The manual says use premium, but that regular can be used without
damaging the engine. That's what the manual for my 94 says, anyway.

I'd think you could easily go to the dealer and ask to see a manual. I
never buy a car without reading the owner's manual, just to see about
things like that.

The Lincoln Town Cars have always used "regular" unleaded. The issue with
the LS430 is now you're getting a high performance engine with advanced
ignition timing and a higher compression ratio.

Penny-wise and pound foolish; stepping over dollars to pick up dimes. If
you cannot afford the small percentage difference in the price of the
gasoline, you sure as hell can't afford the car! There's a difference
between frugality and stupidity.

and yes, you -can- put 87 octane regular in the tank, but I sure wouldn't
and IMO only a schmuck would. The dealer will tell you "only in an
emergency". The newer engines can automatically adjust (retard) the
ignition timing so you won't experience any damage from spark knock, but
engine performace will sure suffer.

But more importantly, does the manufacturer specify that 87 octane fuel
can be used without causing damage to the engine or voiding the warranty?

Yes.

So it won't damage the car, right?

All that suffers is engine performance, correct?

Therefore, why would only a "schmuck" put regular in if the only
difference is a bit of engine performance?

This reply is just ... well, I will be kind. If the car does not exhibit
any signs of knocking, you are just fine. MPG may suffer a little. 

My father once told me ..."The cheapest thing you put in the car is
the gas" .... I agree .... give it what it wants or buy a Camry.

My microwave says don't put any metal inside... it is easier to make blanket
statements than try to explains the details to the masses.

Not in the owner's manual. The owner's manual clearly specifies
"Premium".
