For me... When I open the gas door on my 95, There is nothing there to remind me of what I should be putting in so it get regular. (And it couldn't be more happier) When I open the gas door on the 01, there's a sticker that says "Premuim Gasoline Only" so that's what she gets. But I also use the logic that Spike uses... Reg is $3.77 Prem is $4.07 $.30 spread 20 gallons cost an extra $6.00. Since I change my own oil and other work Vs the stealership - that savings pays for the upcharge in gas. Just all depends on how you veiw things...

Or are you talking about adjusting the base timing by advancing it?

On a dizzy engine YOU have to retard the ignition timing to adjust for the lower octane fuel, if you dont you will get spark knock (you may not hear it) and as we all know from high school auto shop spark knock over extended time will destroy a engine.
How much you need to retard the ignition timing I have no idea.
Now I will confuse you even more, there were a small number of low compression 3.9's imported to the US, those only require 87 octane, the compression ratio on those engines is 8.35:1 compared to the 9.35:1 on the "high" compression engines.
I do not know how to tell which engine you have.

gas used to be gas. 100% pure gas. no ethanol. ethanol is bad for you engine, but then again, why does the government care when the big-agri corn lobby lines their pockets to force us to use corn-gas? How The Corn Lobby Will Kill Your Older Car | Eric Peters Autos
you can still get pure gas, but you have to look a little harder: Ethanol-free gas stations in the U.S. and Canada

Octane rating has no affect on fuel consumption. The quick and easy explanation is that the higher the octane, the slower the burn. Land Rover engineered and programmed their vehicles to use a slower burning fuel. Their timing is set up for the burn rate of the higher octanes. When you use a lower octane, you get engine knock/pinging. Also called pre-detonation. Not a good thing. The knock sensors then try to adjust the fuel trim and timing advance to compensate, but they are still under the impression that you are running a high octane fuel, and the compensations will only appear to work, but in the meantime you will slowly have issues surface that may or may not send the engine to an early grave. No one has ever done a true comparison to see what happens. So everything you hear is speculation. But in my case, the manufacturer says to use 90+ octane, so I do.

To few and far between.

Was thinking more about this today. My LR3 is the 4.0L V-6 from FORD that was shared with the Explorers, F150's, etc. How similar are the LR V6's to the Exploder V6's? Did Ford have the LR V6's spec'd out differently than the others? Or did LR do some finishing of the base engine assembly after receiving from Ford?
B/c Explorers with this V6 are not specified as needing the premium gas as the LR V6 does.

The only difference that I know of is that LR water proofed the engine.
I didn't think the LR3 V6 required premium fuel, I thought it was regular.
I know the LR3 V8 requires premium, but I do not know your specific answer.
