Yeah, the transverse mounted radio and the propensity to rust made it a true classic. That's the car I learned to drive in.

GM is hit or miss same with Ford but Chrysler consistently puts out garbage.

^^ this, that's not a car you can drive to work even if you could afford it. The Fuel is going to take 97 or better heck it might need rocket fuel with those combustion levels.

If it has a decent engine management system the type of fuel doesn't matter. Of course seeing as Dodge thinks it's okay to use a cast-iron block and forged parts on a high-end engine all bets are off.

they said something about running 1500 psi, that's going to require a high octane burning level. I could look up the exact compression ratio and tell ya what it will require but I don't really care THAT much. Off the top of my head it'll need at least 97 I'd be surprised if it runs on 91 and would bet my left hand it won't run on 87.

Im not putting anything in a car like that.. There's other things Id rather buy than fuel for a car that'll suck your wallet dry..

My car is second hand but i live very comfy

correct but psi levels don't fluctuate that much between normal operating conditions and maximum with standings. For it to even be capable of running at 1500 psi is going to require a high level of octane, normally a vehicle over 200 psi alone requires 97 or better octane. So it's a safe bet that 1500 psi or anything even remotely close is going to require 97 or better if not damn rocket fuel to run. the detonation is going to be drastically different then your normal car and 91 probably isn't even high enough of an octane to detonate.

in a literal sense yes, in a practical sense the higher the compression the higher octane levels are required.

The Acadia is the Saturn Outlook that was re-branded as the Acadia when GM shutdown the Saturn brand. My Mom had an Outlook that she traded in a few months back, and purchased the Acadia. She loves that car.

Quote:in a literal sense yes, in a practical sense the higher the compression the higher octane levels are required.That's to prevent knocking, high octane fuels are more resistant to combustion and thus more resistant to knocking which is essentially uncontrolled combustion. A proper engine management system can pretty much keep any engine from knocking regardless of power or fuel type. You can fill a Ferrari with regular fuel and it'll run just fine because the EMS will compensate.
Where high octane fuels might benefit this engine is with the supercharger. Since the fuel is more resistant to knocking the charger pressure can be increased without running the risk of knocking.

well you can put pure alcohol in an engine and it'll fire, for a little while. you certainly can't put 87 in a Ferrari and run it just fine, I would implore you not to try.
edit: the EMS your talking about controls how much fuel is sent through the injectors it does nothing to change the octane, ethanol or quality of fuel being delivered through the injectors. It'll pass pure water if you put it in the tank!

Did you know the higher the octane, the less combustible the fuel?
87 octane is more combustible than 92. Higher compression engines will backfire with low octane fuel because the explosion happens before the piston has topped out due to the higher compression.

You can't get 87 or 91 here. A Ferrari will run fine on 95.
