comment What damage could Gasoline “95E10” do to my Yaris?
I've heard claims that higher ethanol content is not kind to the soft parts in the fuel system...not sure how true that is.

comment Do I really need to use that expensive grade of fuel?
If it's a Chevy Volt, use the premium as it's required (due to the possibility of it sitting for a while before being used up).

comment How long does it take for gas to go bad?
The octane rating is a key factor, too. Premium lasts longer than regular.

@alex I'm sure you can start a fire with the stuff that is old enough to plug up a fuel system, too.

comment How do I safely siphon gas from a tank?
@jmort253 Pulling a fuel line and jumping the fuel pump is quicker, though not as convenient to do at a gas station without a disconnect tool handy.

comment What are the benefits of premium (high octane) petrol?
A Chevy Volt requires premium, since it could take quite a while to go through a tank of gas. Premium takes longer to go stale. Stale gas can be bad news.

On a modern vehicle, something is seriously horked if there is noticeable engine knock. The PCM should tune that away by retarding the timing. Now, an old muscle car craving leaded fuel, that's another deal entirely.

Especially if you have an old muscle car with no powertrain controller / knock sensors.

comment Pros/cons of higher profile tires?
Nowadays the speedometer and odometer are fed by the PCM, which is correcting the signal from the transmission based on the tire circumference and gear ratios the vehicle left the factory with. I guess you're right about the error from tire inflation/wear being comparable to 1 KPH. Still, if it was my vehicle, I'd fix the PCM, or at least keep the paperwork in a safe location to document the change. I don't know of any vehicles where you can edit the current odometer reading by screwing with the PCM. You can change the rate at which miles go on, but you can't take the old ones off.
