My friend has a 92 Deville and it says to put in premium fuel only. Is this true? Could you put 87 in it and will run fine? I asked him but he doesnt know because its really his grandmas car. I know somebody here has one. Does anybody know if people actually put premium fuel in their Deville?

Computer car...87 is fine...he is gaining nothing, but loosing money by throwing better gas in there...the car's computer can sence knocking, or detonation if it arises, and can readjust timing if it happens....tell him to save his cash, and do 87. :)

thanks man. I thought the premium fuel is used by the way the heads are made.

no prob...it actually ahs to do with compression, but that is also told my head design, and cam specs...and timing as well...

Unless it's a turbo/supercharged application, I really don't see the need for engines to get high octane fuel... perhaps if they have super-high compression ?

I asked a Cadillac expert on a Cadillac forum. He said it was the advanced timing it had and there were no knock sensors on it and It could not detect knocking or pinging. You can go in and adjust timing but then you will get lower gas mileage. I would do it and have lower g/m. I sold it so it dont really matter now. But I am getting another one when school starts.

I was thinking of finding a Seville. But having a huge *** Cadillac at 16 hurts the 16 y/o wallet. The insurance and taxes are cheap, but the parts and gas can kill you. But I guess thats what parents are for :D

my family has owned 3 cadillacs. i had a 98 catera that took mid grade but i put the cheap stuff in it, my mom had a 98 seville sls that took premium, and my dad has a 2001 eldorado that takes midgrade. all i have to say is that if it is a northstar engine put in what it recommends those engines arent cheap to repair.

I have seen a cutaway version of a northstar engine. Those engines are bad *** and were made to last.
