 100% for much longer than expected after filling up the tank. Does anyone have any insight into how the fuel level is measured? Is the scale non-linear, or is it simple clipped at the ends (or both)? How many gallons are above the full mark, and how many below the empty mark (assuming the car is on a level surface)?

almost all gas tanks are very non-linear at the min and max, the geometries of the tank cause that. It is very common for fuel in the neck to cause the gage to indicate full for quite some time.
On my 07 I estimate that I have a couple of gallons when the low indicator light appears, altho it might give you a most exact answer in the owners' manual.
The easiest way to determine a more exact number would be to note how many 'bars' are left on the gage before you refill, and corelate this to the # of gallons it then takes to fill it. Over time you'll have a good idea of what each bar on the gage truly indicates.
#158 of 158 07 chugs and stalls

I have a manual trans and the car chugs and stalls when idling. It gets bad when the cars fan kicks in otherwise it is fine.
