Premium Fuel
#2
Sorry break the bad news to you, but yes it's necessary. If you look in the owners' manual it tells you the minimum octane rating your engine is designed for. The good news is that I've personally noticed a slight improvement in mileage when I fill it with premium as opposed to mid-grade. It probably about evens out.
Land Rovers are famous for many things, but fuel economy is not one of them.

In the week to 10 days after Hurricane Sandy struck, the only option was to buy regular gas. They weren't trucking in any premium.
Over that week or so, I did not notice any engine knock or anything adverse/rough, however the fuel economy was noticeably poor. As has been mentioned, it all evens out.

20gallons/week * .20/gallon over regular = $4.
Figure $4/week * 52 weeks = $208/year
Now, I'm as frugal as they come, to the point of pissing off SWMBO. (I buy my Polo shirts at the Goodwill resale store, which are $1 more than non-Polo brand shirts and I wait until the 50% off days - like today - to get them for $3.50!). Even I spring for the premium without hesitation since it costs so little to avoid any downside.

For the purposes of this discussion, let's assume you get an extra 1/2 mile per gallon by using premium gasoline. National average for gas right now is $3.746, in the USA according to AAA. Thus:
20 gallons/week * 1/2 mile further per gallon = 10 extra miles
Land Rovers average somewhere around 15 mpg, so ten miles is equivalent to 2/3 of a gallon
$3.746 * .666 = $2.494, multiply by 52 weeks = $129.68
Subtract the difference, $208 - $129.68, and you're actually spending $78.32 per year. (By going 10 miles further on the same amount of gas.)
*Actual mileage may vary, price of gasoline will, in fact, vary greatly by location and is subject to the whims of oil future speculators, results not valid in Canada or Hackensack, New Jersey.
